The disaster resulted in a 32-month hiatus in the shuttle program and the formation of the Rogers Commission, a special commission appointed by United States President Ronald Reagan to investigate the accident. However the shuttle had no escape system and the astronauts did not survive the impact of the crew compartment with the ocean surface. Although the exact timing of the death of the crew is unknown, several crew members are known to have survived the initial breakup of the spacecraft. The crew compartment and many other vehicle fragments were eventually recovered from the ocean floor after a lengthy search and recovery operation. Aerodynamic forces promptly broke up the orbiter. This led to the separation of the right-hand SRB's aft attachment and the structural failure of the external tank. The O-ring failure caused a breach in the SRB joint it sealed, allowing pressurized hot gas from within the solid rocket motor to reach the outside and impinge upon the adjacent SRB attachment hardware and external fuel tank. EST (16:39 UTC).ĭisintegration of the entire vehicle began after an O-ring seal in its right solid rocket booster (SRB) failed at liftoff. The spacecraft disintegrated over the Atlantic Ocean, off the coast of central Florida, United States at 11:39 a.m. The Space Shuttle Challenger disaster occurred on January 28, 1986, when Space Shuttle Challenger broke apart 73 seconds into its flight, leading to the deaths of its seven crew members. Space Shuttle Challenger's smoke plume after in-flight breakup that killed all seven STS-51-L crew members.
