| Description: |
Since Landing in Jezero crater, the Mars 2020 Perseverance rover has encountered light-toned float rocks (“float”) scattered across the crater floor and Jezero delta, with recent observations suggesting that they may also be present on the crater rim. In total, over 4,000 candidate light-toned float have been identified in Mastcam-Z images as mostly gravel to pebble grain size, but occasionally present as sand and small boulders. To date (Sol ~1000), no outcrop of these light-toned float has been found. Here, we report on their discovery and use imaging, chemical, and mineralogical data from the SuperCam and Mastcam-Z instruments onboard the Perseverance rover to constrain the potential origins of these unusual float. |
