Hephaestus Fossae,Mars. This region is dotted with craters and a channel system (going across image). It is thought the channels were formed when the more powerful impacts melted subsurface ice reservoirs. The resultant flow of water eroded channels in the surface. The large crater at left measures 20 kilometres in diameter. Image taken by the High-Resolution Stereo Camera (HRSC) on the Mars Express spacecraft on 28th December 2007 | |
