The Hellas basin is a large impact crater in the southern hemisphere of Mars. It contains a vast plain known as the Hellas Planitia, and its western rim is enclosed by a string of rocky peaks named the Hellespontus Montes. This region was imaged by the High Resolution Stereo Camera on ESA’s Mars Express on 13 January 2014 during orbit 12 750.
