In the Space Station Processing Facility, the mission STS-120 crew members are getting familiar with the Node 2, another element to be added to the International Space Station. Seen here are Mission Specialists Paolo Angelo Nespoli (left) and Douglas H. Wheelock. Nespoli represents the European Space Agency. 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
