There's also a very impressive sensor and actuator story.

That's probably venting of excess pressurants and/or an engine purge.

Yeah, that's a fishy claim. You could perhaps say it's technically true he currently holds title... until a court rules otherwise. Which is certainly would, unless Italy is doing something very unusual. I expect that's the st

It's a silly thing to say, because ship losses are largely driven by German submarines in the Atlantic and American submarines in the Pacific, which are about as disconnected as things get in WW2. You can see clear trends in the data i

Terminal has historical bindings to Ctrl-C and Ctrl-V that aren't copy/paste. (Ctrl-C is especially common, being "interrupt" or "quit".) Use Ctrl-Shift-C and Ctrl-Shift-V for copy/paste.

Though a large batch and large amount of flights by space standards, Shuttle was basically all prototypes by normal manufacturing standards. The 135 STS flights wouldn't even make a dent in an airliner certification and test campaign.

Debian doesn't depend on CrowdStrike. That's about people who installed it on such systems.

I'm very much on board with cuts and/or emendations to remove or update archaisms and obsolete cultural references, and align better to modern expectations with regards to length and intermissions and such. Unless your mission is

Whales and bison were subject to very modern techniques. While sailing whalers did stress whale populations, it was the steam launch and exploding harpoon that really did the whales in. Bison were destroyed with rifles, which are new in the

SLS uses improvements made late in the Shuttle program. Lower temp materials and some larger diameters. Presumably that exact problem is fixed. Others? Who knows.

Using a segmented solid was dumb from the start. Not to mention using a solid at all on a supposedly-reusable and/or human-carrying vehicle.

You must have some wild dreams. Starship and New Glenn are basically as dreamy as Ariane 6. Starship is essentially operational as an expendable launcher already, and NG is starting the paperwork for first launch. Ariane 6 will serve fine a

From about 1990 to about 2016 Arianespace was the leader in commercial (meaning mostly GEO) launch, and acted like it. (Actually, they still do, just it's less believable now.) In retrospect, I don't think they ever really had the

That's a very long time for anything to survive. Like, notably, their bones. But we do have evidence of some traditions from ~12kya, so it's possible some shadows of the idea are left. It can be thought that the folklore tradition

Dragon has capability for a Hubble servicing mission. It would need more development than a Shuttle visit, but it's not a huge hurdle since the last visit installed a soft-capture mechanism. (It'd probably cost less than an equiva

I really like how Vue lays things out; very clean and comprehensible. The official docs are pretty great, and there's generally one obvious forward path. But if you're doing anything weird there's a lot more out in the world

Despite their intention of debris lasting a minimal amount of time ("weeks") some of the generated debris lasted for several years. While this was much better than the particularly reckless Russian destruction of K1408, orbital co

Small generating turbines are almost always natural gas. For logistics purposes, the Antarctic program uses only aviation fuel, which is very diesel-ish, and for diesel piston engines are the rule. If you really wanted, I suppose, you could

An airless Earth would be extremely hard to land on. You could easily get to quite low altitude, but orbital velocity at sea level is almost 8km/2... faster than at "orbital altitude". Once you hit an orbit intersecting the g

Yes, but that's not the case for most objects you interact with in everyday life. All, most likely, unless you're in a particular job.

That'd take a human with taste a terrifyingly large 5 minutes, whereas AI trash can be entirely programmatic, with maybe an intern picking the best of 4 in a couple seconds. Think of the savings, and with only a moderate impact on the

"So does that mean that Autosteer actually makes crashes 59 percent more likely? Probably not. Those 5,714 vehicles represent only a small portion of Tesla's fleet, and there's no way to know if they're representative. A

Young terrestrial planets should tend towards a reducing atmosphere, due to all the rocks and such oxidizing. It took ages for life on Earth to produce sufficient oxygen to switch to an oxidizing atmosphere. We have evidence that Mars did s

There's situations where they make sense to rent and vice versa. Business traveler who just needs to go between the hotel and the airport? Great; may not even need to charge. If I'm flying into Vegas to do a roadtrip to the Mighty

The locks are all gravity powered. They certainly could operate the locks by pumping uphill instead of releasing downhill, and thus lose almost no water. I expect the expense of this makes it a non-starter.

I think the idea is that a foreign-owned major media company might be directed by that foreign government to work against national interests. Which idea is not so far-fetched.

You don't need to do any of that. You just hit the brake, which overrides acceleration. For this particular problem, drive-by-wire is superior to those mechanical controls.

The later structures are suggested to be funerary. The oldest one (with the lobes) is unknown. From the aerial photo, it seems they haven't dug the interior. They mention a gravel layer in the ditch which suggests a palisade. I'm

Perhaps a fort with a couple of additions.
