Becquerel Crater

September 9, 2013
A striking scene in and around Becquerel crater – the largest crater in this view – reveals both the power of wind and water in the turbulent history of Mars. A mound of light-coloured sulphate deposits formed from evaporating water sits inside the crater amid a sea of dark wind-blown deposits. The darker material has blown towards the south-southwest (top left) of the image in a wide swath and across tiny craters there – their raised rims protect the material immediately downwind from being swept away. The mosaic is composed of four images taken by the High Resolution Stereo Camera on ESA’s Mars Express, with an average ground resolution of 17 m per pixel. The image centre lies at about 22°N/352°E; North is to the right. The individual images were taken on 22 July 2006 (orbit 3253), and 26 February, 2 and 7 March 2008, corresponding to orbits 5332, 5350, and 5368, respectively. Copyright ESA/DLR/FU Berlin (G.
