ISS014-E-13301 (4 Feb. 2007) --- Astronaut Sunita L. Williams, Expedition 14 flight engineer, participates in the second of three sessions of extravehicular activity (EVA) in nine days, as construction continues on the International Space Station. During the spacewalk, Williams and Michael E. Lopez-Alegria (out of frame), commander and NASA space station science officer, reconfigured the second of two cooling loops for the Destiny laboratory module, secured the aft radiator of the P6 truss after retraction and prepared the obsolete Early Ammonia Servicer (EAS) for removal this summer.
