Feynman o-ring junta challenger

[aprilrosemusic]

Feynman is not a conventional or ordinary person.

This suggest he has tough life.

In most cases, you are accepted by your bull shit and not by what you know.

[Skeptic121]

If it had not been for Feynman, the cause of the disaster would have been covered up. Unfortunately for NASA, Feynman was smarter than they were. 

[givebirthathome]

Think about Fukushima. We don't know what all is going on...maybe ever, but HItachi apparently built at least one of their reactor cores, and Mitsuhiko Tanaka, an engineer, has come forward and said they kludged a solution after there was a flaw in the manufacture of the core containment vessel, and installed it anyway. He got a 3 million yen bonus. After Chernobyl, he reported it to the Japanese government, and then they covered it up.

Management is responsible...for everything. Managers are supposed to manage...that's their job. If a worker is doing something wrong, talking on his cellphone, texting someone...it's down to management to correct that and make rules and make sure their followed. Management at NASA, Marshall, and Morton Thiokal killed 7 people in the shuttle. It's their responsibility. The same is true for the Columbia disaster.

Thanks very much for the clip - do you have any more of the footage, or can you tell us where you got this vid from?

we had an unseasonable cold spell that winter in florida; i remember even ice flurries observed in N Miami Beach! i was thinking the day before that no shuttle had ever had an accident, what if...? the next day i was astounded by the loss of the ship and crew... a day which will live in infamy...

[mugwamp4]

2 things i find strange,, how cold it gets in Florida

considering its about 24"" north of eq and nasa has 9 fucking months of the year when its warm to launch the shuttle why do it in winter?????

[chodaboy51500]

1: It isn't uncommon for South Florida as well with much of the southern US to get freezing temperatures. It happens when the north polar jet stream dips to lower latitudes.

2: Because there is nothing wrong with launching in winter, but they should not have launched under freezing temperatures. Summer is more of a problem for launches because of tropical storms.

[ucihapokujin]

@chodaboy51500 i'm pretty sure their engineers were urging them to postpone the launch.

in the end it was more of the fact that the politicky side of nasa just wanted to get the damned thing off the ground because having their new kick ass, state of the art spacecraft grounded looked really bad.

on the plus side we learned that the shuttle program is a waste of money

[CaptainMacNasty]

@ucihapokujin - But, did the leadership of NASA learn it? I think not. In '93, working in Pasadena, I met a senior scientist with the Jet Propulsion Laboratory (JPL). His view of the shuttle was: "You don't need to build a Mercedes to carry garbage." Ultimately, the shuttle was far more complex and costly than the relatively simple tasks it was built to perform.

[LorysFan]

rather than about the actual weather it's about cooling

till this day space travel is still about rocket technology, and rocket fuel requires lots of liquid oxygene and god-knows-what-other-explosive­-stuff and this has to be kept at very low temperatures (you don't wan't your super explosive fuel to blast of simply cos it got too hot)

so wheather they do it in nevada desert in mid jully or in alaska mid january - the shuttle will have to be necesarily to bee cooled and thus coverd in ice

[schlusselmensch]

LorysFan, this problem involved the Solid Rocket Boosters, which do not use cryogenic fuels.

[DonMeaker]

@LorysFan The gaskets were between sections of the solid rocket boosters. Part of the problem is the cryogenic tanks are next to the solid rocket boosters, and so cool the SRBs and the gaskets.

[mannyortiz36]

while i was wrong on the direct cause my point about the windshear being related to the disaster is correct though?

[mrpossibilities]

One of those moments in human history.

[mitohistoriador]

Where's the damn sound?

[pacoberetta]

This scene is explained in the book: What do you care what other people think? by Richar P. Feynman.

[mannyortiz36]

little remembered also is that while, in deed, the seal malfunctioned during liftoff initially, it had resealed. about 30 seconds into flight challenger hit a wind sheer greater then any shuttle flight had previously (in the cabin crew casette transcript even commander scobee and pilot smith mention it) that caused the seal to fail again, this time for good

[avidalocan]

The 300 mile an hour windshear did not cause the seal to fail. Aluminium deposits in the fuel sealed the gap that the O-ring couldn't seal, and these were shaken loose by the hurricane-force windshear, also reported by a 757 Jumbo half an hour earlier that flew in the same area. That allowed the gas to escape. A windshear wouldn't stop a rubber seal from working, because it would just move with the ship. Aluminium deposits though would be dislodged in such an event.

[OscarLimaMike]

No sound or is it me?

[EGarrett01]

No sound.

[OscarLimaMike]

Thanks I thought I was momentarily deaf ;o)

[detlevi]

No sound here either.

[Sp3EdB4LL]

Questo è qualcuno che si può definire un genio!

Here is someone that you can call GENIUS.

[CondoSection17]

...and he took out the rubber o-rings, that he had put in icy water earlier, and smashed them to pieces! There we go folks; the reason for the Challenger Disaster uncovered by the genius that was R.P.Feynman.

[empath69]

And that wasn't the true source of the disaster; that was merely 'the bullet that entered the victim' - the gun was the mentality of NASA's management to "make the science fit the goal" and ignoring flaws to keep on schedule, etc.
