概要

On January 28, 1986, millions of people, including schoolchildren across America, watched as the Space Shuttle Challenger lifted off from Florida. Seventy-three seconds later, it broke apart in the sky, killing all seven crew members, among them teacher Christa McAuliffe. In this episode of Knowledge Central, we look at how a small rubber seal, a freezing morning, and a series of ignored warnings led to one of the darkest days in the history of spaceflight.

In this episode:

  • The mission, the crew, and why Christa McAuliffe’s flight was watched in classrooms nationwide
  • The O-ring: how one part of a rocket booster failed in unusually cold weather
  • The engineers who warned the launch wasn’t safe, and why they were overruled
  • The Rogers Commission investigation, and Richard Feynman’s famous ice-water demonstration
  • How Challenger changed NASA, and the lessons it still teaches about safety and decision-making
