KENNEDY SPACE CENTER, FLA. -- In the Vehicle Assembly Building at KSC, a crane moves laterally to carry external tank No. 120 into a checkout cell. The tank will be prepared for stacking with solid rocket boosters to launch Space Shuttle Discovery on mission STS-120 in October. The mission is the 23rd to the International Space Station and will launch an Italian-built, U.S. multi-port module known as Harmony for the station. Christened after a school contest, Harmony will provide attachment points for European and Japanese laboratory modules. NASA/George Shelton
