In the Space Station Processing Facility at NASA's Kennedy Space Center, members of the STS-124 crew look over the scientific airlock in the Kibo pressurized module. The module is part of the payload for the mission, targeted for launch no earlier than April 24. The crew comprises seven: Commander Mark Kelly, Pilot Kenneth Ham, and Mission Specialists Karen Nyberg, Ronald Garan, Michael Fossum and Akihiko Hoshide. The crew is at Kennedy for a crew equipment interface test that includes familiarization with tools and equipment that will be used on the mission. The STS-124 mission is the second of three flights that will launch components to complete the Japanese pressurized module, the Kibo laboratory. The mission will include two spacewalks to install the new lab and its remote manipulator system. The lab's logistics module, which will have been installed in a temporary location during STS-123, will be attached to the new lab. Photo credit: NASA/Kim Shiflett
