The Challenger Learning Center is designed as a realistic mock-up of Mission Control and an orbiting space station. Students join teams at computer consoles or onboard the orbiting space lab, rev up their imaginations, and work together toward the mission's goal, whether it is the launching of a probe or the interception of a comet. Today, Challenger Learning Centers reach about 400,000 students and more than 20,000 teachers per year through a broad array of mission-based activities. We designed and fabricated the first of the Challenger Centers located in Houston, Texas.
