ABSTRACT:
A self-supporting pressurized or unpressurized membrane structure for lunar habitation and operation. The pressurized membrane is made up of continuous and leak-proof fabric membrane that encapsulates the entire structure and is capable of withstanding temperatures of about -190.degree. C. to about +140.degree. C. this structure has a skin preferably made up of two-spaced apart fibrous skins with a latticed web between them and foam material filling the space between the skins. Lunar soil supports the lower portions of the spherical, spheroidal, by means of a compression ring beam, or arched structure, and a lunar soil cover of up to ten feet covers the structure. The unpressurized membrane structure has a double-skin membrane arch or dome that derives its structural strength from structural foam injected into the double-skin wall of the roof.
