Dark Martian Dunes

March 27, 2013
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows dark, windblown sand dunes in a crater in the Hesperia region of Mars. The steepest slopes on the dunes--their slipfaces--point toward the south-southwest, indicating that the winds responsible for the dunes blew from the north-northeast (top/upper right). MGS MOC Release No. MOC2-1138, 30 June 2005
