Inside the Vehicle Assembly Building, an overhead crane lifts the forward section of a solid rocket booster (SRB) to mate it with the components seen at lower left in the photo. The forward section of each booster, from nose cap to forward skirt contains avionics, a sequencer, forward separation motors, a nose cone separation system, drogue and main parachutes, a recovery beacon, a recovery light, a parachute camera on selected flights and a range safety system. Each SRB weighs approximately 1.3 million pounds at launch. The SRB is part of the stack for Space Shuttle Discovery and the STS-92 mission, scheduled for launch Oct. 5, from Launch Pad 39A, on the fifth flight to the International Space Station
