Love this thread. I also wrote on my Substack this week about fearlessness, quoting @timothysnyder.bsky.social’s interview earlier this week on @allinwithchris.bsky.social open.substack.com/pub/asharang...

Listen to someone who has been through it under Putin.

These seems horrible. And deserves more attention (amidst videos of ICE assaults, etc.). www.kenklippenstein.com/p/trumps-nsp...

This is a bad idea. External review of regulations has to be a better way for flier safety. Certificate Boeing’s track record is untrustworthy.

I liked it better when we called these mini-moons. (This isn’t important in any way, but it’s the level of energy I have right now.)

Here's an interesting look into the Nobel Physics Prize nominating process up to the early 1970's. It's a reminder that it's never only been about the science. And that the human factors in science arise especially in recognition of work. 🧪 pubs.aip.org/physicstoday...

Ellison is doing a great job in convincing me to stop watching television.

Third World Cup in a row I will be boycotting, and this time it’s in my country. FIFA bleeds out all of the joy in soccer/football.

When the Trump administration talks about opening up federal land, they are talking about selling off, at a discount, land that belongs to all of us. We lose on the land value and the local citizens have to pay for the consequences of lost ecosystem, pollution, etc.. 😡 eos.org/research-and...

Sometimes it takes a fleet of spacecraft to do great science. Or at least two. Here both SPHEREx and JWST are observing 3I/Atlas, the interstellar comet. Both telescopes find a carbon dioxide dominated cometary coma, which is cool. #planetsci www.skyatnightmagazine.com/news/3i-atla...

At some point the other countries will figure out that we are doing so much damage to ourselves by being anti-science and anti-rule-of-law that we won't have real leverage over them. They will shrug and say "Meh, go ahead and tariff us. It's a tax on your people and we don't need you."

Yep. Wilhoit’s Law explains a lot about the current situation. Doctorow lays it all out here: pluralistic.net/2025/08/26/s...

Constituent: You need to take your head out of Trump’s ass.

It's so cool to see actually planetary system formation at work. When planets form, they sweep up the dust and debris around their orbit, forming gaps like the one seen here. Plus, you can see the planet!! #planetsci www.eso.org/public/image...

When will the Speaker of the House wake up to the fact that the OMB director has stolen the Speaker's power? www.washingtonpost.com/business/202... The Trump administration continues to steal Congress' Article 1 powers and Congressional Republicans continue to do nothing.

Even the spaceflight training for astronauts sounds like fun: www.flyingmag.com/nasa-artemis... Nice to see Colorado as part of the lunar simulation stuff.

This xkcd about the tar command used to be me. No more, since I actually know the tar command. Now, it's the command for creating conda environments that would leave me helpless against a ticking clock. xkcd.com/1168/

Maryame El Moutamid and colleagues have discovered a new moon orbiting Uranus. The JWST observations show a 10km moon orbiting 56,000km from Uranus's center. This moon adds to the complex puzzle that is the Uranian ring and moon system. #planetsci 🧪 science.nasa.gov/blogs/webb/2...

One of my #planetaryscience papers is in here (plus one I co-authored). Funny enough, my paper was published in Elsevier, who's not known for open publication. I wonder if Elsevier will be suing Meta. Academic publishing was already bad. This makes it worse.

If you are in Colorado, you don’t need an officiant. You and your partner can marry yourselves (basically sign some paperwork). Make the ceremony what you want it to be. (Sorry to steal your thunder @niais.bsky.social )

Jim Lovell, a Gemini and Apollo astronaut, has died. Many may only know him from Apollo 13, but he flew in other Apollo missions and in some Gemini missions. www.nasa.gov/news-release...

After seeing the executive order trying to politicize science, this thread is what I need to bring a few chuckles back into my day.

Companies with their resort fees, extra charges, AI pricing, etc. are just going to force me to stop traveling. Jokes on them. I have a large enough library of unread books to occupy me for the rest of my life. Literary travel for the win!

Amazing seeing these dust clouds trapped between the coast and the mountains. I hope the Peruvians living there are staying safe from the dust. MODIS images continue to amaze. 🧪 earthobservatory.nasa.gov/images/15463...

