STS-113

STS-113 was an Assembly Mission (11A) to the International Space Station, delivering the P1 Truss segment, which provides structural support for the Space Station radiators. Mission Specialists John Herrington and Michael López-Alegría performed three spacewalks to activate and outfit the P1. The STS-113 crew and both Expedition crews transferred about 1,969 kilograms (4,340 pounds) of cargo between the shuttle and station.
