Mars Space Settlement 1.0 EXECUTIVE SUMMARY Northdonning Heedwell agrees with the aspirations of the Foundation Society in the development of a space settlement community in the Martian orbit with the capability to act as a financial centre in space, a docking base for ships for ventures into deep space and as a centre for research. We at Northdonning Heedwell hope that man’s dream of finally conquering the heavens is realized and that the proposed Martian Space station plays a prominent role in this process. We are indeed honoured to be chosen as the designers of the path leading to this “dream realized”. The following is in accordance to the Request for Proposal dated 2nd January 2051. Over the years NH has acquired expertise in the design of space stations and requisite technology. Our proposal offers a complete package with very low technical risk. Most of the technologies to be used on Aresam have been successfully tested on Earth and we assure the highest degree of both safety and comfort. In fact, Aresam is designed to be exactly like Earth; minus problems like pollution. This proposal not only describes structural design, development and construction, but also plans for operating and maintaining the Aresam Space Settlement in the Martian orbit. For easy readability the proposal has been subdivided into 6 segments. Some of the more notable features of Aresam are: High standard of living and comfort for all with availability of customized living options Spectacular views of Mars, its moons and of course, the Cosmos Zero/Low-G Recreation Being the furthest human community to date it will be an excellent Station for deep space ventures and astronomical observations High level of automation ranging from cargo handling to household chores A high level of security ranging from Iris Scan Systems (ISS) to Subcutaneous Chips High-Quality educational facilities and working places Well designed living environment with landscaping and wide open spaces An efficient public transit system: The Monorail, runs throughout the settlement. -Page 1- Northdonning Heedwell Structural Design Aresam .::. Mars Space Settlement 2.0 STRUCTURAL DESIGN 2.1 EXTERNAL CONFIGURATION 2.1.1 SHAPE AND DESIGN Northdonning Heedwell has developed an innovative concept for the shape and design of the Aresam Mars Space Settlement that overcomes the limitations of the current design technologies such as the cylinder, dumb-bell, sphere etc. It was decided that a half-cut torus would best suit our requirements. The half-cut toroidal design requires the removal of the outer semi-circle from the cross-section of the torus. The design allows us to control the minor radius which generates the atmosphere volume, which is a very important element in the creation of Pseudo-Gravity (Artificial Gravity) and good biological conditions. Another advantage of the half-cut torus is that it assures maximum habitable area per ton of nitrogen, requiring minimum amount of materials. Figure 2.1 – Schematic Diagram of Aresam Space Settlement Aresam will consist of two half-cut torii, stacked one over the other, a Communications Sphere, two Cylinders with spherical end-caps and a Docking Station. Torus 1 will be used for agriculture and storage. It has been divided into 4 modules for easy management and isolation. Torus 2 will provide the actual living and working space. -Page 2- Northdonning Heedwell Aresam .::. Mars Space Settlement A cylinder with spherical end-caps will be used in the centre of both of the torii for storage, manufacturing, recreation and research etc. We have the advantage of strict Zero-Gravity at the centre and constant Pseudo-Gravity on the end-caps. It can be easily segmented and will contain a dense atmosphere, thus it can serve as a temporary location for the colonists incase of torus evacuation. The lower part will be used for docking, ship repair and cargo handling. The cylindrical docking system will be equipped with state-of-the-art automated emergency handling technologies and has the capability to cater to 15 space vehicles simultaneously. . The Communications Sphere contains the communication equipments which are based on Laser Technology (see Section 3.2.3B). For power generation, solar panels will be placed on the mirror and in between the two torii, which will also provide robustness and stability to the structure. The mirror will not be rotated so as to continuously face the sun. This can be done easily with the help of magnetic bearings. Six spokes will connect each of the torii to the Central Cylinders (the “Core”). Reflective mirrors will be placed along these spokes which will reflect sunlight into the torii. The two torii will also be connected to each other by means of three Shafts; each of these shafts will have a solar panel attached to them. A Central Shaft will be running through the centre of the two cylinders, the Docking Station and the Mirror, towards the Communications Sphere. A moveable sphere will be placed on each spoke between the tourism cylinder and the residential torus. These spheres will provide variable gravity, which will be a novel experience for tourists, and can also be used for space research. These spheres will be moved slowly as they will change the angular velocity of the settlement due to the Conservation of Angular Momentum. Although the change is minimal, the spheres need to be moved slowly to restore the original rotation rate. All of the rotating and non-rotating components will be joined together using an elaborate system of magnetic bearings. Figure 2.2 – Diagram of the Torus For providing natural lighting to the interior space of each torii, a light-seeking reflective mirror would be placed on the central shaft between Torus 1 and the Communications Sphere. The mirror will be made out of the organic polymers Mylar and Kynar. Artificial gravity will be created by rotating Aresam around its axis. This will produce centrifugal force normal to the floor. This centrifugal force will be responsible for generating artificial gravity. The magnitude of artificial gravity was taken equal to normal Earth gravity, i.e. 9.8m/s2, so as to simulate Earth-like conditions. All the regions except the storage areas, which require no human activity, will be pressurized. Calculations: As mentioned before, storage and agriculture will take place in the Torus 1. One person requires 155.2 m2 of area (from NASA 1975 Summer Study). Subtracting the area requirements for storage and -Page 3- Northdonning Heedwell Aresam .::. Mars Space Settlement agriculture a figure of 89.2 m2 is obtained per person for the residential torus and 66 m 2 for the agriculture torus. Thus the total area in the residential torus will be 15000 * 89.2 which gives 1,338,000 m2. Similarly, the agricultural torus requires (15,000 * 66) = 990,000 m2. Taking into account the rotating motion of the settlement, we must determine the radius of both the torii for which the simulated gravitational constant along the residential area is optimum (g = 9.81 m/s2). 2 Acceleration = ω R = 4π 2 / T2 * R (Where ω is the Angular Velocity, T is the time period of rotation) Hence R = gT2 / 4π 2 Considering the reaction of the human body to different angular velocities, and taking into account the artificial gravity, a rotation time period of 60 seconds is most suitable for the space colony. Hence the orbital velocity of our settlement = 0.104 rad/s, R = 9.81 * 60 * 60 / (4 * 9.85) = 894.56 m The value of the major radius will be same for both the torii. For the residential torus, Area required = 1,338,000 m2 = 4π * r * R Hence r = 119 m (where r is the minor radius of the torus) Torus Volume = π2 * r2 * R = 125,026,808 m3 Residential and Agricultural Cylinders: Height (h) = 60m Radius (r) = 110m Volume = π r2 (h + 4r/3) = 7,856,076 m3 Total Surface Area = 2π r (2r + h) = 193,522.1 m2 Communication Sphere: Radius (r) = 60 m Volume = 4/3 π r3 = 904,320 m3 Surface area = 4π r2 = 45,257.14 m2 Central Shaft: Length of the Central Shaft =1,800 m Radius of the Central Shaft = 8.5 m Volume of the Central Shaft (π r2 h) = 408,357 m3 Surface Area of the Central Shaft (2π r h) = 96,084.2 m2 Figure 2.3 – Torus (Not to Scale) Docking Cylinder with Hemispherical Cap at the Top Total Inner Radius (r) = 200 m Cylindrical Height (h) = 250 m Total Surface Area of the Docking Station= 2 π r (h + r) = 565,200 m2 Total Volume of the Docking System = 48,146,666.667 m3 Total Surface Area of Aresam = 3,228,063.44 m2 Total Volume of Aresam = 307,369,035.7 m3 Total Surface Area with Zero/Low-Gravity = 900,063.4 m2 Total Volume with Zero/Low-Gravity = 57,315,419.67 m3 It is seen that the total surface area and total volume of all the low gravity zones works out to be 27.9% and 18.6 % of the total surface area and total volume respectively of Aresam settlement. -Page 4- Northdonning Heedwell Aresam .::. Mars Space Settlement 2.1.2 DOCKING SYSTEMS AND FUEL STORAGE: Our non-rotating cylindrical docking system has adequate provisions for at least 10 cargo ships and 5 passenger ships simultaneously. It will also contain a “repair bay” for long term docking of ships requiring emergency repair. The fuel stored on Aresam is mainly CO2 (for MagBeam propulsion), Hydrazine and Nitrogen-Tetra Oxide and hydrogen. All fuels will be stored in liquid state. Inflammable cargo and fuel will be kept away from the docking system to reduce the risk of fires and similar accidents. There will be one passenger terminal with a capacity of 1000 to accommodate passenger carriers. Aresam will offer facilities for transfer of cargo, fuel and provisions to passenger and cargo ships. During the main docking approach, radar systems on Aresam will guide the ship in to the docking station with the help of magnetic fields. Aresam docking ports also feature retractable arms that dock with the ship at considerable distances and then pull the ships in. This will serve as an emergency measure in case the magnetic docking fails or is unable to perform its function. All ships while docked will be controlled by the Central Control Unit (CCU). 