On December 30, 1999, the Mars Society selected Infrastructure Composites International (Infracomp) to build the primary structure of the Mars Arctic Research Station (MARS). The structure, which will be a two-deck Mars habitat and laboratory prototype 27 feet in diameter, will be built by Infracomp at the Mesa Fiberglass facility in Commerce City, Colorado, using an advanced fiberglass honeycomb technology pioneered by the two companies.
