Orbiter Regenerable CO2 Sorbent Life Characterization 972264
The Regenerable Carbon Dioxide Removal System (RCRS) has been flying on Extended Duration Orbiter (EDO) versions of Shuttle since 1992. Life characteristics of an enhanced sorbent were evaluated after five years of service life on two Orbiter vehicles. Performance data is presented showing excellent carbon dioxide removal. Limited data forces a range of life predictions for the useful life of the sorbent.
