Caption:
26 January 2004
This January 2004 Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows what the martian south polar residual cap looks like in the middle of summer. Sunlight illuminates the scene from the top/upper left. The picture shows mesas composed of frozen carbon dioxide, each about 2-5 meters (6-16 ft.) high. Sunlight has darkened the slopes around the mesas as carbon dioxide sublimes away throughout the summer. The image is located near 86.2°S, 351.4°W, and covers an area 3 km (1.9 mi.) wide.
