NASA said that construction of the International Space Station is one step closer to completion with the new addition during the spacewalk by mission specialists Robert Curbeam and Christer Fuglesang.
The spacewalk began at 3:31 p.m. EST (2031 GMT) and lasted more than six hours. First, mission specialist Joan Higginbotham used the station's robotic arm to move the new segment with only inches of clearance into its installation position. Then, the spacewalkers guided Higginbotham with visual cues as the exacting operation was carried out.
After the main attachment task, Curbeam and Fuglesang finalized the installation with power, data and heater cable connections. They also replaced a malfunctioning camera on the other truss of station.
Two more spacewalks are on tap for Discovery's STS-116 mission to reconfigure and redistribute power on the station.
