Uranus Orbiter and Probe: Mission Challenges and Concept Updates Since the Origins, Worlds, and Life Decadal Survey astrobiology.com/2026/06/ura… #astrobiology #exoplanet @hbhammel

Dragonfly IPO (Integration and Production Operations) underway! 😉

These my @NJGov people 🤘

The future of exploration will be built through thriving spaceports, reusable rockets, orbital assembly, and technologies we once only imagined. Just as railroads and highways transformed our economy, tomorrow’s orbital and lunar economy will help power what comes next. Very exciting times ahead.

Immensely disappointed in my city govt @PasadenaGov

Captured by Anduril's network of 400 telescopes deployed around the globe: The second stage of the Falcon Heavy launch of ViaSat 3-F3 performing a routine thrust event. This produced a spiraled-shaped plume effect, a nominal part of operations for a successful launch of Viasat's latest satellite.

We are going to run out of wild fish in my life time (probably within a decade). I want my future kids to be able to be able to try good fish on occasion. Our greed is stripping the world of its biodiversity… and for what? All you can eat sushi?

"super federal tweet" is so funny lmfao. i'm asking people to contribute to the common good.

I’m pretty sure we stopped doing that

There is a lot going on right now on the @Space_Station, but fortunately we are all safe and witnessed a spectacular southern aurora show yesterday thanks to a recent solar event.

Trump is escalating his war on science. He’s proposing to empower his MAGA cronies to decide what science does or doesn’t get funded. No more actual scientists guiding these critical decisions. It’s now all about the politics. This proposed fundamental change threatens to destroy U.S. global science leadership, which is already reeling after Trump took a wrecking ball to federal science agencies, gutted public health infrastructure — just in time for Ebola & Hantavirus — & slashed research grants to universities. This is why we’re fighting so hard to advance our California science bond. As we fight the gutting of federal science, let’s ensure California triples down on its own global science leadership. npr.org/2026/06/03/nx-s1-584…

The White House’s Office of Management and Budget just proposed new rules that would let political appointees, not scientists, decide which research gets funded in the United States. Under these rules, a senior political official would have to personally approve every single federal grant before it goes out. Peer review, which has been the gold standard for evaluating science on merit, would be reduced to just a suggestion. And if your research falls out of political favor? Any active grant can be revoked at any time, with no explanation required. We're talking about NASA grants, NSF grants, the funding that powers discoveries about our Universe and our planet. This rule was not written by NASA's leadership, and it works against the agency's own exploration goals for the Moon, Mars, and beyond. The rules would also ban entire categories of research outright, and cut off collaboration with scientists from other countries, even if those researchers live in the U.S. Researchers wouldn't even be able to use grant money to publish their findings or attend scientific conferences without getting special permission first. This affects everyone from PhD students to career scientists to all of us whose lives improve because of federally funded research. The public comment period is open right now, but this time, we're not asking you to sign a form letter. We need your actual words, your story, to make a difference. Identical submissions get counted as a single comment, so the more you write, the less OMB can ignore us. We cannot stress how dangerous this rule would be if enacted. But we can stop this if enough people submit their personal story of why peer-reviewed science is important. The deadline to submit comments is July 13th. planetary.org/advocacy-actio…

First US test of modular reactor reaches criticality arstechnica.com/science/2026…

DOGE didn't make a dent in the deficit, but it did bring back screwworm and enable a historically large new Ebola outbreak, so it's not like they didn't achieve *anything*

Our highest and most urgent national priority should be AI safeguards. The risks of AI weapons, pathogens, mass unemployment, surveillance, and even extinction must not continue to be largely ignored.

Schedule F Has Arrived -- a modified version of the long-feared ‘Schedule F’ has arrived albeit in a somewhat truncated form. Thousands of career civil service positions are now political positions subject to new rules including greatly enhanced ease of quick dismissal. Curiously there has been no public mention of this dramatic personnel overhaul by @NASA. Details: nasawatch.com/personnel-news… #NASA

We’re excited for Falcon Heavy to launch the Nancy Grace Roman Space Telescope as early as this August from pad 39A in Florida

“What’s this?” “Your next-generation space telescope, sir” “No, no no, it’s not 2027 yet” “It’s launching this summer now. We even did it under budget”

WE NEED SIGNAL PREEMPTION!!! @LADOTofficial
