ISS Image: Sand dunes in the Marzuq Sand Sea

Sand dunes in the Marzuq Sand Sea, southwest Libya are featured in this image photographed by an Expedition 18 crewmember on the International Space Station. This detailed view, taken from low Earth orbit, shows classic large and small sand masses of the Central Sahara where wind is a more powerful land-forming agent than water. “Draa” dunes (from the Arabic for “arm”) are very large masses of sand and appear here as the broad network of yellow-orange sand masses (the image covers a region approximately 9.4 kilometers wide), with smooth-floored, almost sand-free basins between them.
