This image comprises data gathered by Mars Express’s High Resolution Stereo Camera (HRSC) on 28 October 2024 (orbit 26287). It was created using data from the nadir channel, the field of view aligned perpendicular to the surface of Mars, and the colour channels of the HRSC. North is to the right. The ground resolution is approximately 17 m/pixel and the image is centred at about 36°N/230°E.

Image description: The image shows a patch of Mars that is broadly tan in colour and covered in geological features. These are labelled by six numerical markers to give additional context. Most prominently, a system of deep grooves begins in the right half of the image and radiates outwards, extending out of frame. A smoother, irregularly shaped patch of ground can be seen in the middle third of the image, while further ridges and ditches – more gentle than those to the right – are again visible in the left third, along with a few scattered circular impact craters.
