    Launched June 10, 2003, Spirit landed January 4, 2004 in Gusev Crater. In May 2009, after traveling 7,730 meters, with only five working wheels remaining. the rover became imbedded in soft soil at a site named Troy by the team. Later Spirit became silent and, after rescue efforts failed, NASA ended the recovery attempt on May 25, 2011

    Spirit's contributions to better understanding martian atmospheres were derived from the pan-chromatic camera (including atmospheric opacity measurements and dust devil mapping to further constrain atmosphere-surface interactions ) and observations of near surface temperatures with the Mini-TES instrument.

    The atmospheric data complement was

    Rover Atmospheric Entry Profile (Density, pressure, temperature versus altitude)

    Pancam-derived 440 nm and 880 nm Atmospheric opacity

    Mini-TES near-surface atmosphere temperature profiles ( note; No derived product is available. The reduced data are available in the PDS Geosciences node)
