I traditionally celebrate Yuri's Night by brandishing the angryfist at the cloud cover.

Moon landing denial is a delusion, not an actual argument with reason behind it. No evidence, up to and including flying one of them to the landing sites, will convince them they happened.

It translates to minutes. Dimorphos completes an orbit in 33 fewer minutes than it did before it got smacked.

No, 33 minutes is 1980 seconds, because the article is specifically referring to the orbital period.

I think they were expecting Dimorphos to be a lot less squishy than it turned out. Instead of hitting a rock, the spacecraft struck a rubble pile, and was able to penetrate enough to dump most of its energy into Dimorphos rather than just dumping it onto Dimorphos.

To head off the usual flood of identical comments that seem to come up every single time this mission's mentioned: no, there is no possibility, zero, none whatsoever, that Dimorphos will somehow fly out of its orbit and hit Earth (or any other planet). It ain't gonna happen, that's known for certain, stop reflex-fretting about it.

I wouldn't say "more trustworthy" as much as "less likely to be burned to the ground by equity firms and other next-quarter-only types."

Yeah, "IPO" and "company built around long-term plans" are mutually exclusive, especially nowadays.

Pretty much. It's a black hole into which VC dollars fall and no useful product will escape, at least with any of the startups claiming to be working on the problem. They're always talking about direct physical rendezvous with some gimmicky method of capturing one single piece of debris, which isn't ever going to so much as dent the problem.

It's laser brooms or nothing, and none of the startups are looking in that direction - again, because none of them have any real intention of following through anyway.

If redditors see a question mark in a post title they assume there can't possibly be a link involved, even by the usual standards of people being unwilling to go past a headline.

Every single post in this sub where the title's a question gets the same reaction.

Your images are consistently great but this one is just stunning.

All of those multibillion-dollar projects start with a handful of researchers poking at an idea for a few months.

The post isn't just a headline. There's an article attached.

"Noticably" doesn't mean a lot, on a human scale, when it's 21st-century scientific equipment doing the noticing.

You should probably read the article before posting comments like that.

Basically that, yeah. Debris recovery that involves physical rendezvous is a flashy dead end, but still a dead end.

With what delta-V?

Currently ten: seven on the ISS and three on Tiangong.

If that's the only thing you can think of I can only guess you aren't paying attention, given funds vanishing on those kinds of scales has been a thing for far longer than one new congresswoman has been doing the rent-free thing in peoples' heads. Unless you're saying she made those claims while Bush was in office too, I guess.

Spending the money doesn't count as losing it, but being unable to account for it definitely does. They didn't "just" lose that amount, but over the last decade or so at least that much defense money has just vanished into the aether without anyone being able to tell where it went.

To be fair that actually provided some kind of tangible benefit somewhere, which maintaining a couple hundred Liberty ships just in case the world suddenly needs a lot of 80-year-old cargo ships on short notice does not.

Yeah, it definitely beats all the posts in this sub where non-adblocked users get a separate (unrelated) video playing between every paragraph, if not every sentence.

Zero - it's not burning the right elements to be near that point yet.

Stars on the road to supernovas go through a sequence of burning increasingly heavy elements for increasingly short periods of time, and Betelgeuse is still in the helium-burning phase. The following phases burn carbon, neon, oxygen and silicon in order, and once a star starts gnawing on its helium that gives observers about one thousand years' warning. Betelgeuse is 600-ish lightyears out; if it was most of the way through that process we'd be able to tell.

That's actually been talked about quite a bit over the years. The general consensus is "schedule things based on the time zone you launched from, face towards the Earth's surface, and do your best to approximate the physical motions given you're in microgravity."

It's just a clickbait content-farm site.

Wouldn't be surprised if the posts were procedurally generated, since those sites do that more often these days since it's even easier than the traditional "steal other articles and throw a thesaurus at them" approach. We're going to see a pretty maddening amount of "news" "articles" in coming months that are just written by chatbots.

Pretty sure OP either owns or is working for that site, since they've posted nothing but links to it for months.
