The Isidis basin rim may be key to understanding Mars' past with future lander missions: this area enables the mission objective to explore Mars' climatic and geologic history, including the search for liquid water and evidence of prior or extant life in ancient terrains. While two safe candidate landIng sites for Mars Pathfinder were identified in Isidis Planitia, and one is being pursued for the Mars Surveyor 2001 Lander, the region around Isidis Planitia. in contrast to Tharsis for example, has only been lightly studied. The advent of new high resolution data sets provides an opportunity to re-assess the geologic context of this Impact basin and its rim within the Martian geologic sequence as a candidate site for studying Mars' ancient cratered terrain and ancient hydrosphere. This reexamination is warranted by the various hypotheses that Isidis was once filled with ice or water.
