The 16th American assembly flight and 112th overall American flight to the International Space Station (ISS) launched on November 23, 2002 from Kennedy's launch pad 39A aboard the Space Shuttle Orbiter Endeavour STS-113. Mission objectives included the delivery of the Expedition Six Crew to the ISS, the return of Expedition Five crew back to Earth, the delivery of the Crew and Equipment Translation Aid (CETA) cart, and the installation and activation of the Port 1 Integrated Truss Assembly (P1). The first major component installed on the left side of the Station, the P1 truss provides an additional three External Thermal Control System radiators. Weighing in at 27,506 pounds, the P1 truss is 45 feet (13.7 meters) long, 15 feet (4.6 meters) wide, and 13 feet (4 meters) high. Three space walks, aided by the use of the Robotic Manipulator Systems of both the Shuttle and the Station, were performed in the installation of P1. In this photograph, astronauts and mission specialists John B. Herrington (left) and Michael E. Lopez-Alegria (right) work near the CETA cart on a truss on the ISS during a scheduled space walk for the mission. The final major task of the space walk was the relocation of the CETA cart from the Port One (P1) to the Starboard One (S1) Truss, which will allow the Mobile Transporter to move along the P1 to assist in upcoming assembly missions.
