Organisational Structure
The project group has decided to use a simplified project organisation structure. The project group consists of 18 people and will be broken into 4 teams. The project group will adopt a democratic approach, so every team will be able to participate in the discussions and brain storming for each work package. Each team is responsible for gathering of information and ideas, and the compilation of the documents of 2 work packages.

1.0. Introduction Travelling to space is a complicated and difficult process because there are so many problems to solve and obstacles to overcome. Some of these problems to overcome when travelling to and from space shown below greatly affect the path we follow in order to achieve our objectives: • • • • • •
The vacuum of space Heat management problems Re-entry into Earth’s atmosphere Orbital mechanics Micrometeorites and space debris Cosmic and solar radiation
The following is a list of the possible transportation vehicles based on today’s available technologies, as well as some technologies that require periods of development. A brief list is given here, with short descriptions. The list is categorised into the following sections: • Conventional Vehicles • Alternate Vehicle Conventional Vehicles Rockets o VTOL Orbital Booster Conventional vertical take-off and vertical landing rocket engine booster with crew compartment on top of the rocket stack. Similar to boosters used in the Apollo, Mercury, and Gemini programs, and currently in the Soyuz program. This configuration is capable of achieving full orbital insertion with significant G-forces being felt by the passengers. The picture below in figure 3.6 is the Soyuz V rocket from Russia

o VTHL Orbital Configuration Conventional vertical take-off and horizontal landing rocket engine powered system similar to the dual-booster arrangement of the American shuttle orbiters. This configuration is capable of achieving a stable orbital insertion, as opposed to a sub-orbital trajectory. o VTHL Sub-Orbital Configuration Vertical take-off and horizontal landing rocket engine powered system. This vertical take off vehicle is designed only for sub-orbital flight, and hence as we have discussed has simplified requirements with regard to heat shielding, propulsion, and overall cost. Space Plane The Space Plane is a HTOL1 configuration incorporating dual propulsion systems. Jet engines are used to bring the craft to ceiling height, at which point a rocket engine is ignited, boosting the craft out of the atmosphere. Current technology allows for only sub-orbital flights. That is, the booster can only provide enough energy to push the craft outside the atmosphere for a matter of minutes before it 1

falls back to Earth. This restriction is related to the amount of fuel on board, as well as the weight of the craft. The picture below is the Space-Plane X33 which is based on horizontal HTOL take-off.

2STO Sub-Orbital Vehicle Two-stage to sub-orbit vehicle. Scaled Composite’s SpaceShipOne is an example of such a system. The space vehicle is attached to an advanced jet aircraft, capable of climbing to ceiling height with the vehicle attached. At this height, the space vehicle is released, and its own propulsion system is activated for a duration long enough to allow the craft to climb above 100km. It then follows a ballistic trajectory, incorporating aero-braking to facilitate a horizontal landing on a normal landing strip. The 2STO configuration has the advantage of requiring less fuel and weight onboard the space vehicle, as it ‘hitches a ride’ with the jet aircraft to ceiling height.
55
Alternative Vehicles Hybrid Jetpacks The use of jetpacks is proposed as a dual-craft configuration where passengers in Jetpacks are released from a Jet plane cruising at ceiling height. Rocket engines fitted to each jetpack then boost the passengers into a suborbital trajectory. The small size and weight reduces the requirements placed upon the boost rocket engine. This vehicle requires significant technological development in the form of initial investment to be successful. The inclusion of this vehicle type is for discussion purposes only, as it has a relatively low predicted viability. Space Cable Car The cable car is a novel technology that is not yet fully functional. Considerable initial investment would be required in order to utilise this technology in a space tourism application. It involves a cable link between the surface of the Earth and a satellite in geostationary orbit. The cable needs to have extreme structural integrity to withstand the large forces that are placed upon it. Passengers and cargo board a passenger transport on the Earth’s surface and the transport is then lifted into space along the cable.
1.2 Analysis Criteria for the Proposals Performance Measure: Safety Relative Importance: 1 This performance measure is defined as the public’s perception of the safety of a particular transportation method. Since the space excursion itself carries the same risks in the case of any space transportation vehicle, this performance measure is mostly effected by the launch and landing characteristics of the vehicle. Conventional systems such as vertical take-off and horizontal take-off2 craft score well due to the practiced nature of the technology. Since safety is a subjective measure that depends on the customer’s perception, the safety rank is simply assigned as a number from 1 to 9, with 1 indicating a less safe perception and 9 indicating the safest perception. Performance Measure: Flight Enjoyment Relative Importance: 2 Enjoyment is an important performance characteristic as on of the customer’s needs is for a ‘joyride’ into space, and hence the flight needs to be as enjoyable as possible. The nature of space flight dictates that the craft needs to be accelerated away from the Earth, perform on-orbit operations, and then return to the Earth. The forces exerted on the passengers during the return trip are proportional to the initial force that is exerted on the passengers during their acceleration to space. Therefore, the enjoyment index is calculated as a combination of the relative ascent time spent under acceleration, and the force exerted on the passengers during that acceleration. Flight enjoyment index = Ascent time under acceleration / Average force exerted on passengers during acceleration
Performance Measure: On-Orbit Enjoyment Relative Importance: 3 The second part of determining the enjoyment of the flight is the state of facilities available during on-orbit operations. This is related to the size of the transportation vehicle, which determines the amount of space available for such facilities as windows. Small capsule-like craft score poorly, while larger airline-style variants score well. It is also related to the maximum amount of people that the vehicle is capable of supporting at one time. 2
VTOL = Vertical take-off and Vertical Landing, HOTOL = horizontal take-off and horizontal landing
56
On-orbit enjoyment index = Size of crew compartment of vehicle / Maximum number of passengers that are to be accommodated in that compartment
Performance Measure: Initial Cost Relative Importance: 4 The predicted initial cost is the cost in $AUD required for the complete design and development of the transportation vehicle. This includes engineering design, review, prototype construction, subsystem testing, and final construction and testing.
Performance Measure: Time Provided In Space Relative Importance: 5 The time duration of the flight will determine if the passengers will experience the symptoms of being in space. It is related to the enjoyment measure, as higher levels of thrust will result in greater discomfort for the passengers, but will allow them to experience space for a longer period of time. This relationship saturates once sufficient energy to achieve orbital insertion has been achieved. Performance Measure: Cost to the End-User Relative Importance: 6 The predicted cost in $AUD per seat per passenger for one trip into space. The pioneering flights of Tito, Shuttleworth and Olsen came with a price tag of USD $20 million dollars, however current plans for sub orbital space trips come with predicted costs as low as $USD 20,000.

1.3 Analysis of Proposals The proposals introduced in section 1.1 would be analysed in detail with the analysis criteria specified in section 1.2
1.3.1 VTOL Orbital Booster Rocket Description: VTOL systems are currently implemented in the Russian Soyuz class spacecraft with excellent success. The Mercury, Gemini, and Apollo missions all used VTOL class launch vehicles. Since 1966 the most successful VTOL booster, Soyuz, has launched 750 times with a success rate of more than 97% [17]. Propulsion Type Score The VTOL system utilises a standard rocket engine possessing enough thrust to put the cargo into Earth orbit. The propulsion system consists of a liquid fuel that is ignited by an oxidiser, subsequently initiating a controlled explosion that releases enough energy to push the craft into orbit. Although such technologies are well developed in today’s space industry, the incredibly dangerous nature of the propellants is a severe safety concern. For this reason, we assign the VTOL rocket a Propulsion system score of 1. Launch Fuel Score The amount of fuel in a VTOL configuration at launch is the most out of any of the proposed vehicle types. The Soyuz rocket requires, on average, 160,000 kg of highly volatile kerosene and liquid oxygen propellant [20]. For this reason, we assign this launch vehicle with a fuel score of 0. Mission Goal Score The mission goal of an orbital VTOL configuration is Earth orbit. This makes the flight less safe as compared to a suborbital excursion as the spacecraft is subject to higher stress levels, as well as the challenge of re-entry [10]. For this reason we assign a mission goal score of zero. Physical Protection Score The physical protection provided by a VTOL configuration is relatively good. A capsule can be used to safely accommodate the passengers, as well as provide the required shielding to protect from cosmic radiation. We therefore assign the VTOL configuration with a protection score of 2 The overall safety score for the orbital VTOL vehicle is 2+0+0+1 = 3 Entertainment factor (Figures Based on the Russian Soyuz Booster [17]) Ascent Time under Acceleration = 500s Ascent Thrust = 4034 kN Launch Weight = 289,467 Kg Flight enjoyment Measure = 500s * (4034 kN / 289, 467 kg) = 6.967 Time in Space for VTOL Orbital Booster: 40 hours (2400 minutes) Flight Enjoyment Measure = 6.97 Space Experience Measure = 2400 / 6.97 = 344.3 Cost factor As of 1999, the mission cost for the Soyuz spacecraft launching aboard the R-7 VTOL booster was approximately AUD $53.2 million dollars, and hence the cost per passenger would be some fraction of this number, depending on the number of passengers aboard. If we disregard profit margins, a generalised VTOL 58
launch vehicle carrying 50 passengers at approximately AUD $50 million dollars per launch would deliver a cost of approximately AUD $1 million dollars to the end-user.
1.3.2 VTHL Orbital Vehicle The VTHL configuration has been solely applied in the American space shuttle orbiter. Designed to launch like a rocket and land like an aircraft, the Shuttle has flown 114 missions with a 98.25% success rate [18]. Since its inception in 1981, several possible flaws have been identified in the VTHL configuration, including the possibility of spacecraft damage during ascent due to debris from the booster rockets. Propulsion System Score The launch requirements for a VTHL configuration typically involve the use of a space orbiter craft attached to a booster system. In the case of the American space shuttle orbiter, the spacecraft is attached to an external fuel tank, which is in turn attached to two rocket boosters on either side of the tank. Also, the craft’s heat shield (an essential part of an orbital flight) is facing the boosters during flight, allowing any debris coming off the boosters to impact the heat shield, and possibly cause damage. Such damage was found to be the cause of the Columbia disaster in 2003 [19]. In review, modification of the orientation and protective measures of this vehicle type is possible, making this configuration highly useable with the appropriate safety modifications. However, the propulsion system still shares several dangerous characteristics with the VTOL launch vehicle. Hence, we assign a score of 1 here. Launch Fuel Score The launch fuel requirements for a VTHL configuration are the same as that for a VTOL vehicle. The vehicle must be fully fuelled at launch, with an average of 700,000 kg of highly volatile liquid hydrogen and liquid oxygen propellants for the American space shuttle [19]. The potential danger of these propellants at launch is exemplified by the Challenger disaster. Hence we assign a score of 0 here. Mission Goal Score The mission goal for a VTHL configuration is the same as that for a VTOL vehicle, and requires complete orbital insertion. Hence we assign a score of 0 here. Physical Protection Score The physical protection requirements for a VTHL configuration are the same as that for a VTOL vehicle, hence we assign a score of 2 here. The overall safety score for the orbital VTHL vehicle is 2+0+0+1 = 3 Entertainment factor Time in Space: 2400 minutes Flight Enjoyment Measure = 5.408 Space Experience Measure = 2400 / 5.408 = 443.7 Cost factor In a space tourism application with 50 passengers, a similar VTHL vehicle would be loaded with 50 passengers weighing approximately 100kg each, which is a total payload mass of 5000kg, one fifth of the standard shuttle launch mass. The launching cost would therefore be less by only a factor of approximately one tenth ($AUD 1 billion dollars), as less rocket fuel is needed, but more consumables such as oxygen are required to sustain the passengers and crew. With 50 passengers, and disregarding profit margins, the cost per passenger would therefore be approximately AUD $20 million dollars.

1.3.3 VTHL Sub Orbital Vehicle Propulsion System Score The launch requirements for a VTHL Sub Orbital configuration are the same as that for VTOL and orbital VTHL configurations, hence we assign a score of 1 here. Launch Fuel Score Since this vehicle needs only attain the required speed to push itself momentarily into space, the amount of fuel required at launch is greatly reduced. A comparison of the energy required for an orbital and suborbital flight reveals that approximately 32 times less energy is required to accomplish the latter [10]. However, since the VTHL configuration is using rocket propulsion throughout the entire flight, it will still require more fuel than a Space Plane or 2STO vehicle. Hence, we assign a score of 1 here. Mission Goal Score As discussed earlier, a suborbital mission goal results in a much safer flight due to simplified requirements in terms of speed, force, and re-entry. Hence we assign a score of 2 here. Physical Protection Score The physical protection requirements for a VTHL Sub Orbital configuration are the same as that for a VTOL and VTHL orbital vehicle, hence we assign a score of 2 here. The overall safety score for the VTHL suborbital vehicle is 1+1+2+2 = 6 Entertainment factor (Figures Based on the American Shuttle Orbiter [28]) Ascent Acceleration Time = 530 s Ascent Thrust = 34,000kN (This thrust is for the Space Shuttle with a 25,000 Kg payload delivery to LEO. Actual space tourism application with approximately 50 persons at 100Kg each = 5000 kg. Approximate thrust required = 10,000kN) Launch Weight = 5000 kg payload + 1,000,000 kg Weight of shuttle, boosters, and external fuel tank = 980,000 kg. Less fuel required for lighter payload is taken into consideration. Flight Enjoyment Measure = 530s * (10,000 kN / 980,000 kg) = 5.408 Time in Space = 5 minutes Flight Enjoyment Measure = 1.431 Space Experience Measure = 5 / 1.431 = 3.49 Cost factor Manufacturers of the ‘Ascender’ sub orbital booster are expecting to offer flights on their VTHL winged-booster rocket at a price of AUD $6500. It is a reasonable assumption that this price is indicative of most current VTHL sub orbital ventures.
1.3.4 Space Plane Propulsion System Score A space plane employs 2 propulsion systems. First, jet engines bring the craft to ceiling height, and then rocket engines ignite to push the craft into space. The fact that characteristically dangerous rocket propulsion is being used for only half the flight makes this approach the safest of all those we have considered. Hence, we assign a score of 2 here. 60
Launch Fuel Score Since rocket propulsion is only being used for half the journey, a relatively small amount of hazardous rocket fuel needs to be stored on board. However, jet engine fuel is still required in order to allow the Space Plane to reach ceiling height, and hence this takes away very slightly from the benefits created by the lack of rocket fuel. Hence, we assign a score of 1.5 here Mission Goal Score As is the case for the VTHL sub-orbital vehicle, the sub-orbital mission goal allows for a less complex and safer space flight. Hence, we assign a score of 2 here. 5.1.4.4 Physical Protection The physical protection requirements for a Space Plane configuration are the same as that for VTOL, and VTHL orbital vehicles, hence we assign a score of 2 here. The overall safety score for the Space Plane is 2+1.5+2+2 = 7.5 Entertainment factor Ascent Time Under Acceleration = 97s Ascent Thrust = 84.1 kN Launch Mass = 5,700 kg Flight Enjoyment Measure = (84.1 kN / 5,700 kg) * 97s = 1.4311 Time in Space = 3.5 minutes Flight Enjoyment Measure = 1.388 Space Experience Measure = 3.5 / 1.388 = 2.521 [21] 2005, ‘Suborbital Reusable Launch Vehicles and Emerging Markets’ Federal Aviation Administration and the Office of Commercial Space Transportation Cost factor Rocketplane Ltd. is planning on offering their sub orbital service aboard the Rocketplane by January 2007. The initial price per passenger for this sub orbital flight is expected to be approximately AUD $129,350 [21]. It is a reasonable assumption that this price is indicative of most current Space Plane ventures.
1.3.5 2STSO Sub-Orbital Vehicle Propulsion System Score A 2-stage to sub-orbit vehicle has similar propulsion system characteristics as the previously discussed Space Plane. In a 2STSO vehicle, the space transport unit is in a parasitic configuration, attached to a jet aircraft. 2 propulsion systems are used, and hence the safety of the approach is relatively good as a rocket engine is only being used for half the flight. The propulsion system for a 2STSO vehicle differs from a Space Plane in that the rocket engine needs only push a fraction of the weight of the combined aircraft. This means that, in comparison to the Space Plane, only a fraction of rocket propellant needs to be used to accelerate a 2STSO space vehicle into orbit, as it has far less weight than a Space Plane vehicle. Hence, we assign a score of 2 here. Launch Fuel Score As stated above, the amount of rocket fuel required by a 2STSO vehicle is considerably less than that which is required by a space plane. This increases the safety aspect of the 2STSO approach slightly. Hence, we assign a score of 2 here. 61
Mission Goal Score The sub-orbital mission goal allows for a less complex and safer space flight. Hence, we assign a score of 2 here. Physical Protection Score The physical protection requirements for 2STSO configuration are the same as that for VTOL, and VTHL orbital vehicles, hence we assign a score of 2 here. The overall safety score for the 2STSO vehicle is 2+2+2+2 = 8 Entertainment factor Ascent time under acceleration: 87s Ascent Thrust: 74kN Vehicle Weight: 3600 kg Flight Enjoyment Measure = (74 kN / 3600 kg) * 87s = 1.788 From the previous sub-orbital flights of SpaceShipOne, the average time spent in space is approximately 3.5 minutes Time in Space = 3.5 minutes Flight Enjoyment Measure = 1.788 Space Experience Measure = 1.957 Cost As we have discussed, Sir Richard Branson is entering into a venture in partnership with Scaled Composites to produce a SpaceShipOne variant for the purposes of conducting commercial sub orbital flights by 2007. The price per passenger for these initial flights is expected to be AUD $273,000 [27].
1.3.6 Hybrid Jetpacks Propulsion System Score This vehicle would use a combination rocket engine and reaction control thruster system (RCS) in order to perform a successful sub-orbital flight. A rocket engine would be required to boost the vehicle into space, and the RCS would be required for performing manoeuvres while in space. The propulsion system required here would have a high element of danger, as a fuel source of some description would be very close to the passenger. Also, it is reasonable to assume that that the rocket nozzle would be very close to the passenger also. The small size of the jet pack would necessitate the use of a relatively small rocket motor cone, and in essence would require the miniaturisation of most modern rocketry components. Even if this was completed within project schedule requirements, the proximity of the passenger to both the fuel source and the rocket nozzle makes this approach highly dangerous. Hence, we assign a score of 0 here. Launch Fuel Score When released from the aerial ‘mother ship’, the amount of fuel required to boost into orbit is very hard to quantify. Since this application of Jet Pack technology has not been previously considered, there is no reference material that can aid in this discussion. One can deduce that the relatively light weight of the vehicle, coupled with the limited space available for fuel storage, would allow us to conclude that there would be a relatively small amount of fuel required at launch for this configuration. Hence, we assign a score of 1 here. Mission Goal Score The sub-orbital mission goal allows for a less complex and safer space flight. Hence, we assign a score of 2 here. 62
Physical Protection Score This vehicle provides the least amount of physical protection from all the others we have considered. In a jetpack system, the passenger is exposed to micrometeorites and other space debris, as well as to cosmic radiation such as the Van Allen radiation belts. Since a considerable layer of shielding is required to protect against this radiation, this would considerably increase the weight and size of a jetpack system. Even with spacecraft-like shielding, there are limited provisions for the protection of vital life support systems and avionics systems. Hence, we assign a score of 0 here. The overall safety score for the hybrid jetpack vehicle is 0+1+2+0 = 3 Entertainment factor Ascent time under acceleration: 130s (similar to other sub orbital missions) Ascent Thrust = 3.5 kN (300 Kg mass overcoming the 9.81 m.s-2 acceleration of gravity) Vehicle Weight = 300 kg Flight Enjoyment Measure = (2.9 kN / 300 kg) * 130s = 1.51 Time in Space = 3.5 minutes Flight Enjoyment Measure = 1.51 Space Experience Measure = 3.5 minutes / 1.51 = 2.317 Cost If we continue with our two assumptions, firstly the AUD $1billion dollar development cost, and secondly that the Jetpack design will become a miniature 2STSO vehicle, we can calculate that the cost per mission will be similar to the 2STSO cost presented above. In addition to a portion of the development cost (which, we assume, will be passes on to the end-user), the total end-user cost will be (very) approximately AUD $300,000. 1.3.7 Space Cable Car Propulsion System Score The Cable car would utilise a revolutionary drive system to pull the car into orbit. A possible cable car configuration discussed in SPACEMART in 2001 described a Maglev system whereby the car is pushed into orbit by an advanced magnetic lift system. The propulsion system may utilise rocket technology, but on a much lower scale than the previously discussed vehicles. Hence we assign a score of 1.5 here. Launch Fuel Score Since the cable car does not predominantly use rocket technology to lift itself into space, the amount of fuel required will be small. Some fuel may be required for rocket engines that provide an initial momentary lift force, and this amount of fuel will be very small in comparison to the other vehicles we have discussed. Hence, we assign a score of 2 here. Mission Goal Score The mission goal for a Space Cable Car vehicle is the same as that for a VTOL and VTHL vehicles, requiring complete orbital insertion. Hence we assign a score of 0 here. Physical Protection Score Passengers are relatively well protected inside the car, as it can be large enough to afford spacecraft-like shielding and other important physical protection means. The cable itself is highly vulnerable to damage that may be caused through likely collisions with space junk and other objects. A tear in the cable would be a catastrophic event, as the cable is the means by which the car is secured, and if the cable broke there is a possibility that the car would be lost. Hence, we assign a score of 0.5 here. The overall safety score for the Space Cable Car = 1.5+2+0+0.5 = 5 63
Entertainment factor Vehicle Weight: 20,000 kg Flight Enjoyment Measure = (196kN / 20000kg)*7200s = 70.56 Time in Space = 2400s Flight Enjoyment Measure = 70.56 Space Experience Measure = 34.013 Cost Below are the approximate running costs for the space elevator proposed by Dr. Brad Edwards [24]: Annual Operating Budget per year in US$M Climbers 0.2 - 2 each Tracking system 10 Anchor station 10 Administration 10 Anchor maintenance 5 Laser maintenance 20 Other 30 TOTAL (50 launches)
135
The data presented quotes a USD $135 million dollars (AUD $175.5 million dollars) annual expenditure for a 50-mission year, resulting in a cost of $AUD 3.5million dollars per mission. Disregarding profit margins, and assuming a 50 passenger crew, this would result in a cost per passenger of approximately AUD $70,000.

