On January 28, 1986, the Space Shuttle Challenger lifted off from Kennedy Space Center in Florida. Aboard were seven crew members, including Christa McAuliffe, a schoolteacher selected to become the first participant in NASA’s Teacher in Space Project. Millions of Americans watched the launch, which represented both a scientific achievement and an opportunity to bring space exploration closer to ordinary people.
For the first few moments, everything appeared normal. Then, just 73 seconds after liftoff, Challenger broke apart in the sky. The disaster claimed all seven crew members and shocked a nation that had come to regard spaceflight as an increasingly routine activity. The shuttle program was suspended, and a presidential commission was established to determine what had gone wrong.
The investigation revealed that the disaster had not resulted from one sudden, unforeseeable malfunction. A critical seal in the right solid rocket booster had failed, allowing hot gases to escape and ultimately compromising the shuttle’s structural integrity. The technical explanation, however, was only one part of a much larger story. Engineers had expressed concerns about the seals before launch, particularly under unusually cold conditions.
How could a spacecraft carrying seven people have been launched when its engineers had serious reservations about an essential component? Answering that question required more than examining the wreckage. It required investigating the decisions, assumptions and communication failures that had made the launch possible.
Among those tasked with uncovering the truth was Richard Feynman, the Nobel Prize-winning physicist known for his curiosity and impatience with explanations that did not withstand scrutiny. His investigation would demonstrate that the most important question was not merely what had broken, but why the warning signs had failed to prevent the disaster.
