Sand Dunes in Proctor Crater
Sometimes, pictures received from Mars Global Surveyor's Mars Orbiter
Camera (MOC) are 'just plain pretty.' This image, taken in early
September 2000, shows a group of sand dunes at the edge of a much
larger field of dark-toned dunes in Proctor Crater. Located at 47.9°S, 330.4°W,
in the 170 km- (106 mi-) diameter crater named for 19th Century British
astronomer Richard A. Proctor (1837-1888), the dunes shown here
are created by winds blowing largely from the east/northeast. A plethora
of smaller, brighter ripples covers the substrate between the dunes.
Sunlight illuminates them from the upper left.
