Global area facility Commander Peggy Whitson and Flight Engineer Dan Tani finished a 7-hour, 4-minute spacewalk at 11:54 a.m. EST Saturday, continuing the outside outfitting associated with the Harmony node in its brand new place at the U.S. laboratory Destiny.

The spacewalkers completed all scheduled tasks, including another consider the starboard Solar Alpha Rotary Joint, and did some get-ahead act as well. on Nov. 20.
After making the airlock and creating equipment and tools, Whitson removed, vented and stowed an ammonia jumper, section of a cooling loop that is temporary. Eliminating it allowed connection regarding the hookup of this permanent Loop B ammonia cooling cycle on a 2nd fluid tray regarding the place’s outside.
Tani meanwhile configured tools, then eliminated two fluid caps to organize for connection of this cooling that is permanent B.
Such as the Nov. 20 spacewalk, a lot of this outing had been dedicated to make use of a fluid tray, this time around Harmony’s Loop B fluid tray. The 300-pound, 18.5-foot tray ended up being relocated from the short-term place regarding the S0 truss, during the center of this section’s primary truss, to Destiny, atop the port avionics tray.
While they did using the Loop The tray Nov. 20, they used a type of relay strategy, one going ahead and connecting tethers to get ready to get the tray, then your other going farther forward to just take the next handoff.
When they reached the installation point they bolted along the tray, then installed its six line that is fluid. Cooling Loop B was effectively restarted later on within the spacewalk. Whitson configured two Loop B heater cables.
Whitson relocated to your starboard side of Harmony.
