paulhammond5155@lemmy.worldto NASA's Perseverance Mars Rover@lemmy.world•Cloudy mid-afternoon, summer, on the plateau (UPDATED)English2·15 days agoHere’s a processed tiled mosaic by Simeon Schmauß
Perseverance rover captured this afternoon view of clouds above the Nili Planum region on Sol 1584.
The raw images from the left and right Navigation camera were undistorted, leveled and stacked to reduce noise. The resulting image was then color calibrated and white balanced to approximate what the human eye would see on Mars.
Additional processing was applied to reduce some glare that stems from dust on the camera lens and the sky was enhanced slightly to bring out the detail of the clouds.

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
I totally missed that dust devil… (Old eyes were concentrating on the tracks)
One of the guys I followed on Mastodon left after the federated server when it closed down as he mistakenly believed that Mastodon was closing down, when all he had to do was to move to another server. His processing abilities were top notch in general, but especially for those feint dust devils. Both rovers do regular time lapse surveys for dust devil, most are very feint and take an extraordinary amount of processing. He’s now posting on BlueSky, I will try and go there more often and check out what he’s up to. Those post sunset high elevation clouds make lovely images.
I assume there is a ton of information in the appearance of wheel tracks that can be translated into rogolith behavior. When I first saw the previews of that NavCam on AeroBrowser I mistakenly assumed the transition was at a tile boundary, but it’s nowhere near, so it’s real :)
I use AeroBrowser to download the image sets after each drive as it downloads them is zip file sets with all all the tiles (left and right) along with a json text file each image. Having the zip files makes for simple assembly of the post-drive images.
Talking of images, I always assemble the raw L-NavCam tiles (after each drive). I assemble them as JPEG’s, so they are quicker to upload and meet upload limits. I don’t retain them after I have posted them to social media, as that would need a lot of storage that I don’t have. If you want I could send you the assembled raw L-NavCams as soon as I assemble them. That would save you a little time after each drive. DM sending images via Lemmy has some issues, but I should be able to use Discord or maybe by email. Let me know if you want me to start sending :)
