This 3D image, best viewed using red-green or red-blue glasses, shows Chalcoporos Rupes, a region on Mars that shows signs of dust and wind activity.
This anaglyph was derived from data obtained by the nadir and stereo channels of the High Resolution Stereo Camera (HRSC) on ESA’s Mars Express during spacecraft orbit 18983. It covers a part of the martian surface centred at about 23° East and 53° South. North is to the right.
