Nirgal Vallis in 3D

This image shows Nirgal Vallis, a dried-up river valley on Mars, in 3D when viewed using red-green or red-blue glasses. This anaglyph was derived from data obtained by the nadir and stereo channels of the High Resolution Stereo Camera on ESA’s Mars Express during spacecraft orbit 18818. It covers a part of the martian surface centred at about 315°E/27°S. North is to the right.
