There sure is going to be timelapses, but here's a teaser with some SVT footage that wasn't affected by the hard winds, at something like 15x speed.

Looks like the engineer decided to pray now that the worst part is coming 🙃

viendo el nombre de la observación, serán los KBO que querían localizar no?

Back to #JezeroRimScience, continuing from post nr 5 in the thread. Paper on what SuperCam detected on the inner rim ridges, multitude of possible explanations, more work needed.

Interrupting my sequential traverse of abstracts; one thing lead to another and I ended up looking at the #LeopardSpots (+ "poppy seeds") papers, with "strong" wording for potential biosignatures.
Look at the much longer author list of this first one:
Hurowitz et al: "The Detection of a Potential Biosignature by #PerseveranceRover"
https://www.hou.usra.edu/meetings/lpsc2025/pdf/2581.pdf
A total of 4 related presentations in the Astrobiology session

First on the #JezeroDeltaScience list: stratigraphy analysis of Bright Angel on both channel "shores". Interesting clues and puzzles on the southern side.

Not what I was expecting, they looked too small to me. I was almost sure it was wild boar (because of other bones around), maybe deer, but the latter I can see now that nope. I'll look at it closer later, gracias!

looks too "rounded" imho. Have you a special layer or smth in QGIS for registering where all these are found (there seemed to be more in Mt Washburn)?
