Hey, all. At the suggestion of long-time member PDP8E this thread has been created for everybody to post their images and animations of dust devils observed by Perseverance. Please be sure to include the sols when taken and times as well if they're available to make this data (and your great work) as useful as possible for any researchers who may take an interest. Thanks!
EDIT: I'll be moving several posts from the Perseverance threads over here to kick it off. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Hmm, time to start naming the dust devils after the members of the band Kansas, perhaps after cities in Kansas, and crowd-sourcing a competition to see which Kansas grade school can count the most?

(I posted this initially to the EDL thread but can't seem to find it now, so here it is for posterity)
Perseverance recorded this DD during descent. Simeon Schmauss spotted this in LCAM footage and produced this stabilized and reprojected view, shown here at 20x real time. The DD is seen moving westward at roughly 8.5 m/s (20 mph) and was estimated to be about 25 m (75 ft) wide. https://twitter.com/stim3on/status/1379575241970683908?s=20 |

That got me and Simeon looking at HiRISE views of this area to see if that might be a transient feature, maybe a DD track. Sure enough, that track was visible in the first HiRISE view after Perseverance's arrival but was not present just six months earlier. That track is ~34m wide. Across this broader HiRISE swath you can see dozens or hundreds of similar transient streaks, some estimated to be ~80m wide, predominantly oriented east/west. This place is a popular playground for these devils! |

Hi Ryan,
Thanks for those DD maps! And a personal thank you for the RoverPics website over on github. Great Job! Karle -------------------- CLA CLL
