Article claims the other way... But yeah. Honestly I'm willing to bet they're in it for other stuff as well, it is an RF resonator after all. Could be a disguise for other stuff too.

CIA tested cat-bugging in the 60s. The other thing to Space Exploration that pushes *anything* forward is Intelligence™.

What's with the high-pitched rumble with the rear cam (one over the nozzle) XD Or maybe all SRBs sound like that...

You should always check dates on any publication (videos, articles, recordings) - original source (if reposted), edit dates (if any)... But yeah. The point I made in general still stands. Starliner has only flew once, competitor in one form or another has flew 24 times. A difference of almost a decade in starting time made for it. Problem however, this is the ULA Launch Thread. ULA is Boeing + Lockheed Martin, not just Boeing. EDIT : Let me remind you as well that some social media recommendations recommends not on newness, but rather on how likely are you to spread it around.

Nov 2019, to be fair XD I'd believe that you sometimes have to spend away all your unluckiness, then you'd have luck from that point on. Boeing did their tests waaay later than the current competitor being ahead of them (competitor was in some operational state since 2010)...

I can imagine they were limited by their weight however.

That's probably why it was abandoned XD They probably think that no way anyone's going to swallow the pill, even if they safed it enough by military standards (which can be pretty darn low given they're already committed to work in rather dangerous situations anyway). But yeah, I've seen Destin Sandlin's videos of submarine stuff, some of the weapons systems can only accept weapons of certain sizes so anything designed to be compatible with existing systems have a hard limit on dimension. Retrofitting some stuff can be some equally (if not more) hard work on the other hand... so unless it's really necessary I think they'll just introduce it later for new designs or something (I question you can't upgrade something and it be compatible with an older standard) using safer stuff. (well, "safe".)

Thanks ! Yeah, I directly witnessed the CZ-5 maiden launch, back when they still streamed on YouTube; it was on some... "on-topic" channel. I was wondering if they've since made a similar presence on Bilibili. Registering seems to ask for a phone number rather than an e-mail address but I'll look if I can just use an e-mail address instead, has had a similar thing when signing up with Yahoo! JP. EDIT : OK, seems like the hoops are taller XD probably wouldn't try for now, hope they don't raise it further off

I mean, that image has more fin radiators and stuff now which are normal. But an entirely tubular radiator, seems like not the best in terms of performance, you'd get a lot of heat gradient along the tube and stuff.

... bbut... why ? XD Cool stuff man. The site (buran.ru) seems cool as well, sadly it's entirely in russian (there's a purported english version but it's entirely different).

I think the problem would be with handling - they said that some of the stuff they use on ships/subs/airplanes can only be of certain sizes, and they wanted to meet a certain performance that only fluorides could provide. Maybe.

Astronomy is mostly just observing the nature as it goes - Edwin Hubble started off as a lawyer. However we've kinda run out of stuff to observe on it's own (plus it's getting real expensive) that most of the time people do wait for the theoretical guys to come up with something to seek out. EDIT : I should point out that Hubble's 'constant' only a "constant" for a given time. We've since proved through observation (and testing against models) that the expansion of the universe is indeed accelerating. it has been 5 years since I dabbled in anything mathematical in cosmology, I think I can't really do it anymore XD

Crap, just seen this. Are there any kind of like channels that are guaranteed to upload/stream launch videos there ? If there is I might maintain a presence there as well.

Wasn't there some observation that showed that stars on the galactic disc actually have some inclination, and that the Sun is currently about as far out-of-plane as it gets ? Would this imply the velocity vector is roughly in the galactic plane ? Though it'd be interesting if there's a way to measure it, maybe wrt the galactic "center" ? Though yeah the real shock would depend on the ISM flow as well, it's a relative thing rather than a position-dependent thing I suppose.

Have anyone tested what is it like though ? I mean, in earthquakes, the waves that we have to worry about, the ones that gives the most of the ground acceleration and most of the deflections, displacements and destructive power, are the S-waves (and surface waves) only; it's the reason earthquake early warning works by detecting P-waves, since they arrive a while before all the bad stuff. True that our rod would be barely confined at all, unlike tectonic plates, and it'd be of little importance... But if anyone want to (or have had) test it out in real, I'd be grateful.

There's no such thing as a fully rigid bar - look at any physical structure around you, they all have to give way (deformation) in order to transmit force or even displacement. The compression would travel at the speed of sound within the material (as sound is simply waves of compression - there is also shear wave in solids though). Even diamond is reported to only have a speed of sound of 12 km/s; this is barely above the orbital escape velocity from Earth from sea level, and definitely a microscopic amount compared to the speed of light. You'd have a better chance at getting there faster by beaming a laser, or even just fling a much shorter rod really fast. What does intrigue me, however, is the fact that P-waves and S-waves have different speed in any material; would this mean that, if you both push and bend the rod a bit, will it arrive as two different motions in sequence ? Or is it like earthquakes, where only the S-wave matters (P-waves causes little deflection after all)

Only thing I've heard was that they need to sleep in one of the hatch module instead... did say about air pressure getting lower a bit faster than usual but that's it. I do hope that it's a clear punch hole though. If it turns out to be like the connection sealant, or even worse, corrosion or fatigue... then we'd have to think reeeally fast. Even most buildings on Earth have to be refurbished somewhere halfway through their expected lifetime...

Holy. Would this be even more pretext for them to just abandon the whole thing ? God I hope they'd actually repair it...

HTV-9 departing ISS : Just for archiving.

Good to know it has been fixed - had this problem with version 1.7.0 on 1.10.0 but I knew lots of mods aren't updating before 1.10.1 came out. Thanks !

Although, given their heap unload picture, it might be just drilling muck. I mean it'd be better if I can see a bore log, but that's often not available to average joe out of nowhere.

I mean, ok groundwater seeping into your digging hole isn't that unusual, but I'd like to know what part of the digging site is it.

Are those water on the floor ?
