2.1 – Where do you want to build your Moon Camp? Explain your choice.
Our base will be built in the De Gerlache crater located 30 km from the South pole of the Moon. We chose this site because of its relative flat surface and its abundance in resources. The crater contains an extensive Permanently shadowed regions in the centre and multiple smaller PSRs around the crater rim that may harbour icy regolith deposits, another resource, for crew consumables, radiation shielding, and propellant.
Thus, our base is surrounded by vital terrestrial resources that we can exploit to sustain human life on the Moon Camp. The de Gerlache crater is not naturally abundant in helium-3; the extraction of the materials will be performed by way of robots that will travel and extract the radioisotope from Copernican regions of the Moon.
2.2 – How do you plan to build your Moon Camp? Consider how you can utilise the Moon’s natural resources, and which materials you would need to bring from Earth. Describe the techniques, materials and your design choices.
Given the fact that the building surface is covered by a layer of moon dust, the first step in building our camp is sending robots to clean until they reach the first geologically stable sediment. They will also remove any jagged terrain that might interfere with the base’s stability and take additional precautions to ensure its structural integrity. The second step in the construction is bringing the space modules with the help of 15 Orion spaceships. The rooms will be connected by 3D printed tunnels made from regolith and the 8 bigger modules will be assembled with the help of robots and the rooms will be furnished accordingly. All the units come equipped with windows made from barium silicate glass to allow the natural light flow. The oxygen, carbon dioxide and water pipes made from copper are also installed by robots. Finally, after the base is installed, the crew will land with the remaining supplies such as water and food and they will start the production of oxygen trough the three chlorella farms each with two 3,85 m2 tanks with the capacity of 5 m3. The members will plant crops and install the laboratory and the communication centre. The main mining robot will be transported and readied for use by the robot specialists. At this point our space mission begins.
2.3 – How does your Moon Camp protect and provide shelter to your astronauts against the Moon’s harsh environment?
Another challenge is the harsh lunar environment, which exposes the Moon base to micrometeoroids, solar radiation, and dust storms. These hazards can damage equipment, threaten the health of astronauts, and disrupt mission operations. First, outer space radiation is a concern on the Moon due to the satellite’s almost inexistent atmosphere.
In this regard, our moon base is equipped with a set of 60 cm thick walls that have a sandwich-like structure. From the outside in, the wall contains a layer of aluminium, then Reinforced Carbon Carbon, air, Reinforced Carbon Carbon, a space from installations such as pipes, aerogel and finally, another layer of isolating aluminium | inside space, that protect the crew from beta radiations and temperature fluctuations. This also helps mitigate damage in the event of a meteorite impact. As mentioned earlier, the glass is also an effective radiation blocker.
Secondly, we must consider the extreme temperatures present at the southern lunar hemisphere. Our base comes equipped with a central heating system that comes into play both in cooling the base down during periods of high temperatures and provide heat when the region is cold. Thirdly, for protection against moon dust, which can prove lethal, we will make use of high-quality space suits and an airlock to prevent contamination. In the event of an internal accident, the airtight doors will stop the fire or explosion, protecting the crew bedrooms.
Lastly, contact with Earth is essential in case of an accident therefore the communication center will be immediately closed off from the rest of the base protecting the room as much as possible. Two big modules are separated from the main camp, namely the robot garage and the storage room. They are not connected to oxygen pipes to prevent any possible leaks. In this regard, the base also offers two exits making evacuation safe and efficient for the crew.
