1. Moon Base Design Comparison By, Mudassir Ali Andrew Leonard

2. Lunar Base Competition 2010 • 102 Entries but only 15 that were realistic • Location: South Pole of Moon • Gravitational Difference: 1/6 of Earth • No Atmosphere • Getting things to Moon - $10,000/ lb • Primary Purpose: Provide a science, and technologydevelopment facility on the Moon • Most important scientific material so far is 300 kg of regolith brought back by ApolloAstronauts • Competition was to design a second generation base an international effort to build a permanent human community on the moon

3. Lunar Base Competition 2010 • Design Requirements: • Facilities located 3m (10 ft) below Lunar Surface for Protection from everyday radiation (not solar flares) • Minimal risk of solar Flares, vacuum of space, etc. • Human Comfort • All plans support a resident staff of 60 people • All entrants were to presume the infrastructure of a first generation base under construction by 2030, completed by 2040 • Two base designs that tied for 1st for Elegance and Feasibility Award in 2011: Craterville and Moon Capital

4. Craterville • Base acquires CHON: • Oxygen from Oxide Rocks. • Ex. Iron oxide, Titanium oxide • Hydrogen from water in Shackletoncrater • Nitrogen and Carbon are imported from Earth • A satellite will be skimming Nitrogen off Earth atmosphere while in orbit • Helium-3 exported to Earth and used for fusion reactors • Exporting from Moon to Earth done in aluminum containers • Carbon containers used from Earth -> Moon • Base Energy Source: • Helium-3 nuclear fusion reactor • Nearlycontinuous sunlight

5. Craterville

7. Craterville • Tower has reflective surface that takes in light and sends it down • Sunlight coming in laterally • Base has 3 layers 10 m apart and located underground • Protects against Radiation (including solar flares) • Top level- Agricultural level • In the case of a Solar Flare – go to 3rd level chamber • Exterior access • Water filled chamber (airlock) for people and supplies • Standard airlock for large/sensitive equipment • Water is acquired from dark areas in crater • A factory makes disks or cubes of ice and • Ice is then pulled up to lowest level of the base- materials processing area

8. Tom Schmit’sMoon Capital

9. Moon Capital • Base acquires CHON by importing everything • Base Energy source is through Solar Energy • Tower has reflective surface and is extremely large compared to Craterville • Base is placed on stilts • 3 meters (10ft) of regolith will block 90% of cosmic radiation • During Solar Flare- close garage type doors pile regolith on top and move people to bunker • Design is very inadequate for protection against radiation • Standard airlocks are used to get in and out of base • Water is acquired from a shallow crater • (no such crater is known to exist on the Moon) • => DESIGN FLAW

10. Extracting Minerals • Robots will be used to extract gasses, glass and metals from the lunar regolith • Japanese designing a robot base that doesn’t require human presence

11. Next Time… Botany!!! • Both of these bases featured greenhouses to grow food and raw materials. Next lesson we’ll focus on this. • In the food area, we will be talking about “staples”, protein sources in the absence of meat (other than fish and worms) and vitamins needed to stay healthy
