Forgot my charger at one of the closest hotels I stay... Took me almost an hour to go back get and come back :)

Shout-out to @alexwitze.bsky.social for being included in @merriam-webster.com's definition for "heliophysics" (which has long been a word, but is now a *recognised* word)

#AGU25 starts tomorrow! I'll be around all week! Hope to see many people there and catch up👋!

NASA Selects Two Heliophysics Missions for Continued Development - NASA NASA has selected one small explorer mission concept to advance toward flight design and another for an extended period of concept development.

NASA just selected @jhuapl.bsky.social Developed CINEMA Mission! www.nasa.gov/news-release... ! 🥳

NASA Selects Johns Hopkins APL-Developed CINEMA Mission to Study Space Weather CINEMA, a mission to improve understanding of the growing impacts of space weather, has been competitively selected by NASA for development.

NASA has selected Dartmouth College and Johns Hopkins APL to begin development on CINEMA, a mission to improve our understanding of the growing impacts of space weather. https://jhuapl.link/8cb

This is how it feels right now...

A huge thanks to all participants for making the 3rd LMAG25 workshop a success! For anyone who wants to revisit the talks: The final program & presentation recordings are now available on our site: www.lmag25.com/presentations

Yesterday I joined remotely a space weather AI/ML panel at #ESWW2025 in Umeå as a giant face on a screen.

Key takeaways: We need less hype, more rigor. Better validation, standardized benchmarks, and open access to models/data. Hope to join in-person next year😀!

Thanks!

Heading to Lisbon for #IAGA2025!

I'm giving three talks:

• Mon 17:15 (C.2.22): Particle acceleration at bow shocks
• Tue 11:45 (C.3.7): Storm-time plasma sheet convection
• Tue 16:30 (C.2.22): An update from the #NASA CGS drive center

Come say hi if you're around!

Very hard to choose one! For Movies, I have a top 3 I remember as kid that I'd love to rewatch everytime! Home Alone, Matilda and Groundhog Day!

Subcommittee Markup of the Commerce, Justice, Science, and Related Agencies Appropriations Act | United States Senate Committee on Appropriations United States Senate Committee on Appropriations

🧪 BREAKING (good news): Senate subcommittee says NO! to Trump's proposed slashes to NASA & NSF funding.

Today, the subcommittee said to keep NASA + NSF funding at $33.9 billion, the same as in FY24.

See 7:15 below. Full Senate appropriations committee meets tomorrow about it.

Just came back from NSF/GEM 2025 last week in Iowa, Des Moines (gemworkshop.org)! Exciting talks, new ideas, and the launch of our focus group on Multiscale Dayside Transients. Had a great time with friends and colleagues and already looking forward to next time!

Coming soon: JourneyMon: Monster Trainer Roleplaying A narrative, collaborative world-building TTRPG about friendship and monster battles.

I'm excited to announce my passion project JourneyMon: Monster Trainer Roleplaying is coming soon to Kickstarter!

Be sure to follow our pre-launch page to keep up to date with the latest news!

NASA begins push to slash workforce with more staff buyouts, early retirements as budget cuts loom NASA employees have until July 25 to decide if they'll stay or go.

NASA Goddard is pushing through a 48% staff reduction!!! This could impact the upcoming Roman Space Telescope and many other future Astro missions. News coverage seems not sensational enough. Are we really going to let NASA (as we know it) die quietly? www.space.com/space-explor...

You've heard about the catastrophic cuts to U.S. scientific leadership the Trump Administration has proposed.

This chart from Joshua Weitz (joshuasweitz.bsky.social‬) shows just how bad it is—funding levels for NASA, NSF, and NIH so low as to destroy science in America.

Inspired by @jtuttlekeane.bsky.social and @ohdearz.bsky.social, here's what the White House proposed budget cuts to NASA would do to the entirety of the agency's Science Mission Directorate.

Bloodbath is right.

I'm a current Harvard graduate student and I found out today that I had my NSF GRFP terminated without notification. I was awarded this individual research fellowship before even choosing Harvard as my graduate school

Had a fantastic week in Paris celebrating the 10th anniversary of #NASA's Magnetospheric Multiscale (MMS) mission 10thmmsanniv.sciencesconf.org !

The workshop featured excellent talks and discussions! Looking forward to next year’s gathering!

Great week at @iwf-oeaw.bsky.social, reconnected with friends and colleagues and had insightful discussions. Thanks for hosting! Looking forward to my next visit and to seeing you in Paris next week for the #MMS Anniversary Workshop. #Heliophysics #Collaboration

Our collisionless shocks session at #EGU25 drew a great crowd, sparked insightful discussions and set the stage for new #heliophysics collaborations. Thanks to everyone that attended!

Arrived in Vienna yesterday for #EGU25! Ready for a week of #Heliophysics, science chats, and reconnecting with colleagues and friends. Let’s grab coffee if you’re around! Find more information about the program www.egu25.eu and if you are around, please come to my talks and presentations to chat!
