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 with its brand brand brand new place while 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 allowed connection of this hookup associated with permanent Loop B ammonia loop that is cooling a 2nd fluid tray from 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.
like in the Nov. 20 spacewalk, most 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 ended up being relocated from the short-term place in the S0 truss, in the center for the section’s main truss, to Destiny, atop the port avionics tray.
They used a kind of relay technique, one moving ahead and attaching tethers to be ready to receive the tray, then the other moving farther forward to take the next handoff as they did with the Loop A tray Nov. 20.
When they reached the installation point they bolted along the tray, then connected its six line that is fluid. Cooling Loop B ended up being effectively restarted later on when you look at the spacewalk. Whitson configured two Loop B heater cables.
Whitson relocated to the starboard side of Harmony. There she eliminated a thermal address of a centerline berthing digital camera system and eight launch restraints from latch petals of a typical berthing apparatus. The 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 place house throughout the STS-122 objective of Atlantis the following month.

Tani relocated to the best region of the primary truss and eliminated among the 22 covers for the starboard Solar Alpha Rotary Joint (SARJ) and did an examination just like the one he did during their spacewalk through the STS-120 mission. He took electronic pictures and types of metallic shavings he discovered here. Some surfaces were described by him as being abraded.
Whitson meanwhile installed the very last connection that is remaining the facility to Shuttle Power Transfer System.
That get ahead task finished connections shuttles that are enabling and Endeavour to get section 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 have been vibration that is showing increased energy usage.
Tani stowed and bagged the SARJ address away from airlock, leaving the joint readily available for a video clip study with camera regarding the place’s robotic Canadarm2. That study will likely to be done following the STS-122 objective and certainly will include one or more full rotation regarding the suspect joint, which includes skilled vibration and increased electric draw that is current.
Tani mail-order-bride.org sign in relocated an instrument case and relocated an articulated foot that is portable towards the forward end of Harmony as get-ahead tasks. A crew equipment translation aid light she had removed during a previous spacewalk to clear the way for other activities as another Whitson reinstalled on Destiny.
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.
