Doubt it. He seems to be a source of his own PR problems for the most part; I can definitely see how he can cause people to hate him, his personality seems smug and abrasive. It’s just I’m casting stones in a pressurized dome on Mars on this matter. Combine this with people who have a penchant for hating rich people (or even better) in general - until those rich people suddenly make a symbolic gesture in favour of their politics - and you have a pretty sizeable base of (pardon the juvenile term) haters with a disproportionate access to the media. I honestly don’t see the dreaded oil company conspiracy with armies of ULA snipers.

Amusingly, the two clouds are inside a low-density Local Bubble, so the LIC is below average Milky Way density.

Even though lighter than straightforward magnetic confinement, it’s a very bad idea from an engineering standpoint. So, instead of pulsing a magnet, the fusion fuel is fired quickly (10 km/s) through a constant field (not dissimilar to a rocket nozzle’s throat, actually) to achieve an identical result. This requires a pretty OP pellet gun, though; railguns and light gas guns aren’t up for the job, but laser ablative propulsion is, and it warms up the pellet as a bonus. Shamelessly stolen from @nyrath. Discuss.

Usually it’s for the community. Misery loves company, as does covetousness - and the desire to exterminate every person with a net worth of above 10 mil., which is something you see Reddit’s radical underbelly call for on a frequent basis. Plus, you can hook people up to the respective Discord and organize brigades against rival subs. But I’m sure they’d never do that.

Just go take a look at the Trotskyist hellhole that is by now r/EnoughMuskSpam.

Tell that to the Proton. The new parts need hammering out to fit; there reportedly was a big scandal when the issue was rectified and the two guys who’d been fixing that exact issue in every flight article for thirty years were laid off.

TVTropes have been radically pruning itself under new management, succumbing to all the ills of a Tumblrite fandom in the process. Enjoy the fork: https://allthetropes.org/w/index.php?title=Category:Did_Not_Do_the_Research&useformat=mobile

Hello darkness, my old friend...

Had to skim through quite a bit of articles on hacking to draw up a small dataset. Had ran across some useless but amusing ones. Sysadmin gets drunk and goes on to try to deface kremlin.ru, gets instant V-E Day amnesty Seventeen-year-old kid gets cocky and... tries to deface kremlin.ru, from his own home wi-fi, no less Guy gets convicted for messing with the navigation software of a freight airline; no difficulty finding him, he’s already in jail on the charge of getting his ex-wife to pick up a booby-trapped explosive package North Koreans are so rich, they try to smuggle $200k in cash from Vladivostok in shoeboxes... twice A search for SWIFT the interbank wire system ended up with me on Kaspersky’s blog, staring at an image of Taylor Swift with 2.3 Mb of Chinese botnet malware encoded into it The apex of it all, the antimalware program from North Korea! (may include free malware - unlike Ammazon Security Suite, which IS malware; Kaspersky’s retelling is more accessible)

Depending on how you view the Silicon Valley crowd? Some of it... or, actually, most of it goes to the Deep State. *dun-dun-DUN!*

A series of vacuum-brazed tubes are doing just fine in the 230 atm RD-170, although the throat region is machined instead. Glushko developed initial vacuum-brazing techniques back in the late 1940s, along with welding techniques that allowed leak-proof welds in the propellant injector manifolds, something US designers avoided for decades.

The Kola hole stopped when it hit 180 °C in the Baltic Shield, approximately a third of the way to the mantle. A different project in Bavaria hit 260 °C merely at 9 km.

Not really. This thing, made from rejected 23 mm AA gun barrels, mucked things up again. N.B. Russian firearm regs discount the existence of rifled shotguns entirely. This is a “carbine”, despite going past the arbitrary 20 mm limit.

Yes, but the esoteric techniques have been mastered to the point where even IRFNA and (I suspect) trifluoride/pentafluoride could be used fairly reliably. Ablatives remain rather unpredictable, however, and that’s probably inherent. Edit: it appears that Energomash fired an Isayev 4D75 staged combustion engine with pentafluoride instead of NTO as RD-503. Zis is not nuts, siz is super-nuts, but I’m not sure which propellant served as coolant.

Nope; ablative coating has fallen out of favour on smaller thrusters, replaced by various forms of pure radiative cooling. On larger engines, it’s supposed to be simpler (e.g. the “low-cost by design” RS-68 uses it), but it has enough wrinkles to make regenerative cooling simpler. Plus, as you may notice, regenerative cooling dates back to the 1930s, while ablatives would arrive from large solid-propellant missiles. Shouldn’t happen. NK’s teams were well-burned by random debris ingestion on the N-1, and RD-170 (171) had similar problems on the Zenit (but not on Energiya). There are pretty fine wire mesh filters on all intakes now.

The AJ-260 was segmentless, cast directly on-site instead. No O-rings. The Soviets delivered solid motors of similar size, if a decade or two later. However, I think you’ve hit something on the head: the Soviets would have likely hit the usual rail mobility bottleneck with an SRB program.

I’m more thinking about selling cigarettes and Bofors guns to either side.

Sweden.

Note the increased wall slope, and presense of landing legs, on Federatsya.

Probably. There’s simply much more energy involved, and that’s probably a source of risk that can never be entirely mitigated. Plus, the Tyrrany of the Rocket Equation punishes anyone seeking to include safety margins.

Well, not really, “what Maxime Faget wants, Maxime Faget gets”, so once crossrange requirements were established, the range of acceptable designs shrunk severely, mostly to what had come out of Marshall and Langley and was rubber-stamped by the private industry. This wasn’t gonna fly:

Because it used an entirely different kind of TPS?

Relevant to this thread. Minutes ago an FSB strike team dragged a, quote, “VERY drunk” passenger off an Aeroflot flight after he tried to reroute it to Afghanistan while brandishing... something vaguely pistol-shaped. Edit: video - https://www.rbc.ru/rbcfreenews/5c4720af9a79471b37b32db4 - and yes, the whole plane clapped, just like bad internet stories Do you see why booze doesn’t fly?

I don’t see any of the ancillary equipment on the site. Oh, and yes, the fuel tanks are stainless.
