What is the impact of the explosion of the space shuttle Challenger?

Take the Challenger accident as an example to explain the problems that will occur when the information is not clearly expressed.

Edward tufte, an information designer, once took the Challenger accident as an example to illustrate the problems that will occur when the information is not clearly expressed. He thinks that if Morton Theoco engineers can clearly express the data relationship between low temperature and SRB module burn-through, they may be able to successfully persuade NASA to cancel the launch of the space shuttle. Taft also believes that incomplete information expression may also affect NASA's decision on Columbia's last flight.

Challenger's accident is often a special case, such as engineering safety, cheaters' morality, communication and collective decision-making. In Canada and some other countries, this is a part that engineers must know before obtaining professional licenses. Roger Boysjoli, an engineer, warned that O-rings would fail at low temperatures. He quit his job at Morton Teoco and became a spokesman for workplace ethics.

Information about the space shuttle Challenger disaster;

1, the video playback point of the challenger's next launch shows that at T+0.678, a black-gray smoke is ejected near the connection part of the right SRB tail and the bracket of the outer cabin, and it stops at T+2.733.

2. The last visible moment of smoke is at T+3.375. It was later determined that the smoke was caused by the opening and closing of the tail seam of the right SRB component. The shell of the booster expands under the pressure generated by ignition. As a result of the expansion, the metal part of the shell collapses away from other parts, opening a crack and leaking gas with a temperature as high as 5000 degrees Fahrenheit (2760 degrees Celsius).

3. The main O-ring was designed to seal the cracks, but it failed to seal at the first time when the temperature was too low, and the auxiliary O-ring deviated from its original position because of the collapse of the metal part. In this way, there is no obstacle to the escape of gas, and both O-rings vaporize in the range of about 70 degrees.
