Abstract
The Spacecraft Atmosphere Monitor (S.A.M.) is a miniaturized gas chromatograph mass spectrometer (GC/MS) instrument that is being developed for monitoring the cabin atmosphere for human spaceflight missions. The first Technology Demonstration Unit (TDU1) operated successfully aboard the International Space Station (ISS) from August 2019 to July 2021, exceeding its 1 year planned operational lifetime. The TDU1 continuously monitored the ISS cabin atmosphere for the major constituents. In June 2020 the TDU1 was also reconfigured at the request of the ISS vehicle office and successfully determined that there was no benzene leaking into the ISS atmosphere. The technology demonstration unit #2 (TDU2) is scheduled to be deployed on the ISS in 2022. While on-station, TDU2 will continuously monitor the major atmospheric constituents as well as trace organic volatiles. The S.A.M. TDU2 uses the same quadrupole ion trap mass spectrometer (QITMS) sensor as in TDU1, but includes a MEMS preconcentrator, gas chromatograph, and microvalve system. Its miniature, ruggedized form factor allows the S.A.M. to be aisle-deployed to monitor the cabin in different locations and during activities such as exercise and sleep. The operational performance of TDU1 and the current status of TDU2 will be discussed.
