Abstract

Three prime candidate sites for the astrobiological exploration of Mars have been identified on the basis of its hydrogeological history. Each of the sites corresponds to a major inundation phase of the global hydrological model. The Terra Meridiani site is related to the Noachian to Hesperian time, which suggest an aqueous-hydrothermal origin. The Mangala Valles relates to Late Hesperian to Early Amazonian time, where diminishing martian episodic hydrologic events over geologic time are recorded representing a later pulse of tharsis-driven hydrologic activity. The Orcus Patera site relates to Amazonian time, which is a volcanic caldera or impact crater where reduced ponded bodied of water may had existed during almost contemporary times.
