Finding Mars and other worlds on Earth

epa04111824 A handout image made available by ESA and the Korea Aeropspace Research Institute (KARI) on 06 March 2014 and taken on 07 January 2012 shows the Namib Desert, Namibia, taken by South Korea's Kompsat-2 satellite. The blue and white area is the dry river bed of the Tsauchab. Black dots of vegetation are concentrated close to the river's main route, while salt deposits appear bright white. Running through the river valley, a road connects Sossusvlei to the Sesriem settlement. At the road's 45th km, seen at the lower-central part of the image, a white path shoots off and ends at a circular parking area at the base of a dune. This is Dune 45, a popular tourist stop on the way to and from Sossusvlei. There appears to be some shadow on the western side. From this we can deduce that the image was acquired during the late morning. EPA/KARI/ESA
