Korea’s Kompsat-2 satellite captured this image over the sand seas of the Namib Desert on 7 January 2012. 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 kilometre, 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. In this image, there appears to be some shadow on the western side. From this we can deduce that the image was acquired during the late morning.

The foothills of the Andes mountains near the southern coast of Peru were captured by the Kompsat-2 satellite on 4 May 2011. The Andes stretch about 7000 km from Venezuela down South America’s west coast to the top of Argentina. The mountain rage is the result of the Nazca and Antarctic tectonic plates moving under the South American plate – a geological process called ‘subduction’. This process is also responsible for the Andes range’s volcanic activity.
