Why did the Challenger explode Richard Feynman?
When this happened, the fuel tank released liquid hydrogen into the atmosphere where it exploded. As Feynman explained, because the O-rings cannot expand in 32 degree weather, the gas finds gaps in the joints, which led to the explosion of the booster and then the shuttle itself.
How did NASA fix the O ring problem?
During the Challenger liftoff, one of the main O-rings between sections of the rocket failed, allowing hot gas to escape and cause an explosion in which the crew perished. After the disaster, the joints were redesigned with an extra piece of metal inside to hold the sections together.
Who figured out why the Challenger exploded?
It was Sally Ride’s. Ride, a physicist and astronaut, was on that investigative commission too, and it was she who uncovered the suppressed data about the O-rings. As her fellow commission member, General Donald Kutyna, revealed to Popular Mechanics: One day Sally Ride and I were walking together.
What did Richard Feynman say about the O ring?
Feynman states that the O ring material has no resilience at 32F or 0C which was the temperature at launch. This allowed the O2 leak from the main booster tank.
What did Richard Feynman learn from the Challenger disaster?
He learned many things from these people that would help him to discover the cause of the explosion; and also information that helped him realize what a risky business flying a shuttle really is. NASA officials said that the chance of failure of the shuttle was about 1 in 100,000; Feynman found that this number was actually closer to 1 in 100.
Why was Richard Feynman on the Rogers Commission?
There isn’t a single magic solution, because these problems are subtle and often masquerade as normal. Richard Feynman (1918-1988) was a Nobel Prize winning physicist and one of the best-known scientists of his time. In 1986 he somewhat reluctantly agreed to join the Rogers Commission, whose task was to investigate the Challenger disaster.
How did Richard Feynman find out what happened to the shuttle?
Little did he know that he would be the one person to discover the exact cause of the explosion. Feynman was always the inquisitive type; he had to have the facts. To find out what happened to the shuttle, he went straight to the people who put the shuttle together.
