This image shows a network of dried-up valleys 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 (HRSC) on ESA’s Mars Express during spacecraft orbit 18831. It covers a part of the martian surface centred at 66°E/17°S. North is to the right.
