In support of NASA's Exploration Mission low-temperature scientists and engineers have investigated the process of extracting volatile materials from the lunar regolith, their purification/liquefaction, and storage. Volatiles such as O2, N2, He and water can be used to support human habitation, while H2 and O2 can be used as rocket fuel. Using a sorption pump, passive thermal radiators, temperature control, and a small number of storage vessels and valves, a purification and storage system can be designed to operate inside a permanently shadowed polar crater where volatiles are expected to be most abundant. The basic approach can be used as the basis for a small experiment on a prospecting mission, which will serve as a proof of concept for a much bigger cryogenic fluids facility to support NASA's human exploration effort. A similar design with sufficient radiation shielding can be operated on the Moon's surface.