2.1.3 SHIELDING A significant difficulty for manned missions outside the Earth’s magnetosphere is the hazard of crew exposure to particulate radiation in colonization-related activities and Mars-based mining and manufacturing etc. In order to overcome this problem, both active and passive shielding will be employed at Aresam. A. Active Shielding: Electromagnetic shielding is the most convenient way of protecting against ionizing radiation. The magnetic shield is based on the fact that a charged particle’s trajectory in magnetic field is curved. When a particle enters a high magnetic field region, its trajectory will be curved away from the region that needs protection. Figure 2.4 – The Particles’ Trajectory If we know the intensity of magnetic field (B), mass (m), speed (s) and the charge (q) of the particle, it is possible to determine the “Lawrence Force“(f) and the radius of the particle’s Circular Trajectory (R). F=qv*b Fcf = m v2 / r Therefore, M v2 / r = q v * b R=mv/Bq (Where r is the radius of the magnetic field) Figure 2.5 – Coil Diagram -Page 5- For maintaining a magnetic field around the settlement, a series of close wound bobbins placed on the exterior margins of the torus will be used, powered by photovoltaic panels. The inductance of a single layer of coil can be determined according to the Wheeler Formula: Northdonning Heedwell Aresam .::. Mars Space Settlement L = d2 n2 /1 + 0.45d The amperage required to maximize the efficiency of the magnetic field can also be resolved by: E0 = 622 Wm-2 (E0 = Solar Power per m2) R0 = m v / q b B = (µ0 * µr * n * I) / L µSUPER ALLOYS = 106 H / M B = (µn * I) / 2R (R0 = Radius of the Magnetic Field) (µ0 = 4π * 10-7H/M) Taking into account that the coils will be entirely exposed to the ionizing radiations, the radius of the coil (R0) needs to be half of its length: R0 = L / 2 S = L2 = 0.25 m2 = Surface of the Coil to face the sun P = E S ή = 622 * 0.25 * 0.30 = 52 (p= Power Generated on a Coil), (ή = Efficiency of the Panel) B = m v * q ro = (µ0 * µr * n * I) / L (n = No. of Turns = 104) I = m * v * l / q * r0 * µ0 * µr * n For a proton particle (which is the most common particle in solar flares), (q = 1.67 * 10-19 c) 7 Velocity = 2 * 10 m/s I= 1.6 * 10-27 * 2 * 107 * 0.5 * 107 / 1.6 * 10-19 * O.5 * 4π * 10-7 * 106 * 104 I = 159.2 A The calculated amperage is possible to generate. The electromagnetic field created by the system of coils will function very efficiently but there will be points found in less intense electromagnetic field between the coils. However, they will not raise any problems because of their symmetric repartition. Active shielding has many advantages over its passive counterpart. Active shielding is more predictable and it can be controlled accurately. In addition, it costs less than passive shielding. Thus, active shielding does not pose any threat to the sensitive electrical circuitry prevalent around it, and to human health because the intensity of the magnetic field is not very high. B. Passive Shielding: A bit of passive shielding will also be required to protect against the deadly Galactic Cosmic Rays (GCR). The following will be used to ensure that the residents of Aresam would be protected against the harmful radiations: An organic polymer, Zylon will provide the majority of the strength. Zylon is a new high performance fibre, which has superior tensile strength and modulus compared to other fibres like Vectran and Kevlar. It also has outstanding flame resistance and thermal stability. The carbon required for it, can easily be mined from Phobos and Deimos Aluminium and titanium alloys will also be used as they are highly effective in shielding against the deadly cosmic radiation and debris penetration, they also offer tremendous strength and support to the overall structure Sonex polyurethane is a low weight open cell foam , the foam support is hollowed out with cores spread out to reduce the shielding mass by 50% .The foam slows down the shattered particles and decreases the overall weight. -Page 6- Northdonning Heedwell Aresam .::.

All others were multiplied by 15,000 (14000 for the residents and 1000 Extra). 2.3 CONSTRUCTION SEQUENCE Phase 1 Initially, payload consisting of parts to assemble a MagBeam propulsion Station (see Section 3.3.1) will be sent to Mars using the Tether System. It will be set up in orbit at about an altitude of 11,000 Km from the surface of Mars. At the same time, a MagBeam Station will be setup at High Earth Orbit. Simultaneously, mining will start at the Moon through the Alaskol and Balderol bases. The construction robots (see Section 5.0) will then be transported to the Martian Orbit using the newly installed MagBeam. Meanwhile, scientists will be posted on Bellevistat and Alexandriat from where they will constantly monitor the activities of the Robots working in the Martian orbit. The work of mining will be done by Robots on places including: Phobos and Deimos (Martian Moons) Mars Moon (Earth Moon). The construction materials will be stored in a network of inflatable structures with solar arrays (for power) that will be transported through the Tether System. Phase 2 The construction of Aresam will actually begin in this phase. The Central Shaft and the structures attached to it will be built before all other structures. Construction will start with the docking system and proceed upwards through the Cylinders to the Communications Sphere. The mirror will also be constructed during this phase. Phase 3 This phase will be the longest, as it involves the simultaneous construction of the two torii. It will start with the construction of the spokes from the two cylinders reaching out to the two torii modules. After the spokes of both torii are constructed, the modules will be built. Due to the massive size of the torii, this -Page 7- Northdonning Heedwell Aresam .::. Mars Space Settlement phase will involve extensive construction (most of which will be automated) and some human involvement. Phase 4 This phase involves setting up the internal systems and construction of inner structures and buildings. After completion of construction, this phase will also involve testing and inspection of all systems and subsystems. Finally, the made-to-order structures and interior designs will be made. This phase will probably have the maximum human involvement out of all four. 2.4 MARS ORBIT INFRASTRUCTURE EXPANSION Aresam will have adequate infrastructure to meet needs for increased cargo and passenger traffic when major settlement are established on mars .It will be equipped with the state of the art technologies to set up heavy manufacturing centers for space infrastructure like interplanetary transport Some of the various transportation systems apt for these are as follows: MAGBEAM: MagBeam station can be set up at different areas in the solar system, which can provide transport of cargo and mined minerals from other planets to Mars. Figure 2.6 – Reusable Launch Vehicle (RLV) REUSABLE LAUNCH VEHICLE (RLV): The RLV used on Mars will be X-33 Venture Star. This RLV has Aero-Spike engines which will increase efficiency and reduce the launch cost. Venture Star is ideal for transport of payload of minerals from surface to orbit. UNMANNED SPACE VEHICLES: For atmospheric resonance, small sized robotic planes will be launched from the ground which will monitor the atmosphere Figure 2.7 – Unmanned Robotic Plane and can come back when required with the required information. It is considered apt for mineral mapping, weather forecasting etc. Aresam can serve as a commercial manufacturing centre which will help the foundation company to earn profits. MARS RECON: This vehicle is considered ideal to facilitate passenger transport in the harsh conditions of Mars. Figure 2.8 – Mars Recon -Page 8- Northdonning Heedwell Operations and Infrastructure Aresam .::. Mars Space Settlement 3.0 OPERATIONS AND INFRASTRUCTURE 3.1 CONSTRUCTION MATERIAL SOURCES 3.1.1 LOCATION Aresam will be placed in a polar orbit around Mars having an altitude of 11000 km; this location will help us in easy access to both the natural satellites of Mars and the planet itself. Statistics are: Time Period of Revolution = 52321.90795 s. Orbital Inclination = 25.19 º (With Respect to the axis of Mars and towards the Sun). Aresam requires continuous sunlight onto it so as to facilitate power generation, crop Production etc. It is for this reason that such an orbital inclination has been chosen, so as to receive sunlight without any interruption. In case of any transit or non-availability of sunlight we will use artificial light to produce crops. Materials and substances can be easily transported within the Mars-Phobos-Aresam-Diemos System and of course, to Earth. Hence we believe that this location will be perfect to assist us in both economical and Technological benefits.

