Melas Chasma in high resolution

Melas Chasma is part of the huge Valles Marineris rift valley on Mars. Melas Chasma itself sinks 9 km below the surrounding surface, making it one of the lowest depressions on the planet. On 1 July 2006, the High-Resolution Stereo Camera on ESA’s Mars Express spacecraft obtained images of Melas Chasma at approximately 10°S/290°E. The data were acquired during orbit 3195 and this image was derived from the HRSC nadir channel, which provides the highest detail of all the channels.
