Wearing an experimental spacesuit, the author walks past an adobe structure built using minimally processed soil employing In Situ Resource Utilization Technology. Using a minimum number of tools and equipment, this 36 cubic meter structure was erected by three people in five days. Such structures could provide ample radiation protection for the crew while an inflatable, inner membrane structure attached to an airlock would retain the earthlike atmosphere. By studying the merits and limitations of this technology in simulators like these, we are able to ferret out the problems and refine the deployment operation well in advance of the Mars 2030 mission.
