Endeavour shuttle astronauts Robert Behnken and Nicholas Patrick are back inside the International Space Station after successfully completing all their planned chores for their first spacewalk to deliver the outpost's new Tranquility node and Cupola. They completed their work at 3:49 a.m. EST (0849 GMT).

Total spacewalking time: 6 hours, 32 minutes.

It was the first spacewalk for Patrick and fourth for Behnken, who ended with more than 25 hours of cumulative time working in space. Together, the two astronauts helped install Tranquility (crewmates Terry Virts and Kathryn Hire used the station's robotic arm to actually move it). They also stored some equipment for a later spacewalk and removed an old tool carrier platform from the station's Dextre maintenance robot.
