Defrosting Terrain

June 29, 2012
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows dark spots and streaks formed in seasonal frost covering terrain in the martian south polar region. This springtime image shows the frost, which formed in the previous autumn and winter, as it is starting to change and sublime away. Dark streaks indicate the direction of winds that have moved some of the defrosting material. MGS MOC Release No. MOC2-1137, 29 June 2005
