The 2009 Mars Science Laboratory (MSL) is being designed to quantitatively asses the region near its landing site on Mars as a potential habitat for present or past life ( http://mars.jpl.nasa.gov/msl). The goals of MSL are to (1) assess the past or present biological potential of the target environment, (2) to characterize the geology and geochemistry at the MSL landing site, (3) to investigate planetary processes that influence habitability, and (4) to characterize the surface radiation. The Sample Analysis at Mars (SAM) suite of MSL addresses several of the mission's core goals with a gas chromatograph, a mass spectrometer, and a tunable laser spectrometer. These instruments will be designed to measure either atmospheric samples or gases extracted from solid phase samples such powdered rock cores. The SAM capability to measure a broad range of organic compounds is designed to help unravel the source of organic compounds that might be present in near surface samples and their potential chemical transformation paths. The SAM ability to measure isotopes of carbon, oxygen, hydrogen and other light elements in sampled organic and inorganic species provides complementary information.
