The initial moonbase would need to be self-sufficient. It would need to be designed for protection against extreme temperatures and high radiation levels on the Moon. The base life support system would be entirely closed. All waste gases, liquids, and solids are recycled, and there is a food production facility including a greenhouse.
With certain sites near polar heights receiving sunlight more than 80% of the time, general power requirements could be satisfied by solar energy. At a more equatorial location, for the night period of 14.75 days, when the solar power would not function and for lunar manufacturing, fuel cells or the installation of a nuclear power generating station would probably be required.
First Moon Habitation
The initial moonbase habitation could be constructed by linking together metal habitat canisters and inflatable structures. For radiation protection, these units would need to be buried under a layer of lunar regolith (soil) using excavation equipment. This video shows a lunar bulldozer under development in early 2008. The basic infrastructure will include life-support structures and climate control system, a solar power plant, an oxygen generator plant, a lunar ice processing plant, a greenhouse to produce food, plus the excavation of a Lunar spaceport, and the preparation of a supply processing and storage area.
A major problem with inflatable structures is that in the moon's vacuum, there is little protection from micrometeorites. Catastrophic depressurization could occur if a high velocity projectile penetrates the membrane. A solution, as with radiation, would require covering the inflatable habitats with a layer of protective regolith dug out of the moon's surface.
