This stereoscopic image shows the southern flanks of Ascraeus Mons, the second-tallest volcano on Mars. It was generated from data captured by the High Resolution Stereo Camera (HRSC) on ESA’s Mars Express orbiter on 15 January 2023 during orbit 24045. The anaglyph, derived from data acquired by the nadir channel and one stereo channel of the HRSC, offers a three-dimensional view when viewed using red-green or red-blue glasses.
