In In the Space Station Processing Facility, STS-120 Commander Pamela Melroy (center) learns more about the Node 2, another element to be added to the International Space Station. She and other crew members are at KSC for equipment familiarization. Node 2 will provide a passageway between three station science experiment facilities: the U.S. Destiny Laboratory, the Kibo Japanese Experiment Module, and the European Columbus Laboratory. STS-120 is targeted for launch on October 20. Photo credit: NASA/Kim Shiflett
