Overseas 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 of this Harmony node with its new place as you’re watching U.S. laboratory Destiny.

The spacewalkers completed all tasks that are scheduled 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 starting equipment and tools, Whitson removed, vented and stowed an ammonia jumper, element of a short-term cooling loop. Getting rid of it permitted connection associated with hookup of this permanent Loop B ammonia cooling cycle on a 2nd fluid tray in the section’s outside.
Tani meanwhile configured tools, then eliminated two fluid caps to get ready for connection of the cooling that is permanent B. real mail order brides legit
As with 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 from the S0 truss, in the center associated with section’s primary truss, to Destiny, atop the port avionics tray.
While they did aided by the Loop The tray Nov. 20, they utilized 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 use the next handoff.
After they reached the installation point they bolted down the tray, then installed its six line that is fluid. Cooling Loop B ended up being effectively restarted later on into the spacewalk. Whitson configured two Loop B heater cables.
Whitson relocated to your side that is starboard of. There she eliminated a thermal address of a centerline berthing digital camera system and eight launch restraints from latch petals of a typical berthing device. The digital digital digital camera and petals may help dock and initially attach the European area Agency laboratory Columbus, allowing bolts become driven to secure it to its permanent section house through the STS-122 objective of Atlantis the following month.

Tani moved to the best part for the primary truss and removed one of several 22 covers associated with the starboard Solar Alpha Rotary Joint (SARJ) and did an assessment just like the one he did during their spacewalk through the STS-120 mission. He took pictures that are digital types of metallic shavings he discovered there. He described some areas as being abraded.
Whitson meanwhile installed the very last connection that is remaining the facility to Shuttle energy Transfer System.
That get ahead task finished connections allowing shuttles Discovery and Endeavour to get place energy while docked at Pressurized Mating Adapter-2. She then joined up with Tani during the starboard SARJ, and offered more words on the SARJ, which have been showing vibration and increased energy usage.
Tani bagged and stowed the SARJ address outside of the airlock, making the joint designed for a video clip study with digital digital camera in the station’s robotic Canadarm2. That study will soon be done following the STS-122 objective and can include a minumum of one complete rotation of this suspect joint, which includes skilled vibration and increased electric current draw.
Tani relocated an instrument case and relocated an articulated foot that is portable to your forward end of Harmony as get-ahead tasks. As another Whitson reinstalled on Destiny a team gear interpretation help light she had eliminated throughout a past spacewalk to clear the way in which for any other tasks.
Whitson and Tani did the cleanup that is standard and then joined the airlock. The start of its repressurization marked the end that is official of spacewalk.
