Earth from space: Dune 45

The Namib is the oldest desert in the world, stretching over 2000 km along Africa’s southwestern coast from Angola, through Namibia to South Africa. Sand dunes dominate the desert – some reaching over 300 m in height.

The blue and white area is the dry river bed of the Tsauchab – which only sees water following rare rainfall in the Naukluft Mountains to the east. 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.

“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.”

Schöner als jedes Sandbild: Die Namib ist die älteste Wüste der Welt und dehnt sich über 2.000 Kilometer entlang der südwestlichen Küste Afrikas aus. Sie reicht von Angola, durch Namibia bis nach Südafrika. Bis zu 300 Meter hohe Sanddünen dominieren die Wüste. Blau-weiß zeichnet sich das Flussbett des Tsauchab ab, durch das nur nach starken Regenfällen Wasser fließt.
