Some assembly was necessary for these Solid Rocket Boosters at the launch site and O-rings (as shown in Fig. Here, the black smoke is spurting from the rocket booster in front due to the gas leak from the arrowed area, and the picture at the bottom shows white smoke coming out.įeynman, a member of the Presidential Commission headed by William Rogers, discovered the main cause of the explosion as follows:ġ) There were two solid Rocket Boosters on this shuttle for shooting the shuttle into orbit. ![]() The above shows pictures of the Orbiter attached facing down. 1 (Photo 1, arrowed) immediately after the launch, and exploded soon after. On January 28, 1986, the space shuttle Challenger developed flame on the side of the Solid Rocket Booster shown in Fig. The causes were loss of elasticity in an o-ring due to low temperature and fuel leak due to faulty design.Īs people all over the world watched on TV, the space shuttle Challenger of United States NASA (National Aeronautics and Space Administration) exploded shortly after the launch, and took lives of all 7 members of the crews. 1) exploded immediately after launch, and took lives of all 7 members of the crew. "That's why they've lasted.Explosion of the Space Shuttle ChallengerĪs people all over the world watched on TV, NASA's space shuttle Challenger (Fig. They're actually lessons learned," said June Scobee Rodgers, the widow of Challenger commander Dick Scobee Rodgers, an educator who lives in Chattanooga, Tennessee. Today, there are more than 40 Challenger Learning Centers focusing on science, technology, engineering and math, mostly in the U.S., but including one in Canada. ![]() Investigators cited safety shortfalls and pilot inadequate training as key factors behind the accident.įamilies of the Challenger astronauts established the Challenger Center for Space Science Education just three months after the shuttle disintegrated in the Florida sky. So far, the only fatality in the emerging industry occurred in October 2014 when a pilot died testing an experimental passenger spaceship for Virgin Galactic, founded by British billionaire Richard Branson. "I just hope that the new entrants into the market learn from the mistakes of the past," Leinbach said. For example, the night before launch, engineers warned that freezing temperatures might be a problem for the shuttle booster rockets, but their concerns were quashed. The Challenger accident also exposed NASA management problems. SpaceX tests astronaut escape system for Dragon space taxi.These will launch on top of rockets, not alongside them, and have separate systems to fly crews to safety if a booster falters. It's an evolution." Six astronauts and a high school teacher flying aboard Challenger had no chance of escaping due to a spacecraft design decision, which is not being repeated on the passenger spaceships now under development. "Spaceflight is like any other big engineering system," he said, noting that cruise ships and aircraft became safer after accidents. ![]() Accidents remain inevitable as the field matures, said Mike Leinbach, a former NASA shuttle launch director. The policy shift laid the groundwork for today's commercial space transportation industry, which generated global revenues of $5.9 billion US in 2014, according to a report last year by the Satellite Industry Association. At the time, NASA's four-ship shuttle fleet, flying several times a month, was the nation's sole space transportation system.Īfter the accident, then-president Ronald Reagan banned commercial satellites from the shuttles and bolstered military efforts to develop alternative launchers. (NASA/Reuters) Accident investigators also found that pressure to maintain a busy flight schedule contributed to Challenger's demise. The NASA lost seven of its own on the morning of January 28, 1986, when a booster engine failed, causing the Shuttle Challenger to break apart just 73 seconds after launch.
