The mission ended in catastrophic failure with the destruction of Challenger, starting at 73 seconds after lift-off, and the death of all seven crew members. The Rogers Commission determined that the cause of the destruction was due to the failure of an O-ring seal on the starboard Solid Rocket Booster (SRB). This flight marked the first time a non-government civilian, schoolteacher Christa McAuliffe, had flown aboard the Space Shuttle."@en . "Commander"@en . "Second"@en . . . . . .
