Mission Specialists Richard A. Mastracchio and Dafydd R. Williams undertook the first EVA of STS-118, marking the first time that either astronaut had spacewalked. Over the course of 6 hours and 17 minutes, the pair worked to install and activate the 1.58-ton (1.4-tonne or 1,433-kilogram), 11-by-14-foot (3.33-by-4.3-meter) S5-truss segment and to retract the forward heat-rejecting radiator from the P6 Truss. NASA planned to relocate the forward heat-rejecting radiator to the end of the port truss during the upcoming STS-120. Pilot Charles O. Hobaugh assisted Williams and Mastracchio from inside the ISS, operating the ISS’s robotic arm, which held the truss.