Mars Space Settlement 3.2 COMMUNITY INFRASTRUCTURE 3.2.1 FOOD PRODUCTION Aresam will provide a self-sufficient environment for people living there with the use of hydroponics--soil less agriculture. Most commonly, hydroponics cultivate plants in nutrient-rich solution. It is an advantageous method of growing crops both for domestic and commercial use. We will take into account all the nutritional requirement of the people living on Aresam. The following table illustrates the annual requirement of 15,000 people: S. No Crops Annual requirement Annual yield (per m. sq.) 1. 2. 3. 4. 5. 6. 7. 8. Rice Wheat Vegetables Fruits Potatoes Tomatoes Corn Soybeans 6,84,375 12,31,875 37,61,325 25,73,250 9,47,175 9,05,565 3,04,167 8,34,850 255.52 226.3 684.375 561.38 912.5 985.5 273.5 283.0 Land requirement (m. sq.) 2678.36 5443.54 5496.00 4583.79 1038.00 918.88 1111.11 2950.00 Light is very essential for the growth of a plant. In case of indoor agriculture, artificial light is used, through “gro-lights”, metal halide lamps etc. At least half a day long direct sunlight is essential for the growth. Nutrient solution is very important for crops. Its pH will be maintained between 5 to 6.5 and all the basic minerals like, phosphorus, potassium, calcium, nitrogen source, iron, zinc, copper, magnesium, chlorine, sulphur, etc., will be present in it and all the utilized nutrient solution will be recycled for its reuse. Plants will be utilizing CO2 to produce food by photosynthesis. They will exhale oxygen in this process, which is essential for life support on Aresam. Temperature and humidity will be maintained by condensing heat exchanger (see Section 3.2.5D). Another consideration for hydroponics agriculture is air circulation. This prevents fungal diseases and allows the plants to draw out the necessary carbon dioxide they require (see Section 3.2.5E). Aggregate systems use some form of inert material to support and surround plant roots. The most common materials used are rockwool, clay pebbles and gravel, perlite, vermiculite, sand, or foam chips. The media provides plant support, allows good air penetration to the roots, and yet retains a thin layer of nutrients and water around the roots. One of the most common systems using an aggregate media is the Flood and Drain Method. A water-holding container is filled with the aggregates. The container is flooded periodically with the nutrient solution. The solution is drained back into the nutrient reservoir through a valve at the bottom of the container. Total area required for poultry will be 1, 57,890 m2. Taking into account the requirement of nonvegetarians living on Aresam, the following animals will be kept in poultry: A. Animal Products: ANIMAL Fish Chickens Rabbit Cattle -Page 10- NO. /person 2.6 6.2 2.8 1.5 AREA/ANIMAL(m2) 0.1 0.13 0.4 4 Total area (m2) 39000 12090 16800 90000 Northdonning Heedwell Aresam .::. Mars Space Settlement After harvesting of crops and slaughtering of livestock, it will be sent to the Hygienic Food Processing Unit (HFPU) for packaging and canning (see section 3.2.1C). B. Storage System on Aresam: In case of any crop failure or low availability Aresam will be providing a backup of 3 months, so that we have enough amount of food till it can be imported from Earth. It will be installed within the agricultural torus. The storage area of Aresam will be equipped with temperature and humidity control devices. This device will force warm stale air out and CO2 rich air will be drawn in through the vents. This device will be cycled by a timer or will be connected with a thermostat or environment control device. Ideally, the storage system should have humidity around 15% or less, otherwise there will be chances of microbial growth. The stores will also be installed with pest control devices. Sunlight also has to be adequate in the storage area. There will be separate compartments for dairy product and grain to be kept for farm animals. Ships reaching Aresam will require provision for food and water. Aresam will provide all the facilities sufficient for year-long voyages for one cargo ship per week with a 20-person crew and one 500passeger ship every three months. C. Processing, Packaging and Supply of Food Items: All the food items must be processed before they are supplied to different modules on Aresam. They will be sent to the Hygienic Food Processing Unit where packaging of food will be done in following steps: Drying: In this step all the water content from the food item will be drawn out, which will make its storage much easier and minimize the chances of bacterial growth Refrigeration: The food will be kept in vacuum packets in the refrigerator to reduce the chances of contamination Pasteurization: It will be done to make the milk and milk products safe for human consumption by destroying all the bacteria that may be harmful to health (pathogens) and also to increase their life. It includes heating the products at specific temperatures (around 336 K) Packaging: Its packaging has to be done hygienically keeping in mind the psychological concerns of the people. It will be packed in reusable containers (hydrated food container) Supply: After processing and packaging, the food will be supplied to the super markets to reach its consumer. 3.2.2 ELECTRICAL POWER GENERATION AND DISTRIBUTION Electricity on Aresam as well as the Surface Research Facility (SRF) will be generated from Photovoltaic (PV) systems Photovoltaic Systems which produce zero emissions, are modular, and can produce energy anywhere the sun shines. Such systems will be the main source of electric energy on Aresam. The Power Generation System (nicknamed “Helios”) will have enough backup power storage to allow smooth functioning of the entire settlement without any compromise. The amounts of electricity that can be produced depend on the following: The incident solar irradiation or the Solar Constant (Amount of solar energy incident per unit area and time) Efficiency of the solar cell used Surface area of the solar array or number of solar cells used. The solar constant is about 622 Wm-2 on the Mars orbit compared to 1400 Wm-2 of Earth. A. Power Sources: Basic Working of Photovoltaic Systems Photovoltaic (PV) cells are made of special materials called semiconductors such as silicon. Basically, when light strikes the cell, a certain portion of it is absorbed within the semiconductor material. This means that the energy of the absorbed light is transferred to the semiconductor. The energy energizes electrons loose, allowing them to flow freely. PV cells also all have one or more electric fields that act to force electrons freed by light absorption to flow in a certain direction. This flow of electrons is a current, -Page 11- Northdonning Heedwell Aresam .::. Mars Space Settlement and by placing metal contacts on the top and bottom of the PV cell, we can draw that current off to use externally. There are many technologies and designs of PV cells. We have decided to use the most viable option, i.e. GALLIUM ARSENIDE (GaAs). Gallium Arsenide (GaAs) is a compound semiconductor: a mixture of two elements, gallium (Ga) and arsenic (As). GaAs is especially suitable for use in multi-junction and high-efficiency solar cells for several reasons: The GaAs band gap is 1.43 eV, nearly ideal for single-junction solar cells GaAs has absorptivity so high that it requires a cell only a few microns thick to absorb sunlight. (Crystalline silicon requires a layer 100 microns or more in thickness) Unlike silicon cells, GaAs cells are relatively insensitive to heat. (Cell temperatures can often be quite high, especially in concentrator applications) Alloys made from GaAs using aluminium, phosphorus, or indium Characteristics complementary to those of gallium arsenide, allowing great flexibility in cell design GaAs is very resistant to radiation damage. This, along with its high efficiency, makes GaAs very desirable for space applications. One of the greatest advantages of gallium arsenide and its alloys as PV cell materials is the wide range of design options possible. A cell with a GaAs base can have several layers of slightly different compositions that allow a cell designer to precisely control the Name Gallium Arsenide generation and collection of electrons and holes Chemical Formula GaAs (To accomplish the same thing, silicon cells Melting Point at SP 1516K 2 have been limited to variations in the level of Electron Mobility at 300K 0.92m /V·s 2 doping). The largest barrier to the success of Hole Mobility at 300K 0.04m /V·s GaAs cells for terrestrial use has been the Efficiency 25%-30% purportedly high cost of a single-crystal GaAs substrate. But GaAs cells are used primarily in concentrator systems. The typical concentrator cell is approximately 0.25 cm2 in area and can produce ample power under high concentrations. Thus using GaAs solar cells in concentrator systems would make the cost low enough to make them cells competitive, assuming that module efficiencies can reach between 25% and 30% and that the cost of the rest of the system can be reduced. B. Energy Storage: Figure 3.2 - Schematic Diagram of the Working of a Lithium Ion Polymer Type Battery -Page 12- Northdonning Heedwell Aresam .::. Mars Space Settlement On Aresam we will be using Lithium-Ion Polymer Battery (Super lithium polymer) for power storage. NiCad (Nickel Cadmium) type of batteries is not an option because of the expensive raw materials and the environmentally risky Cadmium. Cathodes in solid-polymer Li-ion cells use an inexpensive metal oxide. More significantly every component of a solid-polymer Li-ion cell can be fabricated in rolled-sheet form to support exceptionally cost-effective, high-speed, high-volume battery production. Electrodes, electrolyte, and foil packaging are sandwiched together on continuous-feed rolls into finished batteries in one smooth process. Some of its advantages are: The estimated cost of Solid-polymer Li-ion batteries is about $1 to $2/WH (Once mass produced. As a point of reference, NiCad batteries, with five decades of manufacturing improvements, cost slightly less than $1/WH). The basic internal structure of a solid-polymer cell can be configured to virtually any size Solid-polymer Li-ion cells offer cost-effective materials and construction, which have been demonstrated safety under abuse conditions, environmental acceptability, and virtually limitless flexibility. Every component of the solid-polymer Li-ion system is, as the name suggests, solid, including the electrolyte. There is no liquid that has to be contained by hermetically sealed cell packaging. An ultra-thin laminated foil material, instead of a rigid metal can, can be thus used to house each cell The width and length of solid-polymer Li-ion cells are as flexible as their thickness. Cells can be configured in virtually any size, making solid-polymer Li-ion a strong candidate for electric vehicles and other large-cell applications like ours. This size flexibility of solid-polymer batteries supports maximum energy efficiency within a particular battery cavity. In terms of cost, the solidpolymer Li-ion system also promises advantages This technology is very promising and we believe that by the time the construction of Aresam begins this technology will be much cheaper and we may even have better options. C. Requirement of Inverters: The energy produced from solar energy using Photovoltaic cells is DC (direct current). DC can’t be used for all types of appliances and applications. Thus an inverter is essential for converting DC to AC (Alternate Current). Inverter efficiency is a very important part of the system. The efficiency of an inverter has to do with how well it converts the DC voltage into AC. This usually ranges from 85% to 95%, with 90% being about average. Thus we will be using a high capacity inverter working on “True Sine” wave form. D. Estimated Power Generated: Solar constant on Earth’s orbit = 1400 W/m2 approx. Solar Constant on Mars (S) = 622 W/m2 approx. Calculations: Sun-Mars distance = d MS = 225 × 10 6 km Sun-Earth distance= d MS = 149.4 x 106 km Total power received on a sphere with radius d ES = 4πd ES × 1400 W . 