NASA – National Aeronautics and Area Management. The spacewalk otherwise had been much like the one
Global area Station 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 of this Harmony node in its brand new place at the U.S. laboratory Destiny.

The spacewalkers completed all tasks that are scheduled including another go through the starboard Solar Alpha Rotary Joint, and did some get-ahead act as well. on Nov. 20.
After leaving the airlock and starting equipment and tools, Whitson removed, vented and stowed an ammonia jumper, element of a cooling loop that is temporary. Getting rid of it allowed connection associated with the hookup associated with the permanent Loop B ammonia loop that is cooling a 2nd fluid tray regarding the place’s exterior.
Tani meanwhile configured tools, then eliminated two fluid caps to organize for connection of the permanent cooling Loop 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 had been relocated from the short-term place in the S0 truss, during the center for the place’s primary truss, to Destiny, atop the port avionics tray.
While they did aided by the Loop The tray Nov. 20, they utilized some sort of relay method, one going ahead and connecting tethers to prepare yourself to get the tray, then other going further forward to use the next handoff.
After they reached the installation point they bolted along the tray, then installed its six fluid line connections. Cooling Loop B had been effectively restarted later on within the spacewalk. Whitson configured two Loop B heater cables.
Whitson relocated to your starboard side of Harmony. There she eliminated a thermal address of the centerline berthing digital camera system and eight launch restraints from latch petals of the typical berthing device. (more…)
