The technical papers were not presented in person due to the inability to hold the event as scheduled in Lisbon, Portugal because of the COVID-19 global pandemic.We report on the scientific and engineering progress for the second technology demonstration unit (TDU2) of the Spacecraft Atmosphere Monitor (S.A.M.). The S.A.M. TDU2 is a compact gas chromatograph mass spectrometer (GCMS) for monitoring both the trace volatile organics and the major constituents in the astronaut cabin atmosphere. Progress on the micro electro-mechanical systems (MEMS) gas chromatograph is detailed, showing sensitivity and selectivity of the TDU2 analytical measurements. The TDU2 capabilities for monitoring the cabin air major constituents is also detailed, highlighting improvements from the first S.A.M.
