This series of documentaries was done incredibly well. The episode featuring the Hubble telescope is spectacular. It captures the technological challenges, innovations, and perhaps more importantly, the incredible human ability to adapt and persevere when faced with the impossible.

33:03 It wasn't a bad joint design. It was a joint design with a known limitation of inoperability in cold temperatures. NASA managers and D.C. politicians were warned against launching in conditions that were outside acceptable parameters. They ignored the warnings, and seven people died.

Yeah, how the documentary tells it is total BS. Actually makes me angry how they sugar coat it....or rather blatantly lie about it. They knew what caused it right away because they were warned about launching in low temperatures....well not everybody did, but the higher ups in NASA who green lit the launch certainly did. Thats what you get when politics override safety protocols.

Well said, Pete. Al MacDonald said Nasa wanted to launch outside of qualified parameters and wanted M-T to agree to that, hence the disconnect. I initially thought the o-rings were installed in a design that was impossible to solve i.e. to maintain seal in a dynamic gap, not a static one. But I came to understand the joint rotation wasn’t fully understood until much later.

Damn straight. As a EE I can guarantee don't listen/overrule your engineers at your own risk. Sometimes you have to remind people there's a reason engineers have above to well above average IQ's. Also why engineering school is the hardest to get into. But we engineers have been through this with the "geniuses" in management. Invariably to the assclowns detriment. Fortunately nothing like life or death for me so we got to openly smile and denigrate the turd burglar. 😎

The only comparison between Apollo and the shuttle is that they both went to and came back from space. They are completely different vehicles and really shouldn't be put in the same category.

Thanks for such an informative story. It's incredible how much effort and detail goes into find that small error like the O rings. I was also thinking, could the shuttle be checked by the astronauts while in orbit but I guess they didn't know about the damaged on the wings leading edge. And how many spare parts can they carry 😏. God bless them all

@johnhonda93 11 ай бұрын

It was definitely possible to do space walks to check for damage but they didnt. And they actually developed a paste that they could use to replace tiles in orbit. They just never used it. IDK if it would have helped in this situation. But they also started having a second shuttle ready whenever they launched one so that they could rescue the astronauts if they needed to.

SpaceX is new rocket starship Will you similar tiles but due to its geometry 90% of them will be identical and they will be attached to stainless steel which has a much higher melting temperature. Aerospace is built on previous innovations and it takes all of the successful and not successful to take us into space permanently.

Yup in the video it says the engineers found the problem was the O-rings when in fact it was Feynman who in the official inquiry showed that there is no resilience in the O-ring when it is at a temperature of 32 degrees Fahrenheit, the temperature at the launch of the Challenger that day.

@djpalindrome 8 ай бұрын

The shuttle was a great engineering achievement in its day but was built around too many inherently unsafe compromises - strapping the orbiter on the side of a huge fuel tank; using unthrottleable solid rocket boosters, never considered safe for manned flight; using a fragile thermal protective system to protect a vulnerable aluminum airframe, rather than using stainless or titanium

Search for "Lubrication of Space Shuttle Main Engine Turbopump Bearings". There's your answer. Each turbopump is powered by the exhaust of its own small rocket engine, or "gas generator". And by small, it means that it's ONLY 94,000 horsepower (input to drive it). Each. So it would take 375 NASCAR Cup cars (750hp each) to drive just the 3 fuel pumps on a Space Shuttle. The liquid hydrogen it pumps is used to cool it.

@michaelallen2501 Жыл бұрын

I wish shows like this were more honest. "Investigations discover that engineers from multiple companies associated with the design and construction of the shuttle warned upper management and government officials it is unsafe to launch, but those people (goes on to list every single fucking name) refused to listen to the engineers and said to launch anyways. Now 7 lives are lost because of the choices made by unqualified management and government officials." A fucking o-ring didn't fail. Management failed. Like management always fucking does.

As hard as it's been for the U.S. Government to hand over money to NASA, NASA has never had to hold a sausage sizzle or a lamington drive for their funding, but Australian public schools and, presumably, U.S. public schools have to do that just to send kids on camp or to buy new books for their libraries. Let's make education a bigger priority or at least give equal funding to education snd space exploration, and not nuclear submarines or supporting groups that do not advance the human race.

The challenger investigation didn’t revealed that the o-ring on SRBs has become brittled in cold weather… The engineers that design the SRBs already knew about this before the launch and recommends NASA not to launch. They even refused to sign the approval papers to launch but NASA wouldn’t listen . It was not an engineering or technical problem… it was political and gross negligence problem. The same kind of issue came up again with Columbia in 2003… NASA didn’t learn a thing from Challenger accident.
