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 in its brand brand new position while watching U.S. laboratory Destiny.

The spacewalkers completed all scheduled tasks, including another go through 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 permitted connection of this hookup associated with the permanent Loop B ammonia loop that is cooling a 2nd fluid tray in the mail order brides section’s outside.
Tani meanwhile configured tools, then eliminated two fluid caps to get ready for connection of this permanent cooling Loop B.
As with the Nov. 20 spacewalk, a lot of this outing ended up being dedicated to utilize 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, in the center of this place’s primary truss, to Destiny, atop the port avionics tray.
Because they did using the Loop The tray Nov. 20, they utilized a type of relay strategy, one going ahead and attaching tethers to get ready to get the tray, then your other going further forward to use the next handoff.
Once they reached the installation point they bolted along the tray, then hooked up its six fluid line connections. Cooling Loop B ended up being effectively restarted later when you look at 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 the centerline berthing digital camera system and eight launch restraints from latch petals of the typical berthing process. The digital camera and petals can help dock and initially attach the European area Agency laboratory Columbus, allowing bolts become driven to secure it to its permanent place house through the STS-122 objective of Atlantis month that is next.

Tani relocated to just the right side of this primary truss and eliminated among the 22 covers for the starboard Solar Alpha Rotary Joint (SARJ) and did an assessment much like the one he did during their spacewalk through the mission that is STS-120. He took pictures that are digital types of metallic shavings he discovered here. 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 shuttles that are enabling and Endeavour to receive place energy while docked at Pressurized Mating Adapter-2. She then joined up with Tani during the starboard SARJ, and offered more terms from the SARJ, which was in fact showing vibration and increased power usage.
Tani stowed and bagged the SARJ address outside of the airlock, making the joint designed for a movie study by digital digital camera regarding the section’s robotic Canadarm2. That study would be done following the STS-122 objective and certainly will include a minumum of one full rotation regarding the suspect joint, which includes skilled vibration and increased electric draw that is current.
Tani relocated something bag 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 just how for any other tasks.
Whitson and Tani did the standard cleaning process and then joined the airlock. The start of its repressurization marked the formal end for the spacewalk.
