Description: One of the major goals of the Mars science program is to identify exact locations of near-surface water or hydrated minerals on Mars. Evidence is mounting that Mars may have contemporary near-surface groundwater activity. Though very water-poor by terrestrial igneous standards, the SNC meteorivtes were found to contain evaporite minerals suggestive of groundwater activity within the past 1.3 Ga. More recently, the Mars Surveyor camera recorded images of geologically young seepage and outflow channels attributed to liquid water. The sources of these channels were suggested to be only a few hundred meters or less below the surface. If these channels are truly geologically young, thinly buried ice may still exist at the termination of these channels.
