The south polar cap of Mars as it appeared to the Mars Global Surveyor on April 17, 2000. The polar cap from left to right is about 260 miles across. (NASA/JPL/MSSS)

The Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) acquired this image of the Martian north polar cap in early northern summer on March 13, 1999. The light-toned surfaces are residual water ice that remains through the summer season. The nearly circular band of dark material surrounding the cap consists mainly of sand dunes formed and shaped by wind. The north polar cap is roughly 680 miles across.
