Students, engineers and other space enthusiasts will soon begin taking turns performing experiments in a Colorado-built research station that simulates conditions on Mars. The two-story, 27-foot-diameter building, built in an Aurora warehouse, has been shipped and reassembled in southern Utah. Six people at a time will live and do research in an area between Capitol Reef and Canyonlands national park. It is the second habitat built by the Colorado-based Mars Society to simulate the harsh conditions humans would encounter on Mars. The society’s first, the Flashline Arctic Research Station, was field-tested last summer on Devon Island in the Canadian high Arctic. The Mars Society has an international membership of engineers, enthusiasts and many NASA employees dedicated to exploration and settlement of Mars. More than 400 people volunteered to work in the new station.
