Our mission is to build a large self-sustaining facility that will house hundreds of people and to start construction by 2026. United Space Structures (USS) has developed a unique construction process for building very large permanent structures within lunar lava tubes. The advantage of building within lava tubes is that the lava tube provides protection from radiation and meteor strikes and so the habitat structure does not require to be hardened from these elements. The structures only need to create an atmospheric structurally stable enclosure that is thermally insulated.
