This image shows a region of Mars known as Caralis Chaos in wider context. Copious water is thought to have once existed here in the form of an ancient lake. This lake would have filled the flatter regions labelled Ariadnes Colles, Caralis Chaos, and Atlantis Chaos.
The area outlined by the larger white box indicates the area imaged by the High Resolution Stereo Camera aboard ESA’s Mars Express orbiter on 1 January 2024 during orbit 25235, while the smaller white box shows the part of the surface featured in these new images.
