Mine was only a proof of concept, so I'm glad someone at NASA made a more refined version. Their version apparently fuses more streams of telemetry to represent the true rover position at very small intervals, while mine was limited to only the Navcam image locations that were interpolated.

Superb video included in today's JPL update for #PerseveranceRover (www.jpl.nasa.gov/news/nasas-p...). With synthetic frames and obviously, the rover doesn't move that fast, but the final result is impressive. Credit: NASA/JPL-Caltech

Unusual “helmet-shaped” rock composed entirely of smaller spherules. This image was taken by NASA's Perseverance rover on Mars. This image is also up for the planetary science image of 2025: bsky.app/profile/spac... NASA/JPL-Caltech/ASU/ @jackiebranc.site #SciComm 🧪

To sum up iopscience.iop.org/article/10.3... - the initial spacecraft astrometry of 3I/ATLAS substantially improves its orbit determination - this helped show that 3I/ATLAS has a significant non-gravitational acceleration & - indicates 3I is significantly less massive than originally supposed.

Cut of the original video with the #3IATLAS cameo. The video is reversed, I find it easier to find it with it going from right to left. Its path starts below the saturated region on the middle right and goes in a slight diagonal towards the left.

Hey #planetSci friends, the end of the year is nearing. Does anyone want to help me put together an Image of the Year Bracket? If you want to propose your favourite planetary science image of 2025, place it below with a link to the source and when it was published.

@wierzchos.bsky.social qué sorpresa encontrarte referido en un paper sobre coatings en Marte, se me había olvidado a lo que se dedicaba tu padre 😉 onlinelibrary.wiley.com/doi/10.1111/... agupubs.onlinelibrary.wiley.com/doi/10.1029/...

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

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 🙃 (mastodon.social/@sharponlook...)

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 😬

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.

North of Las Vegas NV...amazing geology, spectacular scenery, and petroglyphs.

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? 😉 bsky.app/profile/shar...

Besides spookiness, a fine example of a fallen chunk of Rockytop outcrop, with probable coatings of its own category as described here: Theuer et al : "Characterization of Rock Coatings in the Fan Front, Upper Fan, and Margin Units Using Mastcam-Z Data" www.hou.usra.edu/meetings/ten...

What I like the most in these is the row of bright rocks behind the Pico Turquino ridge, still haven't located it on the map though. Right behind that row runs an almost invisible regolith "horizon" and the ridges that show up behind are on the Margin Unit, 3 or so km away. 🤯
