STS-29 Discovery, OV-103, solid rocket booster (SRB) preparation at KSC

STS-29 Discovery, Orbiter Vehicle (OV) 103, solid rocket booster (SRB) right aft segment is being prepared for stacking in the Kennedy Space Center (KSC) Vehicle Assembly Building (VAB). Technicians examine and work with SRB seal from scaffolding platform. The twin sets of boosters provide 80 percent of the space shuttle launch thrust. Each SRB is made up of four "loaded" or fueled segments. The SRBs operate in parallel with the space shuttle main engines (SSMEs) for the first two minutes of flight providing additional thrust needed to escape the gravitational pull of the Earth. At an altitude of approximately 24 nautical miles, the SRBs separate, descend on parachutes, and land in the Atlantic Ocean where they are recovered and reused on future flights.
