Mars’ north polar ice cap in 3D

This image shows shows part of the ice cap at Mars’ north pole 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 3670. It covers a part of the martian surface centred at about 244°E/85°N. North is to the upper right.
