Hellas Planitia
instrument of Mars Global Surveyor. The crater depth is below the standard topographic datum of Mars. Hellas Planitia is a plain located within the huge, roughly circular impact basin Hellas located in the southern hemisphere of the planet Mars. Hellas is the fourth or fifth-largest known impact crater in the Solar System. The basin floor is around deep, deeper than the Moon's South Pole-Aitken basin, and extends about east to west. It is centered at It features the lowest point on Mars, serves as a known source of global dust storms, and may have contained lakes and glaciers. Hellas Planitia spans the boundary between the Hellas quadrangle and the Noachis quadrangle.