2 At the distance of Mars, the same power is received on a sphere with radius area = 4πd MS d MS = 225 × 10 6 km and 2 Let PM be the power received per square metre at the distance of Mars, then -Page 13- Northdonning Heedwell Aresam .::. Mars Space Settlement 4πd ES × 1400 = 4πd MS × PM 2 2 and finally: ⎛d PM = 1400 × ⎜⎜ ES ⎝ d MS 2 ⎞ ⎟⎟ = 622 Wm − 2 ⎠ Area of Solar Cell (N) = 1,130,140 m2 Efficiency of Solar Panel = 30% Solar Energy Incident = S x N =603,108,800 W (603.1MW) Power Produced = 30% of (S x N) = 210,932,640 W (210.9MW) Approximate Efficiency of Inverter = 90% Power after Conversion from DC to AC by the Inverter = 90% of 210,932,640 W = 200,386,008 W (200.3 MW) 3.2.3 COMMUNICATION SYSTEMS A. Internal Communication: Internal communication is a pre-condition for the smooth functioning of any space settlement. Aresam requires a fast, reliable and high-bandwidth communication infrastructure to facilitate the various operations taking place within its torii. Keeping these factors in mind, the communications infrastructure of Aresam will include both wired and wireless communication systems: Fiber Optic Backbone (FOB): The core of the wired communication network will be supported by Fiber Optic Cables. These are efficient and fast, and no data loss occurs at any stage. The Fiber Optic Network will provide an overall 50 tbps of bandwidth. The Main Server and Sub-Terminals will all communicate with the Fibres Optic Network, and any other operations, whether business or otherwise, that require extra bandwidth will be provided with an exclusive Fibres Optic Connection. Wireless Local Area Network (WLAN) based on WiMAX Technology: WiMAX (Worldwide Interoperability for Microwave Access) is the IEEE 802.16 standards-based wireless technology that provides wireless communication facilities at ranges up to 50 km. Aresam will be entirely WiMAX enabled, and any device with WiMAX capability will be able to connect to the WLAN. The residents of Aresam will all be given Wireless Client Adapters on arrival to allow wireless connectivity. The advantage of WiMAX is that it covers a couple of different frequency ranges, namely 10GHz to 60GHz and 2GHz to 11 GHz. WiMAX offers the flexibility to support a variety of data transmitting rates on a single channel that can support thousands of users. Using multiple-point access systems (i.e. connecting more than one terminal is supported by a single network termination), the total bandwidth will amount to about 360 mbps. A Central WiMAX Tower will be installed in the Communications Sphere, and it will provide coverage to the station, along with WiMAX routers. “Hotspots” will be generated through access points on the ceilings of the settlement at regular intervals to create an uninterrupted communication net about Aresam. These access points will be connected to each other using the FOB. Both FOB and WLAN will be based on IPv6 (Internet Protocol Version 6) Technology. B. External Communication: Communication between our planet Earth and Mars, 75 million kilometres away, is a gruelling challenge; even light takes 4 minutes to reach from Earth to Mars. In other words, communication between Earth and Mars will take a minimum of 8 minutes, as nothing is capable of travelling faster than that. Aresam will communicate with Earth using the latest in Laser technology, which would travel at the same speed as light. The entire communication system is called “Twilight”. Advantages include higher data rates, low probability of intercept, lower power requirements, smaller packaging, and lower frequency allocation requirements. All communications will take place through two laser communications equipped satellites, Twilight I and Twilight II designed specifically for use on Aresam. The satellites will be installed with Laser transmitters -Page 14- Northdonning Heedwell Aresam .::. Mars Space Settlement and receivers, as well as radio communication capabilities and an emergency transmission device, in case of emergency. The device will turn itself on and start sending signals to Earth and Aresam simultaneously, if no communication is made between it and Aresam for a period of 8 hours. The satellites will be put in orbit around the sun, between the orbits of Mars and Earth. They will have small thrusters installed on them, in case a direction change is necessary. They will maintain a constant connection with both Earth and Aresam. The main power source will be the Solar Panels installed on both of them. The Communications Sphere at the head of Aresam will be installed with two Laser transmitters and receivers, and each pair will communicate with either Twilight I or Twilight II. The incoming Laser signals will be received via Telescope and signals will be sent through specially designed Laser Transmitters with Location Tracking Technology, so that the signals that are sent always reach the satellites directly. Twilight I and Twilight II will both have the same specifications, albeit a few size modifications. Once Twilight I and Twilight II receive signals from Aresam, they will further transmit the signals to the Tracking and Data Relay Satellite System (TDRSS). This system will include a number of relay satellites placed at strategic points in the Earth-Moon system including the Lagrangian points and the orbits of Moon and Earth. There will not be a continuous connection with Earth, as it is prevented by many factors including power and orbital velocities. Therefore, there will be transmissions after every hour after the last transmission. The duration of the transmission will be twice the time required for the first transmission, i.e. the signal sent and received. During this Transmission Period, all necessary communication with Earth will be made. For example, if an e-mail is to be sent to Figure 3.3 – Laser Motor for Laser Communication Earth, it will be stored on the Aresam computers until Transmission Period, during which time it will be transmitted to Earth. Communication through radio frequency will also be possible through the above-mentioned satellites. 3.2.4 INTERNAL TRANSPORTATION The Internal Transport System of Aresam (nicknamed “Mercury”), consists of the following: An efficient Mass Transit System consisting of the Monorail System A Personal Transport System An Elevator System. A. Monorail: Aresam’s mass transit system consists primarily of a Monorail System which runs throughout the residential torus and to the storage facility in the agricultural torus. The Monorail consists of a dedicated line which runs parallel to the Central road that covers the entire circumference and is thus called “the Halo”. The Halo is connected to all roads in the residential torus. The Monorail will typically be deployed adjacent to the sidewalk, and be computer controlled with an option of manual override. -Page 15- Northdonning Heedwell Aresam .::. Mars Space Settlement There will be 7 Elevated Stations on Aresam with access points for the handicapped as well. There will be 8 trams running around the settlement at one time during the peak hours. The number of trams required will be judged by the number of people entering the Monorail Station and the closest SCU will inform the SCU on Module 4 (the SCU that controls the Monorail System; see Section 5.3.1) to increase or decrease the number of Trams running accordingly. The average speed will be around 30 Km/hr, i.e., around 8.3 m/s The number of stations is 7 The circumference of the Torus = 2 π r = 2 x 3.14 x 894.5 = 5617.5 m This Implies the Average Distance between Two Stations = 802.5 m This Implies that the Time Taken to Traverse the Distance between Two Stations = 802.5 / 8.3 = 96.7 s Rounding it off, we get 1 ½ minutes. B. Standard Personal Transport: For providing efficient means of providing personal transport to people Aresam will offer the following options: 1. Segways to provide assistance to pedestrians with their enhanced stability 2. A range of “Drive clean” cars to choose from: A four seater running on fuel cells which will not require charging and have a refuelling time of approximately 3 to 5 minutes A two seater running only on electricity having an optional 6 to12 Volt Lead Acid Battery with a recharge time of 6 to 8 hours A single seater running on a 84V battery having a recharge time of 3 to 4 hours and a driving range of 50 miles per charge. It will be able to switch between hi-speed and lowspeed modes. These vehicles have virtually zero emission levels and will be able to go from 50 to 100 miles on a single charge. 1. They will be based on the Honda FCX Concept Car and Toyota PM which use a hydrogen fuel cell and have already been introduced 2. ZEV or Zero Emission Vehicles, as defined by California State Law, emit 0% CO, Hydrocarbons and NO2. C. Elevator System: As the elevators will be required to move both horizontally and vertically through the various G-Levels, the standard elevators found in many building today were not considered practical. As such, magnetic levitation has been chosen as it has several advantages over conventional roped elevators. The spokes have a diameter of 10 m wherein: 2m – Human Elevator Shaft 4.5m – Cargo Elevator Shaft 0.5m – Radial Spokes Walls 0.3m – Internal Separation Wall 1. Cargo Elevators: Cargo elevators will mainly cater to the demands of transporting cargo for the agricultural cum storage torus to the residential torus to meet storage needs and other purposes. These will be 2.95 m wide, with a length of the 5m and a separation of 2.5 cm from each end for the functioning of magnetic levitating tracks 2. Human Elevators: Human Elevators, as the name suggests, will mainly be used for transportation of people between torii. Having a length of 2.5m and a width of 1.9m, they will have a separation of 5cm from each end for the functioning of the magnetic levitation tracks. In case of an emergency -Page 16- Northdonning Heedwell Aresam .::. Mars Space Settlement involving the failure of the magnetic levitation track, the callipers attached to the elevators will immediately hook to the walls, thereby preventing a fall. 3.2.5 ATMOSPHERE, CLIMATE AND WEATHER CONTROL A. Atmosphere on Aresam: A sustainable atmosphere has to be created on Aresam which will be similar to that of Earth, comprising of 78% Nitrogen, 21% Oxygen and 1% other gases. NASA studies demonstrate that the optimum temperature for good life development is 298K (25 degree Celsius) and adequate relative humidity would be 40-70%. B. Carbon Dioxide Elimination and Oxygen Generation: Chemical gases, which can also be produced by humans, must be carefully filtered from the air. The climatic control system of Aresam (nicknamed “Blizzard”) will be equipped with a monitor to check the levels of carbon dioxide and oxygen. Plants will be taking all the CO2 exhaled by humans, for the process of photosynthesis. Excess of CO2 can be used to produce carbon or methane by reacting it with hydrogen at high temperature, which can be used elsewhere. 