On 2 May 2004, the High-Resolution Stereo Camera (HRSC) on board the ESA Mars Express spacecraft obtained this image from the central area of the Valles Marineris canyon, called Melas Chasma.
This image was taken at a resolution of approximately 30 metres per pixel. The displayed region is located at the southern rim of the Melas Chasma, centred at Mars latitude 11° S and Mars longitude 286° E. The images were taken on orbit 360 of Mars Express.
This perspective view was created by using the nadir (vertical view) channel and one stereo channel of the HRSC to produce a digital model of the terrain. Please note that image resolution has been reduced for use on the internet.
