On July 26, 2000 the P-1 truss arrived at Kennedy Space Center's Shuttle Landing Facility aboard its "Super Guppy" transport. A flatbed truck was backed up to begin the off loading of the P-1 truss in preparation for movement to the Operations and Checkout Building for processing. The P-1 truss, scheduled to fly in spring of 2002, is part of a total 10-truss, girder-like structure that will ultimately extend the length of a football field. Astronauts will attach the 14-by-15 foot structure to the port side of the center truss, SO, during the spring assembly flight. The 33,000-pound P-1 will house the thermal radiator rotating joint (TRRJ) that will rotate the International Space Station's radiators away from the sun to increase their maximum cooling efficiency.
