Another end-of-an-era event heralding the conclusion of the space shuttle program: the final set of space shuttle solid rocket booster segments arrived at the Kennedy Space Center on Thursday, May 27, 2010. The segments were carried on railway cars from the ATK factory in Utah where the boosters are built. The last part of the trip from Jacksonville, Florida included passenger cars carrying NASA personnel and ATK officials, including astronaut Mike Massimino, shuttle launch director Mike Leinbach, and the "voice" of NASA TV, George Diller. The train stopped across the Indian River from KSC where the tracks lead to the Vehicle Assembly Building.
