International Space Station Commander Peggy Whitson and Flight Engineer Dan Tani wound up a 7-hour, 16-minute spacewalk to outfit the Harmony node in its new position in front of the U.S laboratory Destiny at 12:26 p.m. EST Tuesday.

They completed scheduled tasks and did three get-ahead jobs in the spacewalk, which began about 50 minutes early.

After leaving the Quest airlock and setting up tools and equipment, Whitson removed, vented and stowed an ammonia jumper, part of a temporary cooling loop. Removing it allowed connection of the hookup of the permanent ammonia cooling loop on a fluid tray on the station's exterior.
