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

Great 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

Happy Thanksgiving 🦃🍁 to those who celebrate!

“Next year Voyager 1 will be one light-day away from Earth”

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

The Pic du Midi Observatory is a magical place

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.

Around the Moon and back next February? arstechnica.com/space/2025/0...

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...

#Mars #InSight Data from defunct NASA lander paint a radical new picture of Mars’s interior ➡️ Studies identify a solid inner core and buried remnants of giant impacts 🧪 #PlanetSci www.science.org/content/arti... @science.org

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

@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....

Propagation of the Aude wildfires in the South of France . Astounding

Here’s a little mission design I’ve been working on behind the scenes these past few months for exploring Mars with a small fleet of helicopters! www.youtube.com/watch?v=GqAu... #planetsci #nasa

Happy to be here at international planetary probe workshop IPPW25

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

Obviously any civilization on this planet will have a hard time getting to orbit with any possible kind of chemical propulsion rocket

According to @arstechnica.com The Trump administration’s FY2026 budget proposal significantly reduces NASA’s science budget—by over 50%. The most affected domain: Planetary Science, with multiple high-priority missions facing deferral or cancellation. arstechnica.com/space/2025/0...
