Europa Clipper Captures Mars, Phobos, and Deimos NASAs Europa Clipper captured this infrared image of the heat radiation from Mars and its moons Phobos and Deimos on Feb. 28, 2025.

Another cool result from the #Clipper flyby of #Mars, with this infrared image of the Red Planet with its two moons, Phobos, and Deimos!

Un autre résultat intéressant du survol de Mars par notre sonde Europa Clipper, avec un cliché infrarouge de la planète et ses deux lunes, Phobos et Deimos!

NASA’s Europa Clipper Radar Instrument Proves Itself at Mars - NASA The agency’s largest interplanetary probe tested its radar during a Mars flyby. The results include a detailed image and bode well for the mission at

Very exciting to see Clipper’s radar instrument REASON perform well during the Mars flyby a few months ago! Imagine what we’ll learn about #Europa’s subsurface!

Le radar de #Clipper a bien fonctionné lors du survol de Mars il y a quelques mois, prometteur pour l’étude d’Europe!

The Presidents Budget Request for NASA is out. It’s a bloodbath

Canceled are DAVINCI, VERITAS, Juno, OSIRIS-APEX, US participation in ExoMars and EnVision…

Huge cut to R&A. No funding to begin development of the Uranus Orbiter.

If you’ve ever cared about NASA, time to contact congress.

You have three days, starting today, to leave a public comment with the FDA about, say, why COVID-19 boosters should remain available to everyone and also free. "Individual consumer" is the category you most likely want (unless you are one of the other categories; if so, choose that).

Please reach out to your elected officials to ask them to protect NASA’s funding for planetary science, in whatever way you can!

Origins Uncertain: ‘Skull Hill’ Rock - NASA Science Written by Margaret Deahn, Ph.D. Student at Purdue University

Cool rock found by the Perseverance rover on Mars!

Promising hints of life found on distant planet K2-18b Scientists find new but tentative evidence that a faraway world orbiting another star may be home to life.

Very exciting results from observations made with JWST!

NASA Needs Your Help! NASA is facing severe budget cuts that would cancel missions ready to be launched, put tens of thousands out of a job, and set science back decades. We need your help to ask congress to prevent these ...

Did you know NASA science is facing a 50% budget cut??? Please read this @astrobites.bsky.social post to learn more about it and what you can do astrobites.org/2025/04/15/h...

Today, it has been 6 months since Europa Clipper launched from Kennedy Space Center, shortly after hurricane Milton caused havoc in the region.
The spacecraft has been doing great ever since!

Cela fait maintenant 6 mois qu’Europa Clipper a été lancé depuis le centre spatial Kennedy!

I didn’t have earthquake on my bingo card as flight director for Europa Clipper this morning! Glad the early warning notification worked and luckily the shaking on the 4th floor of our mission control was very limited.

Got a cool new Clipper patch this week!
Un nouveau patch Clipper sympa !

Today we are five years away from Europa Clipper’s arrival at Jupiter on April 11, 2030.

Are you ready for exciting discoveries about Europa, an icy moon that might harbor life in its subsurface ocean? 🤩

Nous sommes à 5 années de l’arrivée d’Europa Clipper a Jupiter !

Thank you Senator @mathildeollivier.bsky.social for visiting JPL and having a discussion with French scientists and engineers!

Merci à notre sénatrice Mathilde Ollivier de nous avoir rendu visite à JPL et d’avoir échangé avec les chercheurs et ingénieurs français !

Did Mars harbour life? One of the strongest signs yet is spotted in a peculiar rock The intriguing chemistry of a rock collected by the Perseverance rover could trace to microbial activity — or not.

Things are getting exciting! Get the samples back to Earth! 🤩

Awesome documentary in French about the history of JPL! By @astrovicnet.bsky.social

Superbe documentaire sur l’histoire de JPL à travers les mouvements géopolitiques! Bel hommage à toutes ces missions interplanétaires qui font rêver (Voyager / Pathfinder m’ont poussé à travailler dans le spatial!)

Good luck SphereX and PUNCH for the launch tonight! 🚀

When your kids ask you what you did to save US science in the crisis of ‘25, you will say that you showed up! Please spread the word and join us!!

If this is true, then I’m very worried for the future of JPL. 😬

Happy to celebrate the hard work of the teams involved in the SphereX and Lunar Trailblazer missions, with this awesome poster.

Now that the Mars flyby of Europa Clipper was successful, the team is starting the preparations for a “cleanup maneuver” scheduled later this month, which will put the spacecraft in a good trajectory to fly by the Earth next year!

We are experiencing an assault on science unparalleled by anything I’ve seen in my life. It’s not one issue or another anymore, the entire institution is under attack by the most powerful individuals in the country.

This Friday, where will you be?

Reporting as Flight Director today for Europa Clipper: impressed by the amazing work the team has done to prepare and execute the Mars Flyby. It’s always cool to see all the plots from telemetry match the predicts! Go Clipper! 🛰️

Congrats to the Blue Ghost team for this successful landing on the Moon!
