Mark Sykes describes just how much funding is being withheld from NASA's Planetary Research & Analysis programs: blog.planetary-research.org/2026/09/25/r... (With the context of how what Congress has ordered has already been well below what the National Academies recommended.)

Just came across this cool artifact: “Viking Lander Biological Instrument, Life on Mars” matchbox. (“The most complex instrument ever flown “) From a party in Pasadena for first Mars landing in 1976. Handed down to me by the late, great Shirley Arden (Carl Sagan’s long time executive assistant). 🧪
Picture of a gold matchbox with black design of a little Martian bug holding a spear and sword, with the lettering: VLBI, the most complex instrument ever flown.Other side of the matchbook .The little Martian dude with “TRW” and “Life on Mars?”

Wtaf is this question my university just asked me about my project?
Does the project involve any work that could be interpreted as promoting DEIA, climate change research, or non-compliant to any Presidential Executive Orders?

How do you know? Do you know what makes a mind? Or how it works? Or what happens when we create a sufficiently complex machine that recognizes patterns, connects information and iterates in novel ways? If so, you are the only person on Earth who does.

It’s odd, and a little disappointing, that @barbmcquade.bsky.social (whom I admire greatly) would assume that everyone is reporting differently from her on this because we must just “believe what we read on social media posts”, when we’re actually reporting on what we see directly on Google Maps.

NGC 6720 "Ring" - From Judy Schmidt (geckzilla.bsky.social) - flic.kr/p/gjBAcn
The Ring Nebula has a very nice set of data. It's very fun without a lot of odd things to deal with. I included the faint outer structures which resemble petals of a carnation but they are a bit underexposed and blurry. You can see them better here in an image which combines Hubble data with imagery taken from the ground.