2CO2 + 4H2 Or CO2 + 4H2 → → 2C + CH4 + 4H2O (Bosch reaction) 2H2O + Energy Artificial means of generating O2 mostly involve the electrolysis of water, electrolysis of water-vapour, or electrolysis of CO2. C. Climatic Features: For psychological concerns etc., our environment should be similar to that of Earth. In that case we will be creating artificial rain. Basically two structural parts will be requisite for generating artificial rain. The first part is the spraying tube located on ceiling of Aresam. The second structural part is the water tank which will be supplying water under pressure. On the surface, the rainwater will be recycled and used after it seeps to the drains with special filters to prevent any contamination. Temperature Control 40 35 Temperature 30 25 20 15 10 5 be r D ec em be r N ov em ob e O ct m be pt e Se r r t gu s Au Ju ly Ju ne ay M ril Ap h ar c M ry br ua Fe Ja nu ar y 0 Month -Page 17- Northdonning Heedwell Aresam .::. Mars Space Settlement D. Temperature and Humidity Control: Blizzard will also prevent overheating of Aresam. Condensing Heat Exchangers (CHX) will be widely used to remove moisture and heat at the same time from the atmosphere of Aresam. When air will be passed through it, all the unwanted particles will get filtered off. Then the air will be cooled below its dew point and thus resulting in forming water-vapours. Water-vapours then condense and will be carried by the airflow to the outlet where it will leave the main stream of air. The heated coolant will then dump its heat into space via the radiators. All the condensed water will be purified and then used as tap water or will be fed into the agricultural torus. Aresam will also be equipped with sensors to sense any kind of sudden change in temperature and humidity. E. Ventilation: A good ventilation system will have to be maintained on Aresam so that all the oxygen present on it gets replenished constantly and the heat escapes. This will help in creating the isolated and closed cycle that we are trying to maintain. It will also help in generating a minimum wind velocity on the settlement. All the exhausted air will be replaced by fresh air. A good ventilation system is also important for cultivation as it prevents fungal growth and helps the plants to draw out CO2. The wind velocity is expected to be of the order of 0.08 m/s. Due to generation of pseudo-gravity via the spinning of the colony, a natural convection current will result, driven by the temperature differential between the different areas of the torus. Computational Fluid Dynamics (CFD) will be used to determine requisite air flow. 3.2.6 WASTE MANAGEMENT ON ARESAM There has to be a closed cycle on Aresam where all the organic and inorganic waste will be collected from each module by the action of gravity. It will be taken to the Advanced Waste Recycle System (AWRS) because storing large amounts of waste on Aresam would use up a large amount of space and also increase weight. Everything must be extremely clean in space, because the risk of diseases increases as a result of confinement and exposure to microbes in microgravity. The cargo space of Aresam is limited; therefore waste products must be recycled as much as possible. Proper hygiene in space serves not only as a psychological comfort but as a safety precaution as well. A. Solid Waste Recovery: To some extent, chemicals, metals, glass can also be recovered, recycled, or reused safely and there is obvious economic incentive to do so. Materials that are recovered, recycled, or reused do not become a liability problem or a problem for the environment. Human waste primarily consists of faeces and urine, and the first step will be segregation and filtration of waste which can be achieved through sedimentation or centrifugation. The following processes will be used for minimizing the amount waste present on Aresam: Electrochemical Incineration Anaerobic or Aerobic Bioreactors. B. Composting of Organic Waste: The organic wastes of plants can be decomposed by micro-organisms, by sending them for composting in cylindrical vessels to convert them into humus. This way the humus can again be used as fertilizer for crops. C. Waste Treatment: To prevent microbial growth in waste, all the water present in the waste will be extracted by converting it into steam at very high temperature. At high temperature, this steam results in thermal killing of the microbes present in the waste. The water obtained will then be sent to the PWPU (see Section 3.2.7A). This way not only the volume of the waste is reduced, but the residue is also left in the dry state to promote long term stability. Fiber Absorbents (highly absorbent cellulose) product will be used to stabilize sludge for transportation and disposal (including incineration). -Page 18- Northdonning Heedwell Aresam .::. Mars Space Settlement 3.2.7 WATER MANAGEMENT Water is an indispensable part of life so both the torii will have an integrated water cycle. Initially, we will have to carry water with us as we won’t be able to find water supply in space. The recycling of water will be carried out at the earliest so as to ensure availability of water thereafter. Even the water recovered from the sludge process for waste water purification can be used as tap water, or it can be fed into the agricultural torus. A. Water Recovery: To recover the waste water, Sludge Process for Waste Water Recovery (SPWWR) is used, involving acidic coagulation process by effectively removing high polymer organic compounds that are not biologically decomposable. Then all the water is mixed with bacteria that digest all the degradable material present in it and in the final stage it is sent to disinfectant tank, where it is mixed with iodine. Thus, the water is fit to be used for domestic purposes. The waste water contains small silicon particles. This filtering separator will remove silicon particles in colloidal suspension and collect pure water. Further which, reverse osmosis will be done to make it fit for drinking. B. Water Storage: All the required water will be stored in the Central Storage Unit (CSU) of Aresam, where it will be kept until it is needed. This CSU will comprise of 30 storage tanks each having a capacity of 22355.4 litres (fulfilling the requirement of every five days). In case of fire or any other emergency, the water will be supplied from the CSU. C. Water Cycle: All the water gathered from perspiration (of humans or plants), humidity, urine, condensation etc. will be sent for processing in the pure water production unit of Aresam. All the water will be purified using equipments like de-aerators and evaporator. The water used in artificial rain will be collected from the drains and will be recovered in PWPU and will be transferred again in the spraying tube located at the ceiling. All the contaminated water will be sent to Sludge Process of Waste Water Recovery (SPWWR), so that all the unwanted pathogens can be removed from it. Comets and asteroids are mainly composed of water in the form of ice; they can also be a source of extracting water (For example, the asteroid “Ceres” in the Asteroid Belt). These celestial objects are very rare but even then we must not exclude them. D. Water Requirement: Water required per person per day = 50 litres Water required for 14,500 people per day = 725,000 litres. With 85-90% efficiency in water recovery by SPWWR (sludge process for waste water recovery), the amount water recovered is 652,500 litres and it will be supplied to the CSU again. 3.2.8 DAY AND NIGHT CYCLE Aresam will be located in the polar orbit so that the settlement does not transit under the shadow of mars. It will be receiving constant sunlight and will be covered by electrochromatic glass to maximize the light absorption. This process involves trapping of sunlight using ions in between the two layers of glasses. This provides light to the whole settlement for the desired time. A dark period is also required so that plants can initiate Dark Reaction. The following materials will be required for electro-chromatic glass cover: Glass panels Conducting electrochromatic layer (Tungsten Oxide) Electrolyte Ion storage. -Page 19- Northdonning Heedwell Aresam .::. Mars Space Settlement 3.3 SPACE INFRASTRUCTURE 3.3.1 EXTERNAL TRANSPORT SYSTEM A. Transportation from Earth to MagBeam Station: We will be using a combined cycle engine for propelling our space ship. A combined cycle engine is an all in one engine that combines a jet engine, a ramjet, a scramjet and a rocket engine on a single spacecraft. After reaching a height of 300000 feet, the spacecraft will deploy its payload which can be transported to the MagBeam station via the tether system. The spacecraft will dock with the MagBeam station. All the cargo will be stored at the MagBeam station and will be transported to Mars using the MagBeam. The Tether system will be used to transfer vehicle from Low Earth Orbit (LEO) to High Earth Orbit (HEO). B. Working of MagBeam Propulsion System: The NASA-tested system requires a separate power source at each end of the journey: one to accelerate the spacecraft at the start (in orbit around Earth) and another at the destination, to decelerate it (in orbit around Mars). The spacecraft simply coasts during the journey from planet to planet but can control its movement using small reaction thrusters onboard. The High Power Helicon (HPH) is a state-of-the-art electrode less plasma thrusters, which allows high power levels to be generated over long periods of time with little erosion of the system. The plasma is generated by high power radio frequency waves. As a result, HPH is substantially smaller than other plasma thrusters. The system can charge its batteries using solar power only. The spacecraft will need to have a deflector system to accept the energy from the HPH. This can be achieved by plasma magnet systems; plasma effects are used to make an initially large magnetic deflector. The system is self-focusing. The HPH, would fire a plasma beam at the target spacecraft for about four hours, giving it a boost of about 20 km/sec (12.4 miles/sec.) toward Mars. The spacecraft coasts to Mars, and when it reaches there another HPH in orbit around Mars fires a plasma beam at the spacecraft to slow it down. The spacecraft will dock with the space settlement and can store all its cargo at the cargo bay. C. Advantages of MagBeam Propulsion: The MagBeam transportation can only take place when Earth and Mars are close to each other. One power source will be used to power multiple craft (serially, not at the same time) when this period comes. The power source will use solar energy, resulting in additional cost savings -Page 20- Northdonning Heedwell Aresam .::. Mars Space Settlement Plasma propellants are accelerated to speeds an order of magnitude greater than those achieved by chemical rocket propellants, resulting in higher spacecraft velocities - at least 26,000 miles per hour As the trip time is shortened, many difficulties (like the quantity of consumables and the psychological effects on the astronauts) will be greatly eased. To boost a 10,000 kilogram spacecraft to Mars with MagBeam consumes about 7,000 kg of propellant (CO2). The savings with the more efficient MagBeam system are significant. When our payload has docked with the settlement it will transfer all its cargo to the cargo bay where it will be stored. For research, scientists may travel to the surface of mars using Reusable Launch Vehicle (RLV). The fuel used to drive the RLV’s will be hydrogen. The hydrogen brought to Mars can be recycled many times. Alternatively, the feedstock to the RWGS can be run with an excess of hydrogen, in which case the effluent from the RWGS will contain both CO and H2. Such a mixture is known as synthesis gas and is the ideal feedstock for making methanol, dimethyl ether, or higher hydrocarbons. 3.3.2 VEHICLE REQUIREMENTS Space Vehicle Purpose of Vehicle Flight of the Vehicle Vehicle Specifications Payload Flight per Year Cost ($/kg) Panzer Transport of payload Earth to LEO 880Kg 150 2,200 Beamer Transport of humans and essentials For travelling *HEO to Mars orbit Geared engine, Carries less of Oxygen Works on CO2, Top speed 20Km/s 1,723Kg 26 2,200 It can be reused; can carry max of 8 people.

