Making thrusters for moon landers
I bought a transit pass for Rome but I have only used it once. Turns out that traveling between all the ancient buildings is walkable, because of course they needed to be within walking distance when they were built.
@simonbp @wikkit sounds like a different high

"Schedule chicken" is a common aerospace industry term, where you have a schedule and two or more teams working toward it. Every team knows they aren't going to make the schedule, but none will say anything until eventually one is forced and can be blamed for the delay.

Common for the hardware and software team on a rocket to be playing schedule chicken. Or a big payload and a new launch vehicle.

It's named after the "game" of two people driving straight at each other until one chickens out.

Found a #cursed Lightning to "wired" headphone jack adapter that requires Bluetooth (to avoid paying Apple's MFI tax)

@wikkit It is wrong when people reduce system safety to just propellant toxicity.
If propellant is spilled out of the system, something has gone massively wrong to begin with.

Safety is multi-dimensional and needs to be evaluated holistically.

@wikkit strong bases and amines can be biologically challenging.
The False Morel has a monomethylhydrazine hydrate complex that can be decomposed into MMH. I'm not familiar with the specifics, but I don't think it would be an efficient process.

But NTO can be pulled out of the air, because it is condensed smog.

Whatever the word is, this happens with hydrazine a lot. People who know nothing about it are more likely to consider it impractical or unsafe.

It's amazing how spray foam can make anything look kinda cheap. This is one of the most expensive adapters in the history of humanity, made out of special alloys machined to better than the thickness of a hair, but once it's covered in spray foam it looks like it might as well be plywood.

NASA wants to dump the International Space Station into the ocean. Is that really the only choice? Can't we just move it to a higher orbit?

Nope. Here's why.

NASA wants to dump ISS into the ocean. Why not boost it to a higher orbit?

Because of orbital mechanics, that’s why.
