Mars Global Surveyor Mars Orbiter Camera

MGS MOC Release No. MOC2-1177, 8 August 2005

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows bright (and a few dark) wind streaks formed in the defrosting carbon dioxide of the south polar seasonal frost cap. Unknown is whether the streaks form when wind picks up, moves, and deposits ice particles, or whether wind erodes down into the ice to form the streak pattern.
