KENNEDY SPACE CENTER, FLA. -- In the Space Station Processing Facility at NASA's Kennedy Space Center, the Columbus Laboratory module moves toward the waiting payload canister at right. The canister will transport the module and other payloads to Launch Pad 39A in preparation for its journey to the International Space Station. The European Space Agency 's largest single contribution to the International Space Station, Columbus will expand the research facilities of the station, providing crew members and scientists around the world the ability to conduct a variety of life, physical and materials science experiments. The module is approximately 23 feet long and 15 feet wide, allowing it to hold 10 large racks of experiments. The module is scheduled to be transferred to Launch Pad 39A in early November, in preparation for its journey to the station. Columbus will fly aboard space shuttle Atlantis on the STS-122 mission, targeted for launch Dec. 6.
