Meet the Launch Team
Launch Team members share the responsibility and excitement of launching space shuttle missions. They report to their respective computer or communication consoles following the "call to stations" for the final countdown. Many of the consoles are located in the firing rooms in Kennedy's Launch Control Center, next door to the Vehicle Assembly Building in Launch Complex 39. Here are some of the key members with descriptions of their responsibilities during the events that lead up to the liftoff of a space shuttle orbiter.
