Shut down but not silenced: Federal workers find their voice

After months of layoffs and funding cuts by the Trump administration, the government shutdown has given some federal employees hope that their voices are finally being heard.

Isaacman would be wise to avoid having himself associated with this regime (their continued dismantling of the space agency is reputational poison IMO):

"A bit of technique: To obtain the image of the Martian yardangs, I assembled 12 black and white photos taken by RMI, a small telescope on the Franco-American ChemCam instrument.
I then colorized the resulting mosaic with the lower-resolution Mastcam image, a technique called pansharpening."

Thomas Appéré @thomasappere.bsky.social · 10d

Un peu de technique : pour obtenir l'image des yardangs martiens, j'ai assemblé 12 photos N&B prises par RMI, petit télescope de l'instrument franco-américain ChemCam.
J'ai ensuite colorisé la mosaïque obtenue avec l'image Mastcam à plus faible résolution, technique appelée pansharpening.

The Curiosity rover is currently exploring the Boxworks region and will next head toward the Yardangs."

"Looking for a spot to go rock climbing 🧗‍♂️?
I've got just the thing for you: admire these stunning cliffs on Mars photographed by the Curiosity rover. The one in the center is ~39m high, and with Martian gravity being low (1/3 of Earth's), it'll be easier to climb!"

Thomas Appéré @thomasappere.bsky.social · 10d

Vous cherchez un spot pour faire de l'escalade 🧗‍♂️?
J'ai ce qu'il vous faut : admirez ces superbes falaises sur Mars photographiées par le rover Curiosity. Celle au centre fait ~39m de haut et avec la faible gravité martienne (1/3 de la pesanteur terrestre), il sera plus facile de grimper !

AFAIK, several orbiters from NASA and ESA captured images. ESA images should be released soon, NASA images will unfortunately take until the government shutdown is over...

This is an interesting feature that appears to be a large anticline that is crosscut by wrinkle ridges. Anticlines are folded rock formations that have an upwards convex shape.
