Scientific paper

The Mars Atmosphere Resource Recovery System (MARRS) is a process that extracts oxygen and other minor components from the Martian surface atmosphere. The thin atmospheric gases are compressed, the carbon dioxide (CO2) is liquefied, and the lighter components are recovered and purified. Energy as heat re-expands the CO2 to produce the electrical and mechanical power need to compress and capture the atmosphere. MARRS takes unique advantage of the low ambient temperature on the Martian surface to separate oxygen and water from the bulk CO2 in an efficient, lightweight package. The availability of liquid CO2 in unlimited amounts enables efficient, open-cycle processes for reserve and emergency power, transportation and industrial uses. Together with a nuclear heat source, MARRS can satisfy many of the requirements for consumables and propellants for a human or large robotic presence on Mars. .
