Overseas Space 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 Harmony node in its brand new place while watching 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 making the airlock and starting equipment and tools, Whitson removed, vented and stowed an ammonia jumper, section of a cooling loop that is temporary. Removing it permitted connection regarding the hookup for the permanent Loop B ammonia loop that is cooling a 2nd fluid tray in the place’s outside.
Tani meanwhile configured tools, then eliminated two fluid caps to get ready for connection of this cooling that is permanent B.
As with the Nov. 20 spacewalk, a lot of this outing had been 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 from the S0 truss, in the center associated with section’s primary truss, to Destiny, atop the port avionics tray.
While they did because of the Loop The tray Nov. 20, they utilized some sort of relay method, one moving ahead and connecting tethers to prepare yourself to get the tray, then your other going further forward to use the next find a bride net handoff.
After they reached the installation point they bolted along the tray, then installed its six fluid line connections. Cooling Loop B ended up being 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 camera system and eight launch restraints from latch petals of the berthing mechanism that is common. The digital digital digital camera and petals can help dock and initially attach the European area Agency laboratory Columbus, enabling bolts become driven to secure it to its permanent section house through the STS-122 objective of Atlantis month that is next.

Tani relocated to the proper part associated with the primary truss and eliminated among the 22 covers of this starboard Solar Alpha Rotary Joint (SARJ) and did an examination like the one he did during their spacewalk through the mission that is STS-120. He took electronic photos and examples of metallic shavings he found here. He described some surfaces to be abraded.
Whitson meanwhile installed the very last staying connection for the facility to Shuttle energy Transfer System.
That get ahead task finished connections shuttles that are enabling 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 from the SARJ, which have been vibration that is showing increased energy usage.
Tani stowed and bagged the SARJ address outside of the airlock, making the joint readily available for a movie survey with a digital digital digital camera in the place’s robotic Canadarm2. That study are going to be done following the STS-122 objective and can include one or more complete rotation associated with the suspect joint, which includes skilled vibration and increased electric present 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 removed throughout a past spacewalk to clear just how for any other activities.
Whitson and Tani did the standard cleaning process and then joined the airlock. The start of its repressurization marked the formal end of this spacewalk.
