At night on February 14, 2010 American astronauts Robert Behnken and Nicholas Patrick completed the second of three spacewalks planned for the STS-130 mission.
They left the station at 02:20 UTC and completed a 5 hour, 54 minute spacewalk at 08:14 UTC.
They spent the first part of the spacewalk connecting two ammonia loops, with two lines in each loop, from the Destiny module to Tranquility, hooking the new module to the station’s cooling system, and opened one of those loops to initiate cooling of the module. Then they installed thermal covers on Tranquility’s keel pin and trunnions, to prevent condensation inside the module, outfitted the nadir docking port of Tranquility for the relocation of the cupola module, and installed handrails.
The pair completed all their scheduled tasks.
This was the second of three STS-130 spacewalks, the 232nd conducted by U.S. astronauts, the fifth for Behnken and the second for Patrick. It was the 139th in support of International Space Station assembly and maintenance.
