The Challenger disaster shows why scientists and engineers need an understanding of statistical techniques. The basic analyses described provide strong quantitative evidence that the shuttle should not have launched because of the significantly high probability of O-ring failure, a critical component of the spacecraft.
Challenger's fateful mission – flight number STS-51-L – was a unique mission. Among the crew there was Christa McAuliffe, the first civilian astronaut. ... The disintegration began with the failure of an O-ring seal in the right Solid Rocket Booster (SRB) that let a plume of hot gases break through. This plume, acting as a blowtorch ...
An Engineering Team Which Tackles Russian Roulette. It comes to the attention of a civic minded engineer that a group of teenagers in his community are planning a game of Russian Roulette in an abandoned warehouse. Alarmed, the engineer calls a group of his friends who mobilize an ad hoc task force to address the problem.

The night before the disaster— as engineers tried to convince their managers at Thiokol and NASA not to launch— someone pointed out that there had been signs of O-ring distress on a shuttle that was launched at 75 degrees. It's true— there had been issues at 75 degrees. And at 70 degrees. And at 63 degrees.

The O-ring failure on the Challenger can be broken into these two causes below. O-Ring Failure Breaks Into Two Causes. You may be aware that it was below freezing at Cape Canaveral, Florida the morning of Jan. 28, 1986, which made it the coldest launch in NASA's history. Because of the colder temperature, the O-ring material was less malleable.

The lowest temperature of any of the 23 prior launches (before the Challenger explosion) was 53° F [view source]. The "evidence" that the o-rings could fail below 53° was based on a simple conclusion that since the launch at 53° experienced two o-ring failures, it seemed unwise to launch below that temperature.

The failure of the putty to act like the La Brea Tar Pits around the O-rings to provide a thermal barrier (like the Fuller-O'Brien putty would have) and instead become hard like a board in the cold weather (which the Randolph barrier did on the Challenger), caused blow-by through a blow hole, eroding both of the O-rings, and causing a three ...

In 1986, the space shuttle Challenger exploded during take off, killing the seven astronauts aboard. The explosion was the result of an O-ring failure, a splitting of a ring of rubber that seals the parts of the ship together.

The Space Shuttle Challenger exploded 73 second after liftoff on January 28th, 1986. The disaster claimed the lives of all seven astronauts on board, including school teacher Christa McAuliffe. 1 The details surrounding this disaster were very involved.

Challenger Explosion On the morning of January 28th, 1986 at Cape Canaveral, NASA's space shuttle, Challenger, awaited take off.. Many watched the broadcasted event optimistically, while concerns were growing among the Thiokol (manufacturer) engineers of the spacecraft because of the significantly low temperatures before take-off, which may cause an …
On October 1, 1985 - about four months before the Challenger launch - Ebeling wrote a memo his Morton-Thiokol boss, Allan J. McDonald, that began with "HELP!" The engineer went on to express his concerns about task force delays and described them as a "red flag." From there, Morton-Thiokol reached out to NASA about ongoing O-ring problems and scheduling …

5. The o-rings were not rubber, they were silicone, which has much higher temperature resistance than rubber. There was not a single o-ring, there were two, so if one burned through the second one was supposed to hold. They were sealed upon assembly in the field with mineral paste and the joint between the two booster sections was secured with ...

Challenger was destroyed due to a faulty O-ring seal in one of its booster rockets, allowing burning gas to escape. The rubber O-rings, of which there were a primary and secondary between each rocket segment, weren't supposed to be burned by the gases resulting from liftoff, but that's exactly what happened during the testing phase.
