Abstract:

The first steps in the human expansion into space, which inevitably will occur during the next century, consist of the establishment of a human-tended base on the Moon followed by human missions and a human-tended base on Mars. Structures for both lunar and Martian bases face similar requirements and design criteria despite the differences in environmental conditions at these two sites. Consequently, the Moon is a natural testbed for both lunar and Martian structures. In both cases, the internal pressure is the major applied load, as the external pressure at both sites is structurally negligible. An inflatable structure made of a thin membrane is highly efficient in resisting the dominant internal pressure load. A generic modular inflatable structure that can be used on both the Moon and Mars is proposed and described.
