Main: NASA astronaut Robert Behnken, STS-130 mission specialist, participates in the mission's second session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. During the five-hour, 54-minute spacewalk, Behnken and astronaut Nicholas Patrick (out of frame), mission specialist, connected two ammonia coolant loops, installed thermal covers around the ammonia hoses, outfitted the Earth-facing port on the Tranquility node for the relocation of its Cupola, and installed handrails and a vent valve on the new module. Inset: STS-130 mission specialist Robert Behnken is photographed through the Node 3 / Tranquility nadir hatch window during Expedition 22 / STS-130 Extravehicular Activity 2 (EVA 2). The two photographs are timestamped to the same minute. Merged with Photoshop.
