KENNEDY SPACE CENTER, FLA. - In Orbiter Processing Facility bay 3, STS-120 crew members practice handling tools they will use during the mission. Around the table, at center, dressed in blue flight suits are Mission Specialists Scott E. Parazynski, Douglas H. Wheelock, Paolo A. Nespoli and Expedition 16 Flight Engineer Daniel M. Tani. Between Wheelock and Nespoli is Allison Bolinger, an EVA technician with NASA. In the foreground is Dina Contella, a thermal protection system specialist with NASA. Nespoli is a European Space Agency astronaut from Italy. The STS-120 crew is at Kennedy for a crew equipment interface test, or CEIT, which includes harness training, inspection of the thermal protection system and camera operation for planned extravehicular activities, or EVAs. The STS-120 mission will deliver the Harmony module, christened after a school contest, which will provide attachment points for European and Japanese laboratory modules on the International Space Station. Known in technical circles as Node 2, it is similar to the six-sided Unity module that links the U.S. and Russian sections of the station. Built in Italy for the United States, Harmony will be the first new U.S. pressurized component to be added. The STS-120 mission is targeted to launch on Oct. 20. Photo credit: NASA/George Shelton
