Gas Abundances and Isotope Ratios in the Martian Atmosphere and Evolved from Rock Pyrolysis- Benchmarks to Understanding the Planet's Evolution

Science results from the Sample Analysis at Mars (SAM) suite on Curiosity will be summarized, from both evolved gas analysis from rock pyrolysis and atmospheric analysis. This will include organics, oxychlorine/ perchlorates, nitrates, and isotope ratios in C, N, O, and S with a focus on D/H, 13C/12C, 18O/16O measurements made by both the tunable laser spectrometer (TLS) and quadrupole mass spectrometer (QMS), and the TLS detection of atmospheric methane.
