73.162 seconds after takeoff from Cape Canaveral, FL, on January 28, 1986, the Space Shuttle Challenger broke apart over the Atlantic Ocean. Disintegration of the vehicle began after the failure of an O-ring seal in the right solid rocket booster. All seven of its crew members perished:
- Francis R. Scobee, Commander
- Michael J. Smith, Pilot
- Donald McNair, Mission Specialist
- Ellison Onizuka, Mission Specialist
- Judith Resnik, Mission Specialist
- Gregory Jarvis, Payload Specialist
- Christa McAuliffe, Payload Specialist
After a lengthy investigation by the Rogers Commission, NASA’s organizational culture and decision-making processes were identified as key contributing factors to the accident. Flaws in the O-ring design were known at the time but had been improperly addressed and warnings about the risk of a low-temperature launch ignored. The disaster led to a 32-month hiatus of the Space Shuttle program.
