A Space Analog for the Moon and Mars (SAM) is a complete Mars habitat analog located at the renowned University of Arizona Biosphere 2. SAM integrates a workshop, kitchen, common area and living quarters to support of up to four inhabitants from five days to a few months. A CO2 scrubber built by Paragon SD C provides mechanical life support. A pass-through airlock leads to an adjacent half acre Mars yard where pressure suits, rovers, and drones can be tested. The Mars yard will be modeled after a crater selected by NASA JPL as the first human landing site. In addition the SAM Mars yard will include varied terrain and select obstacles, a massive synthetic lava tube with skylight, and a gravity off-set rig to provide the experience of exploring on foot in lower gravitational fields.

In 1987 the 480 cubic meter Test Module was built as a prototype to the Biosphere 2. This hermetically sealed greenhouse and living space proved the functions of atmospheric recycling and potable water generation, food production and waste management, and mitigation of thermal expansion and contraction – total environmental control and life support for a single human sealed within. The longest closure lasted for three weeks. SAM integrates the fully refurbished Test Module as a research greenhouse and integral component of a bioregenerative life support system.
There is no single-run experiment that can result in an ideal solution for providing breathable air, potable water, food production and waste reprocessing for long-duration human space exploration. Rather, SAM will see unfolding experiments, findings, and prototypes for years in the making. Much as farming evolved from the art of crop rotation to the science of GPS driven cultivation and genetically modified organisms, living on the Moon, Mars, and in free space will demand constant improvements in our systems as humans move to new homes among the stars.
