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?

Yes, your substrate is undoubtedly distinct. And perhaps that’s determinative. But you feel you know enough about what makes a mind to find this distinction gives you complete certainty that complex software cannot make a mind?

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 is fascinating to see Jacob Coxon attacked from the left “He’s making it up to boost share values” & the right “He’s making it up to force regulation”. Anyone who doubts AI could cause existential risks lacks imagination. Anyone who thinks they know the level of! risk is overconfident. So…(1/2) 🧪

(Nobody really thinks it’s likely returned samples could harm or destroy life, or spacecraft could harm an alien biosphere. But can’t say risk = 0, & consequences could be dire. So assume the worst, isolate samples, clean spacecraft, avoid contaminating possible habitats, often at great expense.)

This is a classic case where the precautionary principle should apply. In my field, with Planetary Protection, we observe international protocols and take extreme measures to guard against possible risks which are, objectively, much more improbable. It’s the sane and responsible approach. (2/2) 🧪

#Nepal needs $5bn to rebuild from the #floods. Oil giants Exxon, Chevron & Shell made $36.5bn profit in the past quarter alone. The #LossandDamage Fund can provide only up to $20 million in emergency support. Shared thoughts with @stuti.bsky.social on why this is a test for #climatejustice.

I’ve been getting about one of these per week for decades. Haven’t noticed a recent uptick. And yeah they’re almost all from men. I keep them in a file labeled “kook”. Can’t possibly read them all and sometimes I wonder if hiding in the kook file is some genuinely important insight. But I doubt it…

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.