Assigning Value Curves Value curves allow us to define the relationship between an increase in the quality of a certain performance measure and the amount of value added to the system. The shape of each of the value curves defines a different relationship between these two quantities, and the equations describing the graphs can be used to calculate an adjusted ranking. Vehicle Safety As vehicle safety is decreased, the reliability and marketability of the system is decreased. Therefore, the system value will drop exponentially, and hence the increasing RTS curve is chose, as shown below.
Increasing RTS [30]: Calculated equation = v(x) = -x0.5+1 The values for vehicle safety were computed and it is represented in table 6 below.

Table 6: Rankings and Value Curves
This performance measure has similar behaviours to the previous measure, in that a decrease in the customer’s perception of vehicle safety will result in an exponential decrease in the system’s value. Hence we choose the increasing RTS value curve, which is shown above. Flight Enjoyment High flight enjoyment will maintain the ‘joyride’ aim, and serve to keep the system viable for all customers. Undesired levels of flight enjoyment will decrease system value exponentially. Therefore we choose the increasing RTS curve Space Experience Enjoyment This performance measure exhibits similar behaviours as the previous Flight enjoyment measure, and hence we will use the increasing RTS curve. Development Costs High development costs mean that the overall system value will be reduced. As development costs are reduced, the system value increases linearly. Hence, we use the Linear RTS value curve shown below:

Linear RTS [30]: Calculated equation: y = x End User Cost Per Seat The most desired value here corresponds to the lowest end-user cost. However, if the end-user cost is too low the venture will not be viable. Also, if the end user cost is too high, then interest in the venture will be low. Hence, there exist a point in equilibrium which accomplished both these objectives, and this relationship is shown by the s-curve below:

Storage of maintenance equipment The ground terminal maintenance hangar is used to store all equipment and facilities to be used in the maintenance of a space transport unit. This function was defined as F_6.3 in the functional analysis and includes all three levels of maintenance, those being basic level, intermediate level and advanced level maintenance services. Two feasible options were presented in regards to the storing of maintenance equipment, these were: 1) Space transport unit storage hangar 2) Ground terminal maintenance hangar Although any space transport unit would spend the majority of its time in the space transport unit storage hangar, it was decided that the more suitable option would be to construct another hangar designated solely for maintenance. Hence the ground terminal maintenance hangar was chosen to be implemented for this reason. To have a maintenance operation that is separate to the storage system has one key advantage, this being that all maintenance operations are carried out away from space transport units which do not require maintenance which in turn reduces the likelihood of an overcrowded workplace for the maintenance staff. Although the cost of constructing two separate hangars will be larger, the advantages of applying the separation between storage and maintenance will outweigh the initial cost burden.
Disposal System The system lifecycle is highly dependant on the effectiveness of the disposal system. The disposal system is not only used at retirement but also used in the sustainability of the project. The disposal system encompasses three aspects of waste from any retiring / failed equipment, these being hazardous waste, recyclable waste and non recyclable waste as defined in F_7.0. The disposal system is responsible for the separation and the eventual disposing of all products which are no longer required in their current function. The disposal system will therefore cover not only the space transport unit but also the ground terminal and all other supporting facilities. The disposal system could be operated in two ways as described below: 1) Disposal carried out internally
203
2) Disposal carried out by a hired company There are obvious advantages and disadvantages to each of these solutions. Cost is of high importance in all business areas however, the hiring of an external company to remove any waste would be advantageous with regard to any government regulations. For example the employment of a professional waste removal company would eliminate the need for our system to comply with the associated government regulations which are required to be met when dealing with hazardous waste products. The recycling of useful parts however would be more easily accomplished within the system as this can include small tasks which maintenance staff employees are capable of achieving. With this in mind the solution to a choice of waste management through disposal of the system is best suited to be undertaken internally. This eliminates the cost of hiring an external company and also allows recyclable waste to be reused or sold more efficiently as described in F_7.1, F_7.2 and F_7.3.
Space transport unit storage hangar The space transport unit must be stored in a hanger when not in use. The appropriate hanger must be used to cater for all space transport vehicles and for the weather conditions. As defined in function F_1.4.2 The system requirements state that the ground terminal shall have a hangar capable of storing at least 5 space transport units. With the space transport units having the following dimensions: Wing span: 28.4m Overall length: 37.8m Tail height: 8.9m With these dimensions the hangar must be 62mtr × 209mtr × 15mtr , this gives sufficient clearance for the height of the vehicle and 2 meters of space around each vehicle for movement. Hangar Style It is necessary to have the correct hangar style for the space transport unit, the typical styles are as follows. -Segmental Tied Hangar The segmental tied hangar is constructed of segmental tied trusses which are able to span up to 200m or more.
204
-Glove Hangar Glove hangars are an economic solution to aircraft storage, where economy is achieved by the hangars fitting tightly around the aircraft. This reduces the amount of materials used and inturn lower costs. The doors are customised to fit specific aircraft and the nose/fuselage section of the hangar is reduced in size. The smaller internal space also makes the building cheaper to cool or heat. This design does not cater for the space transport unit. The small dimensions only allows for one Space Transport Unit, this would mean that at least 5 hangars are to be constructed for all space transport units to be stored, it would also be difficult to perform maintenance on the space transport unit due to its fitting nature.
-Spine Truss Hangar Spine truss hangars have the dimensions of very short and wide. It is a cost effective solution, however it would not be able to cater for the Space Transport Unit due to the shallow depth of the hangar.
-Cantilever Hangar Cantilever hangars are ideal mostly for long extensions. It needs a substantial office/workshop zone behind the hangar to act as a counterweight. The hangar can extend as long as one kilometre but is restricted to the length/size of the office/workshop behind the hangar. This option would seem feasible since it is cost effective and meets the
205
required dimensions for the Space Transport Unit storage, however it is not know whether the counterweight building behind the hangar has the required length for the size of the hangar.
-Butterfly Hangar The butterfly hangar is made for time efficiency. It needs an apron on both sides, which allows fast access to the stored vehicle. This design is a possible option, however the cost of the butterfly hangar is higher than other designs.
Hangar Roofing/Wall Cladding The material the hangar is composed of is necessary to analyse. It shields the Transport Unit from environmental effects and gives it security and protection. It is desirable for the temperature of the hangar to be kept at a constant room temperature. This will decrease expansion/contraction of the facility and will be an easier environment to work in. There are three different types of roof/wall cladding for different situations. Single Skin Single skin sheeting is the most economic material suitable for roof/wall cladding. It is composed of a single layer of metal over the steel frame, providing little insulation. The single skin is a possible option, however it lacks insulation therefore the hangar will reach high temperatures when it is hot and low temperatures when it is cold. This is an undesirable effect. Double Skin Double skin sheeting is a more expensive material. It is composed of an outer material made of galvanised iron with a small insulation gap and a fibre glass inner skin. It reduces condensation, temperature change and the chance of leakage. It is the most cost effective solution for insulation.
206
Composite Double Skin The Composite Double Skin provides more insulation than the double skin. It is composed of a sandwich panel with a foam core for insulation. It is more expensive than the double skin but is a greater insulator. Design Criteria for Space Transport Unit Storage System While all hangars were analysed only the segmental tied hangar and the butterfly hangar were physically able meet the size requirements of the Space Transport System. The advantage of the segmental tied hangar is the financial cost while it may take longer to get to the runway. While the butterfly hangar has a significantly higher cost however allows efficient transport due to aprons being on both sides. The Space Transport Systems flights are not as regular as normal flights therefore time efficiency is not a great factor. Therefore the segmental tied hangar is preferred. From the three skin materials the most effective when taking strength, insulation and cost into account is the Double Skin. It is a mid ranged material that provides adequate insulation with a U value from 0.45W/oC/m2 - 0.2W/oC/m2. The composite double skin is a more expensive alternative however the cost is significantly higher for a small difference in insulation. While the single skin provides an insignificant amount of insulation.
Ground terminal maintenance hangar The Ground Terminal maintenance equipment must be stored in a maintenance hanger when not in use. The appropriate hanger must be used to cater for all ground terminal maintenance equipment and for the weather conditions. The system requirements state that the Ground Terminal maintenance hangar shall store all ground terminal maintenance equipment and have the dimensions of at least 100mtr × 150mtr × 15mtr . As defined in functional analysis F_1.4.2 The maintenance hangar must be kept at a constant temperature of 25oC this is to maintain the life of the equipment and allow for a comfortable working environment. Therefore the skin material for the roofing and wall cladding must have insulation. The room must also have air conditioning and heating to assist temperature control. Hangar Roofing/Wall Cladding The material the hangar is composed of is necessary to analyse. It shields the maintenance equipment from environmental effects and gives it security and protection. It is desirable for the temperature of the maintenance hangar to be kept at a constant room temperature. This will decrease expansion/contraction of the facility, prolong the equipment life and will be an easier environment to work in. There are three different types of roof/wall cladding for different situations.
207
Double Skin Double skin sheeting is a more expensive material. It is composed of an outer material made of galvanised iron with a small insulation gap and a fibre glass inner skin. It reduces condensation, temperature change and the chance of leakage. It is the most cost effective solution for insulation. Composite Double Skin The Composite Double Skin provides more insulation than the double skin. It is composed of a sandwich panel with a foam core for insulation. It is more expensive than the double skin but is a greater insulator. Design Criteria for Space Transport Unit Storage System From the two skin materials the most effective when taking strength and insulation into account is the Composite Double Skin. It is provides higher insulation than the double skin but at a higher cost.
Security of the space transport unit hangar For security surveillance of the space transport unit hangar, there are 2 kind of feasible security surveillance systems that could be considered for this application, these are: 1) The use of CCTV surveillance 2) 24 hour security guards CCTV (Closed-circuit television) is a television system that uses surveillance cameras to do the video surveillance. The CCTV is different from broadcast television in that all components are directly linked via cables. The use of CCTV is to deter unauthorised people from entering into the space transport unit hangar at all times. However the CCTV also can be placed in remote area or surround the space transport unit hangar which enables the premises to be monitored at all times. An advantageous function of the CCTV is that, it can record the entire area at all times giving us the best surveillance. We can then play back the recording to see what had happened before. With function of zoom, we can see more clearly, which can help police to identify intruder. The CCTV can provide surveillance 24 hours non-stop everyday, this will provide 24 hours safety of the space transport unit hangar. With advances in technology nowadays, we can install a security door which can be used to restrict unauthorised person to enter to the space transport unit hangar. The security door can design to scan the person’s identification card, fingerprint, eyes, and etc. Because of the CCTV surveillance and security doors, we can leave the space transport unit hangar without the need for a security guide to keep it safe 24 hours a day.
208
Security guards can keep the place safe, but they couldn’t provide complete surveillance for all of the surrounding area at the same time. It is unfeasible to employ large numbers of security guards to surround the space transport unit hangar at all times, this is just wasting manpower and in turn money. The safety they provide can not be guaranteed at 100%, because the guards are capable of human error. This is why the use of CCTV is the recommended solution to security.
209
Fuel Storage Storage of fuel for the space transport units is vital in the safety and efficiency of the entire system. Although many options for fuel storage are available we can narrow our analysis down to the use of fuel tanks and more precisely whether they are located: 1) Above ground 2) Below ground In a similar fashion to any regular fuel station the choice was made to go ahead with the plans for below ground fuel tank construction. The fuel storage facilities consist of fuel pumps and underground tanks located under the ground terminal. The facility makes the fuelling process more convenient. It allows more space transport units to re-fuel at the same location without wasting any time. Fuel storage systems were placed underground for three primary reasons: • • •
Reduce fire and explosion risks. Reduce evaporation losses. Reduce condensation problems
Furthermore, problems like rain or surface water accumulation in the impervious containment systems can be avoided. Surrounding buildings to the fuel storage system could be the Ground terminal, hangars, launching base etc. Fuel is highly combustible. It can results in serious fires and explosions which will damage the surrounding buildings or cause severe injury to people. The chances of fire or explosion can be reduced by following safety precautions and by keeping fuel storage facilities in top condition. Large amounts of fuel are needed to operate the space transport units. The storage tank should be able to store such amount in order to ensure that fuel supply is always ready for space transport unit. Hence an underground system is more appropriate than an above ground system as the large tanks are hidden as compared to taking up space on the surface where hazards could occur.
Life Support System Atmosphere The SiO2 Tiles: These tiles protect the spacecraft upon re-entry into earth’s atmosphere. The space shuttles are protected by special silica tiles. Silica (SiO2) is an incredible good insulator. It is possible to hold a space shuttle tile by the edge and then heat up the centre of the tile with a blow torch. The tile insulates so well that no heat makes it out to the 210
edges [4]. The Silica titles are the best option to fulfil this requirement, as per they have been widely in use before, have no reliability issues and have no competition. Temperature Space temperatures have extremely cold weather conditions and it is constantly changing in different parts of the orbit. However, the electronic equipment generates more than enough heat for the ship. The problem is getting rid of the unwanted heat and do that we need temperature control system have to these major functions. •
Distribute heat where it is needed on the orbiter (mid-fuselage and aft sections) so that vital systems do not freeze in the cold of space [10].
•
Electrical heaters - use electrically-heated wires like a toaster to heat various areas [10].
•
Active methods - more complex, use fluid to handle large heat loads, require maintenance [10].
•
Cold plates - metal plates that collect heat by direct contact with equipment or conduction [10].
•
Heat exchangers - collect heat from equipment using fluid. The equipment radiates heat to a fluid (water, ammonia) which in turn passes heat on to Freon. Both fluids are pumped and recirculated to remove heat [10].
•
Pumps, lines, valves - transport the collected heat from one area to another.
•
Radiators - located on the inside surfaces of the cargo bay doors that radiate the collected heat to outer space [10].
•
Heat released from the Freon causes the ammonia to boil [10].
Because these methods have been used and tested by NASA. Therefore is no other better solution of our currently technology are better and more efficiency therefore our system will use them the same way as NASA does. Pressure The airlock is normally located inside the mid deck of the spacecraft's pressurised crew cabin. It has an inside diameter of 63 inches, is 83 inches long and has two 40-inchdiameter D-shaped openings that are 36 inches across. It also has two pressure-sealing hatches and a complement of airlock support systems. The airlock's volume is 150 cubic feet. Airlock pressurisation is controllable from the orbiter crew cabin mid deck and from inside the airlock. It is performed by equalising the airlocks and cabin's pressure with equalisation valves mounted on the inner hatch. The airlock is depressurised from inside the airlock by venting the airlock's pressure overboard. The two D-shaped airlock hatches open toward the primary pressure source, the orbiter crew cabin, to achieve pressure-
211
assist sealing when closed [11]. Due to NASA’s air-lock system already in use in most spacecraft, its seems the most logical answer to this requirement as it has been used widely before and has no reliability issues and has no competition. Crew compartment cabin pressurisation The cabin is pressurised to 14.7 psi, plus or minus 0.2 psi, and maintained at an average 80-percent nitrogen and 20-percent oxygen mixture by the air revitalisation system. Oxygen partial pressure is maintained between 2.95 and 3.45 psi, with sufficient nitrogen pressure of 11.5 psi added to achieve the cabin total pressure of 14.7 psi, plus or minus 0.2 psi. The pressurisation system consists of two oxygen systems and two gaseous nitrogen systems. The two oxygen systems are supplied by the PRSD oxygen system, which is the same source that supplies oxygen to the orbiter fuel cell power plants. The PRSD cryogenic supercritical oxygen storage system is controlled by electrical heaters within the tanks and supplies the oxygen to the ECLSS pressurisation control system at a pressure of 835 to 852 psi in a gaseous state. The gaseous nitrogen supply system consists of two systems with two gaseous nitrogen tanks for each system. The nitrogen storage tanks are serviced to a nominal pressure of 2,964 psi at 80 F. If the auxiliary gaseous oxygen supply tank is installed, it is serviced to 2,440 psi at 80 F and stores 67.6 pounds of gaseous oxygen to provide high flow along with gaseous nitrogen. It would maintain the crew cabin at 8 psi with oxygen partial pressure at 2 psi. For normal on-orbit operations one oxygen and nitrogen supply system is used. For launch and entry both oxygen and nitrogen supply systems are used in addition to pressurisation of the airlock [11]. Because crew compartment cabin pressurisation is the most excellent and the only pressure system that are currently been used to maintain an atmospheric pressure by NASA. Therefore is no other better solution of our currently technology are better and more efficiency therefore our system will use them the same way as NASA does.
Space transport unit exterior Silica Fibres The silica fibres are derived from common sand and are made of high purity fibres (2 to 4 microns in diameter, as long a 1/16th inch) derived from common sand. The tile containing silica fibres is frame cast to form soft, porous blocks to which a colloidal silica binder solution is added. The blocks are then dried, sintered at 2300ûF. Machined tiles then go to ovens for baked-on coatings. These tiles experience re-entry heating up to 2300ûF and are coated with white silica compound which includes alumina to better reflect the heat of the Sun on-orbit. All tiles are treated with a waterproofing polymer [13]. High temperature reusable surface insulation tiles
212
This HRSI tiles are made from a low density and high purity silica 99.9% and fibres are derived from command sand of 1 to 2 mils tick. The insulation that made ridged by ceramic bonding. The weigh of this tiles about 9 pounds per cubic foot. The thickness is determined by the heat load encounter during entry. HRSI tiles are vary in size and shapes in the close out areas on the orbiter. The HRSI tiles withstand on orbit cold soak condition and repeated heating and cooling thermal shock and extreme acoustic environments about 165 decibels at launch. Because HRSI tiles are small, have been used widely, and are reliable and safe, these are to be used. For the controller, because a NASA air- system has been widely used before has no reliability issues and has no competition; this system is to be used.
Space Navigation Space vehicle navigation comprises two aspects: (1) Knowledge and prediction of the space vehicle’s position and velocity, which is orbit determination, and (2) Firing the rocket motor to alter the space vehicle’s velocity, this is flight path control. The primary system used throughout the world for space-based positioning, navigation, and timing is the Global Positioning System (GPS), a constellation of satellites providing continuous civil service free of direct user charges to an unlimited number of users for peaceful purposes. Additionally, GPS is critical to a wide range of civilian activities and represents a fundamental component of the global information infrastructure [15]. Figure 1.1 below shows the locations of the existing placements of GPS systems.
To determine the orbital position of the space vehicle, the imaging instruments on board the vehicle can use them to observe the spacecraft's destination planet or other body, such as a satellite, against known landmarks. The observations are carefully planned and up linked far in advance as part of the command sequence development process. The primary body often appears in these images, which are known as opnavs, so that the background stars will be clearly visible. When the opnav images are down linked in
213
telemetry (TLM) they are immediately processed by the navigation team. Interpretation of opnavs provides a very precise data set useful for refining knowledge of a space vehicle’s trajectory as it approaches a target, or otherwise addressed as flight control. There are several types of navigational systems that could be used for space navigation. This comprises of: 1) 2) 3) 4) 5) 6)
Galileo satellite navigation GLONASS navigation system Quasi-Zenith Satellite System Beidou satellite navigation Euridis navigation Multifunctional Transport Satellite (MTSAT-1R)
The Galileo satellite navigation program is a joint initiative between the European Union and the European Space Agency to build and operate a 30-satellite constellation that provides similar capabilities to GPS, but as a commercially-operated, for-profit venture, not a public good. The system will offer four distinct positioning, navigation, and timing services and one search and rescue service. GLONASS is a Russian space-based navigation system comparable to the U.S. GPS system. The fully operational system will contain 21 satellites in 3 orbital planes, with 3 on-orbit spares. The GLONASS system is managed for the Russian Federation Government by the Russian Space Forces providing benefits to civil users through a variety of applications. The GLONASS system has two types of navigation signals: standard precision navigation signal (SP) and high precision navigation signal (HP). SP positioning and timing services are available to all GLONASS civil users on a continuous, worldwide basis. On December 10, 2003, three GLONASS spacecraft were placed into orbit in Plane 1, including one of the new generations of GLONASS-M satellites. The addition of these three satellites will bring the GLONASS constellation to a total of 11 operational satellites. The Quasi-Zenith Satellite System [Jun-Ten-Cho in Japanese] is a constellation of at least three satellites, configured such that one of them is always positioned at a high elevation angle over Japan. RF transmission will not be obstructed by tall buildings or mountains, because one of satellites will always remain near high in the sky over Japan at all times. As a result, signal degradation caused by building blockage and multiple signal paths will be less frequent, making the whole system ideal and reliable for mobile data communication and broadcasting. The system is also expected to increase accuracy to GPS users in the eastern Asia area. Although China has not yet established operational satellite navigation and positioning network, research for such a system has been underway for many years, and a future space-based navigation capability is an acknowledged goal. Beidou ('Big Dipper') is the satellite component for the independent Chinese satellite navigation and positioning system. The Beidou satellite navigation and positioning system are consists of two
214
satellites in geosynchronous orbit. The final Beidou constellation will include four satellites, two operational and two backups. Together with the ground stations, the Beidou system will provide navigation and positioning signals covering the East Asia region. However, to provide global signal coverage, satellites flying in other orbits around the world must complement the system. The Euridis satellite navigation system developed by Alcatel Space, as Prime Contractor, provides France's initial contribution to the EGNOS programme, the European component in the first-generation worldwide navigation satellite system (GNSS-1). The system was ordered by CNES. In the context of the EGNOS programme, Euridis provides users with a permanent navigation signal in addition to those supplied by the GPS (American) and GLONASS (Russian) constellations. This signal significantly increases the availability and integrity of the user's position. Euridis navigation service will be available in the Inmarsat 3 AOR-E satellite footprint area [18]. The Multifunctional Transport Satellite (MTSAT-1R) multi-mission space programme comprises a space segment which will eventually consist of two geostationary satellites and an earth segment. Alcatel Space is playing a leading role in this aeronautical mission and in the production of traffic and earth control stations [18]. MTSAT-1R is being built for Japan and will be the first air navigation and telecommunications space system to meet the CNS/ATM concept adopted by the International Civil Aviation Organisation (ICAO) in 1991. Design Criteria for Space Rocket navigational System For the joyride to Space program, there are 2 feasible navigational systems that could be considered for this application, namely: 1) Galileo satellite navigation 2) Euridis satellite navigation system While most of the other satellite navigational systems are publicly offered, the Galileo has a 30-satellite constellation, which offers the most coverage among other satellite navigational system. The added feature making this navigational system attractive is also the ability to provide a search and rescue service, which is an added safety feature. However, the cost factor needs to be addressed when choosing this system as it is a commercial package. The Euridis satellite navigation system takes advantage over the other two by combining both the GPS (American) and GLONASS (Russian) constellations. However, it does not provide search and rescue services.

