You like Mars? Of course you do, you wouldn't be following me otherwise (or would you? 😏)
Anyway, here is the treat : a ready-to-follow list of other amazing Martians, only one click away. What are still waiting for? 👇

Took a first pass at making a Mars-specific scientist starter pack. I know there are tons of people not on it, so please let me know who to add. #planetaryscience

New paper on Prow I was happy to contribute to from @mars-cat.bsky.social :)
Always happy to see more Prow and can't wait to write my own with ChemCam data!

Awesome imagery captured two days ago by Curiosity, from its location within a trough of the boxwork structure. This is part of a larger, 360° Mastcam panorama.

I think Perseverance may have spotted interstellar comet 3I/Atlas last night from Mars!

After stacking 20 images from Mastcam-Z, I found a faint smudge of light in the constellation Corona Borealis close to the location where the comet was expected. 🔭

image of the night sky showing a starfield with several dark and bright stars that are quite elongated due to the long exposure time. the stars of the constellation corona borealis are annotated in green. a faint smudge, perhaps comet 3I/Atlas is marked with a red circle.

A recent vista from Mars obtained by the Perseverance Rover on its 1635th Martian day, or 'Sol', Clouds far above the eternal dust pall are unusually well shown in this afternoon view. This is a mosaic of two wide angle color Navcam images.
This mosaic of two wide angle photos from the Perseverance rover shows the Martian surface stretching into the distance beyond two foreground hills. The rover tracks can just be seen winding into the distance. In this view clouds are unusually well defined as they float well above the tan dust that eternally colors the Martian skies. In the original photos the area near the Sun is 'burned out' by the limitations of the camera sensor. I have addressed this by manually painting over the overexposed areas to reconstruct something of the brightness contours as they probably would have appeared to a human observer. I have also 'warped' the lower corners to fill the rectangular format. Artist's prerogative :-)

These two mosaics are mine (my pointing and my current investigations) . They were not supposed to be stitched together because of paralax, but that works 😍

Check out the view from up here! As the Curiosity rover continues to climb the flanks of Mt. Sharp, it has captured an extraordinarily clear panorama of Gale Crater's rim...and even the lands beyond. Details:

The full version of this mosaic (in "white-balanced" colours) is now available on the JPL Photojournal: photojournal.jpl.nasa.gov/catalog/PIA2...

(You'll definitely want to click the link to fully appreciate the incredible detail!)

Image credit: NASA/JPL-Caltech/MSSS
A long panorama of the northern rim of Gale Crater on Mars as viewed by the Curiosity rover's colour Mastcams. The image has been white-balanced to approximate Earth-like conditions, so the sky is a pale blue, while the ground is a pale pink/red. Several nearby buttes are visible at the two sides of the image, and the terrain slopes down towards the crater floor. The crater wall rises in the far distance, made slightly hazy by dust in the air.

While at CDS, the Aladin project mainly deals with deep sky images, we also map planetary surfaces.

We released the HiPS of China's Tianwen-1 MoRIC images, a true-color map of Mars at 76m resolution.
