Huygens Crater Rim
October 20, 2004
This image of the eastern rim of the Martian impact crater Huygens was taken by the Mars Express spacecraft. The displayed region is centred around longitude 61Â° East and latitude 14Â° South. The crater rim is heavily eroded and shows a â€˜dendritic' pattern. This observation suggests surface water run-off.The valley system is blanketed by dark material, which was either transported by a fluid running through the channels or by wind-driven (â€˜aeolian') processes. Part of the area has been covered by slightly redder material, which implies a different chemical composition.