Radio communications In voice communication, space transport should provide communication via UHF and HF transmission allow to transmitting data between space transport and ground. All voice in HF frequency is in AM mode. The UHF transmission provided high transmission rate which for voice and video communication. There are some frequencies which need to consider for UHF transmission provided by Scott [19]: a. 1831.787 - US Dept of Defence Uplink to Space Shuttle[19] b. 2085.6875 - S Band Uplink to Space Shuttle [19] c. 2106.4 - Command Uplink [19] d. 2119.8 - Space Shuttle - Payload Link Frequency [19] e. 2217.5 - TDRS Satellite link [19] f. 2250.0 - WFM - Analog Data and Telemetry during Space Shuttle Launch [19] g. 2265.0 - S Band Downlink [19] h. 2287.5 - ISS Zarya Module / Space Shuttle [19] i. 2298.8 - Payload - Space Shuttle Link Frequency [19] We have chosen the option ‘i’ because the higher frequencies range of transmission, the more efficiency data transmission on communication. Therefore, this would be providing customers to enjoy quality and high performance of voice and video communication between ground and space transporter. However, there are some HF frequencies provided by Scott [19] which is showed below: a. 8.364 - Morse Code heard during recovery of Russian Space Vehicles b. 9.019 - AM - Used for Vostok 1 [19] c. 10.003 - Common Recovery Beacon frequency [19] d. 15.008 - AM - Early Salyut / Soyuz [19] e. 15.016 - AM - Mercury 7 Frequency [19] f. 15.763 - AM - Used for Vostok 2 [19] g. 17.365 - AM - Used for the Voskhod missions [19] h. 18.035 - AM - Used for Voskhod / early Soyuz missions [19] i. 18.060 - AM - Old Soyuz frequency / Used During recovery of Russian [19] We found that the HF feasible frequencies for HF transmission are 15.016 MHz. The reason to choose this because it is been used in space craft called “Mercury 7” and we decide our space transporter is more suitable using this frequencies band which is 15.016 MHz in AM mode for voice communication.
Video Communications The space transport should provide at least 12 inches of LCD monitors for video communication. We decided to use 12 inches of LCD screens monitors which able to send quality video images according to specification of LCD monitors provided by Caltron Industries [20]. The following specification is showed as below:

Communications Antenna The space transport communications system should have at least 2 antennas for tracking the signal from ground to space transport. The function of antennas is to receive and transmit the data between ground and space transport. According to ATCI [21], there is specification which related to antenna on space transport: For Simulsat 5 • Most Frequently Installed Model Worldwide • Standard and High Mount Available • C and Ku-Band Capability • Performs equivalent to 4.5 m. C-Band Prime Focus Parabolic Antennas • Receives, with uniform performance, signals from all satellites within a 70° view arc. • Requires Less Space – Takes up the same space as 3 parking spaces.
217
For Simulsat 7 • ATCi’s largest Simulsat model – geared toward large cable systems and teleports. • Standard and High Mount Available • More arc coverage – receives, with uniform performance, signals from all satellites within a 75° view arc. • C and Ku-Band Capability • Performs equivalent to 6 M. C-Band Prime Focus Parabolic Antennas. We decided to use Simulsat 7 because it is more reliable and able received strong signals. Therefore, it might improve the data transmission as well.
Tracking system The space transport communication system provides a tracking subsystem via C-band. According to Telesat [22], there is some specification which provided as following: Option 1
Option 2

We have chosen option 1 because the power consumption is less and the C-band channel will be equally same as option 1. So, there might cut the cost also to build tracking system via C-band.
Space to ground tracking system The space to ground communication provides tracking system via S-band. Paul J. Marsh [23] defined the definition of S-band is the range of frequencies from around 1.55 GHz through to 3.9 GHz. There is other more well knows devices that transmit at s-band. These include microwave ovens on 2.450 GHz, and the new breed of wireless videosenders which also operate around the 2.4 GHz mark. Other services to be found include video downlinks from police helicopters, outside broadcast events and blimp type balloons with cameras on board. The initial success of the helical antenna for L-band led me to redesign the antenna for s-band. After spending some time researching the various downlinks on s-band, a left hand circular antenna was build to feed the dish, resulting in right hand circular reception. The advantage of the helical is its wide bandwidth, having a minus 20% and plus 30% bandwidth with respect of the design frequency. The centre 218
frequency I chose is 2.25 GHz, so the antenna will be usable from 1800 MHz to 2925 MHz. This is quite wideband, but I'm using it round the 2.2 GHz mark, with about 200 MHz either side. This picture is not of a helical but of the S-band dipole used to test. [23]
Figure 3: Example photo captured by S-band satellite. (Courtesy by Paul J. Marsh )[23] From here, our team decided to use the tracking system for S-band compared to other bands due to costly and low quality resolution of images which performed from other bands. It provides a very clear picture which captured by using S-band satellite.
Propulsion subsystem The propulsion system is required to be able to provide at least 95kN of thrust. The TX354-3, RL-50, Airane-HM-7B, Vinci, and Vulcain, all meet this requirement. From the specifications we have chosen to use the Vinci Engine. Vinci Designer: Astrium. Propellants: Lox/LH2 Thrust(vac): 15,700 kgf. Isp: 467 sec. Chambers: 1. Country: Germany.

The Vinci specification more closely matches the thrust we require 155kN compared to 200+ for the other engines. This engine will provide enough thrust to lift the Space transport unit to space and accelerate at a speed which is comfortable for the passengers. It also has an additional safety feature of being able to be restarted during flight. The Specifications for the Engines can bee seen below in Figure Engine1. Applications Schedule Dry Mass Length Max Diameter Mounting Method Oxidiser Fuel Mixture Ratio Turbo pump Isp Thrust Cooling Method Combustion Chamber Pressure Combustion Chamber Ignition Remarks

Table Propulsion1- Main engine Vinci Specifications The thrusters for the propulsion system will be used to maintain the stability of the space transport unit. The Thrusters we have considered are the DOK-10 and CHT-5. DOK-10 Designer: Isayev. Propellants: Hydrazine Thrust(vac): 1 kgf. Thrust(vac): 0.010 kN. Isp: 229 sec. Burn time: 1,500 sec. Mass Engine: 1 kg. Chambers: 1. Chamber Pressure: 10.00 bar. Area Ratio: 46. Thrust to Weight Ratio: 1.7. Country: Russia. Status: In Production. CHT-5 Designer: EADS. Propellants: Hydrazine Thrust(vac): 0.006 kN. Isp: 228 sec. Mass Engine: 0.22 kg. Chambers: 1. Chamber Pressure: 22.00 bar. Country: United States. Status: In Production.
Both thrusters are fuelled by Hydrazine and are able to provide the required thrust. We have chosen to use the CHT-5 thrusters as they are lighter in weight. This enables us to be more fuel efficient and decrease total running costs of the transport unit. Specifications can be seen in table Space2
220
Table Propulsion2. Thrusters Specifications CHT-5
The propellent used to fuel the Engines in Liquid Hydrogen and liquid Oxygen. The propellent used to fuel the thrusters is Hydrazine. Fuel is required to be kept storage tanks that comply with any government regulations and safety procedures relating to the handling and storage of such chemicals. These tanks are required to be large enough to accomplish 1.5 space flights.
Launch system runway According to Simon Rowland [1], for a 200 passenger space transport, the space transporter runway should withstand 830 tonnes, Our team has decided to withstand approximately 850 tonnes on the runway. The runway should be able to take all specifications and requirements such as runway shall at least withstand a static weight of 120 tonnes. According to Sydney airport [1], two runway surface specifications which are RWY 07-25 and RWY 16L-34R showing the following: RWY 07-25 (Option 1) Width: 45 m Length: 2529 m Pavement: Asphalt/Flexible Subgrade: High Strength Characteristics: Grooved RWY 16L-34R (Option2) Width: 45 m Length: 2438 m Pavement: Asphalt/Flexible Subgrade: High Strength Characteristics: Grooved
221
Refer to both runways above, our team has decided that option 2 is more reliable and easy to maintain runway. Therefore, the characteristic of runway shall be treated with groove skid resistant material and the length of the runway shall be approximately in 2.5 Km.

