This image shows an area close to the landing ellipse for NASA’s Mars 2020 Perseverance rover, which is expected to land within Jezero crater on 18 February 2021. Jezero crater was once the site of a lake, and the landing site is centred on an ancient river delta near the rim of the crater. Although the actual landing ellipse is just outside of this image, it was taken as part of an imaging campaign to study the rover's future neighbourhood, in preparation for its arrival.
The image was taken by the CaSSIS camera on the ESA-Roscosmos Exomars Trace Gas Orbiter on 30 April 2020. The image measures about 3 x 15 km.
