2.1 – Where do you want to build your Moon Camp? Explain your choice.
When constructing a lunar base one must account for many life-threatening circumstances on the moon which include the following:
- “No” Atmosphere
- Strong cosmic radiation
- Extreme varying temperatures
- Meteorites
- Supply problems (Section 3)
Considering these factors, the optimal location is underground in one of the moon’s lava tubes. Lava tubes are natural underground tunnels formed by ancient lava flows that solidify on the surface but continue to flow underneath, leaving behind a network of empty tunnels. These tunnels provide a stable and protected environment from the harsh lunar conditions while optimally providing a compromise between average temperature, water resources, and the concentration of helium-3 in the surrounding regolith. In order to secure communication with Earth, only a lava tube located on the daylight side of the moon is suitable.
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.
In order to save energy, an artificial atmosphere inside the lava tube will be established. By doing this, it is possible to live within the atmosphere without suits. Inside the artificial atmosphere our base is made up of walls inflated with oxygen, making them thermally insulating.
Since the lava tube floor is uneven and angled, a base floor, which forms a level area for the facilities, should be built. Supports anchored in the ground with steel grids would be suitable, as they are easy to transport and practical. This could be achieved by using chemical dowels.
During the construction phase, a team will be stationed on the moon, requiring a temporary base to be built. This base should be simple and quick to set up. Carbon fiber reinforced structures would be optimal, since transport weight limits should be considered. The temporary base needs enough space to accommodate the team, vital resources, materials and tools for building the actual base. In addition, we need a flat surface where all probes and capsules with resources from the Earth can land. This area must provide enough space for landing and for rovers or other means of transportation that will bring the materials and people to the base or directly to the construction site.
2.3 – How does your Moon Camp protect and provide shelter to your astronauts against the Moon’s harsh environment?
Building a lunar base in one of the Moon’s lava tubes provides several advantages for protection and providing shelter to our crew.
Firstly, it would protect our crew from the dangers of radiation exposure. The Moon has no protective magnetic field to shield from harmful solar and cosmic radiation, which can be a significant health risk for astronauts. The thick layer of rock above the lava tube would act as a natural radiation shield, reducing the exposure to harmful radiation.
Secondly, the stable temperature inside the lava tube provides a more comfortable living environment for our crew. The Moon’s surface experiences extreme temperature fluctuations, with daytime temperatures reaching up to 120°C and dropping to -170°C at night. The stable temperature inside the lava tube would provide a more habitable environment for our crew, eliminating the need for complex heating and cooling systems.
The lava tube also provides natural protection from micrometeoroid impacts, which can pose a significant risk to equipment and personnel on the lunar surface. The thick layer of rock above the lava tube would absorb any impacts, reducing the risk of damage or injury.
In addition, the lava tube provides a ready-made structure for our base, reducing the construction time and cost. The tunnels can be modified and outfitted to suit our needs, with minimal excavation required.
Building our lunar base in a lava tube provides a natural shield against radiation, stable temperatures, protection from micrometeoroid impacts, and a pre-existing structure, making it an ideal location for our crew’s shelter and protection on the Moon. Since temperature fluctuations are only a minor issue due to the lava tube and maintaining a stable communication with Earth is important, the base is in a central location on the daylight side of the moon.
