the challenger
Tuesday, January 28, 1986 is a day that will live on forever in infamy. This was the day that the Challenger, a NASA space shuttle, tragically exploded. The explosion left many people asking themselves, "What went wrong," and "What made the Challenger blow-up?" NASA conducted a report to find out just that. They concluded that it was many factors, these factors being the failed O-rings, the cold weather, and the leaky joint.(McGowen,57)Surprisingly, many people don't know what exactly happened to the Challenger. Ironically there were several launch delays for the Challenger. NASA disregarded the delays and ordered the lift off anyway.(Oberg, 725) Seventy-eight seconds into the flight the Challenger tragically exploded. The accident occurred at 46,000 feet in the air. The Challenger was traveling at about twice the speed of sound. Technically, the Challenger did not exploded, it fell apart due to structural failures. The crew cabin broke lose from the entire shuttle and went flying through the air. The crew cabin hit the Atlantic ocean within three minutes. The seven-crew members that belonged to the space shuttle were killed on impact. (725)Because of the seriousness of what happened in the Challenger accident a special team wa
The solid rocket motor joint has design deficiencies and my not seal properly with combined variable conditions existing on 51-1. It was very cold, 36 F (2 C), at the Kennedy Space Center. " During the 37 days that the Challenger stood on the launch pad, it was exposed approximately 7 inches of rain. (88) Putty performance in the joint may not be as intended by the design. It was therefore necessary to modify the solid rocket motor joint design to preclude or eliminate the effects of all these factors and conditions acting singly or in combinations. Mating conditions there afforded the highest potential for undetected joint damage performance. "(Oberg, 726)One of the major factors of the explosion is believed to be the weather. The Data and "Design Analysis Task Force then came to these conclusions, which served as the basis for the Presidential Commission's final report on the cause of the accident (Grunwald, 88)1. (McGowen, 57) The putty may act as a seal during the ignition transient and may not allow motor pressure to seat the primary O-ring. (McGowen, 58) Tests indicate that humidity can delay timely actuation pressure to the O-rings. "(McGowen, 57) it also added: "The failure was due to a faulty design unacceptably sensitive to a number of factors. "Water had drained from STS-9 when the pins were removed and 1/2 inch of water was in the bottom of the clevis.