1. INTRODUCTION A Portfolio divides teams into different aspects where each team then contributes towards the final outcome of the project. These teams contribute a collection of documents describing their perspective towards the project. These documents describe in detail about each requirement. Taken from the requirements, it has been broken down to each sub-section and explained in more detail the purpose of the requirement from each aspect, which is the technical part, the non-technical part, the safety
part and the system aspects part. A detailed explanation from each of these sections provides a clear view of the purpose of the requirement.
2. Navigation Portfolio Identifier: PORT_01 Requirement: The system shall provide two-dimensional (latitude and longitude) coverage of the space transport unit in space. Technical: Latitude measures the angle ranging from 0° at the Equator to 90° at the poles and the longitude is also measured in angles ranging from 0° at the Prime Meridian to +180° eastward and −180° westward Latitude measures the angle ranging from 0° at the Equator to 90° at the poles and the longitude is also measured in angles ranging from 0° at the Prime Meridian to +180° eastward and −180° westward The latitude and longitude coverage will provide the space transport unit’s co-ordinates to the ground station. Safety: The co-ordinates will enable the ground station to track the space transport unit’s position. Tracking the space transport unit is for safety precautions in case any incidents may occur, so emergency and rescue services could perform efficiently if the exact locations of events are known. Non-Technical: The two-dimensional co-ordinate system is required as a safety precaution. System Aspect: The two-dimensional co-ordinate system is required to be part of the navigation system, mainly for the safety of the public, customers and employees, and also as security for the space transport unit. Portfolio Identifier: PORT_02 Requirement: The system shall provide three-dimensional altitude coverage of the space transport unit in space. Technical: The three-dimensional altitude provides the location on, in, or above the Earth, the elevation, and the height position of the space transport unit. The threedimensional coverage will provide the location, the elevation and the height position of the space transport unit to the ground station. Safety: The three-dimensional altitude coverage will enable the ground station to track the space transport unit’s altitude position. Tracking the space transport unit is for safety precautions in case any incidents may occur, so emergency and rescue services could perform efficiently if the exact locations of events are known. Non-Technical: The three-dimensional altitude system is required as a safety precaution. System Aspect: The three-dimensional altitude system is required to be part of the navigation system, mainly for the safety of the public, customers and employees, and also as security for the space transport unit.
Portfolio Identifier: PORT_03 Requirement: The system shall also be able to determine the position of the space transport unit under different weather conditions. Technical: The system shall require access to satellite constellations. The satellite navigation systems should be able to interoperable with older navigation systems. With the combine systems, it can improve the overall navigation availability, because the user will be able to locate moving or stationary object with the same receiver from any of the satellites in any combination. Safety: The tracking system needs to be constantly providing the space transport unit’s position information at all time. Any long length of time of break down in communication could have severe consequences if any incidents may occur. Non-Non-Technical: The ability of changing satellite combinations will allow ground control to keep track of the space transport unit with minimising the time of break down in communication. System Aspect: The tracking system is required to operate under different weather conditions. For a reliable system, it should be part of the navigation system prerequisite, mainly for the safety of the public, customers and employees, and also as security for the space transport unit. Portfolio Identifier: PORT_04 Requirement: The system shall be able to have time synchronisation accuracy with the space vehicle up to 0.1 microseconds. Technical: The navigation system fitted with an atomic clock improves the measured accurate. This allows the system to calculate the exact position with an accuracy of up to 0.1 meter/second. Safety: Allows the space transport unit and the ground station to obtain data as quick as possible, to avoid incidents. Non-Technical: Enabling the system to obtain data in real-time. System Aspect: The navigation system providing data in real-time is required to update its system data and to improve performance.
3. Propulsion System Portfolio Identifier: PORT_05 Requirement: The system shall have at least one main engine. Technical: One main engine can provide enough thrust for the space transport unit to take off and fly safely. Too many engines would put too much weight on the transport unit. With today’s technology one engine is capable of providing enough thrust for a space transport unit. Safety: An engine weighs a lot, and too many engines may weigh the space transport unit down. If the main engine is down, there will be a secondary engine as back up. Non-Technical: Too many engines per transport unit will strain the construction and maintenance budget and the consumption of fuel will also increase. System Aspects: Technical and safety must be considered to make the decision on whether of using how many engines. Portfolio Identifier: PORT_06 Requirement: The engine shall be able to provide at least 95 kN of thrust.
Technical: This is more than enough thrust for injection for the transporter into earth orbit. This amount of thrust is obtainable using today’s rocket engine technology; with current rocket technology able to maintain this level of thrust for well over 200 seconds. Safety: Although much higher levels of thrust are capable from current rocket engine technology, higher levels of thrust will result in G-forces that are not tolerable for human passengers. Non-Technical: The amount of thrust that an engine can produce will determine the price. It is unnecessary to pick an engine and the transport unit will not use the full potential of the engine. System Aspects: All technical, non-technical and safety must be considered to make the decision on how much thrust is the best solution for the space transport unit.
4. Launch System Portfolio Identifier: PORT_07 Requirement: The system shall have at least one runway for take-off and landing. Tech: Aspects of the runway will improve efficiency and enable the Ground terminal to organise launch sequences. Safety: The runway allows for enhanced safety precautions. Emergency vehicles can be close in case they are needed urgently, Patrons and customers can be kept clear of the area. Accurate simulations can be performed in the case of an emergency. Non-tech: A runway is required for a comfortable take off [3]. System Aspects: Portfolio Identifier: PORT_08 Requirement: The runway shall be able to withstand a static weight of 120 tonnes. Tech: The static weight of 120 tones will be able to withstand any space transport unit movements, and prevent damage occurring Safety: The static weight is adequate to be able to move the space transport unit with out causing damage to the space transport unit or the runway. Non-tech: The static weight of 120 tone will allow multiple take-offs and landings on the runway, which will decreases overall costs [3]. System Aspects:
Portfolio Identifier: PORT_09 Requirement: The runway shall be able to withstand an impact of 1.30x3 Nm. in an area of 4 m2. Tech: The required impact pressure for damage not to occur to the runway under full thrust conditions on take off and during the landing of the space transport unit. Safety: An impact resistance of 1.30x3 Nm is more than adequate to safely land the space transport unit. Non-tech: Withstanding an impact of 1.30x3 Nm will allow multiple take-offs and landings on the runway, which will decreases overall costs [2]. System Aspects: Portfolio Identifier: PORT_10 Requirement: The runway shall be treated with skid-resistant material (grooved or PFC) per FAA or ICAO specifications. Tech: This requirement allows for better mobility and increased stopping ability. By using no skid-resistant material the tyres will last longer and save on maintenance Safety: This requirement allows for better mobility and increased stopping ability. Non-tech: Increased comfort, knowing that safety precautions are being implemented [2]. System Aspects: Portfolio Identifier: PORT_11 Requirement: The runway shall be of length no less than 1.5 km. Tech: A runway of 1.5km will be sufficient to be able to take off and land the space transport unit. Non-tech: Runway costs are about $8000000US per 350m. A short runway will reduce costs but a Long runway will give a greater feeling of comfort to passengers. Safety: A runway of length of 2.5km will adequately allow the Space transport unit to abort take-off at any time during the launch sequence and stop before the runway ends. At 1.5km some additional run-off ramps will be required. These run-off ramps may be made of a slightly less grade material [3]. System Aspects:
5. Life Support Portfolio Identifier: PORT _12 Requirement: The system shall maintain temperature control for life support within the range of 8°C to 27°C (64°-81 °F). Technical: Outer space is an extremely cold environment and temperatures will vary drastically in different parts of the space transport unit orbiter. The electronic equipment generates more than enough heat for the ship. The problem is getting rid of the excess heat. So the temperature control system has to carry out two major functions: • Distribute heat where it is needed on the orbiter (mid-fuselage and other sections) so that vital systems do not freeze in the cold of space. • Insulating materials, surface coatings are used to reduce heat loss through the walls of the various components just like your home insulation. • Metallic plates are used to collect heat by direct contact with equipment or conduction The cabin heat exchanger also controls the cabin temperature. It circulates cool water to remove excess heat (cabin air is also used to cool electronic equipment) and transferring heat to warm up the colder section of the space transport unit orbiter. Safety: To our knowledge these temperature controlling systems are safe. An ambient temperature range of 21 to 23oC (70 to 74oF) is optimal for system reliability and operator comfort. While most computer equipment can operate within a rather broad range, a temperature level near 22oC (72oF) is desirable because it is easier to maintain a safe associated relative humidity level at this temperature. Further, this recommended temperature provides an operational buffer in case the environmental support systems are down [5]. Non-Technical: There will be a cost associating to the components that is required, and NASA has already performed their own cost analysis over many uses. System Aspects: It ensures the survival of the passengers on board the shuttle. Portfolio Identifier: PORT_13 Requirement: The space transport unit shall handle no less than 3,000 degrees F (1,650 degrees C) of heat generation (for re-entry to earth). Technical: Space transport unit will require a heat shield, because it will be exposed to extreme heat (up to 2300ûF) during re-entry. Not all parts of the transport unit will experience the extreme heat, some sections may only be exposed to lower temperature, from 600û to 1200ûF, so not all sections requires the same type of heat shield [11]. Safety: Heat shield prevents the space transport unit from burning up during re-entry. Non-Technical: Cost will very depending on the types of material used for the heat shield, different parts will be protected by different types of heat shield. The heat shield is re-usable [8]. System Aspects: It ensures the survival of the passengers on board the shuttle.
Portfolio Identifier: PORT _14 Requirement: The exterior of a space transport unit shall handle no less than 760 millimetres of mercury pressure. Technical: The airlock is normally located inside the mid deck of a spacecraft's pressurised crew cabin. Airlock depressurisation is controllable from the orbiter crew cabin mid deck and from inside the airlock. It is performed by equalising the airlocks and cabin's pressure with equalisation valves mounted on the inner hatch. The airlock is depressurised from inside the airlock by venting the airlock's pressure overboard. [4]. Safety: To our knowledge their have been no safety issues with NASA's air pressure system. Each airlock hatch has dual pressure seals to maintain pressure integrity. One seal is mounted on the airlock hatch and the other on the airlock structure. A leak check quickly disconnect is installed between the hatch and the airlock pressure seals to verify hatch pressure integrity before flight [4]. Non-Technical: NASA has already performed their own cost analysis over many use we will follow their use of components. System Aspects: It ensures the survival of the passengers on board the shuttle. Portfolio Identifier: PORT_15 Requirement: The interior of the system shall maintain an atmospheric pressure of 14.7psi at all times (half of FAA allowance of pressure variation, assuming a linear decrease in pressure with height) [13]. Technical: The cabin is pressurised to 14.7psia, plus or minus 0.2psia, and maintained at an average 80-percent nitrogen and 20-percent oxygen mixture by the air revitalisation system. Oxygen partial pressure is maintained between 2.95 and 3.45psi, with sufficient nitrogen pressure of 11.5psia added to achieve the cabin total pressure of 14.7psia, plus or minus 0.2psia [12]. Safety: Although much higher levels of thrust are capable from today’s spaceship technology. This means that spaceships must have strong walls to keep from blowing up due to the internal pressure. Even a six foot diameter sphere has a pressure of about 122 tons trying to blow it apart due to the atmospheric pressure of 15 psi (pounds per square inch) inside the spaceship (if you simulate the atmospheric pressure of the earth [6].) This level of precautions is safe for the structural integrity of the spacecraft, and will also allow all other systems to operate correctly. Non-Technical: Cost: Because NASA has already performed their own cost analysis over many use we will follow their use of components atmosphere. System Aspects: It ensures the survival of the passengers on board the shuttle.
6. Maintenance Portfolio Identifier: PORT_16 Requirement: Any hazardous materials used in design of the Space Transport Unit shall be separated at unit retirement as described by the Basel Convention on the Control of Trans-boundary Movements of Hazardous Wastes and their Disposal. Technical: Hazardous material used to design Space Transport Unit could be solid, liquid or gas that can harm humans or other living organisms due to being radioactive, flammable, and explosive etc. The hazardous material should be stored in a closed container under a dry-insert blanket. The storage area should be ventilated and the room temperature kept at 4ºC. The hazardous material requires separate unit retirement, to keep it safe. Safety: To ensure the safety of the person who handles the hazardous material, that person has to wear the protective clothing to protect him or herself from the hazardous materials. Special protective clothing has been treated to offend hazardous chemical, biological or radioactive materials. We have to ensure that, a First–Aid kit is provided near the storage area. Non-Technical: The hazardous materials could be solid, liquid or gas; therefore we have to keep the container safe. We have to avoid exposing the container to the atmosphere, because those hazardous materials could diffuse through air, which will pollute the air quality and also the environment. System Aspect: The hazardous materials are very dangerous, which will cause serious harm to human health and might lead to death. Therefore, we have to take serious action in separating the hazardous materials at the unit retirement. Portfolio Identifier: PORT_17 Requirement: Any hazardous materials used in design of the Space Transport Unit shall be disposed of at unit retirement as described by the Basel Convention on the Control of Trans-boundary Movements of Hazardous Wastes and their Disposal. Technical: Hazardous materials are very dangerous, which can harm human and living organisms. The disposal of hazardous waste must follow the Basel Convention. The Basel Convention was designed to reduce the movements of hazardous material between nations, and specifically to prevent dumping of hazardous waste from developed to less developed countries (LDC). Safety: The hazardous waste are dangerous objects, therefore we have to be very careful while disposing them. The disposal process needs to follow the way which is stated in the government and local environmental control regulation. Non-technical: To dispose the hazardous waste, special disposal company is needed to dispose the hazardous waste. The disposal company must be approved by the government. System Aspect: It is important to dispose the hazardous waste by using the correct method and must be in accordance with the government and local environmental control regulations.
Portfolio Identifier: PORT_18 Requirement: Any hazardous materials used in design of the ground facilities shall be separated at retirement as described by the Basel Convention on the Control of Trans-boundary Movements of Hazardous Wastes and their Disposal. Technical: Hazardous material used in design ground facilities maybe solid, liquid or gas which can seriously harm humans or other living organisms. The hazardous material should be stored in a closed steel container under a dry-insert blanket and maintain the room temperature at 4o C. Safety: To ensure the safety of the person who handles the hazardous material, that person has to wear the protective clothing to protect him or herself from the hazardous materials. As describe before, the protective clothing is very powerful which can protect he/she from getting affected. We have to ensure the First-Aid kit is around the storage area Non-Technical: The hazardous materials could be solid, liquid or gas; therefore we have to keep the container safe. We have to avoid exposing the container to the atmosphere, because those hazardous materials could diffuse through air, which will pollute the air quality and also the environment. System Aspect: The hazardous materials are very dangerous, which will cause serious harm to human health and might lead to death. Therefore, we have to take serious action in separating the hazardous materials at the unit retirement.
7. Storage Portfolio Identifier: PORT_19 Requirement: The Space Transport Unit Hanger shall be enclosed within the dimensions 50m x 200m x 15m. Priority: High Technical: The dimensions 150mx200mx15m for the transport unit’s hanger were chosen because the hanger has to enclose 5 or more transport units and also enough storage space for the associated maintenance equipment. Estimated floor space needed to house each transport unit and its equipment is 25mx35m. Non-Technical: The transport unit hanger was chosen to be a strong, secure, fully enclosed structure, but also be well ventilated. A fully enclosed hanger will help with monitored security and will provide protection from outside elements such as wind, rain etc. The transport unit hanger would cost somewhere between $250,000 and $300,000 depending on the quality of the construction material. Safety: For the hanger to meet safety requirements it will have to be well ventilated, have emergency exits, electrical safety equipment etc. System Aspects: The space transport unit’s hanger provides protection and security to the transport unit while not in operation.
Portfolio Identifier: PORT_20 Requirement: The hanger shall provide security surveillance 24hours a day with restricted access and security surveillance for all Space Transporter Units. Technical: To visually monitor the surrounding areas, cameras will be attached to the outside wall of the hanger at 50m intervals. Security cameras will be capable of surveillance of 24 hours a day in all weather conditions. Non-Technical: To combat security problems entrance to the transport hanger will be restricted to authorised personnel. All personnel entering the hanger will require a security card, for further security, cameras will be installed at the hanger and will be monitored 24 hours each day at the security office. Safety: Security cameras will be used to keep the workers and equipment safe from saboteurs and thieves. Safety within in the hanger will be achieved by keeping the building secure and free from unauthorised personnel. System Aspects: 24 hour Surveillance provides security to the property of SeaLink. Portfolio Identifier: PORT_21 Requirement: The ground terminal shall provide storage space for ground terminal maintenance equipment during all working hours Technical: Ground terminal maintenance storage area will have a secure area large enough to store all the required maintenance equipment. Storage area will be subdivided for the storage of different materials e.g. hazardous, non-hazardous, flammable etc. Non-Technical: The ground terminal storage area will be always accessible to authorised personnel. Safety: The ground terminal storage area will be regularly maintained (e.g. tidy shelves, floor cleaned etc.) to reduce the likelihood of accidents. Access to hazardous and flammable materials will be highly restricted and will require special access. System Aspect: Storage facility for maintenance equipment provides security to equipments, so any unauthorised personnel cannot get access to the equipment. It also provides a safe working place. Portfolio Identifier: PORT_22 Requirement: The Ground Terminal Maintenance Storage shall be 100m x 100m x 10m. Technical: The dimensions 100mx100mx10m for the ground terminal storage were chosen because the storage area has to enclose maintenance equipment to service all ground terminal facilities. Non-Technical: The ground terminal storage area was chosen to be a secure, fully enclosed structure with some ventilated areas. A fully enclosed storage area provides security and protection for equipment from the outside elements such as wind, rain etc. The ground terminal storage area will cost somewhere between $100,000 and $150,000 depending on the quality of the construction material. Safety: For the ground terminal storage area to meet safety requirements it will have to be well ventilated in the areas containing hazardous and flammable materials, have easily accessible emergency exits, electrical safety equipment etc. System Aspect: The dimensions of the maintenance storage, provides enough space to store equipments and ease of access to equipment inside the storage area.
Portfolio Identifier: PORT_23 Requirement: The Ground Terminal shall provide storage space for Space Transport Unit maintenance equipment during all working hours. Technical: It is necessary for the maintenance equipment to be stored in the appropriate conditions. The equipment can be damaged if stored in conditions that are outside its working limits. All storage space for maintenance equipment is stored at 22 Celsius unless the equipment states otherwise. Non-Technical: The maintenance storage space will be required to be located close to the maintenance area to accommodate quick access during all working hours for maintenance repairs. Safety: The maintenance storage space will be accessed regularly, it is necessary for there to be enough space for all storage equipment during all hours. The storage space must be free from debris and have enough lighting for persons to see the storage space easily. For safety standards there is an evacuation route indicating all safety exits. System Aspects: Portfolio Identifier: PORT_24 Requirement: The Space Transport Unit Maintenance Storage shall be 100m x 100m x 10m. Technical: The maintenance storage space is to be 100m x 100m x 10m this allows for the storage for all space plane maintenance equipment. The space transport unit maintenance storage outer casing is manufactured from a double skin insulated sheet to reduce condensation and temperature change in the storage space. Non-Technical: The storage space dimensions of 100m x 100m x 10m will require 14000m 2 of double skin insulated roof/wall sheeting; this is the most cost effective solution when compared to other insulating roof/wall sheeting. Safety: The storage space is engineered to 100m x 100m x 10m to allow for a safe structure which will be resistant to wind, rain, heat and cold. System Aspects: The dimensions and the materials of the space transport unit maintenance storage are made from materials to meet all requirements and the dimensions of the storage unit which will allow for all maintenance equipment to be stored safely.
Portfolio Identifier: PORT_25 Requirement: The Ground Terminal shall have underground fuel storage. Technical: The fuel storage is stored underground at a constant temperature. The temperature will meet the fuel storage temperature. Fuel storage is to facilitate for 6000000ltr of fuel. Non-Technical: The fuel storage is kept underground rather than above ground for space saving. Underground storage is used rather than above ground storage because it is easier to maintain a constant temperature underground rather than above ground, this will reduce the risks of combustion due to the high temperatures in South Australia. Safety: The underground storage space has many advantages in safety. If the storage space is stored above ground it would be susceptible to many safety factors. This includes terrorists, temperature control and security access. System Aspects: Having an underground fuel storage would impact on a larger financial cost than to have fuel storage above ground, underground fuel storage is justified mainly by the safety aspects involved. If the safety of fuel storage is compromised it could result in a possible destruction of the whole ground base. Portfolio Identifier: PORT_26 Requirement: The fuel storage shall be at least 1.5km away from surrounding buildings. Technical: From a technical point of view it is not feasible to have fuel storage 1.5km away. The fuel storage should be close to the hanger. Non-Technical: The fuel storage is located a least 1.5km away from surrounding buildings to facilitate customer satisfaction; it is not pleasurable to know that the customer is situated on top of a large amount of highly flammable fuel. Therefore the fuel storage is located at a distance at least 1.5km from surrounding buildings. Safety: There is a large safety aspect when considering the location of the fuel storage, it is located 1.5km away from surrounding buildings in the case of an accident or explosion of the fuel storage, this distance will minimise any damage to surrounding buildings and personnel. System Aspects: The fuel storage space is located 1.5km away from surrounding buildings mainly from a safety prospective; technically the fuel should be located close to the hanger to make maintenance fast and efficient. Portfolio Identifier: PORT_27 Requirement: The fuel storage shall store 6000000 litres of fuel. Technical: The fuel storage is to have enough fuel to last twenty flights as required by the requirement GT_SC11, this equates to 6000000litres of fuel. Non-Technical: This allows for twenty flights due to the large number of space transport units on mission. Safety: It is not desirable to hold 6000000litres of fuel due to the huge safety concerns. System Aspects: It is not desirable to hold 6000000litres of fuel, however it is specified that the there must be enough fuel for at least 20 flights. This is due to the high demand for space travel.
8. Service Portfolio Identifier: PORT_28 Requirement: All pre-launch maintenance tools shall be stored in the Ground Terminal Storage hangar Technical: As described previously the storage hangar is 100m x 100m x 10m, this technically provides the system with a large enough area to store all the required equipment. This includes pre-launch maintenance tools which will be located in a particular section of the hangar. Safety: Obviously the safest workplace is a clean workplace, in the case of storage for the pre-launch maintenance tools the use of a storage hangar to house any equipment required is vital. Safety for maintenance staff, flight staff and also the customer must be considered and hence is why all tools and equipment must be kept in a secure location. Non-Technical: The storage hangar will be required to be located close to the launch area to accommodate the quick access needed to make any pre-launch maintenance as the tools will be within the hangar at all times. System Aspects: The system as a whole will operate more efficiently if the prelaunch maintenance tools are stored in a secure location which is easily accessible. It therefore is clear that the pre-launch tools should be kept in the Ground Terminal storage hangar. Portfolio Identifier: PORT_29 Requirement: All basic level maintenance equipment shall be stored in the Ground Terminal Storage hangar Technical: The basic maintenance tools will be located within the Ground Terminal storage hangar in a separate location designated for them. Safety: To ensure the safety of the customers, the basic level maintenance tools will be stored separately from other tools so that maintenance can be completed without the hassle of other maintenance staff using the required tools.

