NASA's Launch Services Program gives the 'go' for launch!
The launch team members assemble at their computer and communication consoles in the Mission Directors Center at Cape Canaveral Air Force Station about three to four hours before the launch.

The NASA launch director is the highest authority during the countdown and provides NASA's "go/no-go" decision to the mission director.

Before liftoff, the launch director checks with the launch team to make sure all the criteria are met and that the payload and rocket are ready to go.
