This colour picture was taken by the HRSC camera on board ESA's Mars Express, from an altitude of 320 kilometres. It shows the centre of crater Gusev with the landing site of the NASA Spirit rover (marked). Gusev is a crater of 160 kilometres diameter. Earlier in the history of Mars, it appears that this area was covered by water. Because of the probable existence of sediments from this ‘lake’, Gusev is a highly interesting target in the search for traces of water and life on Mars. The area shown measures about 60 kilometres across at the bottom; North is at the top.
