An important focus of the decade-long Mars Surveyor Program is the search for evidence of past or present life and or prebiotic chemistry. Based on studies of terrestrial analogs, the highest-priority sites for a martian fossil record include such lithologies as fine-grained, clay-rich detrital sediments, water-lain pyroclastics and evaporite deposits of terminal paleolake basins, the deposits of mineralizing springs (including hydrothermal), and mineralized zones (hard-pans) within ancient soils. The systematic exploration for a martian fossil record critically depends on locating accessible surface outcrops of these and other aqueously deposited sediments. The following discussion identifies the steps needed to optimize a plan for implementing the present strategy for Mars exopaleontology.