Mars Space Settlement 3.4 MARSUV The MARSUV (MARS AREOLOGICAL RESEARCH SURFACE UTILITY VEHICLE) will be 25m long and 15m broad. It will have a Radar Unit for communication. A pair of robotic hands will be used for sample collection. A solar cell lined hull will provide us with the requisite electricity and power for mobility. A cockpit will be placed at the front of the UV which will act as a hub for communication, navigation and sensory functions, and will monitor all activities. Sensors will be placed all over the UV and will provide information on the surroundings to the central computer and its researcher’s. The living room and sleeping area will be placed just behind the cockpit. Figure 3.5 - MARSUV Design -Page 22- Northdonning Heedwell Aresam .::. Mars Space Settlement All rooms will be phonically insulated for providing privacy to the researchers. The MARSUV will also be equipped with a mini laboratory. There will be a storage area for food, water and clothing. The urine can be processed in the water filter unit placed at the rear of the UV. Four units of caterpillar wheels will be placed on the two units of UV which will be connected together using flexible connectors. The MARSUV will run on 500 HP electric motors. The motors will run on electric current which will be stored in Metal hydride batteries. The batteries will be charged using solar cells. Communication can be done by using radio waves at a frequency of 100 GHz. For cooling and heating, advanced AC’s will be used. Figure 3.6 – MARSUV Interior For More Images Visit Our Website: http://amityaresam.bravehost.com -Page 23- Northdonning Heedwell Human Factors Aresam .::. Mars Space Settlement 4.0 HUMAN FACTORS Aresam is designed to offer the best quality of life in the entire solar system. Hence, NH has planned to maintain traditional comforts of Earth on our settlement. All possible efforts have been made to ensure that the residents of Aresam enjoy quality standard of living, fine food and access to world class entertainment even in the dull environment of space. The residents of Aresam can feast their eyes on the spectacular views of Mars below through the communication sphere. Aresam would provide facilities for services that residents could expect in a comfortable sub-urban environment (e.g. education, housing, entertainment, medical, parks and recreational etc.), variety and quantity of consumable and other supplies, and public areas with open space and consideration of psychological factors. 4.1 URBAN ENVIRONMENT Several factors have to be considered before designing a good urban environment. The facilities provided would be education institution, kindergarten, primary and secondary schools, city hall, services, cinema, shopping malls, open public plaza, spa and resort, sports club and etc are provided. Besides, public amenities such as public toilets, playgrounds and sports centre will also be provided. Playgrounds would be located in the elementary schools for the convenience and exercise of the children. The area of the community central is deemed spacious for the comfort of the public. Lastly, there will be community markets and super markets as the means of distributing consumables to the residents. 4.1.2 EDUCATION In Aresam, the education of children will be of prime importance. All levels of education will be covered from the elementary school to professional institutions offered in a single university. There would be one school in our university having a lyceum, a gymnasium, library, extra-curricular activities, research centres and all other modern facilities. The university would offer graduation degree in all the upcoming fields. There would be regular workshops and interactive sessions for both students and teachers. Core classes on various subjects would be regularly conducted. The students will also be exposed to Zero-Gravity study and research. 4.1.3 ENTERTAINMENT On the space settlement, we will try to create living conditions similar to those on Earth; this includes forms of recreation and entertainment which will be provided in every module. We will build theatres, concert rooms, multiple theme parks, extreme sports etc. We can build a transport wall in the connector tubes specially designed for walking and admiring the space. Other motivating entertainment activities will be those placed in the zero gravity zone i.e. at the centre of the station, where colonists can swim in the zero gravity pool, sleep restful nights in a zero gravity hotel and partying in zero gravity discos. Organizing excursions in outer space has never been so energy efficient, thus making it cheaper, and so a very attractive way of relaxation. 4.1.4 HOSPITALS There will be one major hospital in Module 2 and minor medical facilities are available in every Module. The main Hospital named Aresam Medical Centre (ACM) will be able to accommodate 1000 patients at a time and a team of 150 very efficient doctors (the other 25 doctors will work in clinics affiliated directly to the AMC). Hospitals would be equipped with state of art technology to handle any kind of emergency. A few technologies for diagnosis of diseases during space travel and space settlements will be as follows: -Page 24- Northdonning Heedwell Aresam .::. Mars Space Settlement Blood Analyzer a toaster-sized centrifugal analyzing device can perform 80 to 100 chemical blood tests using a single drop of whole blood Cutting-edge pacemaker can change the heart rate in response to body activity. 4.1.5 Recreation Each module will be having one recreation centre like an amusement park, artificial lake, a multiplex, sports complex etc. Supermarkets and retail shops will be there for the distribution of consumables and other items. Hotels with casinos and spas will also be made for accommodating the visitors. Shopping complexes and multiplexes will be accessible to all. Aresam offers 270,000 m2 of open space, i.e., 10 m2 per person. An 18-hole golf course, swimming pool, tennis courts, basketball courts, multipurpose playgrounds and stadium will be there for the colonists. 4.1.6 PSYCHOLOGICAL CONCERNS The reason behind our concern for providing fit surrounding to cater human psychology is that the psychological effects of people living in an enclosed off-world habitat cannot be underestimated. Two of the most common syndromes are “Solipsism Syndrome” and “Shimanagashi Syndrome”. A. Solipsism Syndrome Some environments are conducive to the state of mind in which a person feels that everything is a dream and nothing is real. As a psychological state this is highly unpleasant. The sufferer becomes lonely and detached from reality. This eventually leads to chronic apathy and indifference. B. Shimanagashi Syndrome If a person from the mainland spends a few years on an isolated island, even though it may have large cities and modern conveniences, he/she feels a strange sense of isolation. They begin to feel left out and intellectually ostracized even though life on the island may be very comfortable. To alleviate such syndromes and stress the settlement will have many parks, sidewalks and some large artificial lakes with some special houseboats. 4.2 COMMUNITY DESIGN A community has character of ‘home’ and ‘sense of place’, local identity, respect for natural and artistic heritage, an understanding of the ‘urban grain’ or ‘townscape’, pedestrians and other modes of traffic, and utilities. Aresam will be designed to provide the inhabitants with an Earth like ambience. The residential tour will be divided into six modules each with an area of 401,400 m2. Each module has a central administrative unit, which serves as a terminal for the elevator shaft. It will also have police station, a judiciary, warehouses, a pharmacy and a passenger terminal. 4.2.1 RESIDENTIAL DESIGN Types of Houses Level 1 (Deluxe Houses) Level 2 (Medium Family Houses) Level 3 (Bachelors’ Houses) Population: 15,000 No. of houses: 10,920 Total residential area: 735,000 m2 Bachelor area: 367,500 m2 Family area: 183,750 m2 Deluxe area: 183,750 m2 -Page 25- Number of Houses 5,460 2,730 2,730 There will be three types of residential design, which are bungalows for the important visiting Dignitaries, residential apartments for the residing work force and one room apartments for bachelors. The bungalows consist of a master suite, three bedroom, two bathrooms, kitchen, balcony, and garage (these are only for CEO’s of the leading companies). The family homes consist of two bedrooms, a Northdonning Heedwell Aresam .::. Mars Space Settlement living room, kitchen, and bathroom. The one room apartment consists of one bedroom, kitchen and a bathroom (these are designed for single women and men). 4.2.2 OFFICES Aresam would have 15,000 m2 reserved for commercial offices. This area will be provided to companies to establish their branches in the settlement. The concerned companies may design and build their own offices using Northdonning Heedwell’s construction robots. The companies will receive a direct fibre optic link to the SCU (see 5.2.1) if they need dedicated bandwidth for their usage.

