During the continuing effort to design the Space Station Freedom extravehicular activity (EVA) life support system, NASA has extensively researched and evaluated venting and non-venting technologies. In conducting this study, NASA has concentrated on a system-level approach that emphasizes on-orbit regeneration capabilities, minimization of expendables, minimal on-orbit maintenance requirements, a four to eight hour EVA capacity, and a system weight and volume close to the Space Shuttle unit. This paper will describe various venting and non-venting technologies and review the estimated weights and volumes for the options on a component and system level. At this time, a final design concept for the Space Station extravehicular mobility unit has not been chosen.