Advanced level repairs may include things such as major propulsion system, or major navigation and flight system repairs. System Aspects: As a large scale operation where passengers’ lives will be put at risk during every flight, the maintenance of the space transport units is vital for a successful operation. The advanced level maintenance equipment will have to be readily accessible in any situation and so it is of high importance that it is located in a separate zone within the Ground Terminal storage hangar.
Portfolio Identifier: PORT_31 Requirement: All pre-launch maintenance equipment shall be located within the Ground Terminal boundaries Technical: The Ground Terminal boundaries will accommodate all of the Systems buildings, space transport units and relevant facilities. This includes the maintenance equipment which will always be stored within the boundaries of the Ground Terminal to ensure access to it can be made at any time. Safety: The access to maintenance equipment is very important to the systems success. The safety of customers and crew members depends on the availability of the safety equipment. To ensure that any problem threatening the safety of customers is eliminated, all maintenance equipment will be stored at the Ground terminal at all times. Non-Technical: For ease of maintenance and to reduce time taken all tools and equipment required for maintenance tasks are kept in storage at the ground terminal. System Aspects: For the system as a whole to operate at full efficiency the best solution is to keep everything which may be required for use on the Ground terminal or Space transport unit to be housed permanently within the Ground Terminal boundaries.

Conclusion: Serious and detailed consideration was first given to the possibility of space being opened up to trips by the general public three decades ago, and some initial attempts to do so around a decade ago, mainly in Russia and the United States. In recent years, professional space tourism studies have been conducted in the United Kingdom, Germany and, especially, Japan and China. In the U.S., technological progress has been pronounced and it has be proven to the general public that it is possible for astronaut travel to and from low Earth orbit safely. NASA and the commercial space industry now have new and promising space transportation development programs underway; especially the space plane X-33 and X-34 programs, and some related development programs [1]. From the feasibility study conducted by the team in this report, a space plane is shown to be the most feasible technology considered for the proposed joyride to space. Today, tourism trips are limited to surface travel or low-altitude flight. Opportunities to experience space-like conditions are limited to "zero-gravity" trips in aircraft and simulations. Even so, over 10 million people each year visit a space museum, a space camp, a rocket launch-recovery site or government space R&D centres -- a business with estimated revenue of $1 billion per year [1]. This business could be expanded, especially if the general public could see programs underway that specifically offer the promise of trips to/from space becoming available early in the next decade. Its expansion would attract entrepreneurs and investment attention to in-space business possibilities and it is a venture that Australia should consider. For Australia’s Space ambitions, Matthew King, author of the journal “The Lowdown”, address the topic of Australian Space development in focus. In this report, he states that Australia should launch a national campaign to be involved in the push to make space travel a commercial reality. If a few Russian or Chinese space engineers could be hired for their experience sharing, this could prove to be an inexpensive option worth pursuing. Space development is also perceived as an economic multiplier as every dollar spent on space percolates through the economy, creating growth and wealth. Space travel is still considered a relatively high risk proposition, due to the cuttingedge technology relied upon. To promote the space tourism industry, operators need to ensure that both the transportation and destination are safe, accessible, and comfortable enough to provide tourists with a positive experience. If travelling patrons get hurt or sick, or if they just have an unpleasant experience, word of mouth will quickly discourage other potential customers. This may be especially true when space tours are accessible only to the rich and famous, whose descriptions of their experiences (favourable or unfavourable) will colourfully capture the public's attention. The system utilising space planes, as described in this document, addresses all of these issues and is sure to be a commercial success for our client, SeaLink.

1.0. Introduction Travelling to space is a complicated and difficult process because there are so many problems to solve and obstacles to overcome. Some of these problems to overcome when travelling to and from space shown below greatly affect the path we follow in order to achieve our objectives: • • • • • •
The vacuum of space Heat management problems Re-entry into Earth’s atmosphere Orbital mechanics Micrometeorites and space debris Cosmic and solar radiation
The following is a list of the possible transportation vehicles based on today’s available technologies, as well as some technologies that require periods of development. A brief list is given here, with short descriptions. The list is categorised into the following sections: • Conventional Vehicles • Alternate Vehicle Conventional Vehicles Rockets o VTOL Orbital Booster Conventional vertical take-off and vertical landing rocket engine booster with crew compartment on top of the rocket stack. Similar to boosters used in the Apollo, Mercury, and Gemini programs, and currently in the Soyuz program. This configuration is capable of achieving full orbital insertion with significant G-forces being felt by the passengers. The picture below in figure 3.6 is the Soyuz V rocket from Russia

o VTHL Orbital Configuration Conventional vertical take-off and horizontal landing rocket engine powered system similar to the dual-booster arrangement of the American shuttle orbiters. This configuration is capable of achieving a stable orbital insertion, as opposed to a sub-orbital trajectory. o VTHL Sub-Orbital Configuration Vertical take-off and horizontal landing rocket engine powered system. This vertical take off vehicle is designed only for sub-orbital flight, and hence as we have discussed has simplified requirements with regard to heat shielding, propulsion, and overall cost. Space Plane The Space Plane is a HTOL1 configuration incorporating dual propulsion systems. Jet engines are used to bring the craft to ceiling height, at which point a rocket engine is ignited, boosting the craft out of the atmosphere. Current technology allows for only sub-orbital flights. That is, the booster can only provide enough energy to push the craft outside the atmosphere for a matter of minutes before it 1

falls back to Earth. This restriction is related to the amount of fuel on board, as well as the weight of the craft. The picture below is the Space-Plane X33 which is based on horizontal HTOL take-off.

2STO Sub-Orbital Vehicle Two-stage to sub-orbit vehicle. Scaled Composite’s SpaceShipOne is an example of such a system. The space vehicle is attached to an advanced jet aircraft, capable of climbing to ceiling height with the vehicle attached. At this height, the space vehicle is released, and its own propulsion system is activated for a duration long enough to allow the craft to climb above 100km. It then follows a ballistic trajectory, incorporating aero-braking to facilitate a horizontal landing on a normal landing strip. The 2STO configuration has the advantage of requiring less fuel and weight onboard the space vehicle, as it ‘hitches a ride’ with the jet aircraft to ceiling height.
55
Alternative Vehicles Hybrid Jetpacks The use of jetpacks is proposed as a dual-craft configuration where passengers in Jetpacks are released from a Jet plane cruising at ceiling height. Rocket engines fitted to each jetpack then boost the passengers into a suborbital trajectory. The small size and weight reduces the requirements placed upon the boost rocket engine. This vehicle requires significant technological development in the form of initial investment to be successful. The inclusion of this vehicle type is for discussion purposes only, as it has a relatively low predicted viability. Space Cable Car The cable car is a novel technology that is not yet fully functional. Considerable initial investment would be required in order to utilise this technology in a space tourism application. It involves a cable link between the surface of the Earth and a satellite in geostationary orbit. The cable needs to have extreme structural integrity to withstand the large forces that are placed upon it. Passengers and cargo board a passenger transport on the Earth’s surface and the transport is then lifted into space along the cable.
1.2 Analysis Criteria for the Proposals Performance Measure: Safety Relative Importance: 1 This performance measure is defined as the public’s perception of the safety of a particular transportation method. Since the space excursion itself carries the same risks in the case of any space transportation vehicle, this performance measure is mostly effected by the launch and landing characteristics of the vehicle. Conventional systems such as vertical take-off and horizontal take-off2 craft score well due to the practiced nature of the technology. Since safety is a subjective measure that depends on the customer’s perception, the safety rank is simply assigned as a number from 1 to 9, with 1 indicating a less safe perception and 9 indicating the safest perception. Performance Measure: Flight Enjoyment Relative Importance: 2 Enjoyment is an important performance characteristic as on of the customer’s needs is for a ‘joyride’ into space, and hence the flight needs to be as enjoyable as possible. The nature of space flight dictates that the craft needs to be accelerated away from the Earth, perform on-orbit operations, and then return to the Earth. The forces exerted on the passengers during the return trip are proportional to the initial force that is exerted on the passengers during their acceleration to space. Therefore, the enjoyment index is calculated as a combination of the relative ascent time spent under acceleration, and the force exerted on the passengers during that acceleration. Flight enjoyment index = Ascent time under acceleration / Average force exerted on passengers during acceleration
Performance Measure: On-Orbit Enjoyment Relative Importance: 3 The second part of determining the enjoyment of the flight is the state of facilities available during on-orbit operations. This is related to the size of the transportation vehicle, which determines the amount of space available for such facilities as windows. Small capsule-like craft score poorly, while larger airline-style variants score well. It is also related to the maximum amount of people that the vehicle is capable of supporting at one time. 2
VTOL = Vertical take-off and Vertical Landing, HOTOL = horizontal take-off and horizontal landing
56
On-orbit enjoyment index = Size of crew compartment of vehicle / Maximum number of passengers that are to be accommodated in that compartment
Performance Measure: Initial Cost Relative Importance: 4 The predicted initial cost is the cost in $AUD required for the complete design and development of the transportation vehicle. This includes engineering design, review, prototype construction, subsystem testing, and final construction and testing.
Performance Measure: Time Provided In Space Relative Importance: 5 The time duration of the flight will determine if the passengers will experience the symptoms of being in space. It is related to the enjoyment measure, as higher levels of thrust will result in greater discomfort for the passengers, but will allow them to experience space for a longer period of time. This relationship saturates once sufficient energy to achieve orbital insertion has been achieved. Performance Measure: Cost to the End-User Relative Importance: 6 The predicted cost in $AUD per seat per passenger for one trip into space. The pioneering flights of Tito, Shuttleworth and Olsen came with a price tag of USD $20 million dollars, however current plans for sub orbital space trips come with predicted costs as low as $USD 20,000. Performance Measure: Operational Cost Relative Importance: 7 This is the predicted cost to SeaLink Inc. for conducting one mission. It includes the cost of fuel, post flight repairs, and other vehicle-specific attributes. Performance Measure: Operational Lifetime Relative Importance: 8 This measure incorporates the predicted MTTF and the entire operational lifetime of the vehicle from the time of commissioning to decommissioning.

1.3 Analysis of Proposals The proposals introduced in section 1.1 would be analysed in detail with the analysis criteria specified in section 1.2
1.3.1 VTOL Orbital Booster Rocket Description: VTOL systems are currently implemented in the Russian Soyuz class spacecraft with excellent success. The Mercury, Gemini, and Apollo missions all used VTOL class launch vehicles. Since 1966 the most successful VTOL booster, Soyuz, has launched 750 times with a success rate of more than 97% [17]. Propulsion Type Score The VTOL system utilises a standard rocket engine possessing enough thrust to put the cargo into Earth orbit. The propulsion system consists of a liquid fuel that is ignited by an oxidiser, subsequently initiating a controlled explosion that releases enough energy to push the craft into orbit. Although such technologies are well developed in today’s space industry, the incredibly dangerous nature of the propellants is a severe safety concern. For this reason, we assign the VTOL rocket a Propulsion system score of 1. Launch Fuel Score The amount of fuel in a VTOL configuration at launch is the most out of any of the proposed vehicle types. The Soyuz rocket requires, on average, 160,000 kg of highly volatile kerosene and liquid oxygen propellant [20]. For this reason, we assign this launch vehicle with a fuel score of 0. Mission Goal Score The mission goal of an orbital VTOL configuration is Earth orbit. This makes the flight less safe as compared to a suborbital excursion as the spacecraft is subject to higher stress levels, as well as the challenge of re-entry [10]. For this reason we assign a mission goal score of zero. Physical Protection Score The physical protection provided by a VTOL configuration is relatively good. A capsule can be used to safely accommodate the passengers, as well as provide the required shielding to protect from cosmic radiation. We therefore assign the VTOL configuration with a protection score of 2 The overall safety score for the orbital VTOL vehicle is 2+0+0+1 = 3 Entertainment factor (Figures Based on the Russian Soyuz Booster [17]) Ascent Time under Acceleration = 500s Ascent Thrust = 4034 kN Launch Weight = 289,467 Kg Flight enjoyment Measure = 500s * (4034 kN / 289, 467 kg) = 6.967 Time in Space for VTOL Orbital Booster: 40 hours (2400 minutes) Flight Enjoyment Measure = 6.97 Space Experience Measure = 2400 / 6.97 = 344.3 Cost factor As of 1999, the mission cost for the Soyuz spacecraft launching aboard the R-7 VTOL booster was approximately AUD $53.2 million dollars, and hence the cost per passenger would be some fraction of this number, depending on the number of passengers aboard. If we disregard profit margins, a generalised VTOL 58
launch vehicle carrying 50 passengers at approximately AUD $50 million dollars per launch would deliver a cost of approximately AUD $1 million dollars to the end-user.
1.3.2 VTHL Orbital Vehicle The VTHL configuration has been solely applied in the American space shuttle orbiter. Designed to launch like a rocket and land like an aircraft, the Shuttle has flown 114 missions with a 98.25% success rate [18]. Since its inception in 1981, several possible flaws have been identified in the VTHL configuration, including the possibility of spacecraft damage during ascent due to debris from the booster rockets. Propulsion System Score The launch requirements for a VTHL configuration typically involve the use of a space orbiter craft attached to a booster system. In the case of the American space shuttle orbiter, the spacecraft is attached to an external fuel tank, which is in turn attached to two rocket boosters on either side of the tank. Also, the craft’s heat shield (an essential part of an orbital flight) is facing the boosters during flight, allowing any debris coming off the boosters to impact the heat shield, and possibly cause damage. Such damage was found to be the cause of the Columbia disaster in 2003 [19]. In review, modification of the orientation and protective measures of this vehicle type is possible, making this configuration highly useable with the appropriate safety modifications. However, the propulsion system still shares several dangerous characteristics with the VTOL launch vehicle. Hence, we assign a score of 1 here. Launch Fuel Score The launch fuel requirements for a VTHL configuration are the same as that for a VTOL vehicle. The vehicle must be fully fuelled at launch, with an average of 700,000 kg of highly volatile liquid hydrogen and liquid oxygen propellants for the American space shuttle [19]. The potential danger of these propellants at launch is exemplified by the Challenger disaster. Hence we assign a score of 0 here. Mission Goal Score The mission goal for a VTHL configuration is the same as that for a VTOL vehicle, and requires complete orbital insertion. Hence we assign a score of 0 here. Physical Protection Score The physical protection requirements for a VTHL configuration are the same as that for a VTOL vehicle, hence we assign a score of 2 here. The overall safety score for the orbital VTHL vehicle is 2+0+0+1 = 3 Entertainment factor Time in Space: 2400 minutes Flight Enjoyment Measure = 5.408 Space Experience Measure = 2400 / 5.408 = 443.7 Cost factor In a space tourism application with 50 passengers, a similar VTHL vehicle would be loaded with 50 passengers weighing approximately 100kg each, which is a total payload mass of 5000kg, one fifth of the standard shuttle launch mass. The launching cost would therefore be less by only a factor of approximately one tenth ($AUD 1 billion dollars), as less rocket fuel is needed, but more consumables such as oxygen are required to sustain the passengers and crew. With 50 passengers, and disregarding profit margins, the cost per passenger would therefore be approximately AUD $20 million dollars.
59
1.3.3 VTHL Sub Orbital Vehicle Propulsion System Score The launch requirements for a VTHL Sub Orbital configuration are the same as that for VTOL and orbital VTHL configurations, hence we assign a score of 1 here. Launch Fuel Score Since this vehicle needs only attain the required speed to push itself momentarily into space, the amount of fuel required at launch is greatly reduced. A comparison of the energy required for an orbital and suborbital flight reveals that approximately 32 times less energy is required to accomplish the latter [10]. However, since the VTHL configuration is using rocket propulsion throughout the entire flight, it will still require more fuel than a Space Plane or 2STO vehicle. Hence, we assign a score of 1 here. Mission Goal Score As discussed earlier, a suborbital mission goal results in a much safer flight due to simplified requirements in terms of speed, force, and re-entry. Hence we assign a score of 2 here. Physical Protection Score The physical protection requirements for a VTHL Sub Orbital configuration are the same as that for a VTOL and VTHL orbital vehicle, hence we assign a score of 2 here. The overall safety score for the VTHL suborbital vehicle is 1+1+2+2 = 6 Entertainment factor (Figures Based on the American Shuttle Orbiter [28]) Ascent Acceleration Time = 530 s Ascent Thrust = 34,000kN (This thrust is for the Space Shuttle with a 25,000 Kg payload delivery to LEO. Actual space tourism application with approximately 50 persons at 100Kg each = 5000 kg. Approximate thrust required = 10,000kN) Launch Weight = 5000 kg payload + 1,000,000 kg Weight of shuttle, boosters, and external fuel tank = 980,000 kg. Less fuel required for lighter payload is taken into consideration. Flight Enjoyment Measure = 530s * (10,000 kN / 980,000 kg) = 5.408 Time in Space = 5 minutes Flight Enjoyment Measure = 1.431 Space Experience Measure = 5 / 1.431 = 3.49 Cost factor Manufacturers of the ‘Ascender’ sub orbital booster are expecting to offer flights on their VTHL winged-booster rocket at a price of AUD $6500. It is a reasonable assumption that this price is indicative of most current VTHL sub orbital ventures.
1.3.4 Space Plane Propulsion System Score A space plane employs 2 propulsion systems. First, jet engines bring the craft to ceiling height, and then rocket engines ignite to push the craft into space. The fact that characteristically dangerous rocket propulsion is being used for only half the flight makes this approach the safest of all those we have considered. Hence, we assign a score of 2 here. 60
Launch Fuel Score Since rocket propulsion is only being used for half the journey, a relatively small amount of hazardous rocket fuel needs to be stored on board. However, jet engine fuel is still required in order to allow the Space Plane to reach ceiling height, and hence this takes away very slightly from the benefits created by the lack of rocket fuel. Hence, we assign a score of 1.5 here Mission Goal Score As is the case for the VTHL sub-orbital vehicle, the sub-orbital mission goal allows for a less complex and safer space flight. Hence, we assign a score of 2 here. 5.1.4.4 Physical Protection The physical protection requirements for a Space Plane configuration are the same as that for VTOL, and VTHL orbital vehicles, hence we assign a score of 2 here. The overall safety score for the Space Plane is 2+1.5+2+2 = 7.5 Entertainment factor Ascent Time Under Acceleration = 97s Ascent Thrust = 84.1 kN Launch Mass = 5,700 kg Flight Enjoyment Measure = (84.1 kN / 5,700 kg) * 97s = 1.4311 Time in Space = 3.5 minutes Flight Enjoyment Measure = 1.388 Space Experience Measure = 3.5 / 1.388 = 2.521 [21] 2005, ‘Suborbital Reusable Launch Vehicles and Emerging Markets’ Federal Aviation Administration and the Office of Commercial Space Transportation Cost factor Rocketplane Ltd. is planning on offering their sub orbital service aboard the Rocketplane by January 2007. The initial price per passenger for this sub orbital flight is expected to be approximately AUD $129,350 [21]. It is a reasonable assumption that this price is indicative of most current Space Plane ventures.
1.3.5 2STSO Sub-Orbital Vehicle Propulsion System Score A 2-stage to sub-orbit vehicle has similar propulsion system characteristics as the previously discussed Space Plane. In a 2STSO vehicle, the space transport unit is in a parasitic configuration, attached to a jet aircraft. 2 propulsion systems are used, and hence the safety of the approach is relatively good as a rocket engine is only being used for half the flight. The propulsion system for a 2STSO vehicle differs from a Space Plane in that the rocket engine needs only push a fraction of the weight of the combined aircraft. This means that, in comparison to the Space Plane, only a fraction of rocket propellant needs to be used to accelerate a 2STSO space vehicle into orbit, as it has far less weight than a Space Plane vehicle. Hence, we assign a score of 2 here. Launch Fuel Score As stated above, the amount of rocket fuel required by a 2STSO vehicle is considerably less than that which is required by a space plane. This increases the safety aspect of the 2STSO approach slightly. Hence, we assign a score of 2 here. 61
Mission Goal Score The sub-orbital mission goal allows for a less complex and safer space flight. Hence, we assign a score of 2 here. Physical Protection Score The physical protection requirements for 2STSO configuration are the same as that for VTOL, and VTHL orbital vehicles, hence we assign a score of 2 here. The overall safety score for the 2STSO vehicle is 2+2+2+2 = 8 Entertainment factor Ascent time under acceleration: 87s Ascent Thrust: 74kN Vehicle Weight: 3600 kg Flight Enjoyment Measure = (74 kN / 3600 kg) * 87s = 1.788 From the previous sub-orbital flights of SpaceShipOne, the average time spent in space is approximately 3.5 minutes Time in Space = 3.5 minutes Flight Enjoyment Measure = 1.788 Space Experience Measure = 1.957 Cost As we have discussed, Sir Richard Branson is entering into a venture in partnership with Scaled Composites to produce a SpaceShipOne variant for the purposes of conducting commercial sub orbital flights by 2007. The price per passenger for these initial flights is expected to be AUD $273,000 [27].
1.3.6 Hybrid Jetpacks Propulsion System Score This vehicle would use a combination rocket engine and reaction control thruster system (RCS) in order to perform a successful sub-orbital flight. A rocket engine would be required to boost the vehicle into space, and the RCS would be required for performing manoeuvres while in space. The propulsion system required here would have a high element of danger, as a fuel source of some description would be very close to the passenger. Also, it is reasonable to assume that that the rocket nozzle would be very close to the passenger also. The small size of the jet pack would necessitate the use of a relatively small rocket motor cone, and in essence would require the miniaturisation of most modern rocketry components. Even if this was completed within project schedule requirements, the proximity of the passenger to both the fuel source and the rocket nozzle makes this approach highly dangerous. Hence, we assign a score of 0 here. Launch Fuel Score When released from the aerial ‘mother ship’, the amount of fuel required to boost into orbit is very hard to quantify. Since this application of Jet Pack technology has not been previously considered, there is no reference material that can aid in this discussion. One can deduce that the relatively light weight of the vehicle, coupled with the limited space available for fuel storage, would allow us to conclude that there would be a relatively small amount of fuel required at launch for this configuration. Hence, we assign a score of 1 here. Mission Goal Score The sub-orbital mission goal allows for a less complex and safer space flight. Hence, we assign a score of 2 here. 62
Physical Protection Score This vehicle provides the least amount of physical protection from all the others we have considered. In a jetpack system, the passenger is exposed to micrometeorites and other space debris, as well as to cosmic radiation such as the Van Allen radiation belts. Since a considerable layer of shielding is required to protect against this radiation, this would considerably increase the weight and size of a jetpack system. Even with spacecraft-like shielding, there are limited provisions for the protection of vital life support systems and avionics systems. Hence, we assign a score of 0 here. The overall safety score for the hybrid jetpack vehicle is 0+1+2+0 = 3 Entertainment factor Ascent time under acceleration: 130s (similar to other sub orbital missions) Ascent Thrust = 3.5 kN (300 Kg mass overcoming the 9.81 m.s-2 acceleration of gravity) Vehicle Weight = 300 kg Flight Enjoyment Measure = (2.9 kN / 300 kg) * 130s = 1.51 Time in Space = 3.5 minutes Flight Enjoyment Measure = 1.51 Space Experience Measure = 3.5 minutes / 1.51 = 2.317 Cost If we continue with our two assumptions, firstly the AUD $1billion dollar development cost, and secondly that the Jetpack design will become a miniature 2STSO vehicle, we can calculate that the cost per mission will be similar to the 2STSO cost presented above. In addition to a portion of the development cost (which, we assume, will be passes on to the end-user), the total end-user cost will be (very) approximately AUD $300,000. 1.3.7 Space Cable Car Propulsion System Score The Cable car would utilise a revolutionary drive system to pull the car into orbit. A possible cable car configuration discussed in SPACEMART in 2001 described a Maglev system whereby the car is pushed into orbit by an advanced magnetic lift system. The propulsion system may utilise rocket technology, but on a much lower scale than the previously discussed vehicles. Hence we assign a score of 1.5 here. Launch Fuel Score Since the cable car does not predominantly use rocket technology to lift itself into space, the amount of fuel required will be small. Some fuel may be required for rocket engines that provide an initial momentary lift force, and this amount of fuel will be very small in comparison to the other vehicles we have discussed. Hence, we assign a score of 2 here. Mission Goal Score The mission goal for a Space Cable Car vehicle is the same as that for a VTOL and VTHL vehicles, requiring complete orbital insertion. Hence we assign a score of 0 here. Physical Protection Score Passengers are relatively well protected inside the car, as it can be large enough to afford spacecraft-like shielding and other important physical protection means. The cable itself is highly vulnerable to damage that may be caused through likely collisions with space junk and other objects. A tear in the cable would be a catastrophic event, as the cable is the means by which the car is secured, and if the cable broke there is a possibility that the car would be lost. Hence, we assign a score of 0.5 here. The overall safety score for the Space Cable Car = 1.5+2+0+0.5 = 5 63
Entertainment factor Vehicle Weight: 20,000 kg Flight Enjoyment Measure = (196kN / 20000kg)*7200s = 70.56 Time in Space = 2400s Flight Enjoyment Measure = 70.56 Space Experience Measure = 34.013 Cost Below are the approximate running costs for the space elevator proposed by Dr. Brad Edwards [24]: Annual Operating Budget per year in US$M Climbers 0.2 - 2 each Tracking system 10 Anchor station 10 Administration 10 Anchor maintenance 5 Laser maintenance 20 Other 30 TOTAL (50 launches)

