Cylindrical Habitats - Horizontal or Gary C. Fisher The Mars Foundation GFisher@MarsHome.org Rutgers University Symposium On Lunar Settlements Piscataway, NJ June 5, 2007 Background and parameters of this work The Mars Foundation’s Mars Homestead Project is an ongoing effort to define the first self-sufficient settlement for Mars. This effort produced an initial design, “The Hillside Base” using habitat structures, mostly cylinders, constructed on site from in situ materials over the course of 6 to 8 years by 12 people. The Hillside Base The Plains Base The Plains Base Three Generations of Habitats (Benaroya 2006) Prefabricated and preoutfitted hard shell modules. Assembly of components fabricated on Earth with some assembly required; and Large scale building structures comprised substantially of indigenous materials. The criteria of interest then are: Ease of assembly both from the standpoint of low labor input, but also requiring minimal tooling, especially imported tooling. Ease of transport of the finished structure. Ease of deployment – site preparation, positioning, attachment Thermal characteristics Radiation shielding – ease of applying a regolith cover Useful life Useable interior space Pressure retention Site independence – build and deploy these almost anywhere on the Moon. Why Cylindrical Habitat Structures ? For the purposes of creating in situ habitable spaces for a Lunar settlement, cylinder-shaped structures present the best near-term option over alternatives, such as: - spherical or dome structures - excavated structures - lined lava tubes - inflated structures (noncylindrical) - regolith covered masonry vaulted arches. Cylindrical Habitat Structure Options: - Length - Diameter - Hemispherical or flat end caps - Rigid or inflatable - True cylinder, ellipsoid or flattened - Single or multi-wall The primary consideration, however, is whether to stand the cylinder up vertically on an end, or lay it do
