"ESA plans to release imagery by next week. NASA will not be able to release any of its data, or even comment on it, until the U.S. federal government ends the shutdown."

Interstellar comet 3I/Atlas is flying past Mars today. Might get some cool views!

CNSA has released an image of Tianwen-2 in deep space using a robotic arm, giving us a proper look at the spacecraft and return capsule for delivering samples from near Earth asteroid 469219 Kamoʻoalewa. Tianwen-2 has been in space for 125 days, is 45 million km from Kamoʻoalewa.

Against my better instincts, I have written some notes on how human probability judgements work and what you should expect from surveys that ask people to guess what proportion of the population is transgender. I hope never to speak of this matter again

In the last 6 days, 9 asteroids passed inside the Moon’s orbit. Estimated sizes: ~1–38 m. All were discovered this month, a reminder that countless small, faint NEOs slip by unnoticed until they make a close pass.

This is disgusting and insulting to the entire astronaut corp and NASA as an institution. Attitudes like this are why Challenger happened. This regime doesn't value human life, only the illusion of progress. We're also not in a space race, and even if we were, that doesn't justify risking safety.

NBC News @nbcnews.com · Sep 6

It's full steam ahead for NASA, according to Sean Duffy, the agency's acting administrator. During an internal employee town hall, Duffy warned of "letting safety be the enemy of progress" when it comes to winning the space race, according to a recording obtained by NBC News.

A new image of interstellar Comet 3I/ATLAS yielded some serendipitous art.

The Gemini South telescope observed the comet through four color filters. While tracking its motion, the telescope split the light from surrounding (unmoving) stars into little rainbows. 🔭🧪

noirlab.edu/public/image...

Comet 3I/ATLAS streaks across a dense star field in this image captured by the Gemini Multi-Object Spectrograph (GMOS) on Gemini South at Cerro Pachón in Chile, one half of the International Gemini Observatory, partly funded by the U.S. National Science Foundation (NSF) and operated by NSF NOIRLab. This image is composed of exposures taken through four filters — red, green, blue and ultraviolet. As exposures are taken, the comet remains fixed in the center of the telescope’s field of view. However, the positions of the background stars change relative to the comet, causing them to appear as colorful streaks in the final image.

OK, we've let go of about 20% of the NASA workforce, the Administration seems to want to force this 24% NASA overall budget cut & 47% science budget cut down the agency's throat by any means necessary, the lander is still the long pole in the tent & we're going to the Moon in 2 years? Sure, Sean.

Andrew Jones @andrewjonesspace.bsky.social · Aug 28

Which country returns astronauts to the Moon first this century will be fascinating to watch. But so far only one side frames it as a “race.” China has cast its space ambitions in broader, long-term strategic terms.

I am heartbroken and enraged that our hospital systems are abandoning trans people. Truly, disgusted that they are bowing down to our fascist government. I know some places are fighting, and I'm grateful for those doctors.

For me, this echoes what happened with abortion around the country.

A fundamental issue in our society right now is that people are unable to distinguish the difference between being uncomfortable vs unsafe (perpetuated for years by media)
Are you among an unfamiliar group of people? Are you in a big city? Are you really unsafe or are you just feeling uncomfortable?

The Trump regime is systematically crippling & blinding US science wherever science can provide independent information to the US public which the fossil fuel lobby doesn’t like.
A kind of self-harm for which the US will pay dearly for decades to come. Destruction is fast, recovery slow & costly.

Juno is an AMAZING mission. The camera onboard was never supposed to last this long (the radiation around Big J should've zapped it a while back) but it just keeps on ticking. Killing this mission while it's still working and producing great science is a crime.

NEW: The White House wants to kill off Juno, NASA's mission to uncover Jupiter's secrets. Fortunately, its legacy is clear.

Juno's a scientist, but also an artist: it revealed Jupiter as a living van Gogh painting hanging in the sky.
