The development of economically and operationally sustainable constructionConstruction technologies is critical to establishing a permanent human presence on the MoonMoon and, eventually, MarsMars. Future exploration-class missions to deep space will depend on safe, durable, and protective housing and infrastructure for mission success. Without resilient, durable, and protective shelters, as well as foolproof constructionConstruction technologies to build them, protecting future crewmembers from the extreme hazards of deep space will be nearly impossible. These hazards include, but are not limited to: radiationRadiation from galactic cosmic rays and solar particle events, micrometeorite impacts, protection from extreme temperature swings, the lack of a breathable atmosphere, the risk of toxic perchlorates from Martian regolithRegolith and dust plumes, and more. In fact, the constructionConstruction of habitats for future crewmembers, as well as civic infrastructure to support small planetary base camps, may be two of the most critical milestones for realizing future planetary settlements.
