At NASA's Kennedy Space Center in Florida, the Space Shuttle Program's final solid rocket booster assembly is stationed in the transfer aisle of the Vehicle Assembly Building. The right and left forward assemblies, which were refurbished and processed at Kennedy, are comprised of three components -- nose cap, frustum and forward skirt. Inside the Vehicle Assembly Building, the boosters will be stacked and then joined to an external fuel tank and space shuttle Atlantis for the STS-135 mission to the International Space Station. STS-135 is targeted to launch June 28, and will be the last spaceflight for the Space Shuttle Program. Photo credit: NASA/Frank Michaux
