January 28, 2016 marks the 30th anniversary of the Challenger disaster, when a booster rocket failed 73 seconds after liftoff, triggering an explosion of the space shuttle’s fuel tank.


The space shuttle Challenger launched from the Kennedy Space Center on a mission to deploy a satellite in space. Six astronauts and schoolteacher Christa McAuliffe were killed. The failure of an O-ring seal in a solid rocket booster was later found to be responsible. Shuttle flights were grounded for two and half years after the accident, resuming with the launch of Discovery on September 29, 1988.