The data presented quotes a USD $135 million dollars (AUD $175.5 million dollars) annual expenditure for a 50-mission year, resulting in a cost of $AUD 3.5million dollars per mission. Disregarding profit margins, and assuming a 50 passenger crew, this would result in a cost per passenger of approximately AUD $70,000.

Assigning Value Curves Value curves allow us to define the relationship between an increase in the quality of a certain performance measure and the amount of value added to the system. The shape of each of the value curves defines a different relationship between these two quantities, and the equations describing the graphs can be used to calculate an adjusted ranking. Vehicle Safety As vehicle safety is decreased, the reliability and marketability of the system is decreased. Therefore, the system value will drop exponentially, and hence the increasing RTS curve is chose, as shown below.
Increasing RTS [30]: Calculated equation = v(x) = -x0.5+1 The values for vehicle safety were computed and it is represented in table 6 below.

Table 6: Rankings and Value Curves
This performance measure has similar behaviours to the previous measure, in that a decrease in the customer’s perception of vehicle safety will result in an exponential decrease in the system’s value. Hence we choose the increasing RTS value curve, which is shown above. Flight Enjoyment High flight enjoyment will maintain the ‘joyride’ aim, and serve to keep the system viable for all customers. Undesired levels of flight enjoyment will decrease system value exponentially. Therefore we choose the increasing RTS curve Space Experience Enjoyment This performance measure exhibits similar behaviours as the previous Flight enjoyment measure, and hence we will use the increasing RTS curve. Development Costs High development costs mean that the overall system value will be reduced. As development costs are reduced, the system value increases linearly. Hence, we use the Linear RTS value curve shown below:

Linear RTS [30]: Calculated equation: y = x End User Cost Per Seat The most desired value here corresponds to the lowest end-user cost. However, if the end-user cost is too low the venture will not be viable. Also, if the end user cost is too high, then interest in the venture will be low. Hence, there exist a point in equilibrium which accomplished both these objectives, and this relationship is shown by the s-curve below:

Storage of maintenance equipment The ground terminal maintenance hangar is used to store all equipment and facilities to be used in the maintenance of a space transport unit. This function was defined as F_6.3 in the functional analysis and includes all three levels of maintenance, those being basic level, intermediate level and advanced level maintenance services. Two feasible options were presented in regards to the storing of maintenance equipment, these were: 1) Space transport unit storage hangar 2) Ground terminal maintenance hangar Although any space transport unit would spend the majority of its time in the space transport unit storage hangar, it was decided that the more suitable option would be to construct another hangar designated solely for maintenance. Hence the ground terminal maintenance hangar was chosen to be implemented for this reason. To have a maintenance operation that is separate to the storage system has one key advantage, this being that all maintenance operations are carried out away from space transport units which do not require maintenance which in turn reduces the likelihood of an overcrowded workplace for the maintenance staff. Although the cost of constructing two separate hangars will be larger, the advantages of applying the separation between storage and maintenance will outweigh the initial cost burden.
Disposal System The system lifecycle is highly dependant on the effectiveness of the disposal system. The disposal system is not only used at retirement but also used in the sustainability of the project. The disposal system encompasses three aspects of waste from any retiring / failed equipment, these being hazardous waste, recyclable waste and non recyclable waste as defined in F_7.0. The disposal system is responsible for the separation and the eventual disposing of all products which are no longer required in their current function. The disposal system will therefore cover not only the space transport unit but also the ground terminal and all other supporting facilities. The disposal system could be operated in two ways as described below: 1) Disposal carried out internally
203
2) Disposal carried out by a hired company There are obvious advantages and disadvantages to each of these solutions. Cost is of high importance in all business areas however, the hiring of an external company to remove any waste would be advantageous with regard to any government regulations. For example the employment of a professional waste removal company would eliminate the need for our system to comply with the associated government regulations which are required to be met when dealing with hazardous waste products. The recycling of useful parts however would be more easily accomplished within the system as this can include small tasks which maintenance staff employees are capable of achieving. With this in mind the solution to a choice of waste management through disposal of the system is best suited to be undertaken internally. This eliminates the cost of hiring an external company and also allows recyclable waste to be reused or sold more efficiently as described in F_7.1, F_7.2 and F_7.3.
Space transport unit storage hangar The space transport unit must be stored in a hanger when not in use. The appropriate hanger must be used to cater for all space transport vehicles and for the weather conditions. As defined in function F_1.4.2 The system requirements state that the ground terminal shall have a hangar capable of storing at least 5 space transport units. With the space transport units having the following dimensions: Wing span: 28.4m Overall length: 37.8m Tail height: 8.9m With these dimensions the hangar must be 62mtr × 209mtr × 15mtr , this gives sufficient clearance for the height of the vehicle and 2 meters of space around each vehicle for movement. Hangar Style It is necessary to have the correct hangar style for the space transport unit, the typical styles are as follows. -Segmental Tied Hangar The segmental tied hangar is constructed of segmental tied trusses which are able to span up to 200m or more.
204
-Glove Hangar Glove hangars are an economic solution to aircraft storage, where economy is achieved by the hangars fitting tightly around the aircraft. This reduces the amount of materials used and inturn lower costs. The doors are customised to fit specific aircraft and the nose/fuselage section of the hangar is reduced in size. The smaller internal space also makes the building cheaper to cool or heat. This design does not cater for the space transport unit. The small dimensions only allows for one Space Transport Unit, this would mean that at least 5 hangars are to be constructed for all space transport units to be stored, it would also be difficult to perform maintenance on the space transport unit due to its fitting nature.
-Spine Truss Hangar Spine truss hangars have the dimensions of very short and wide. It is a cost effective solution, however it would not be able to cater for the Space Transport Unit due to the shallow depth of the hangar.
-Cantilever Hangar Cantilever hangars are ideal mostly for long extensions. It needs a substantial office/workshop zone behind the hangar to act as a counterweight. The hangar can extend as long as one kilometre but is restricted to the length/size of the office/workshop behind the hangar. This option would seem feasible since it is cost effective and meets the
205
required dimensions for the Space Transport Unit storage, however it is not know whether the counterweight building behind the hangar has the required length for the size of the hangar.
-Butterfly Hangar The butterfly hangar is made for time efficiency. It needs an apron on both sides, which allows fast access to the stored vehicle. This design is a possible option, however the cost of the butterfly hangar is higher than other designs.
Hangar Roofing/Wall Cladding The material the hangar is composed of is necessary to analyse. It shields the Transport Unit from environmental effects and gives it security and protection. It is desirable for the temperature of the hangar to be kept at a constant room temperature. This will decrease expansion/contraction of the facility and will be an easier environment to work in. There are three different types of roof/wall cladding for different situations. Single Skin Single skin sheeting is the most economic material suitable for roof/wall cladding. It is composed of a single layer of metal over the steel frame, providing little insulation. The single skin is a possible option, however it lacks insulation therefore the hangar will reach high temperatures when it is hot and low temperatures when it is cold. This is an undesirable effect. Double Skin Double skin sheeting is a more expensive material. It is composed of an outer material made of galvanised iron with a small insulation gap and a fibre glass inner skin. It reduces condensation, temperature change and the chance of leakage. It is the most cost effective solution for insulation.
206
Composite Double Skin The Composite Double Skin provides more insulation than the double skin. It is composed of a sandwich panel with a foam core for insulation. It is more expensive than the double skin but is a greater insulator. Design Criteria for Space Transport Unit Storage System While all hangars were analysed only the segmental tied hangar and the butterfly hangar were physically able meet the size requirements of the Space Transport System. The advantage of the segmental tied hangar is the financial cost while it may take longer to get to the runway. While the butterfly hangar has a significantly higher cost however allows efficient transport due to aprons being on both sides. The Space Transport Systems flights are not as regular as normal flights therefore time efficiency is not a great factor. Therefore the segmental tied hangar is preferred. From the three skin materials the most effective when taking strength, insulation and cost into account is the Double Skin. It is a mid ranged material that provides adequate insulation with a U value from 0.45W/oC/m2 - 0.2W/oC/m2. The composite double skin is a more expensive alternative however the cost is significantly higher for a small difference in insulation. While the single skin provides an insignificant amount of insulation.
Ground terminal maintenance hangar The Ground Terminal maintenance equipment must be stored in a maintenance hanger when not in use. The appropriate hanger must be used to cater for all ground terminal maintenance equipment and for the weather conditions. The system requirements state that the Ground Terminal maintenance hangar shall store all ground terminal maintenance equipment and have the dimensions of at least 100mtr × 150mtr × 15mtr . As defined in functional analysis F_1.4.2 The maintenance hangar must be kept at a constant temperature of 25oC this is to maintain the life of the equipment and allow for a comfortable working environment. Therefore the skin material for the roofing and wall cladding must have insulation. The room must also have air conditioning and heating to assist temperature control. Hangar Roofing/Wall Cladding The material the hangar is composed of is necessary to analyse. It shields the maintenance equipment from environmental effects and gives it security and protection. It is desirable for the temperature of the maintenance hangar to be kept at a constant room temperature. This will decrease expansion/contraction of the facility, prolong the equipment life and will be an easier environment to work in. There are three different types of roof/wall cladding for different situations.

