      It is possible, as the rover is heading for Bright Angel (BA) it’s the west of the current location. This float rock could be from Bright Angel, so could have been washed down Neretva Vallis by floods etc ~3 billion years ago. BA appears to the white in the HIRISE images, BA is thought to be the oldest rocks the rover will encounter and probably predate the impact that formed the crater, so they could be of volcanic origin… Watch this space

      Edit. fixed typos

        Dang, that’s super cool. I’m just a boring regular geologist and had no morphologic context, just guessing based on looks. Thank you for the additional information :).

          You’re most welcome. I’ll post any updates from the science team, but they are fairly rare
