On January 28, 1986, the Space Shuttle Challenger disintegrated over the Atlantic Ocean just 73 seconds after launching from Kennedy Space Center in Florida. The disaster was caused by the failure of two O-ring seals in the right solid rocket booster. Record-breaking cold temperatures on the launch pad had caused the rubber rings to become brittle and lose their elasticity. This allowed superheated gas to burn through the joint like a blowtorch, eventually causing the external fuel tank to colla

How Feynman Solved the Challenger Disaster This video is inspired by Richard Feynman's investigation of the Challenger disaster and follows his approach to finding truth. January 28th, 1986. Space Shuttle Challenger explodes 73 seconds after launch. Seven astronauts die live on television. NASA forms a commission to investigate. They want a quiet report. They want to move on. Then they add Richard Feynman to the commission. Big mistake. Feynman doesn't sit in meetings. He talks to engineers. He
