Called “Space Nomad” the concept, conceived by Gábor Bihari at the University of Debrecen, Hungary and Thomas Herzig, CEO of Pneumocell Co., Vienna, Austria is described in paper available on Academia.edu. The elegant design takes into account the payload capacity of spacecraft of the near future and in situ resources available on Mars to arrive at a safe and feasible solution.
The main side wall is a tri-layer membrane with two gaps to provide insulation. The outer wall gap contains a vacuum and the inner one is gas-filled. The protruding ceiling provides shielding from radiation and protection from micrometeorites that impinge at high angles to the structure. The habitat is not completely closed as the design has a system for processing the Martian CO2 atmosphere, conditioning it for use by the greenhouses while producing breathable air and replenishing losses.
A modified version of the habitat could be deployed at the Moon’s polar region as a preliminary step toward validation of the design before a Mars mission. Unlike the Mars settlement, this structure would have to be airtight and changes would be required to the mirror system.
