The 621 mile-by-1,240 mile (1,000 by 2,000-kilometer) region of Tyrrhena Terra (outlined by the white box in the inset) sits between two regions of low altitude in Mars ' southern hemisphere, as shown in this global topography map. Hydrated minerals were found in 175 locations associated with impact craters in Tyrrhena Terra. In a new study, ESA’s Mars Express and NASA’s Mars Reconnaissance Orbiter zoomed in on craters in on these ancient southern highlands to learn more about the history of water in this region.
