Space Shuttle Challenger Disaster ポスター

On January 28, 1986, a ruptured O-ring in the right solid rocket booster caused the Space Shuttle Challenger to explode soon after launch. This photograph shows the main engines and solid rocket booster exhaust plumes entwined around a ball of gas from the external tank. Because shuttle launches had become almost routine after fifty successful missions, those watching the shuttle launch in person and on television found the sight of the break up especially shocking and difficult to believe until NASA confirmed the accident. Many viewed the launch live due to the presence on the crew of Christa McAuliffe, the first member of the Teacher in Space Project. Media coverage of the accident was extensive: one study reported that 85 percent of Americans surveyed had heard the news within an hour of the accident. The Challenger disaster has been used as a case study in many discussions of engineering safety and workplace ethics and inspired the 1990 television movie, Challenger. Photo credit: NASA
