The Mars Desert Research Station is being fabricated for the Mars Society by Built on Integrity (BOI), of Boulder City Nevada. Founded by Scott Fisher, of the Fisher Space Pen company, a longtime supporter of space exploration in general and the Mars society in particular, BOI has developed a proprietary construction technology combining a steel frame, foam core, and elastomeric skin to produce an ultra lightweight structure with extremely effective insulation properties. The MDRS will use this technology to produce a station that is the same size as the fiberglass honeycomb Flashline Station, but which weighs less than half as much. The Mars society intends to take advantage of the lightweight nature of the MDRS to make it mobile, moving it to support exploration at several different desert locations in the course of its operating lifetime.
