I’m glad to share that our PACIS instrument has passed its Preliminary Design Review. This confirms that our instrument architecture and technical choices are robust enough to move into detailed design.

Even if in this particular case the press release is likely a PR operation to bring back MSR to life at a time US colleagues need to lobby the
congress, having these samples back is more than worth fighting for.

New research revealed that Mars' innermost core appears to be a solid hunk of metal just like Earth's.

@umdgeology.bsky.social's Nick Schmerr weighed in on these findings with @sciencex.bsky.social, noting that questions regarding Mars' core are far from settled. 🔭 #PlanetaryScience
Marsquakes indicate a solid core for the red planet, just like Earth

@mhairireid.bsky.social and I put together an article for @theconversation.com about yesterday's @nature.com paper on the detection of a 600 km radius solid core in the interior of #Mars! 🧪🔭 #planetsci
Early InSight results didn't quite have the sensitivity for this!

Propagation of the Aude wildfires in the South of France . Astounding
C’est un véritable désastre écologique dans l’Aude. En à peine 7h, plus de 7000 hectares sont partis en fumée, avec un front de feu de >30km de long. La vitesse de propagation est exceptionnelle : nous assistons probablement au feu de forêt le + rapide et le plus violent du XXIᵉ siècle en France 1/2

The NASA planetary science fleet chart if the president’s budget is enacted.

This is an extinction level budget
The NASA budget req would end NASA's participation in ESA's Rosalind Franklin Mars rover (as anticipated) along with MSR, NASA's two Venus probes (DAVINCI and VERITAS) and coop with ESA on theirs (EnVision), and somewhat surprisingly OSIRIS-APEX and Juno, both already in space.

Cool new paper out. Ryan Park and Alex Berne (with the help of a lot of other co-authors including a tiny role from me) pushed the GRAIL lunar gravity data further than before, notably updating the estimate of the k3 Love number.

After serving as Director of NASA Jet Propulsion Laboratory and VP of Caltech for three years, I have decided to step down, effective June 1. Though not an easy decision, I strongly believe it is the right one for me, my family, and the Lab. www.jpl.nasa.gov/news/dave-ga...

Wow ! Curiosity rover has found compelling evidence of an ancient carbon cycle on Mars—similar to Earth’s, but incomplete. This may change how we think about Mars’ climate history. #Mars #PlanetaryScience
