CAPE CANAVERAL, Fla. -- In the Rotation, Processing and Surge Facility, or RSPF, at NASA's Kennedy Space Center in Florida, a worker performs the propellant grain inspection of the final solid rocket booster segments, which is a required safety analysis. The booster segments were manufactured at the ATK solid rocket booster plant in Promontory, Utah, and traveled to Kennedy along the Florida East Coast Railway. The booster segments will be stacked and then mated to space shuttle Atlantis and its external fuel tank in the Vehicle Assembly Building. The segments will be used for what currently is planned as the 'launch on need,' or potential rescue mission for the final shuttle flight, Endeavour's STS-134 mission.
