An image of the southern hemisphere of Mars acquired by the High Resolution Stereo Camera (HRSC) during Mars Express orbit 14150. In the lower part of the image, the southern polar cap of Mars is visible; it consists of both water ice and frozen carbon dioxide. The darkest areas are accumulations of volcanic sand.
