NASA’s Jet Propulsion Laboratory laid off 11% of its staff today, including many people working on an active Mars rover mission. “There’s no whitewashing the ‘doomsday-eve’ feeling that's looming over all our heads,” wrote one JPL’er. eos.org/research-and...

The search for life's building blocks on Enceladus just got more complicated. Experiments show that radiation can also produce organics from ingredients found on the icy moon. 🔭 🧪 eos.org/articles/spa...

Space Radiation Can Produce Some Organic Molecules Detected on Icy Moons - Eos

As missions prepare to visit ocean worlds like Enceladus and Europa, new findings show scientists must first learn to distinguish between radiation-made organics and those born in a subsurface sea.

NASA's Jet Propulsion Laboratory to lay off about 550 workers

NASA's Jet Propulsion Laboratory said on Monday it will cut nearly 550 jobs as part of a restructuring, not related to the current U.S. government shutdown.

Oh, no argument there. I’m just surprised they broke the NASA party line.

Watching Starship test, and they just mentioned Starship will start lunar landings in 2028. Is that just a casual statement about (an unsurprising) Artemis III slip?

Oh, and it could do climate science, too!

Think of it like GRACE + GRAIL.

This paper was led by Mike Sori, and builds off of a Caltech KISS workshop we led a few years ago.

Gravity is a powerful tool and a dedicated gravity science mission might tell us how one of Mars’s oldest/biggest geologic features—the hemispheric dichotomy—formed.

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

For the love of fuck, literally nobody thinks that 20% of the population is transgender. Please stop sharing that ridiculous YouGov statistic

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.
