6 January 2004
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows sand dunes in southern Galle Crater, east of Argyre Planitia. The sand that comprises these dunes, like other dunes on Mars, is dark, but at the time this picture was acquired during early southern summer, the dunes were covered with a coating of bright dust. Occasional, passing dust devils or wind gusts created the dark streaks seen on a few of the dunes. The dunes are located near 51.9°S, 31.2°W. The image covers an area 3 km (1.9 mi) wide; sunlight illuminates the scene from the upper left.
