NASA's Perseverance Mars Rover

Unless it was a significant amount of dust on the camera lens or the mirror that it uses to look down into the imaging chamber I doubt that it would affect operations at all, as they only use the camera to ensure the sample is still in the tube prior to sealing it. But why else image it without a tube, it appears to be a waste of bandwidth as they acquired and then downlinked 20 tiles in all from the CacheCam. Hopefully the team will enlighten us soon why it was imaged, if not we can wait for the mission managers report in the PDS, those reports of often goldmines of information. The report covering sol 1324 activities should be available in the M2020 PDS (release number 12) scheduled to be issued on April 3, 2025 https://pds-geosciences.wustl.edu/missions/mars2020/index.htm
