The primary application for the compressor proposed is to compress Martian atmospheric carbon dioxide to feed a solid oxide electrolysis system for oxygen production as part of an ISRU plant for the Mars 2020 mission. Furthermore, the same technology will be applicable for larger production plants for a Mars sample return and an eventual Mars human mission. This space qualified compressor may also have applications for other planetary missions to Venus, Enceladus, and Titan, as well as for NASA efforts in the area of atmospheric sampling and climate research. The commercial potential for a small, high efficiency compressor are numerous. We foresee that this unit will mainly be incorporated in high value analytical instruments for atmospheric sampling and for systems to detect airborne chemical, biological, and nuclear warfare agents.
