Hey just FYI I *think* the post to reply to for quantum physics isn't available anymore/has been deleted/is borked? From here: bossett.io/science-feed/. Just tried to reply to get on the science feed and got an error.

Now on @sciam.bsky.social: This year’s physics Nobel goes to 3 researchers who demonstrated quantum tunneling on a superconducting chip. By bringing this microscopic effect into the macroscale world, they laid important foundations for quantum computing.

Now on @sciam.bsky.social: A fresh look at old Cassini data shows surprising chemical complexity brewing within Enceladus. This time we've found oodles of chonky organic molecules that could be precursors to (or byproducts of) even chonkier biomolecules.

In my latest piece for The Planetary Report, I argue that we’ve largely lost the rhetorical ability to defend the unquantifiable values of space exploration—beauty, curiosity, discovery—in the face of an unrelenting focus on utilitarian pragmatism.

For Artemis III before taikonauts make moonfall, yeah, Starship’s the bigger concern there.

But more broadly problematic is this: the US has spent big $$$ supporting/building hardware for lunar return (Obama era counts, IMO) for decades on end—only to be here, reliant on a wild Hail Mary via SpaceX

Lee Billings @leebillings.bsky.social · 18d

Possible, sure.

But is it more possible than, say, any alternative from “legacy” US aerospace firms eventually being an order of magnitude pricier than that?

Lee Billings @leebillings.bsky.social · 18d

Not trying to excuse or defend SpaceX; just noting how remarkably gently the NYT piece treats these other very problematic parts of the Artemis program.

Lee Billings @leebillings.bsky.social · 18d

Lol’d at the NYT piece’s framing of SpaceX’s lunar lander as “riskiest”—something which is certainly true for Artemis III.

But meanwhile SLS and Orion are what make Artemis I-IV launches cost >$4 billion *apiece*.

That’s unsustainable—*riskily* so—and is why NASA went to SpaceX in the 1st place.

Dan Vergano @danvergano.bsky.social · 20d

Some interesting sociology of space news to watch with the NYT dropping a fairly thin, but obvious piece by one of their anointed today www.nytimes.com/2025/09/20/u... saying the obvious: NASA's SpaceX lunar landing plans are unlikely to work anytime soon despite a lot of U.S. chest beating. 1/n

I have a couple of comments about the "free speech hero" narrative about Charlie Kirk.

First, was Charlie Kirk really notable for supporting the free speech of people he disagreed with? I haven't noticed that, though I could have missed it.

So what I glean about this Mars announcement is that chemicals were found on Mars that on Earth are due to life, and no one knows any other way to make them on Mars. However, this is very far from knowing they *were* made by life. Reminds me of phosphine on Venus; "we don't know" doesn't mean life.

To sum up: we have

🪨 A cool rock from #Mars that may or may not hold evidence of ancient life

🛰️ An internal fight over whether NASA should spend its money on science or human exploration, and on what planet

🤔 A totally uncertain future for this amazing rock

Fundamentally the #Mars announcement NASA is making today boils down to: there could have been some chemical reactions in these ancient rocks that could have been mediated by living organisms. The word "could" is doing a LOT of heavy lifting there. 🧪