I would find the atmospheric dynamics of these plumes more fascinating if they weren't attached to such devastating fires. In Colorado we are dealing with smoke from much smaller fires. I have much sympathy for those dealing with the Canadian fires. 🧪 earthobservatory.nasa.gov/images/15464...

Just by reading the headline, I new this Dartmouth alum had been part of the Dartmouth Review without needing to read the article. "One of the good guys" 🙄🤦 dartmouthalumnimagazine.com/articles/top...

Keep sciencing. We are living through a time when looking at a rock and wondering how old it is qualifies as an act of resistance.

With regard to the new paper on a spacecraft rendezvous with the new interstellar comet (produced by that notorious "it's aliens!" group in Boston), I like @acollierastro.bsky.social's term for this type of paper: a homework problem paper. It was just a delta-v calculation and some speculation.

Not only does this affect every day American citizens, but thus will likely affect military preparedness. The "unplugging" of these satellites is short-sighted and willfully harmful.

“What are we doing?”🔥 😳🇺🇸 Full: www.instagram.com/reel/DMa31OX...

The White House Press Pool should go on strike and see how fast the Trump administration starts begging them to come back.

This news makes me sad. eos.org/research-and...

At first, this news from Congress looks great (Planetary Society article) . Then I read about the OMB's plan to just ignore Congress. So Congress' proposed budget doesn't remove any of the stress or risk to science. This looks unconstitutional to me, but IANAL. www.huffpost.com/entry/russ-v...

I am very excited about this. Something to look forward to in the otherwise depressing news. www.theguardian.com/film/2025/ju...

They really are trying to destroy how everything works, without any real justification as to why the destruction is worth it. Maybe it's good to explore a different managing organization for JPL, but I haven't see any discussion of how this would help. nasawatch.com/procurement/...

Today, *every* living prior leader of NASA's science directorate have released a joint letter condemning the proposed cuts to NASA science. These individuals every administration from Reagan to Biden, and all believe these cuts are insanely destructive: www.planetary.org/press-releas...

Just a reminder about what Trump and the GOP are doing to our weather forecasting capabilities. And it's worse than what this article describes. www.theguardian.com/us-news/2025...

Keith's note: the pace at which people are leaving #NASA is going up. People with 25 years like Edward Gonzales are bidding farewell. I have seen many notes from folks but his post on LinkedIn just stopped me in my tracks. Reposted here with his permission AdAstra More: nasawatch.com/personnel-ne...

Sometimes we take the lake away (Owens Lake) and sometimes we create the lake, like Lake Manicouagan, which is an impact crater that was filled up thanks to a hydroelectric dam. The crater was created by a 5 km asteroid ~200 million years ago. #planetsci 🧪 earthobservatory.nasa.gov/images/15449...

“He’s not there.” @lawrenceodonnell.msnbc.com features yet another stunning example of Trump’s mental decline ht: @mikesington.bsky.social

I have grown interested in the fate of lakes on other worlds, from crater lakes on Mars to ephemeral lakes on Titan. Fortunately I have a lot of Earth analogues available, like Owens Lake in California. Let's not dry up lakes on Titan, like we did here. 🧪 earthobservatory.nasa.gov/images/15448...

The accumulation of actions similar to these cuts in subscriptions makes it clear that this administration is just anti-science. www.nature.com/articles/d41...

There’s still a chance we can stop the “Big Beautiful Bill” from passing! Call the congressional switchboard (202) 224-3121 & enter your zip. Tell the staffer or answering machine “I want to urge my rep to vote NO on the BBB. I am against cuts to Medicare.” That’s literally it. SPREAD THE WORD!

The GOP just collectively voted to add $4 Trillion to the deficit.

@astrokatie.com is right, you should just click on this link to Rubin images. But maybe do it on a computer with a large screen because there’s a lot of amazing to take in. 🧪

Some good news for Earth data accessibility and availability: www.earthdata.nasa.gov/news/data-fr... 🧪

It's clearly time to rethink the push for 1000 of small satellites instead of the older model or less, but larger satellites (or even a newer model!). These rocket launches have consequences, as highlighted by this news article and many posts by @astrokiwi.bsky.social www.rnz.co.nz/news/nationa...