Double Skin Double skin sheeting is a more expensive material. It is composed of an outer material made of galvanised iron with a small insulation gap and a fibre glass inner skin. It reduces condensation, temperature change and the chance of leakage. It is the most cost effective solution for insulation. Composite Double Skin The Composite Double Skin provides more insulation than the double skin. It is composed of a sandwich panel with a foam core for insulation. It is more expensive than the double skin but is a greater insulator. Design Criteria for Space Transport Unit Storage System From the two skin materials the most effective when taking strength and insulation into account is the Composite Double Skin. It is provides higher insulation than the double skin but at a higher cost.
Security of the space transport unit hangar For security surveillance of the space transport unit hangar, there are 2 kind of feasible security surveillance systems that could be considered for this application, these are: 1) The use of CCTV surveillance 2) 24 hour security guards CCTV (Closed-circuit television) is a television system that uses surveillance cameras to do the video surveillance. The CCTV is different from broadcast television in that all components are directly linked via cables. The use of CCTV is to deter unauthorised people from entering into the space transport unit hangar at all times. However the CCTV also can be placed in remote area or surround the space transport unit hangar which enables the premises to be monitored at all times. An advantageous function of the CCTV is that, it can record the entire area at all times giving us the best surveillance. We can then play back the recording to see what had happened before. With function of zoom, we can see more clearly, which can help police to identify intruder. The CCTV can provide surveillance 24 hours non-stop everyday, this will provide 24 hours safety of the space transport unit hangar. With advances in technology nowadays, we can install a security door which can be used to restrict unauthorised person to enter to the space transport unit hangar. The security door can design to scan the person’s identification card, fingerprint, eyes, and etc. Because of the CCTV surveillance and security doors, we can leave the space transport unit hangar without the need for a security guide to keep it safe 24 hours a day.
208
Security guards can keep the place safe, but they couldn’t provide complete surveillance for all of the surrounding area at the same time. It is unfeasible to employ large numbers of security guards to surround the space transport unit hangar at all times, this is just wasting manpower and in turn money. The safety they provide can not be guaranteed at 100%, because the guards are capable of human error. This is why the use of CCTV is the recommended solution to security.
209
Fuel Storage Storage of fuel for the space transport units is vital in the safety and efficiency of the entire system. Although many options for fuel storage are available we can narrow our analysis down to the use of fuel tanks and more precisely whether they are located: 1) Above ground 2) Below ground In a similar fashion to any regular fuel station the choice was made to go ahead with the plans for below ground fuel tank construction. The fuel storage facilities consist of fuel pumps and underground tanks located under the ground terminal. The facility makes the fuelling process more convenient. It allows more space transport units to re-fuel at the same location without wasting any time. Fuel storage systems were placed underground for three primary reasons: • • •
Reduce fire and explosion risks. Reduce evaporation losses. Reduce condensation problems
Furthermore, problems like rain or surface water accumulation in the impervious containment systems can be avoided. Surrounding buildings to the fuel storage system could be the Ground terminal, hangars, launching base etc. Fuel is highly combustible. It can results in serious fires and explosions which will damage the surrounding buildings or cause severe injury to people. The chances of fire or explosion can be reduced by following safety precautions and by keeping fuel storage facilities in top condition. Large amounts of fuel are needed to operate the space transport units. The storage tank should be able to store such amount in order to ensure that fuel supply is always ready for space transport unit. Hence an underground system is more appropriate than an above ground system as the large tanks are hidden as compared to taking up space on the surface where hazards could occur.
Life Support System Atmosphere The SiO2 Tiles: These tiles protect the spacecraft upon re-entry into earth’s atmosphere. The space shuttles are protected by special silica tiles. Silica (SiO2) is an incredible good insulator. It is possible to hold a space shuttle tile by the edge and then heat up the centre of the tile with a blow torch. The tile insulates so well that no heat makes it out to the 210
edges [4]. The Silica titles are the best option to fulfil this requirement, as per they have been widely in use before, have no reliability issues and have no competition. Temperature Space temperatures have extremely cold weather conditions and it is constantly changing in different parts of the orbit. However, the electronic equipment generates more than enough heat for the ship. The problem is getting rid of the unwanted heat and do that we need temperature control system have to these major functions. •
Distribute heat where it is needed on the orbiter (mid-fuselage and aft sections) so that vital systems do not freeze in the cold of space [10].
•
Electrical heaters - use electrically-heated wires like a toaster to heat various areas [10].
•
Active methods - more complex, use fluid to handle large heat loads, require maintenance [10].
•
Cold plates - metal plates that collect heat by direct contact with equipment or conduction [10].
•
Heat exchangers - collect heat from equipment using fluid. The equipment radiates heat to a fluid (water, ammonia) which in turn passes heat on to Freon. Both fluids are pumped and recirculated to remove heat [10].
•
Pumps, lines, valves - transport the collected heat from one area to another.
•
Radiators - located on the inside surfaces of the cargo bay doors that radiate the collected heat to outer space [10].
•
Heat released from the Freon causes the ammonia to boil [10].
Because these methods have been used and tested by NASA. Therefore is no other better solution of our currently technology are better and more efficiency therefore our system will use them the same way as NASA does. Pressure The airlock is normally located inside the mid deck of the spacecraft's pressurised crew cabin. It has an inside diameter of 63 inches, is 83 inches long and has two 40-inchdiameter D-shaped openings that are 36 inches across. It also has two pressure-sealing hatches and a complement of airlock support systems. The airlock's volume is 150 cubic feet. Airlock pressurisation is controllable from the orbiter crew cabin mid deck and from inside the airlock. It is performed by equalising the airlocks and cabin's pressure with equalisation valves mounted on the inner hatch. The airlock is depressurised from inside the airlock by venting the airlock's pressure overboard. The two D-shaped airlock hatches open toward the primary pressure source, the orbiter crew cabin, to achieve pressure-
211
assist sealing when closed [11]. Due to NASA’s air-lock system already in use in most spacecraft, its seems the most logical answer to this requirement as it has been used widely before and has no reliability issues and has no competition. Crew compartment cabin pressurisation The cabin is pressurised to 14.7 psi, plus or minus 0.2 psi, and maintained at an average 80-percent nitrogen and 20-percent oxygen mixture by the air revitalisation system. Oxygen partial pressure is maintained between 2.95 and 3.45 psi, with sufficient nitrogen pressure of 11.5 psi added to achieve the cabin total pressure of 14.7 psi, plus or minus 0.2 psi. The pressurisation system consists of two oxygen systems and two gaseous nitrogen systems. The two oxygen systems are supplied by the PRSD oxygen system, which is the same source that supplies oxygen to the orbiter fuel cell power plants. The PRSD cryogenic supercritical oxygen storage system is controlled by electrical heaters within the tanks and supplies the oxygen to the ECLSS pressurisation control system at a pressure of 835 to 852 psi in a gaseous state. The gaseous nitrogen supply system consists of two systems with two gaseous nitrogen tanks for each system. The nitrogen storage tanks are serviced to a nominal pressure of 2,964 psi at 80 F. If the auxiliary gaseous oxygen supply tank is installed, it is serviced to 2,440 psi at 80 F and stores 67.6 pounds of gaseous oxygen to provide high flow along with gaseous nitrogen. It would maintain the crew cabin at 8 psi with oxygen partial pressure at 2 psi. For normal on-orbit operations one oxygen and nitrogen supply system is used. For launch and entry both oxygen and nitrogen supply systems are used in addition to pressurisation of the airlock [11]. Because crew compartment cabin pressurisation is the most excellent and the only pressure system that are currently been used to maintain an atmospheric pressure by NASA. Therefore is no other better solution of our currently technology are better and more efficiency therefore our system will use them the same way as NASA does.
Space transport unit exterior Silica Fibres The silica fibres are derived from common sand and are made of high purity fibres (2 to 4 microns in diameter, as long a 1/16th inch) derived from common sand. The tile containing silica fibres is frame cast to form soft, porous blocks to which a colloidal silica binder solution is added. The blocks are then dried, sintered at 2300ûF. Machined tiles then go to ovens for baked-on coatings. These tiles experience re-entry heating up to 2300ûF and are coated with white silica compound which includes alumina to better reflect the heat of the Sun on-orbit. All tiles are treated with a waterproofing polymer [13]. High temperature reusable surface insulation tiles
212
This HRSI tiles are made from a low density and high purity silica 99.9% and fibres are derived from command sand of 1 to 2 mils tick. The insulation that made ridged by ceramic bonding. The weigh of this tiles about 9 pounds per cubic foot. The thickness is determined by the heat load encounter during entry. HRSI tiles are vary in size and shapes in the close out areas on the orbiter. The HRSI tiles withstand on orbit cold soak condition and repeated heating and cooling thermal shock and extreme acoustic environments about 165 decibels at launch. Because HRSI tiles are small, have been used widely, and are reliable and safe, these are to be used. For the controller, because a NASA air- system has been widely used before has no reliability issues and has no competition; this system is to be used.
Space Navigation Space vehicle navigation comprises two aspects: (1) Knowledge and prediction of the space vehicle’s position and velocity, which is orbit determination, and (2) Firing the rocket motor to alter the space vehicle’s velocity, this is flight path control. The primary system used throughout the world for space-based positioning, navigation, and timing is the Global Positioning System (GPS), a constellation of satellites providing continuous civil service free of direct user charges to an unlimited number of users for peaceful purposes. Additionally, GPS is critical to a wide range of civilian activities and represents a fundamental component of the global information infrastructure [15]. Figure 1.1 below shows the locations of the existing placements of GPS systems.
To determine the orbital position of the space vehicle, the imaging instruments on board the vehicle can use them to observe the spacecraft's destination planet or other body, such as a satellite, against known landmarks. The observations are carefully planned and up linked far in advance as part of the command sequence development process. The primary body often appears in these images, which are known as opnavs, so that the background stars will be clearly visible. When the opnav images are down linked in
213
telemetry (TLM) they are immediately processed by the navigation team. Interpretation of opnavs provides a very precise data set useful for refining knowledge of a space vehicle’s trajectory as it approaches a target, or otherwise addressed as flight control. There are several types of navigational systems that could be used for space navigation. This comprises of: 1) 2) 3) 4) 5) 6)
Galileo satellite navigation GLONASS navigation system Quasi-Zenith Satellite System Beidou satellite navigation Euridis navigation Multifunctional Transport Satellite (MTSAT-1R)
The Galileo satellite navigation program is a joint initiative between the European Union and the European Space Agency to build and operate a 30-satellite constellation that provides similar capabilities to GPS, but as a commercially-operated, for-profit venture, not a public good. The system will offer four distinct positioning, navigation, and timing services and one search and rescue service. GLONASS is a Russian space-based navigation system comparable to the U.S. GPS system. The fully operational system will contain 21 satellites in 3 orbital planes, with 3 on-orbit spares. The GLONASS system is managed for the Russian Federation Government by the Russian Space Forces providing benefits to civil users through a variety of applications. The GLONASS system has two types of navigation signals: standard precision navigation signal (SP) and high precision navigation signal (HP). SP positioning and timing services are available to all GLONASS civil users on a continuous, worldwide basis. On December 10, 2003, three GLONASS spacecraft were placed into orbit in Plane 1, including one of the new generations of GLONASS-M satellites. The addition of these three satellites will bring the GLONASS constellation to a total of 11 operational satellites. The Quasi-Zenith Satellite System [Jun-Ten-Cho in Japanese] is a constellation of at least three satellites, configured such that one of them is always positioned at a high elevation angle over Japan. RF transmission will not be obstructed by tall buildings or mountains, because one of satellites will always remain near high in the sky over Japan at all times. As a result, signal degradation caused by building blockage and multiple signal paths will be less frequent, making the whole system ideal and reliable for mobile data communication and broadcasting. The system is also expected to increase accuracy to GPS users in the eastern Asia area. Although China has not yet established operational satellite navigation and positioning network, research for such a system has been underway for many years, and a future space-based navigation capability is an acknowledged goal. Beidou ('Big Dipper') is the satellite component for the independent Chinese satellite navigation and positioning system. The Beidou satellite navigation and positioning system are consists of two
214
satellites in geosynchronous orbit. The final Beidou constellation will include four satellites, two operational and two backups. Together with the ground stations, the Beidou system will provide navigation and positioning signals covering the East Asia region. However, to provide global signal coverage, satellites flying in other orbits around the world must complement the system. The Euridis satellite navigation system developed by Alcatel Space, as Prime Contractor, provides France's initial contribution to the EGNOS programme, the European component in the first-generation worldwide navigation satellite system (GNSS-1). The system was ordered by CNES. In the context of the EGNOS programme, Euridis provides users with a permanent navigation signal in addition to those supplied by the GPS (American) and GLONASS (Russian) constellations. This signal significantly increases the availability and integrity of the user's position. Euridis navigation service will be available in the Inmarsat 3 AOR-E satellite footprint area [18]. The Multifunctional Transport Satellite (MTSAT-1R) multi-mission space programme comprises a space segment which will eventually consist of two geostationary satellites and an earth segment. Alcatel Space is playing a leading role in this aeronautical mission and in the production of traffic and earth control stations [18]. MTSAT-1R is being built for Japan and will be the first air navigation and telecommunications space system to meet the CNS/ATM concept adopted by the International Civil Aviation Organisation (ICAO) in 1991. Design Criteria for Space Rocket navigational System For the joyride to Space program, there are 2 feasible navigational systems that could be considered for this application, namely: 1) Galileo satellite navigation 2) Euridis satellite navigation system While most of the other satellite navigational systems are publicly offered, the Galileo has a 30-satellite constellation, which offers the most coverage among other satellite navigational system. The added feature making this navigational system attractive is also the ability to provide a search and rescue service, which is an added safety feature. However, the cost factor needs to be addressed when choosing this system as it is a commercial package. The Euridis satellite navigation system takes advantage over the other two by combining both the GPS (American) and GLONASS (Russian) constellations. However, it does not provide search and rescue services.

Radio communications In voice communication, space transport should provide communication via UHF and HF transmission allow to transmitting data between space transport and ground. All voice in HF frequency is in AM mode. The UHF transmission provided high transmission rate which for voice and video communication. There are some frequencies which need to consider for UHF transmission provided by Scott [19]: a. 1831.787 - US Dept of Defence Uplink to Space Shuttle[19] b. 2085.6875 - S Band Uplink to Space Shuttle [19] c. 2106.4 - Command Uplink [19] d. 2119.8 - Space Shuttle - Payload Link Frequency [19] e. 2217.5 - TDRS Satellite link [19] f. 2250.0 - WFM - Analog Data and Telemetry during Space Shuttle Launch [19] g. 2265.0 - S Band Downlink [19] h. 2287.5 - ISS Zarya Module / Space Shuttle [19] i. 2298.8 - Payload - Space Shuttle Link Frequency [19] We have chosen the option ‘i’ because the higher frequencies range of transmission, the more efficiency data transmission on communication. Therefore, this would be providing customers to enjoy quality and high performance of voice and video communication between ground and space transporter. However, there are some HF frequencies provided by Scott [19] which is showed below: a. 8.364 - Morse Code heard during recovery of Russian Space Vehicles b. 9.019 - AM - Used for Vostok 1 [19] c. 10.003 - Common Recovery Beacon frequency [19] d. 15.008 - AM - Early Salyut / Soyuz [19] e. 15.016 - AM - Mercury 7 Frequency [19] f. 15.763 - AM - Used for Vostok 2 [19] g. 17.365 - AM - Used for the Voskhod missions [19] h. 18.035 - AM - Used for Voskhod / early Soyuz missions [19] i. 18.060 - AM - Old Soyuz frequency / Used During recovery of Russian [19] We found that the HF feasible frequencies for HF transmission are 15.016 MHz. The reason to choose this because it is been used in space craft called “Mercury 7” and we decide our space transporter is more suitable using this frequencies band which is 15.016 MHz in AM mode for voice communication.
Video Communications The space transport should provide at least 12 inches of LCD monitors for video communication. We decided to use 12 inches of LCD screens monitors which able to send quality video images according to specification of LCD monitors provided by Caltron Industries [20]. The following specification is showed as below:

Communications Antenna The space transport communications system should have at least 2 antennas for tracking the signal from ground to space transport. The function of antennas is to receive and transmit the data between ground and space transport. According to ATCI [21], there is specification which related to antenna on space transport: For Simulsat 5 • Most Frequently Installed Model Worldwide • Standard and High Mount Available • C and Ku-Band Capability • Performs equivalent to 4.5 m. C-Band Prime Focus Parabolic Antennas • Receives, with uniform performance, signals from all satellites within a 70° view arc. • Requires Less Space – Takes up the same space as 3 parking spaces.
217
For Simulsat 7 • ATCi’s largest Simulsat model – geared toward large cable systems and teleports. • Standard and High Mount Available • More arc coverage – receives, with uniform performance, signals from all satellites within a 75° view arc. • C and Ku-Band Capability • Performs equivalent to 6 M. C-Band Prime Focus Parabolic Antennas. We decided to use Simulsat 7 because it is more reliable and able received strong signals. Therefore, it might improve the data transmission as well.
Tracking system The space transport communication system provides a tracking subsystem via C-band. According to Telesat [22], there is some specification which provided as following: Option 1

We have chosen option 1 because the power consumption is less and the C-band channel will be equally same as option 1. So, there might cut the cost also to build tracking system via C-band.
Space to ground tracking system The space to ground communication provides tracking system via S-band. Paul J. Marsh [23] defined the definition of S-band is the range of frequencies from around 1.55 GHz through to 3.9 GHz. There is other more well knows devices that transmit at s-band. These include microwave ovens on 2.450 GHz, and the new breed of wireless videosenders which also operate around the 2.4 GHz mark. Other services to be found include video downlinks from police helicopters, outside broadcast events and blimp type balloons with cameras on board. The initial success of the helical antenna for L-band led me to redesign the antenna for s-band. After spending some time researching the various downlinks on s-band, a left hand circular antenna was build to feed the dish, resulting in right hand circular reception. The advantage of the helical is its wide bandwidth, having a minus 20% and plus 30% bandwidth with respect of the design frequency. The centre 218
frequency I chose is 2.25 GHz, so the antenna will be usable from 1800 MHz to 2925 MHz. This is quite wideband, but I'm using it round the 2.2 GHz mark, with about 200 MHz either side. This picture is not of a helical but of the S-band dipole used to test. [23]
Figure 3: Example photo captured by S-band satellite. (Courtesy by Paul J. Marsh )[23] From here, our team decided to use the tracking system for S-band compared to other bands due to costly and low quality resolution of images which performed from other bands. It provides a very clear picture which captured by using S-band satellite.
Propulsion subsystem The propulsion system is required to be able to provide at least 95kN of thrust. The TX354-3, RL-50, Airane-HM-7B, Vinci, and Vulcain, all meet this requirement. From the specifications we have chosen to use the Vinci Engine. Vinci Designer: Astrium. Propellants: Lox/LH2 Thrust(vac): 15,700 kgf. Isp: 467 sec. Chambers: 1. Country: Germany.

The Vinci specification more closely matches the thrust we require 155kN compared to 200+ for the other engines. This engine will provide enough thrust to lift the Space transport unit to space and accelerate at a speed which is comfortable for the passengers. It also has an additional safety feature of being able to be restarted during flight. The Specifications for the Engines can bee seen below in Figure Engine1.

Table Propulsion1- Main engine Vinci Specifications The thrusters for the propulsion system will be used to maintain the stability of the space transport unit. The Thrusters we have considered are the DOK-10 and CHT-5. DOK-10 Designer: Isayev. Propellants: Hydrazine Thrust(vac): 1 kgf. Thrust(vac): 0.010 kN. Isp: 229 sec. Burn time: 1,500 sec.

Table Propulsion2. Thrusters Specifications CHT-5
The propellent used to fuel the Engines in Liquid Hydrogen and liquid Oxygen. The propellent used to fuel the thrusters is Hydrazine. Fuel is required to be kept storage tanks that comply with any government regulations and safety procedures relating to the handling and storage of such chemicals. These tanks are required to be large enough to accomplish 1.5 space flights.
Launch system runway According to Simon Rowland [1], for a 200 passenger space transport, the space transporter runway should withstand 830 tonnes, Our team has decided to withstand approximately 850 tonnes on the runway. The runway should be able to take all specifications and requirements such as runway shall at least withstand a static weight of 120 tonnes. According to Sydney airport [1], two runway surface specifications which are RWY 07-25 and RWY 16L-34R showing the following: RWY 07-25 (Option 1) Width: 45 m Length: 2529 m Pavement: Asphalt/Flexible Subgrade: High Strength Characteristics: Grooved RWY 16L-34R (Option2) Width: 45 m Length: 2438 m Pavement: Asphalt/Flexible Subgrade: High Strength Characteristics: Grooved
221
Refer to both runways above, our team has decided that option 2 is more reliable and easy to maintain runway. Therefore, the characteristic of runway shall be treated with groove skid resistant material and the length of the runway shall be approximately in 2.5 Km.

