In the Space Station Processing Facility at NASA's Kennedy Space Center, workers close the hatch on the Japanese Experiment Module, called Kibo. The closing is in preparation for the transfer to a payload canister and the move to the launch pad. On the mission, space shuttle Discovery will transport the Kibo module and the Japanese Remote Manipulator System, or JEM-RMS, to complete the Kibo laboratory. The launch of Discovery is targeted for April 24. Photo credit: NASA/Kim Shiflett
