Summary:

This preliminary review was prepared for the selection of a CO2 removal assembly for the Crew Exploration Vehicle (CEV). The CEV has a dual role in transporting crewmembers to ISS and as the Moon-bound spaceship. The LiOH-containing assembly is considered a reliable device for short missions, but unfavorable for longer missions due to weight and economic factors. Zoelite-based regenerative assemblies have been flight-ready and are good candidates when issues in valve and pump seal design are resolved. Solid-amine based CO2 removal assemblies have showed promises and redundancy. There are three integrated subsystems to be considered for oxygen recovery if needed. In addition, five emerging technologies have been rated at low-to-middle of TRLs, but they are only potential candidates for Advanced Life Support (ALS) applications and for the second-generation CEV. Major mission requirements have been identified for CEV design and operations
