This stereoscopic image shows Thyles Rupes, one of the most prominent cliff-faces in Mars’s ancient southern highlands. It was generated from data captured by the High Resolution Stereo Camera on ESA’s Mars Express orbiter on 17 February 2026 (orbit 27925). The anaglyph offers a three-dimensional view when viewed using red-green or red-blue glasses.
[Image description: A greyscale image of the surface of Mars, which is slightly lighter on the left and darker on the right. The image is dominated by a small, bright, circular crater at the centre. A small scale bar at the bottom right indicates that north is to the right, and that a line approximately one tenth of the image width is 50 km long. At the top right of the image is an icon of a pair of 3D (red-blue) glasses, indicating that the viewer can see the image in three dimensions when viewing using special glasses.]
