Flight Integration and Test of the Mars Organic Molecule Analyzer (MOMA)

Abstract : The Mars Organic Molecule Ana-lyzer (MOMA) investigation [1] on the 2020 ExoMars rover [2] will examine the molecular composition of crushed samples acquired from depths of up to two meters below the martian surface, where organics may have been protected from radiative and oxidative degradation [3,4]. MOMA combines pyrolysis-gas chro-matography/mass spectrometry (pyr-GCMS), both with and without chemical derivatization, and laser desorption mass spectrometry (LDMS), in coordination with the other investigations in the rover's Pasteur Payload, particularly the Raman [5] and MicrOmega [6] instruments. With its two modes, MOMA detects compounds over a wide range of molecular weight, volatility, and mineralological association.
