Photo Gallery: Atlantis' payload bay sealed for flight

The 60-foot-long payload bay doors of space shuttle Atlantis are swung shut and latched for flight. The next time the doors will be opened is in orbit, about 90 minutes after launch. Atlantis is carrying the Raffaello cargo-delivery module and a robotic satellite refueling demonstrator payload for the International Space Station, plus a tiny PicoSat that will be ejected from the payload bay.
