NASA is moving forward with support for ESA’s Rosalind Franklin rover mission to Mars! The ROSA project will provide the launch (SpaceX Falcon Heavy), propulsion for the lander, radioisotope heaters, specialized electronics & parts of the life-detecting instrument science.nasa.gov/blogs/mars-r...
NASA Begins Implementation for ESA’s Rosalind Franklin Mission to Mars - NASA Science
NASA has given approval for the agency’s Rosalind Franklin Support and Augmentation (ROSA) project to begin implementation, underscoring the agency’s

The FY 2027 NASA budget request hides its science cuts by omitting mission names instead of explicitly zeroing them out. We did the work and found 54 missions cancelled in this proposal. This is another extinction-level event for NASA science. Full list: planetary.org/save-nasa-science

The super-Earth trap: why "Rocky" civilization may have never reached the stars
How a blockbuster movie, the tyranny of the rocket equation, and a little-known 2018 paper illuminate one of the most sobering ideas in astrobiology.

Roger-Maurice Bonnet, l'ancien directeur du programme scientifique de l'ESA entre 1983 et 2001, est décédé le 19 janvier à l'âge de 88 ans. Astrophysicien, il a participé aux missions Giotto et a approuvé les missions SOHO, XXM-Newton, Rosetta, ... www.esa.int/About_Us... 1/2
This really matches my impression.
Alexandra Witze@alexwitze.bsky.social · 8mo agoAttendance at US-based science conferences is bouncing around this year but generally down. #AGU25 has ~10k fewer this year! I explored these trends for @nature.com — including solutions to keep conferences local & productive: www.nature.com/articles/d41... 🧪
Finally at #AGU25 ! Presentation of Philippe Lognonné of its network of telescopes to detect Moon impacts
The National Academies just dropped the Science Strategy for the first human campaigns on the Red Planet. It’s not just a flag-planting trip; it’s a deep dive into the unknown. The science is bold, and the challenges? Absolutely immense. Let’s break it down! 🧵👇 #MarsScience #PlanetaryScience

David Mimoun@moonnext.bsky.social · 8mo agoGreat news for lunar science! 🧑🚀🌓🚀 NASA has selected the SPSS payload for the Artemis IV mission (2028) It will be deployed near the Moon’s South Pole to record moonquakes and reveal the deep interior. A proud international effort led by JPL! #ArtemisIV

The Bernard Lyot Telescope (TBL, diameter 2m), located on the observation platform of the Pic du Midi de Bigorre (Alt 2877m) is a national telescope. It is managed by the Observatoire Midi Pyrénées
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.
Back to science ! Start of the SuperCam week in sunny Saint Lary, French Pyrenees. Let’s talk about Perseverance results
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. www.nasa.gov/news-release...

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

@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! doi.org/10.64628/AB....
Mars has a solid inner core, resolving a longstanding planetary mystery — new study
It turns out that Mars has a similar interior structure to Earth.
