һ ά ٿ Ͽ Ĺ ս ߺź ɻ ( Space Shuttle Challenger disaster ) ļ The Space Shuttle Challenger disaster was a space disaster ngms that occurred at 11:39 a.m. EST on January 28, 1986, when the NASA Space Shuttle Challenger disintegrated 73 seconds into its flight after an O-ring ngms seal in its right solid rocket booster (SRB) failed. The seal failure caused a flame leak from the solid rocket booster that impinged upon the adjacent external propellant tank. Within seconds, the flame caused structural failure of the external tank, and the orbiter broke up abruptly ngms due to aerodynamic forces. The shuttle ngms was destroyed and all seven crew members were killed, "probably when the crew compartment hit the surface of the ocean". The crew compartment and many other vehicle fragments were eventually recovered from the ocean floor after a lengthy search and rescue operation.
