ESA astronaut Paolo Nespoli (left), STS-120 mission specialist, and astronaut Daniel M. Tani, Expedition 15 flight engineer, converse as they await the start of a post insertion/de-orbit training session in one of the full-scale trainers (out of frame) in the Space Vehicle Mockup Facility at NASA's Johnson Space Center (JSC). Nespoli and Tani are wearing training versions of their Shuttle launch and entry suit. Tani will join Expedition 15 as flight engineer after launching to the International Space Station aboard Discovery on mission STS-120 and is scheduled to return home aboard Atlantis on mission STS-122.
