This stereoscopic image shows Aganippe Fossa, a snaking groove found at the foot of Mars’s giant Arsia Mons volcano. It was generated from data captured by the High Resolution Stereo Camera (HRSC) on ESA’s Mars Express orbiter on 13 December 2023 during orbit 25189. The anaglyph offers a three-dimensional view when viewed using red-green or red-blue glasses.
[Image description: This black-and-white rectangle of Mars is bumpy and irregular in the left half, with numerous small mounds clustering together and a number of jagged grooves and ridges seen throughout. The right half of the frame is smoother and marked by zebra-like stripes, a result of windblown dust. A dark scar, reminiscent of a dashed line, emerges from the bottom-middle of the image and arcs round to the middle-right; this is the long, narrow feature of Aganippe Fossa. A small pair of 3D glasses at the top right indicates that this image can be seen in 3D.]
