NASA astronaut Nicholas Patrick, STS-130 mission specialist, participates in the mission's third and final session of extravehicular activity as construction and maintenance continue on the International Space Station. During the five-hour, 48-minute spacewalk, Patrick and astronaut Robert Behnken (out of frame), mission specialist, completed all of their planned tasks, removing insulation blankets and removing launch restraint bolts from each of the Cupola's seven windows.
