He/Him. Prof. at the University of Michigan's Climate and Space department. Space scientist. Connoisseur of dumb humor. Opinions and stupid jokes are my own.
Two things from my end:
Here at Umich, we've wound up the SWMF to do a real-time run with our latest research version of the model. I'll post some synthetic aurora as the run evolves.
We are also testing a ground magnetometer about 20 miles outside of Ann Arbor. I'll share preliminary data!

Congrats! Well deserved!

...so it was super neat to see this outsider overview reflect what I see when I'm there- the "scars", but also the excitement and growth.
Also, go lions.

I am genuinely happy that, as a lions fan, we have @arif.bsky.social to help us through this crappy Xmas day game. #goloins

However, the shifts on NSF programs and priorities is also disturbing. Critical programs are being "archived" (effectively shut down). Many programs are being consolidated without expanding available funding. The science productivity of the US is about to plummet, and we'll be worse for it.

The news concerning tearing apart NCAR is especially distressing- it's a dangerous precedent to end one of the world's most successful, productive centers because their findings on the climate are inconvenient.

Eric's point - that we are desperate for leadership and Isaacman seems qualified and ready - has been our perspective for months. We were devastated when his nomination was pulled and excited that it's back because our need for stable, competent leadership is so dire.

We don't know what missions will be funded.
We don't know what science will be prioritized.
We don't know what, if any, funding opportunities will be available.
We don't know who to talk to change anything.
We don't know what to tell students who are worried about their future in science.

NASA guides so much about what the space community does- especially outside of NASA, both in science and engineering. Funding agencies such as NSF often look to NASA's priorities to set their own.
Speaking for the science community, "Uncertain" doesn't even begin to describe the ongoing situation.
