This view was generated from the digital terrain model and the nadir and colour channels of the High Resolution Stereo Camera on ESA’s Mars Express. It shows a bird’s-eye view of Thyles Rupes, one of the most prominent cliff-faces in Mars’s ancient southern highlands.
This cliff is both broken by and sits atop a variety of impact craters, as seen here, indicating that some craters are older and some younger than the cliff. The largest crater visible here, sitting to the right of the frame, is ancient, having been sliced through and partially covered by Thyles Rupes since its creation. The two smaller craters, which sit atop both this large crater and Thyles Rupes itself, are younger.

[Image description: A pink-grey-coloured patch of Mars. A ridge cuts across the frame, from lower left to upper right. The ridge appears to cut through a large, grey crater, of which we only see two thirds. Another sharper, smaller crater lays on top of the ridge; this crater appears newer. Overall, the landscape has a soft, bumpy and barren appearance.]
