Last night was my last shift as Flight Director on the Europa Clipper mission. I am going to miss this amazing team and this impressive spacecraft, but I will keep with me the wonderful memories we made during these 10 years of work together. Can’t wait to see Clipper at Europa in a few years! 🥹🛰️

Super grateful I got to see this incredible solar eclipse in Europe. The heat in Zaragoza was intense but the wait was definitely worth it. Tres heureux d’avoir pu profiter de cette éclipse de soleil incroyable. La chaleur à Saragosse était intense mais l’attente en valait la peine ! #eclipse2026

Solar conjunction for our Europa spacecraft is now over! While we did not uplink commands for about 10 days, we were getting some telemetry confirming yhr health of the vehicle. The team is now back in the driver seat! To check out the current location of Clipper: eyes.nasa.gov/apps/solar-s...

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).

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.

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 !

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!

None of us can be sure what will “work.” You try multiple things and find your way in. Read some histories of the Civil Rights Movement by those who participated. They were never “sure” of what would work. Some campaigns fizzled out. But persistence, creativity, determination, and focus were key.

Last week we uplinked the sequence that Europa Clipper will execute to perform the Mars Flyby planned for this week! Look how close (884km!) to Mars the spacecraft will fly: eyes.nasa.gov/staging/apps... This will also be our first eclipse since launch and will last for 51 mins!

Four years ago, our fierce #Perseverance rover landed on Mars. In the midst of an unprecedented pandemic, we were all reminded - even if temporarily - of what can be accomplished when we all work together. Here’s to many more years of exploration and discovery on the Red Planet. Merci! 🤩🎂

Crazy to think that it already takes us almost 10min to talk to Europa Clipper and hear back from it due to its distance from us! (What we call the Round Trip Light Time)
