An Integrated Regenerative Air Revitalization System for Spacecraft

Future long-duration manned space missions will require efficient methods for maintenance of viable atmosphere in spacecraft crew cabins. Life Systems, working with NASA, has been developing an integrated regenerative Air Revitalization System (ARS) for removal of carbon dioxide and water vapor and replenishment of oxygen and nitrogen for spacecraft atmosphere. A one-person-capacity experimental ARS (ARX-1) has recently been developed and tested. This paper describes the ARS concept, prior development efforts, design and hardware features of the ARX-1, testing completed, the current test program, and a preliminary design for a one-person flight prototype ARS.
