For the less technically minded among us...Ryan Kinnet has put up a page that grabs a listing with links to the PNG files that you can then use any browser-plugin-batch-downloader with
https://twitter.com/rover_18/status/1364309922167488512 I tried Firefox with 'DownloadThemAll' and it worked perfectly. Meanwhile THIS GUY has python code to also grab the data https://twitter.com/kevinmgill/status/1364311336000258048 |

Speaking of raw images, are these weird colorations due to something wrong with the pipeline or the cameras themselves (I'm thinking and hoping it's the former)?
Examples attached, one is a NavCam-L from yesterday (seems to have been pulled since), the other an RDC frame. -------------------- |
