Medium-sized view of MGS MOC Picture of the Day, updated daily

NASA/JPL/Malin Space Science Systems

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a frost-covered surface in the martian south polar region. As the seasonal frost begins to sublime away, local variations in surface texture—mostly dendritic cracks, in this case—lead to early defrosting in some areas. Those areas already defrosted appear dark in the image.
