This 3D anaglyph image, taken by the High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express spacecraft, shows the detailed structure of Coprates Catena, a southern part of the Valles Marineris canyon system on Mars.
The image was taken during orbit 438 on 25 May 2004, with a ground resolution of approximately 43 metres per pixel. The displayed region covers an area centred at about latitude 14° South and longitude 301° East.
Coprates Catena is a chain of collapsed structures, which run parallel to the main valley Coprates Chasma. These collapsed structures vary between 2500 and 3000 metres deep.
