Raychem, founded in 1957, went defunct in 1999. They also developed and sold heat shrink tubing. And I do remember these toys from when I was a kid. Even then they'd be sticky and stubborn.

Actually, if a contractor doesn't perform on schedule, there are penalties involved. As for number of contractors, look at how many were involved in Apollo and the shuttle. It's a bit of a miracle we only had one Apollo 13 mishap, given changing specifications and voltages. I'd still go for one suit to rule them all, with protective overgarment to be installed before use for specific environments. Less mass to be lugging around and the overgarment isn't something with much in the line of active components being needed. After all, every suit since Apollo was an under suit and the overgarment for micrometeor protection, insulation, tear protection, etc.

Only in small part. There is also cardiovascular effects to consider, things like standing up and the circulatory system pumping harder to overcome gravity to pump blood up to the brain and up from the legs. You're also not loading long bones, so degradation would continue. Simpler, put the entire hab in the G zone and have remote hub or outside of the rotating system microgravity labs, the remainder stays in the hab zone.

That stage is obviously no good. All of the other ones were good, that one isn't. So, upon return, SpaceX will replace that stage free of charge so that SpaceX can re-run their mission with working equipment. Largely, to avoid a collision risk. Seriously though, I'm with Scott, there's liquid also leaking, which suggests it's a LOX leak, likely from a ruptured line or connection. Shake and rattle you (along with vibration) that much, you'd fare far worse. I'll always fare better though, as I actively avoid the propulsion stack when it's in use. Dad may have raised a dummy, but he didn't raise no fool! I'll see myself to the door...

@msudawg1997 that is one failure to the high speed imaging technologies that most of the public is not aware of. Still, I suspect that at 300 fps, usable data will be acquired. Keep up the excellent work! Tests like these save lives and equipment!

@nemo-x and tellingly, is putting most stuff into space. What have you put anywhere, beyond a Twinkie into your mouth?

@msudawg1997 BTW, I used to work with 15000 psi test hydro-pneumatic systems, what was the failure pressure of that monster tank?

Chet Carson no, man never walked on the moon. Shuffled, hopped, jumped, fell a hell of a lot, to the point where the team that built the spacesuits were near having massive coronaries. Walked, not at all. Walking just ain't in the cards for creatures evolved under 1G, trying to move around under 1/6th G. I've even said as much to Buzz Aldrin, which was greeted with a snort and nod. To which I gave a scout salute, as a full hand salute would've been inappropriate, neither of us being in uniform.

@roach1371b actually, Scott, that would be an excellent topic. Both from phosphene possibilities to direct stimulation of the retina and phosphorescence of the vitreous humor, as well as the effects of bremsstrahlung radiation.

@PureAmericanPatriot "absurd obsession with safety", meaning, allow deaths and destruction of expensive equipment and losing funding is a goal. I'll happily hop onto any rocket NASA launches, at least it won't have holes drilled through the skin of the space capsule.

@msudawg1997 5psi? That's insanely low, considering flight considerations. Try to send me on a tank with that low pressure, hear my response! 15 psi, we'll talk. From start to finish, otherwise, that's insanely low.

@msudawg1997 cumulative stress over a large area makes for massive forces! Reminds me of an air start bottle, high pressure reservoir, low pressure output, connector ill seated meant a six inch hose endangered everyone on the ramp.

@PureAmericanPatriot actually, I understand quite well. Not entirely certain though, as to which comment you were replying to. Remember though, tolerances are for loading, shear, vibration, etc and can be cumulative, so typically there is some degree of excess to avoid unforeseen conditions, such as an engine thrusting out of spec in a multi-engine stage, in particular, the sudden change in load dynamics with an engine cutoff that was unanticipated.

Chet Carson yeah, OK, genius. 10000 people worked on the program, not a one blabbed. The spacecraft have been imaged by a current lunar orbiter, but they're not there because the moon is made of cream cheese or something.
1
Chet Carson as I said, 10000 people all kept quiet, even Russia, our enemy, went along with it. Keep on sailing in loony land, sugarbumps. There's a room with rubber wallpaper with your name on it waiting.

Chet Carson "Sorry chuckles, you can try to spin it all you want but man never walked, hopped, skipped, crawled, stepped, or even fell on the moon." Your words, not mine, they're plainly in the thread. Troll elsewhere, you're blocked.

@w0ttheh3ll totally true, as true as the random seek time is superior in tapes to that of SSDs. And up and down being exactly the same direction.

@TheSentientCloud as I recall, implementation of RFC2549 did suffer from some drawbacks and major flaws. Data fragmentation, where datagrams did arrive out of sequence and late quite often. There was also a problem with encapsulation in hawks, in which de-encapsulation created a messy, lossy result with massively mangled data. There was also the potential, which has already happened once, of extinction of the data without a suggestion of transmission (see passenger pigeon). Worse was replication experiments suffered from interference due to my affinity for squab.

Are you sure that there wasn't a lunch order in the Italian one? Or perhaps, a shopping list. Yeah, anything official from Italy can occasionally get downright zany and that's coming from an Italian-American. Although, many Italians might beg to differ, something they dislike about Sicily...

They can try the new warranty return program. Return the defective rocket for replacement. Yeah, it's gonna return fairly quickly, it is LEO. But, in fairness, it proves that that particular stage is rubbish. The rest were OK, that one's rubbish and it looks like a LOX leak, so likely a bum pipe.

@sergeant_salty why, thank you for not caring about $8.00 out of ever $100 of your paycheck! Being on fixed income, I appreciate the donation!

@charleshill9778 that's a different percentage than originally quoted, so how about some actual numbers and citations? That asked, NASA has always, from day one, given contracts to contractors and gasp! paid them. That was quite well established back after Apollo 1 burned with the flash in the pan with the Phillips Report on one vendor underperforming. As the hearings at the time were on the Apollo 1 accident and that report was beyond irrelevant, it went nowhere. Oddly though, that vendor eventually was not the one making the CM and SM when we got to the moon, Grumman made the LEM, North American Rockwell made the CM and SM. With Grumman jokingly sending Rockwell a towing bill for Apollo 13 and Rockwell replying how they towed Grumman's LEM repeatedly to and from the moon... ;) NASA designed some things, contractors built and completed designs or even used their own designs throughout the programs. As they well should, each to their level of competency. The space shuttle being Boeing and Lockheed made, not NASA built. SpaceX blew apart their own launch pad. NASA only blew up Wallops Island a few times. :P

Well, a pure electric engine is possible. It'd have a bit less thrust, say around 1/80000th the thrust of an argon engine, but one could be made. It'd also be known of as an immense waste of energy, effort and equipment, as the heat from the damned thing would provide more thrust and still be far, far, far less than say that argon engine. As in, the Pioneer anomaly was detected after a decade... Solar sails would be more efficient and far faster, which still isn't saying much. Still, there is the EM drive, powered by its free lunch system that ignores the laws of thermodynamics. And after all, who, other than Mother Nature can refuse a free lunch? On just needs to get an Alder Wand...

@carlwest859 I think you mean helmet suspensions, helmet liners go all the way back to WW2. Modern helmet suspensions did largely come out of NASA, as they considered a really good idea to not scramble the brains of astronauts by their colliding with the inside of their helmets. One shuttle casualty added to that knowledge tremendously, with subsequent helmets suspensions greatly enhanced as a direct result of findings from the cabin falling and tumbling.
