Journalist challenge: Use “Machine Learning” when you mean machine learning and “LLM” when you mean LLM. Ditch “AI” as a catch-all term, it’s not useful for readers and it helps companies trying to confuse the public by obscuring the roles played by different technologies. 🧪

Congrats to HiRISE and MRO for doing it again!
This is an OUTRAGEOUS image because it involves taking a spacecraft designed to roll 20˚ side-to-side but mostly point down, and having it pop a wheelie to point the camera away from the planet... (🧵) #PlanetSci 🧪

For anyone wondering why the HiRISE image of 3I/ATLAS only had an exposure time of a few seconds:
HiRISE uses a pushbroom imager with fast readout to avoid blurring images of Mars. To make this image, MRO had to be rolled around in a very unusual sequence.

Here’s an annotated version of our comet image.
We also want to thank our downlink and uplink teams who spent a huge amount of time working on this. Our camera was not designed to image interstellar objects 19 million miles away, but their hard work and planning paid off.

Three #NASAWebb discoveries in ONE! Webb shows there are FOUR dust shells (only one was previously seen), allowing researchers to narrow the stars’ orbit of one another to a LONG 190 years. Plus, they confirmed a third star is part of the “party”: https://bit.ly/4n1tpas 🔭 🧪

We need a reimagined LPSC flavored meeting and the locale should be Tucson in March, after the gem show. Plenty of hotel choices along the free tram line that goes to the convention center. Visit Tucson is onboard to support this. If anyone has the bandwidth to invent the meeting we've got the city.
Abstracts submitted to LPSC 2026 are required to comply with White House (non-legally binding) executive orders forbidding mention of topics related to diversity, equity, and inclusion.
At least USRA/LPI isn't hiding it.
But is this what our community wants? Or deserves? I don't think so.

3I/ATLAS has only done comety things for 140 days. I predict it’ll look like a comet on day 141. For 140 days this grifter has manufactured doubt. He’ll do the same tomorrow. He’s never going to stop. He’s the Terminator, if the Terminator’s job was misconstruing ice and rocks in space to be aliens.
