The ISS and all spacecraft that dock with it run at 1 atm. Which is nearly all currently flying spacecraft. (And probably Shenzhou does too, since it's basically a Soyuz.)

Well, the good actors misclassified as bad actors should be told, so they can fix it. The bad actors should be told nothing, because that only helps them become more effective bad actors. How you differentiate, I dunno. That's the prob

Not really, but battery cycles and powering things on and off constantly does take a toll.

There's a transcript of an early story conference for Raiders of the Lost Ark, between George Lucas, Steven Spielberg, and Larry Kasdan where they present and hammer out ideas for the movie. You can actually see what parts of the movie

In Roman (and even medieval and early modern) cities the poor and working class ate food prepared off site because they lacked kitchen facilities, specifically for cooking. If you lived in an insula (apartment) or such, you would take your

There's a definite difference between blame and cause, and they don't conflict. Blame is for individuals, cause is for systems. While you do need to hold individuals accountable, most of the time you should focus on fixing the sys

There's probably some of the former. Many fossilizing environments are more dangerous, and sometimes in surprising ways that more cautious--or experienced--individuals would avoid or approach more carefully. Tar pits, caves and crevass

Insurance and hospitals basically do bulk deals. Insurance is probably paying for the service one way or another, so they don't care much to whom the record is attached. And if you're not out of pocket, doesn't matter much to

It's a very programming-like phrase, actually. Just parse it from the inside out: (isn't (guaranteed to be (a failure)) An equivalent might be "has some chance of success" but that misses the sense that the presumption i

There's a variety of covert surveillance devices that have been remotely powered, but most of those were very early before you could get good batteries. I don't see a lot of reason for one today.

Efficacy (the main thrust of Phase 3 trials) could be sped up and made more thorough by deliberately exposing participants. I think one could argue that deliberate exposure and waiting around for enough people to be "naturally" ex

The structure apparently was inspected several years ago and declared sound. I suppose one can always say "more thorough inspections!" but it looks like this was a surprise and would have happened on any reasonable budget.

The mRNA must enter a cell to express proteins. The delivery vehicle is a "lipid nano-particle", a particle that can contain a payload and attracts surfactants to protect the payload but also allow it to penetrate cell walls. They

So one of the other problems with high power lasers is cooling the lasing mechanism. A recent novel solution to that is to have a liquid with the same refractive index and to circulate it (with no turbulence) through passages within the las

The chart is tons to LEO. Saturn V wasn't designed for LEO, but it certainly could have dropped that much there. (Skylab used a pretty fair fraction of that capability.) When you're comparing launchers you have to pick some baseli

There's tons that no longer exist as independent entities. Of the Big 5 movie studios, only MGM is still independent. 20th Century Fox is under Disney, Paramount is under CBS, and Warner Bros is under AT&T, though they retain some

That'll be changing quite soon, especially at high latitudes, with no action from local entities. See: Starlink, and maybe later other LEO constellations.

Did it work at scale, or did it work because it was employed early enough (along with other strict measures) that it didn't have to scale much? The latter is my understanding.

That's $13,333,333.33/oz, if you charge the whole cost to sample collection. They also get plenty of other science observations, but the main point was sample return. Apollo brought back 842lb of samples for something like $260 bi

Many of the fabrication techniques rely on sharp angle bends in the sheet, which would not be ideal in plastic.
