The world is not enough for Foster + Partners, whose designs for a speculative lunar habitation were unveiled as part of the special EARTH to SPACE Festival taking place at the Kennedy Center in Washington, D.C.from March 30th through April 13th, 2025.The British firm's contribution, titled From Earth to Space and Back, speculates a four-person habitation built using lunar regolith soiland erected underneath the surface of the moon to protect against gamma radiation and meteorites. The base will comprise an inflatable dome structure that is then covered in layers of the dense (1.5 g/cm3) material in situ.This is being presented also to posit a similar Mars human habitat and is part of the firm's involvement with both NASA and theEuropean Space Agency that extends to 2012.
