Martian landslides. Coloured satellite image of landslides (upper middle to lower right) in the Ganges Chasma region of Mars. The Ganges Chasma is a deep canyon in the huge Valles Marineris system on Mars. The right wall of the ridge has a series of terraces (pale transverse lines) which is where large portions of debris have collected into an 'apron' during a landslide. Image obtained by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter (MRO) on 22nd May 2009. The width of this image is roughly 1.1 kilometres across.
