Yesterday Curiosity took pix of jagged peaks in the distance with its ChemCam. I stitched them together, did some work on them, and... just look at that view... I've been doing this since Sojourner landed & this is one of my fave images ever... Credits: NASA/JPL-Caltech/LANL/S Atkinson

Quick & dirty animation of pre- and post-abrasion WATSON photos by #PerseveranceRover on sols 1630 & 1631. Based on treated images by 65dBnoise:

I've been asked a few times over the last few days what I think the chances are that the "leopard spots and poppy seeds" on Mars will turn out to be actual evidence of life. People are naturally skeptical given the history of possible signs of life on other planets. Strap in: long thread ahead...

Today I happened to leave Jezero crater 🙃

After poking around and finding the base of the flow, the story became much richer: the basalt had flowed over some eolian dunes which sourced the water for the hydrothermal system. The sand might have accumulated as obstacle dunes around a bedrock hill, then buried by the flow in a valley. (2/2)

The IAU announced official names for Donaldjohanson's surface & shape features 2 weeks ago, but nobody has mentioned the news. They're all named after archeological sites and hominin fossils, which is fun and awesome haha

(Afar Lobus = small lobe, Olduvai Lobus = big lobe, Windover Collum = neck)

There's a lot happening in that closeup, great color work!

But don't zoom & rotate too much, maybe you get a scare 😬

If you liked the quoted cloudy panorama by @stim3on.bsky.social, there's a relevant current #Zooniverse project: www.zooniverse.org/projects/mat... with #MavenMission UV mosaics.

Not a simple task, but a good one to grasp how much activity there is in the Mars atmosphere.

We saw this in the Mars Map sequence. It shows canals even though most maps of the time had dropped them. So here is my first set of missions which never happened. The oldest is von Braun's Mars Project in 1952/53. 10 spacecraft, 70 crew, the first crew land […]

¿No me digas que he vuelto a poner la pieza mal orientada como las imágenes Watson del otro día? 😅

Exquisite work! 👍 I took the liberty of rotating the 2nd one a bit, it gives a better sense of orientation. The detail and the lightning are great input for seeing how some of the small features that might look like the leopard spots from Cheyava, are probably impact spherules in this case.

This course belongs in a museum! 😉

My 1st run, I went for the science but it specially opened my eyes to the outer solsys. The 2nd, I wanted more Mars background for improving my understanding of Perseverance and it DELIVERED. Who knows a 3rd? 😉

@plutokiller.com Just finished revisiting the lectures of your "old" Planetary Scienc Coursera (took some weeks, mostly while peeling potatoes, don't ask 😉)

It still holds really well, despite references to future missions & telescopes that are now history or ongoing 😀 ...
