Spacewalkers Bob Behnken and Nicholas Patrick completed a 6-hour, 32-minute spacewalk at 3:49 a.m. EST.
The spacewalking pair finished all their assigned work and some get-ahead tasks. The Tranquility node and cupola were robotically maneuvered from Endeavour’s payload bay then installed onto the port side of the Unity node. Tranquility’s hatch is scheduled to be opened at about 9:14 p.m. tonight.
This was the first of three STS-130 spacewalks, the 231st conducted by U.S. astronauts, the fourth for Behnken and the first for Patrick. It was the 138th in support of International Space Station assembly and maintenance, totaling 861 hours, 34 minutes. It was the 110th spacewalk out of the space station, totaling 674 hours, 19 minutes.
