Linear Dunes, Namibia
Linear dunes in the Namib Sand Sea, photographed by an astronaut aboard the International Space Station (ISS). The highest linear dunes have smaller linear dunes along their crests. Linear dunes are generally aligned parallel to the prevailing winds; these dunes are deflected as they reach the Tsondab River Valley (at top), by strong winds that blow in from the east in winter. This image was taken by a member of the Expedition 47 crew on March 27, 2016. It has been cropped and enhanced to improve contrast, and lens artifacts have been removed.
