This stereoscopic image shows in 3D a slice of Mars that has been imaged to mark a milestone for ESA’s Mars Express: its 25 000th orbit around the Red Planet. It was generated from data captured by the High Resolution Stereo Camera (HRSC) on ESA’s Mars Express orbiter on 19 October 2023. The anaglyph offers a three-dimensional view when viewed using red-green or red-blue glasses.
