The P-1 truss, a component of the International Space Station, arrives in the parking lot outside the Operations and Checkout Building where it will undergo processing. The P-1 truss, scheduled to fly in spring of 2002, is part of a total 10-truss, girder-like structure on the Space Station 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, S0, during the spring assembly flight. The 33,000-pound P-1 will house the thermal radiator rotating joint (TRRJ) that will rotate the Station's radiators away from the sun to increase their maximum cooling efficiency.
