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.

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.

Jones et al: "Is the Bright Angel formation a valley-confined lacustrine succession?"

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!
