At the Railroad yard at NASA's Kennedy Space Center, solid rocket booster segments from the STS-122 mission are being loaded onto railroad cars and covered for transportation to Utah. After a mission, the spent boosters are recovered, cleaned, disassembled, refurbished and reused after each launch. After hydrolasing the interior of each segment, they are placed on flatbed trucks. The individual booster segments are transferred to a railhead located at the railroad yard. The covered segments will be moved to Titusville for interchange with Florida East Coast Railway to begin the trip back to the Thiokol plant in Wa¬satch, Utah. Photo credit: NASA/Jack Pfaller
