NEW: A lot of bad has happened to American science over the last year but nothing comes even close to what’s about to happen if we don’t speak out in opposition to the OMB rule changes and I hope @aaas-socsci.bsky.social @apsphysics.bsky.social and others will launch public campaigns about this. 🧪🔭⚛️

It's the End of American Science As We Know It

We have 45 days to express our opposition to catastrophic changes.

🧵 Public science in the US has taken some heavy hits over the last year, but the White House OMB is proposing a series of changes that will result in a TKO for science as we know it unless we fight back. Here's what's happening, and why it matters. 1/n

While we're talking percentages, let's talk about the proposed cuts to NASA's science budget. NASA is currently 0.36% of US federal spending. www.planetary.org/space-policy... The proposed budget cuts NASA science by 47%. NASA science is already on a shoestring, and that string is about to break

More context on this #Artemis II image: * This is the night side, lit by moonlight. You can see city lights in Spain & Portugal, & a sliver of day at lower right * The Sun is entirely behind Earth, which makes it a kind of solar eclipse, but w/ Earth doing the eclipsing instead of the Moon: ☀️🌍🚀🌕

A full disc image of Earth, as seen from the Orion Crew Module. The planet is a pale blue, swirling with white clouds and glowing slightly lighter blue in place from reflected light. At lower left, a large brown landmass is Africa, with Spain and Portugal with twinkling lights where the planet curves. At top right, auroras glow in a thin green glow, just barely separated from the planet's surface. Earth is set against the black of space (pic: NASA/R.Wiseman)

If all goes according to plan, in a few hours, a crew of astronauts will begin a journey that will take them on a loop around the moon. Here's a video that NASA put together to help people visualize the journey through space, first orbiting the earth before looping around the moon and flying home 🔭

Among the firsts of Artemis II, it will be the first time a person of color and Black astronaut (Victor Glover), first woman astronaut (Christina Koch), and first Canadian and non-US citizen astronaut (Jeremy Hansen) travel beyond low Earth orbit and to the Moon. 🚀

All the news today caused the major outlets to forget that we are taking the first human flight to the moon tomorrow in >50 years! I think about all the wonder & inspiration that came from the Apollo and Voyager missions & how we are missing that now bc of all the terrible things happening. 🔭🚀

Chanda Prescod-Weinstein 🌌@chanda.blacksky.app · 5mo ago

👇🏽 great example of how the NYT continues to — has never stopped — engaging in platforming anti-Black, genocidal rhetoric and how it is so normalized that it is not discussed in those terms (not a criticism of Victor, just noting the way our cultural vocabulary shifts for discussions anti-Blackness)

Victor Ray@victorerikray.bsky.social · 5mo ago

Here is Ezra Klein sitting down with the New York Times resident segregationist. Cadwell quite literally thinks the Civil Rights Movement created a second constitution, damaging white men's right to free association (by which he means excluding Black people from public life).

OSU astro coffee was so fun today! We talked about @clairelamman.bsky.social's Hawking radiation comic, OSU undergrad Mya Smedley presented on how lessons from SpongeBob (kindness, empathy, and passion) can be applied to astronomy, & we saw new XRISM results on M82! arxiv.org/pdf/2603.24674 🔭

Projector screen from OSU astro coffee today during undergrad Mya Smedley's presentation on applying lessons from SpongeBob to our pursuits of astronomy. Title of the slide is "KEP (kindness, empathy, and passion), SpongeBob, and Combatting Groupthink and Apathy". Text says "question of the day: how can we collectively be more like SpongeBob SquarePants? Be vocal in your community never be neutral: CARE; Understanding diversity is unity; Being present in everyday life".

So happy to finally share this: I made a long-form comic about Hawking radiation for Physics Today! Although it's a short read, I hope it sucks you in ;) physicstoday.aip.org/features/bla...

very grateful to have finally made it in person to visit OSU since my virtual Price Prize talk in 2020. thanks to everyone for the invitation and especially @ohdearz.bsky.social for hosting! also love to brag about my awesome grad students!

Honored to have @carlnotsagan.github.io visit OSU today and give an outstanding colloquium on next generation simulations of massive star death & predictions for multi-messenger signals! 🔭🧪⚛️

Looking at the AAS jobregister lately, it seemed to me that there are less positions available in all categories than in previous years. Wanting to quantify, I used the wayback machine to check on the number of postings in the January-March window and it is quite depressing.
