The STS-127 payload includes the Japan Aerospace Exploration Agency's Kibo Exposed Facility and the Experiment Logistics Module Exposed Section of the International Space Station. They will be installed on the Kibo laboratory already on the station. Launch of the STS-127 mission is targeted for June 13. Photo credit: NASA/Tim Jacobs
