The Challenger Launch

The Space Shuttle Challenger will be launched by the National Aeronautics and Space Administration (NASA) tomorrow. Among several civilians, school teacher Krista McAuliffe was chosen by NASA as a space program, and she was a part of the crew. She was very excited about space travel and introduced the Crew, Commander Richard Scobie, Pilot Michael Smith, Laser Physicist Ronald McNair, Mission Specialist Ellison Onizuka, NASA Astronaut Judith Reznick and Payload Specialist Gregory Jarvis .

I will take an astronaut as an example. Some moments will leave a mark that will not disappear in our hearts. I remember the Space Shuttle Challenger launched in 1986, the excitement and anticipation before the launch, and the pessimistic suspicion and explosion of 73 seconds in flight. The loss of young teacher Christa McAuliffe is very personal. "Sometimes we will fail when we reach the stars, but even if the pain persists, we have to go back to our feet," Reagan said in the aftermath This sentence has had a big impact on my life. There are other courses. The committee to investigate the disaster concluded, "For the success of technology, reality must be given priority over public relations." This is one of my principles in my career.

January 28, 1986, NASA planned to launch the Challenger Space Shuttle from the Kennedy Space Center in Cape Canaveral, Florida. The launch was postponed several times. This work attracted a lot of public interest, mainly because the staff included civilians, a teacher of New Hampshire State as Krista McAuliffe. On the eve of the launch, NASA held a long telephone conference with engineers at Morton Thiokol, a contractor who manufactured the Challenger's solid rocket motor. Among them is the old man Allan McDonald of the launch site of Morton Thiokol. Florida is unusually cold - it is expected to be 18 degrees celsius overnight - so McDonald's and other Morton Thiokol engineers recommend to postpone the release again. They explained that the cold weather could damage rubber O-rings and prevent hot gases from escaping the shuttle booster. These boosters have never been tested at less than 53 degrees, and morning forecasts require a much lower temperature than this value.

Bill Moyer: Morton Thio Cole has his own pressure. The company is the only booster rocket supplier, NASA is its biggest customer. But one week before Challenger was announced, NASA announced that he was looking for a second source and asked four companies to participate in the bidding for this project. ROGER BOISJOLY: Worth over $ 1 billion. Now, the importance is not only currency, but they are the only source, they are the only company without competition. And being unable to accept key customers like NASA may endanger this situation.
