CAPE CANAVERAL, Fla. –– In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, the Japan Aerospace Exploration Agency's Kibo Exposed Facility, or EF, is moved across the room to transfer it to a workstand. When it is installed on the Kibo laboratory, the EF will provide a multipurpose platform where science experiments can be deployed and operated in the exposed environment. The payloads attached to the EF can be exchanged or retrieved by Kibo's robotic arm, the JEM Remote Manipulator System. The EF, along with the Experiment Logistics Module Exposed Section, will be carried aboard space shuttle Endeavour on the STS-127 mission targeted for launch June 13, 2009.

The Space Shuttle program was the United States government's manned launch vehicle program from 1981 to 2011, administered by NASA and officially beginning in 1972. The Space Shuttle system—composed of an orbiter launched with two reusable solid rocket boosters and a disposable external fuel tank— carried up to eight astronauts and up to 50,000 lb (23,000 kg) of payload into low Earth orbit (LEO). When its mission was complete, the orbiter would re-enter the Earth's atmosphere and lands as a glider. Although the concept had been explored since the late 1960s, the program formally commenced in 1972 and was the focus of NASA's manned operations after the final Apollo and Skylab flights in the mid-1970s. It started with the launch of the first shuttle Columbia on April 12, 1981, on STS-1. and finished with its last mission, STS-135 flown by Atlantis, in July 2011.
