Challenger Disaster: Key Events and Lessons

The video covers the tragic Challenger disaster of January 28, 1986, where the space shuttle exploded shortly after launch, killing all seven crew members. It details NASA's space shuttle program, Challenger's achievements, and the STS-51L mission. The investigation led by Richard Feynman revealed that a faulty o-ring, affected by cold weather, caused the explosion. The aftermath included NASA's safety improvements and annual remembrance of the lost astronauts.