The suggested organization of the Aresam Governing Council is shown below: Governor Administration and Security (Selected Members / Bureaucrats) Policy Making and Regulation (Elected Members) Judicial System for Law and Order (Nominated Members) The governing council is formed through general elections every 5 years. The judicial system performs an advisory role towards legal and judicial aspects. The Aresam Court of Justice (ACJ) is the highest judicial authority functioning as the final court of appeal. There are Subordinate Courts to cater for law and order -Page 26- Northdonning Heedwell Aresam .::. Mars Space Settlement at the lower levels. In order to maintain peace and harmony manual and robotic police shall be deployed in the settlement. Use of weapons like laser guns, neutralizing sprays etc shall only be permitted in extreme cases. Any person accused of committing a crime at Aresam will be tried by the Aresam Court of Justice. During the trial and investigation, he/she shall remain under house arrest. If found guilty, the accused will be awarded suitable punishment by the Judicial System. 4.3.3 OCCUPATIONS Maintenance Construction Management Engineering Professional Services Robotics Commercial Business Entertainment Tourism Miscellaneous For More Images Visit Our Website: http://amityaresam.bravehost.com 4.3.4 BIOSUIT The BioSuit system provides enhanced astronaut Extra Vehicular Activity (EVA) locomotion and performance based on the concepts of a ‘second skin’ capability and can augment, bio mechanically and cybernetically, human performance. Bio-Suit relies on advances in fabrication and application of open cell foam, smart materials like advanced "muscle wire" technologies, and electro spin-lacing. The BioSuit uses smart materials that change their properties when electrically or thermally stimulated, like shape metal alloys, such as the nickel-titanium alloy, nitinol, used in cardiac stents. These alloys contract with great force when current is run through them and could, for example, be placed along a seam to pull the suit tight or along a limb to boost strength. Polymers, which can change from rubber-band-like material to stiff plastic in response to heat, could shrink to fit as they are warmed by the body. -Page 27- Figure 4.2 - BioSuit Northdonning Heedwell Aresam .::. Mars Space Settlement 4.4 ARCHITECTURAL THEME OF ARESAM Since Aresam will be one of Foundation Society’s latest settlements, it’s important that it too has its own architectural theme, which will be reflected in the buildings on Aresam and on the terrestrial base on Mars. It will constitute of a fusion of modern and ancient, Eastern and Western architectural features to complement its heterogeneous population. Some of the major structures like office buildings, city hall etc. will have these distinct features: Spiral cylindrical pillars Plano-concave roofs (Only specific area) Large archways with intricate carving or paintings (Only Specific Area) Wide foyers and Courtyards (Public building such as Government buildings) Geometrical Structures such as Cylindrical buildings Fusion of various facilities such as a mall and an aquarium. Abstract open-air stadium Designs Thus Aresam will make its mark as a new human frontier Figure 4.3 – Residential Apartments Figure 4.4 – Shopping Mall Figure 4.5 – Open-air Stadium -Page 28- Northdonning Heedwell Automation Design and Services Aresam .::. Mars Space Settlement 5. AUTOMATION DESIGN AND SERVICES Aresam is designed to require minimum human involvement in all its activities. To achieve such a status, the Automation Department of NH has developed what is called the Cargo Handling and Automation Operations System (CHAOS). The CHAOS works using the enormous computing Power of the Super Computers on Aresam and Separate Computers on individual Robots. The Robots will be wired with Real Time OS. Each robot will be programmed so that they could summon help from similar robots when a certain task proves too much for a single robot. All outer space robots will be coated with Polyethylene to protect them during solar flare activity to ensure continuous service. 5.1 CARGO HANDLING AND CONSTRUCTION AUTOMATION 5.1.1 CONSTRUCTION AUTOMATION Specification Height Weight Structural Materials Processor Operating System Robonaut 1.9m 182Kgs Mostly Aluminium with Zylon and Teflon padding to protect BAE Systems RAD900 (Radiation Hardened)133 MHz, 2.8 MIPS VxWorks (Real time OS) SCOUT 3m 200Kgs Mostly Nickel Titanium Alloy with Zylon and small amount of Lead for radiation protection.

BAE Systems RAD900 (Radiation Hardened)266 MHz, 2.8 MIPS VxWorks (Real time OS) The construction will be carried out by three very efficient robots viz. the Robonaut and the SCOUT for external construction and the Kronos for internal construction. The humanoid Robonaut will function as a multipurpose robot its bottom tip can be attached to various devices, thus giving it wider range of usage. The one shown in the figure is a free fling one that will be used for construction in space. Robonaut conceivably will anchor itself with all of the appropriate equipment required to perform an outer-space operation. It can open doors, use a drill, climb ladders and perform other manual tasks with its two arms and two hands. Its head comes with stereoscopic cameras and a light-emitting diode, or LED. Its hands will be powered by brushless motors and will be equipped with 150 sensors each. Post construction the Robonaut will be used for maintenance purposes after being fit into another “body”. The SCOUT construction and assembly robot can be tele-operated or manually operated by a construction worker. The SCOUT robots have a sufficient degree of freedom so as to allow them to carry out operations independently and also to sustain them during the time of construction of the settlement when no central computer is available to monitor their activities. Post construction its Vx Works operating system will ensure that SCOUT is used in the manufacturing and research Department. Figure 5.1 - Robonaut The Kronos, Aresam’s primary internal construction robot stands 3 meters tall, with adaptable hands which are outfitted with clamps. Its will be able to wire, use tools from its utility belt and be able to lift extreme loads with mechanical ease, true to its name. It will be modified post-construction for Maintenance purposes. The Kronos will move on its motor run wheels with cameras and sensors attached to its base for easy navigation.

Mars Space Settlement 5.1.2 CARGO HANDLING The CHAOS, as mentioned above, is the system that controls all automation devices on Aresam. Its main processing power comes from the “Evermind” computer located in the Central Computing Unit in the Core (Central Cylinder). The CHAOS consists of an Extensive Cargo Handling System which a hybrid of the Conveyor Belt System and the RFID system. The various steps that a metallic cargo container goes through once its offloaded from its ship are: Carried off the Ship by the CH1 and put onto the electromagnetic conveyor belt with the help of the CH2 which carries it off to the temporary storage area in the docking facility The container is “tagged” at the temporary storage facility from where it is transported to the Agricultural cum Storage Torus through the elevator shafts and sent to the designated storage areas(Freezer, Reefer, bulk storage) with the help of the RFID tagging and a second robot CH 2 When required the “tagged” cargo is redistributed to its respective areas with the help of the Monorail system. 5.2 MAINTENANCE AND SECURITY AUTOMATION Figure 5.2 – Cargo Handling Robot I 5.2.1 CENTRAL COMPUTING UNIT (CCU): The Central Computing Unit (CCU) of Aresam will be located in the Core (i.e., the Central Cylinder). It will supervise the Sub-Computing Units (SCU), present in all six modules. The station’s central computer, (nicknamed “Evermind”) will control the Dynamic Positioning Systems as well. The Evermind will control the Climate Systems (Blizzard), Agriculture System (Incubus), Communications System (Twilight), Transport System (Mercury), Cargo-Handling and Automation Operation System (CHAOS), Power Generation System (Helios) etc. All the CCU computers and the SCUs will be installed with VxWorks Operating Systems, which is the preeminent real-time operating system available. It provides the ability to update the entire computing system in real-time with the information from the various subsystems. For data storage, conventional magnetic and optical storage devices such as hard drives will be used. The core computing systems will use RAID 7 (Redundant Array of Independent Disks Level 7) hard drives for data storage. RAID 7 is the most stable storage system, which allows for enhanced backup functionality. The details of the RAIDs are as follows: Data Storage Specification: Number of Disks - 2200 (including 200 spares) Capacity (Per Disk) - 400 TB @ 50,000 rpm Total Raw Capacity - 800 PetaBytes Bandwidth - 10 THz. The CCU will be installed with off-the-shelf equipment, and it will communicate with all the SubComputers via the Fiber-Optic Backbone (FOB). The Sub-System Units will only be accessible by the maintenance crew (or anyone else with authorization), and will be guarded by high level security consisting of the Iris scan. The SCUs will allow the maintenance crew to keep an eye on all the Life Support Systems and ease out any errors immediately. The processing Power required for each system on the settlement will be as follows: Climate Control (Blizzard) - 10 THz Power Generation (Helios)– 7 THz Communications (Twilight) – 7 THz Transportation (External and Internal) (Mercury) – 10 THz -Page 30- Northdonning Heedwell Aresam .::. Mars Space Settlement Cargo Handling and Automation Operating System (CHAOS) – 10 THz Agriculture (Incubus) – 6 THz. 5.2.2 SECURITY AUTOMATION The entire station will be surveyed continuously via Wi-MAX outfitted Wireless Closed Circuit Cameras (WCCC). The cameras will be portable, and will be attached to the street and traffic lights, corridors etc. at regular intervals. They will be completely mobile as their attaching mechanism will be magnetic. The cameras will have High-Resolution Pixel Recognition Technology, which can identify the face of each and every resident of Aresam. All residents of Aresam will be implanted with a subcutaneous chip will include the following details: Personal Details Bank Account Details (Credit/Debit) Tracking Device. The Subcutaneous chips will act as ID tags for the residents on Aresam. These will also act as what we call “Credit/Debit Cards” today. They will also act as access IDs to a limited no. of services and places like homes, schools, offices, ticketing for the Monorail Mass Transit System (MMTS), any commercial areas, recreational areas, personal vehicle activation, etc. For high security areas like the Communication Sphere, the Control Room, the maintenance nodes, the Docking Area, the Manufacturing unit, etc. the Iris Scan System (ISS) will be used along with subcutaneous chips as an extra precaution. The dual security provides more protection at the High Risk Areas and protection of privacy and personal data. Car securities include the subcutaneous identification and thumb gel imprinting for initiating ignition. Figure 5.3 – A Surveillance Robot Incase of a crime, the suspect will be tracked down by the Department of Justice on Aresam with the help of the implanted sub-cutaneous chip. If the suspect is to be pursued in a car, the WiMAX network will be put to use to stop the car wirelessly. Aresam will have a small team of security personnel and police officers. They will be assisted by the latest available technologies and robots. All security personnel will be armed with Taser Stun guns and sticks which will be used in the most extreme cases and at the discretion of the personnel. They will have surveillance and bomb disposal robots at their disposal in their operations. 