Forty years ago, the nation was watching as the space shuttle Challenger began its ascent on a cold Florida morning, headed for the stars. Tragedy followed. Just 73 seconds after launch, O-ring seals in a rocket booster failed, causing a disaster that claimed the lives of the seven astronauts on board. While the fatal accident profoundly altered the nation’s space program, it also sparked a powerful and enduring mission led by the astronauts’ families: to inspire young people through education, curiosity and exploration. That mission lives on today through Challenger Learning Centers across the country, including the Challenger Learning Center of Tallahassee.
