Expedition 14 Commander Michael E. Lopez-Alegria and Flight Engineer Sunita L. Williams conducted their second spacewalk in four days, to finish connecting cooling lines to a permanent system of the ISS. Working for just over 7 hours, the astronauts rerouted a series of two electrical cables and four quick-disconnect fluid lines to the Destiny laboratory’s permanent cooling system; retracted the aft heat-rejecting radiator on the P6 Truss; and finished disconnecting and stowing the second of two fluid lines for the Early Ammonia Servicer. Lopez- Alegria photographed the starboard solar array and the blanket box into which it folds, so that engineers could analyze the photos and finalize plans for its retraction during the Shuttle Mission [[STS-117, scheduled for March 2007. He also removed a sunshade that the crew no longer needed from a data-relay box, folding the sunshade to bring it inside the ISS, so that the crew could dispose of it later. At the conclusion of the spacewalk, Williams and Lopez-Alegria again followed precautionary decontamination procedures in the ISS’s airlock, as they had on 31 January, because they had seen ammonia flakes early in the spacewalk. Williams set a record for spacewalking time accrued by a woman—22 hours and 37 minutes—surpassing the record that NASA astronaut Kathryn C. Thornton had set in 1993.
