From lake deposits to fluvial floods at the eastern delta front of Jezero crater, Mars
Abstract
The Perseverance rover landed on the floor of Jezero crater on 18 February 2021. The landing site is located ~2.2 km from the SE-facing erosional scarp of the western fan deposits. Images obtained using the Mastcam-Z camera and the Remote Micro-Imager (RMI) of the SuperCam instrument provided the first Mars ground-based observations of this western fan. These images show a deltaic architecture consistent with a paleolake, but at a level ~100 m lower than expected, suggestive of a closed system [1]. Here we report new observations made during the “rapid traverse” in March-April 2022, a period during which the rover traveled fast along the eastern and southeastern side of Jezero fan taking only a few remote sensing observations on the way.