1. INTRODUCTION A Portfolio divides teams into different aspects where each team then contributes towards the final outcome of the project. These teams contribute a collection of documents describing their perspective towards the project. These documents describe in detail about each requirement. Taken from the requirements, it has been broken down to each sub-section and explained in more detail the purpose of the requirement from each aspect, which is the technical part, the non-technical part, the safety
part and the system aspects part. A detailed explanation from each of these sections provides a clear view of the purpose of the requirement.
2. Navigation Portfolio Identifier: PORT_01 Requirement: The system shall provide two-dimensional (latitude and longitude) coverage of the space transport unit in space. Technical: Latitude measures the angle ranging from 0° at the Equator to 90° at the poles and the longitude is also measured in angles ranging from 0° at the Prime Meridian to +180° eastward and −180° westward Latitude measures the angle ranging from 0° at the Equator to 90° at the poles and the longitude is also measured in angles ranging from 0° at the Prime Meridian to +180° eastward and −180° westward The latitude and longitude coverage will provide the space transport unit’s co-ordinates to the ground station. Safety: The co-ordinates will enable the ground station to track the space transport unit’s position. Tracking the space transport unit is for safety precautions in case any incidents may occur, so emergency and rescue services could perform efficiently if the exact locations of events are known. Non-Technical: The two-dimensional co-ordinate system is required as a safety precaution. System Aspect: The two-dimensional co-ordinate system is required to be part of the navigation system, mainly for the safety of the public, customers and employees, and also as security for the space transport unit. Portfolio Identifier: PORT_02 Requirement: The system shall provide three-dimensional altitude coverage of the space transport unit in space. Technical: The three-dimensional altitude provides the location on, in, or above the Earth, the elevation, and the height position of the space transport unit. The threedimensional coverage will provide the location, the elevation and the height position of the space transport unit to the ground station. Safety: The three-dimensional altitude coverage will enable the ground station to track the space transport unit’s altitude position. Tracking the space transport unit is for safety precautions in case any incidents may occur, so emergency and rescue services could perform efficiently if the exact locations of events are known. Non-Technical: The three-dimensional altitude system is required as a safety precaution. System Aspect: The three-dimensional altitude system is required to be part of the navigation system, mainly for the safety of the public, customers and employees, and also as security for the space transport unit.
Portfolio Identifier: PORT_03 Requirement: The system shall also be able to determine the position of the space transport unit under different weather conditions. Technical: The system shall require access to satellite constellations. The satellite navigation systems should be able to interoperable with older navigation systems. With the combine systems, it can improve the overall navigation availability, because the user will be able to locate moving or stationary object with the same receiver from any of the satellites in any combination. Safety: The tracking system needs to be constantly providing the space transport unit’s position information at all time. Any long length of time of break down in communication could have severe consequences if any incidents may occur. Non-Non-Technical: The ability of changing satellite combinations will allow ground control to keep track of the space transport unit with minimising the time of break down in communication. System Aspect: The tracking system is required to operate under different weather conditions. For a reliable system, it should be part of the navigation system prerequisite, mainly for the safety of the public, customers and employees, and also as security for the space transport unit. Portfolio Identifier: PORT_04 Requirement: The system shall be able to have time synchronisation accuracy with the space vehicle up to 0.1 microseconds. Technical: The navigation system fitted with an atomic clock improves the measured accurate. This allows the system to calculate the exact position with an accuracy of up to 0.1 meter/second. Safety: Allows the space transport unit and the ground station to obtain data as quick as possible, to avoid incidents. Non-Technical: Enabling the system to obtain data in real-time. System Aspect: The navigation system providing data in real-time is required to update its system data and to improve performance.
3. Propulsion System Portfolio Identifier: PORT_05 Requirement: The system shall have at least one main engine. Technical: One main engine can provide enough thrust for the space transport unit to take off and fly safely. Too many engines would put too much weight on the transport unit. With today’s technology one engine is capable of providing enough thrust for a space transport unit. Safety: An engine weighs a lot, and too many engines may weigh the space transport unit down. If the main engine is down, there will be a secondary engine as back up. Non-Technical: Too many engines per transport unit will strain the construction and maintenance budget and the consumption of fuel will also increase. System Aspects: Technical and safety must be considered to make the decision on whether of using how many engines. Portfolio Identifier: PORT_06 Requirement: The engine shall be able to provide at least 95 kN of thrust.
Technical: This is more than enough thrust for injection for the transporter into earth orbit. This amount of thrust is obtainable using today’s rocket engine technology; with current rocket technology able to maintain this level of thrust for well over 200 seconds. Safety: Although much higher levels of thrust are capable from current rocket engine technology, higher levels of thrust will result in G-forces that are not tolerable for human passengers. Non-Technical: The amount of thrust that an engine can produce will determine the price. It is unnecessary to pick an engine and the transport unit will not use the full potential of the engine. System Aspects: All technical, non-technical and safety must be considered to make the decision on how much thrust is the best solution for the space transport unit.
4. Launch System Portfolio Identifier: PORT_07 Requirement: The system shall have at least one runway for take-off and landing. Tech: Aspects of the runway will improve efficiency and enable the Ground terminal to organise launch sequences. Safety: The runway allows for enhanced safety precautions. Emergency vehicles can be close in case they are needed urgently, Patrons and customers can be kept clear of the area. Accurate simulations can be performed in the case of an emergency. Non-tech: A runway is required for a comfortable take off [3]. System Aspects: Portfolio Identifier: PORT_08 Requirement: The runway shall be able to withstand a static weight of 120 tonnes. Tech: The static weight of 120 tones will be able to withstand any space transport unit movements, and prevent damage occurring Safety: The static weight is adequate to be able to move the space transport unit with out causing damage to the space transport unit or the runway. Non-tech: The static weight of 120 tone will allow multiple take-offs and landings on the runway, which will decreases overall costs [3]. System Aspects:
Portfolio Identifier: PORT_09 Requirement: The runway shall be able to withstand an impact of 1.30x3 Nm. in an area of 4 m2. Tech: The required impact pressure for damage not to occur to the runway under full thrust conditions on take off and during the landing of the space transport unit. Safety: An impact resistance of 1.30x3 Nm is more than adequate to safely land the space transport unit. Non-tech: Withstanding an impact of 1.30x3 Nm will allow multiple take-offs and landings on the runway, which will decreases overall costs [2]. System Aspects: Portfolio Identifier: PORT_10 Requirement: The runway shall be treated with skid-resistant material (grooved or PFC) per FAA or ICAO specifications. Tech: This requirement allows for better mobility and increased stopping ability. By using no skid-resistant material the tyres will last longer and save on maintenance Safety: This requirement allows for better mobility and increased stopping ability. Non-tech: Increased comfort, knowing that safety precautions are being implemented [2]. System Aspects: Portfolio Identifier: PORT_11 Requirement: The runway shall be of length no less than 1.5 km. Tech: A runway of 1.5km will be sufficient to be able to take off and land the space transport unit. Non-tech: Runway costs are about $8000000US per 350m. A short runway will reduce costs but a Long runway will give a greater feeling of comfort to passengers. Safety: A runway of length of 2.5km will adequately allow the Space transport unit to abort take-off at any time during the launch sequence and stop before the runway ends. At 1.5km some additional run-off ramps will be required. These run-off ramps may be made of a slightly less grade material [3]. System Aspects:
5. Life Support Portfolio Identifier: PORT _12 Requirement: The system shall maintain temperature control for life support within the range of 8°C to 27°C (64°-81 °F). Technical: Outer space is an extremely cold environment and temperatures will vary drastically in different parts of the space transport unit orbiter. The electronic equipment generates more than enough heat for the ship. The problem is getting rid of the excess heat. So the temperature control system has to carry out two major functions: • Distribute heat where it is needed on the orbiter (mid-fuselage and other sections) so that vital systems do not freeze in the cold of space. • Insulating materials, surface coatings are used to reduce heat loss through the walls of the various components just like your home insulation. • Metallic plates are used to collect heat by direct contact with equipment or conduction The cabin heat exchanger also controls the cabin temperature. It circulates cool water to remove excess heat (cabin air is also used to cool electronic equipment) and transferring heat to warm up the colder section of the space transport unit orbiter. Safety: To our knowledge these temperature controlling systems are safe. An ambient temperature range of 21 to 23oC (70 to 74oF) is optimal for system reliability and operator comfort. While most computer equipment can operate within a rather broad range, a temperature level near 22oC (72oF) is desirable because it is easier to maintain a safe associated relative humidity level at this temperature. Further, this recommended temperature provides an operational buffer in case the environmental support systems are down [5]. Non-Technical: There will be a cost associating to the components that is required, and NASA has already performed their own cost analysis over many uses. System Aspects: It ensures the survival of the passengers on board the shuttle. Portfolio Identifier: PORT_13 Requirement: The space transport unit shall handle no less than 3,000 degrees F (1,650 degrees C) of heat generation (for re-entry to earth). Technical: Space transport unit will require a heat shield, because it will be exposed to extreme heat (up to 2300ûF) during re-entry. Not all parts of the transport unit will experience the extreme heat, some sections may only be exposed to lower temperature, from 600û to 1200ûF, so not all sections requires the same type of heat shield [11]. Safety: Heat shield prevents the space transport unit from burning up during re-entry. Non-Technical: Cost will very depending on the types of material used for the heat shield, different parts will be protected by different types of heat shield. The heat shield is re-usable [8]. System Aspects: It ensures the survival of the passengers on board the shuttle.
Portfolio Identifier: PORT _14 Requirement: The exterior of a space transport unit shall handle no less than 760 millimetres of mercury pressure. Technical: The airlock is normally located inside the mid deck of a spacecraft's pressurised crew cabin. Airlock depressurisation is controllable from the orbiter crew cabin mid deck and from inside the airlock. It is performed by equalising the airlocks and cabin's pressure with equalisation valves mounted on the inner hatch. The airlock is depressurised from inside the airlock by venting the airlock's pressure overboard. [4]. Safety: To our knowledge their have been no safety issues with NASA's air pressure system. Each airlock hatch has dual pressure seals to maintain pressure integrity. One seal is mounted on the airlock hatch and the other on the airlock structure. A leak check quickly disconnect is installed between the hatch and the airlock pressure seals to verify hatch pressure integrity before flight [4]. Non-Technical: NASA has already performed their own cost analysis over many use we will follow their use of components. System Aspects: It ensures the survival of the passengers on board the shuttle. Portfolio Identifier: PORT_15 Requirement: The interior of the system shall maintain an atmospheric pressure of 14.7psi at all times (half of FAA allowance of pressure variation, assuming a linear decrease in pressure with height) [13]. Technical: The cabin is pressurised to 14.7psia, plus or minus 0.2psia, and maintained at an average 80-percent nitrogen and 20-percent oxygen mixture by the air revitalisation system. Oxygen partial pressure is maintained between 2.95 and 3.45psi, with sufficient nitrogen pressure of 11.5psia added to achieve the cabin total pressure of 14.7psia, plus or minus 0.2psia [12]. Safety: Although much higher levels of thrust are capable from today’s spaceship technology. This means that spaceships must have strong walls to keep from blowing up due to the internal pressure. Even a six foot diameter sphere has a pressure of about 122 tons trying to blow it apart due to the atmospheric pressure of 15 psi (pounds per square inch) inside the spaceship (if you simulate the atmospheric pressure of the earth [6].) This level of precautions is safe for the structural integrity of the spacecraft, and will also allow all other systems to operate correctly. Non-Technical: Cost: Because NASA has already performed their own cost analysis over many use we will follow their use of components atmosphere. System Aspects: It ensures the survival of the passengers on board the shuttle.
6. Maintenance Portfolio Identifier: PORT_16 Requirement: Any hazardous materials used in design of the Space Transport Unit shall be separated at unit retirement as described by the Basel Convention on the Control of Trans-boundary Movements of Hazardous Wastes and their Disposal. Technical: Hazardous material used to design Space Transport Unit could be solid, liquid or gas that can harm humans or other living organisms due to being radioactive, flammable, and explosive etc. The hazardous material should be stored in a closed container under a dry-insert blanket. The storage area should be ventilated and the room temperature kept at 4ºC. The hazardous material requires separate unit retirement, to keep it safe. Safety: To ensure the safety of the person who handles the hazardous material, that person has to wear the protective clothing to protect him or herself from the hazardous materials. Special protective clothing has been treated to offend hazardous chemical, biological or radioactive materials. We have to ensure that, a First–Aid kit is provided near the storage area. Non-Technical: The hazardous materials could be solid, liquid or gas; therefore we have to keep the container safe. We have to avoid exposing the container to the atmosphere, because those hazardous materials could diffuse through air, which will pollute the air quality and also the environment. System Aspect: The hazardous materials are very dangerous, which will cause serious harm to human health and might lead to death. Therefore, we have to take serious action in separating the hazardous materials at the unit retirement. Portfolio Identifier: PORT_17 Requirement: Any hazardous materials used in design of the Space Transport Unit shall be disposed of at unit retirement as described by the Basel Convention on the Control of Trans-boundary Movements of Hazardous Wastes and their Disposal. Technical: Hazardous materials are very dangerous, which can harm human and living organisms. The disposal of hazardous waste must follow the Basel Convention. The Basel Convention was designed to reduce the movements of hazardous material between nations, and specifically to prevent dumping of hazardous waste from developed to less developed countries (LDC). Safety: The hazardous waste are dangerous objects, therefore we have to be very careful while disposing them. The disposal process needs to follow the way which is stated in the government and local environmental control regulation. Non-technical: To dispose the hazardous waste, special disposal company is needed to dispose the hazardous waste. The disposal company must be approved by the government. System Aspect: It is important to dispose the hazardous waste by using the correct method and must be in accordance with the government and local environmental control regulations.
Portfolio Identifier: PORT_18 Requirement: Any hazardous materials used in design of the ground facilities shall be separated at retirement as described by the Basel Convention on the Control of Trans-boundary Movements of Hazardous Wastes and their Disposal. Technical: Hazardous material used in design ground facilities maybe solid, liquid or gas which can seriously harm humans or other living organisms. The hazardous material should be stored in a closed steel container under a dry-insert blanket and maintain the room temperature at 4o C. Safety: To ensure the safety of the person who handles the hazardous material, that person has to wear the protective clothing to protect him or herself from the hazardous materials. As describe before, the protective clothing is very powerful which can protect he/she from getting affected. We have to ensure the First-Aid kit is around the storage area Non-Technical: The hazardous materials could be solid, liquid or gas; therefore we have to keep the container safe. We have to avoid exposing the container to the atmosphere, because those hazardous materials could diffuse through air, which will pollute the air quality and also the environment. System Aspect: The hazardous materials are very dangerous, which will cause serious harm to human health and might lead to death. Therefore, we have to take serious action in separating the hazardous materials at the unit retirement.

The temperature will meet the fuel storage temperature. Fuel storage is to facilitate for 6000000ltr of fuel. Non-Technical: The fuel storage is kept underground rather than above ground for space saving. Underground storage is used rather than above ground storage because it is easier to maintain a constant temperature underground rather than above ground, this will reduce the risks of combustion due to the high temperatures in South Australia. Safety: The underground storage space has many advantages in safety. If the storage space is stored above ground it would be susceptible to many safety factors. This includes terrorists, temperature control and security access. System Aspects: Having an underground fuel storage would impact on a larger financial cost than to have fuel storage above ground, underground fuel storage is justified mainly by the safety aspects involved. If the safety of fuel storage is compromised it could result in a possible destruction of the whole ground base. Portfolio Identifier: PORT_26 Requirement: The fuel storage shall be at least 1.5km away from surrounding buildings. Technical: From a technical point of view it is not feasible to have fuel storage 1.5km away. The fuel storage should be close to the hanger. Non-Technical: The fuel storage is located a least 1.5km away from surrounding buildings to facilitate customer satisfaction; it is not pleasurable to know that the customer is situated on top of a large amount of highly flammable fuel. Therefore the fuel storage is located at a distance at least 1.5km from surrounding buildings. Safety: There is a large safety aspect when considering the location of the fuel storage, it is located 1.5km away from surrounding buildings in the case of an accident or explosion of the fuel storage, this distance will minimise any damage to surrounding buildings and personnel. System Aspects: The fuel storage space is located 1.5km away from surrounding buildings mainly from a safety prospective; technically the fuel should be located close to the hanger to make maintenance fast and efficient. Portfolio Identifier: PORT_27 Requirement: The fuel storage shall store 6000000 litres of fuel. Technical: The fuel storage is to have enough fuel to last twenty flights as required by the requirement GT_SC11, this equates to 6000000litres of fuel. Non-Technical: This allows for twenty flights due to the large number of space transport units on mission. Safety: It is not desirable to hold 6000000litres of fuel due to the huge safety concerns. System Aspects: It is not desirable to hold 6000000litres of fuel, however it is specified that the there must be enough fuel for at least 20 flights. This is due to the high demand for space travel.
8. Service Portfolio Identifier: PORT_28 Requirement: All pre-launch maintenance tools shall be stored in the Ground Terminal Storage hangar Technical: As described previously the storage hangar is 100m x 100m x 10m, this technically provides the system with a large enough area to store all the required equipment.

Conclusion: Serious and detailed consideration was first given to the possibility of space being opened up to trips by the general public three decades ago, and some initial attempts to do so around a decade ago, mainly in Russia and the United States. In recent years, professional space tourism studies have been conducted in the United Kingdom, Germany and, especially, Japan and China. In the U.S., technological progress has been pronounced and it has be proven to the general public that it is possible for astronaut travel to and from low Earth orbit safely. NASA and the commercial space industry now have new and promising space transportation development programs underway; especially the space plane X-33 and X-34 programs, and some related development programs [1]. From the feasibility study conducted by the team in this report, a space plane is shown to be the most feasible technology considered for the proposed joyride to space. Today, tourism trips are limited to surface travel or low-altitude flight. Opportunities to experience space-like conditions are limited to "zero-gravity" trips in aircraft and simulations. Even so, over 10 million people each year visit a space museum, a space camp, a rocket launch-recovery site or government space R&D centres -- a business with estimated revenue of $1 billion per year [1]. This business could be expanded, especially if the general public could see programs underway that specifically offer the promise of trips to/from space becoming available early in the next decade. Its expansion would attract entrepreneurs and investment attention to in-space business possibilities and it is a venture that Australia should consider. For Australia’s Space ambitions, Matthew King, author of the journal “The Lowdown”, address the topic of Australian Space development in focus. In this report, he states that Australia should launch a national campaign to be involved in the push to make space travel a commercial reality. If a few Russian or Chinese space engineers could be hired for their experience sharing, this could prove to be an inexpensive option worth pursuing. Space development is also perceived as an economic multiplier as every dollar spent on space percolates through the economy, creating growth and wealth. Space travel is still considered a relatively high risk proposition, due to the cuttingedge technology relied upon. To promote the space tourism industry, operators need to ensure that both the transportation and destination are safe, accessible, and comfortable enough to provide tourists with a positive experience. If travelling patrons get hurt or sick, or if they just have an unpleasant experience, word of mouth will quickly discourage other potential customers. This may be especially true when space tours are accessible only to the rich and famous, whose descriptions of their experiences (favourable or unfavourable) will colourfully capture the public's attention. The system utilising space planes, as described in this document, addresses all of these issues and is sure to be a commercial success for our client, SeaLink.