5.2.3 MAINTENANCE AND REPAIR For a structure so large it is bound to get damaged every now and then. To prevent or repair this damage Aresam has an array of robots built to pin point precision, for their various functions. The modules of the torii are littered with maintenance nodes situated at regular intervals of 100 meters. These Nodes control all maintenance activities from Hull repair to sealing up pipeline leaks. These nodes have direct access to the outside of the settlement to facilitate Hull repair The nodes are in turn controlled by the CHAOS’s Central Computing Unit (CCU).The nodes initiate regular maintenance checks just as a safety precaution and makes sure all systems are in order. Internal repair has been assigned to three different robots: SnakeBots and Spider drones Modified Kronos (See Section 5.1.1) and Entomopters. -Page 31- Northdonning Heedwell Aresam .::. Mars Space Settlement The Kronos will be modified and used for internal maintenance. The Kronos will constitute of two prehensile, yet powerful limbs to facilitate repair of any kind. For special situations such as fires or an explosion or a structural collapse, the Kronos can be further modified. The Kronos will be assisted by its own wing of highly mobile flying insects call the Entomopters with inbuilt WiMAX to send the data its extremely sensitive environmental sensors acquire, to the Maintenance node and simultaneously to its parent Kronos. Pipeline maintenance has been assigned to the SnakeBots and Spider drones. Both will be deployed underground, from beneath the maintenance node and will detect leaks and other minor internal structural defects. The SnakeBot and Drones are composed of Electro active polymers, chips, a small power source and the required equipment, specific to the situation. Hull repair will consist of teams of 2 types of robots: The PSA ll Modified Robonaut (See Section 5.1.1). The PSA ll will be used mainly for reconnaissance and damage evaluation (if any).It will work in free space in a zeroG environment so for mobility it will use micro-propulsion devices. For reconnaissance purposes it will use a camera, Range finder wireless connection to its maintenance node Figure 5.4 – The Roomba and few Modified Robonauts, a solar cell as a power source and additional lithium ion batteries for prolonged usage. It will be coated with polyethylene. So it may be capable of working during solar flares and in presence of other solar radiation. Name Use Roomba Specification Voice activated cleaning robot, mainly Roomba can clean carpets, linoleum, utilized for household purposes. and tiled and Hardwood floors.

RCM converts chemical energy into kinetic energy through direct non-combustive chemical reactions. Particular benefits of the RCM are that it requires no ignition source, is anaerobic, and generates electrical energy thermoelectrically. -Page 32- Northdonning Heedwell Aresam .::. Mars Space Settlement The Robonaut which too like the Kronos was a construction robot will be modified to take up a job as maintenance robot. It will be specifically outfitted for repairing the damage if any. Since it is already outfitted with Zero-G propulsion systems it will not require any modification in that sector but instead will be outfitted with a camera and its clamps will be replaced with the required equipment. The vehicles entering the settlement will be cleaned in the docking system through electrostatic cleaners. These vehicles include those coming from Mars and those coming from long space travels for use on the settlement. There will also be decontamination chambers for further removing alien matter. 5.3 DOMESTIC AUTOMATION On Aresam, the typical house will also be automated like the rest of the settlement. A smart home controlled by a residential computer subsystem will monitor all the household tasks thereby reducing human intervention. Small wireless sensors imbedded in the wall will record the Occupants’ movement inside the residence and hence tailor to their environment. Speech recognition and synthesis system will allow the users to interact easily with the house by simply talking naturally. A software package and central computer (The Virtual Butler) will use information from speech, feedback from the appliances and the user location information to make intelligent decisions. In this house everyday appliances will be fully integrated to work in unison to respond to the (preprogrammed) tastes of anyone. Equipped with such innovations such as a toilet that monitors weight, sugar levels and emails its results to the user’s doctor, the smart home is one tailored especially for Aresam. 5.3.1 NETWORK PLAN All six SCUs will have a little less processing power than the Evermind, but will have the capacity to work individually without the supervision of the CCU. In case of failure of one or more Sub-Computers or the CCU computers, the other Sub-Computers will continue to function as normal. Cyber Kiosks will be provided at every Module to allow the residents to access the internet and use the Aresam Intranet. Commercial computers will obtain access to the internet through the Sub-Computers. All the Sub-Computers will be directly connected to the Evermind through the FOB. The Cyber Kiosks and commercial computers will use the Sub-Computers as Hubs to connect to the network. Such an indirect connection will prevent unnecessary data traffic congestion, thereby speeding up the network on the whole. In addition to their basic tasks, each SCU will be assigned the task of controlling a Life Support System. The Transport System, Communication System, Agriculture System, Climate Control System, Cargo Handling and Automated System and Power Generation System each will be controlled by one of the six SCUs. The Transport SCU will control external and internal traffic, the Monorail and the general traffic signals, etc. The Climate Control SCU will regulate temperature and all the associated mechanisms. Similarly, all the other Life Support Systems will be operated by an SCU. Like the CCU computers, the SCUs will also be equipped with VxWorks Operating Systems to allow more efficient control over their tasks. 5.4 INTERNET THROUGH “PERIODIC UPDATES” Imagine having to wait 8 minutes for Google to open on your browser. To solve this problem, we will be using “Periodic Updates” for using Internet2. It is not possible to use the internet in real-time when distances are so large. Therefore, Internet on Aresam will be saved on the computers of the Station itself. The copy at the Station will only be a partial version; only those parts deemed necessary will be saved. A copy of Internet2 will be taken along when setting up the station, and afterwards, it will be updated periodically (about once a week during low-usage hours) using the communication systems. This is done so that no bandwidth is wasted during Earth-Mars transmissions. This process will also eliminate the delays that would otherwise be inevitable in real-time Internet-access. For access to information that is unavailable at the Station’s Internet database, requests can be made to the Central Computing Unit so that the required data can be downloaded from Earth. -Page 33- Northdonning Heedwell Schedule and Cost Aresam .::.

Mars Space Settlement 7.0 BUSINESS REQUIREMENTS Aresam would have 15000m2 reserved for commercial offices this area will be provided to companies to establish their branches on the settlement. The concerned companies may design and build their own offices within the norms of Aresam using NH’s construction robots or may ask us to design a office for them. The companies will receive high speed internet and communication options. The offices will be spread out across the residential cum commercial torus so as to not overload a single SCU. The cost of building the settlement will be enormous and therefore our sources of finance will include loans from various countries and international banks, the sale of bonds to the residents of Aresam and also to residents of Earth. Once the settlement is established and functioning it‘ll be able to levy taxes and raise finance from the sale or lease of land to the private industry. Real estate will also be auctioned. The various industries on Aresam will be: Semiconductors manufactured in the Central Sphere of Aresam will be 1000 times faster than the conventional ones generating estimated revenue of about $35 to $40 Billion Dollars The Micro Electro Mechanical Systems (MEMS), which can only be manufactured in Low/zero-G condition, will also fetch around $10 to $20 Billion The use of Low-G on manufacturing of Pharmaceuticals has been considered an asset for humanity for a long time. The variable-G environment in the Mobile Sphere on the Spokes will facilitate the process, generating around $10 to $12 Billion There will be a separate industry for heavy manufacturing of Reusable Launch Vehicles and MARSUVs which will serve as a gateway to Mars. The various industries (excluding the Pharmaceutical one) will be setup inside the central capsule. Other business opportunities include exporting material mined on Mars and its moons, Phobos and Diemos. Most of the mined material will be used in construction of the structure but the surplus will be sent to Earth using the tether system right from the time mining begins. Tourism is another asset which will be exploited to earn profits on Aresam. A space tourist has to pay at least $10 Million as per today. Aresam will host at least a 1000 tourist annually and by reducing the cost to just $1 Million for a trip to mars, we get the figure of $1 Billion. Since Aresam is to be a portal for the rest of the solar system, the ships docked in its docking bay will rent their space here paying some amount for it. The cargo ships will also pay some excise duty. All commercial activities on Aresam will be taxed with Value Added Tax (VAT). The amount will be 20% since we are not taxing the residents on their other possessions and income. As Aresam will serve as gateway to Mars, we have the advantage of levying taxes such as Octroi etc., on the mined materials which would be exported through Aresam. Thus we can see that, in the long run, Aresam is an extremely profitable venture. -Page 38- Northdonning Heedwell Compliance Matrix Description Page No. EXECUTIVE SUMMARY 1 STRUCTURAL DESIGN 2 External Configuration Shape and Design -
