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 for the Harmony node in its brand brand brand new place as you’re 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 leaving the airlock and starting equipment and tools, Whitson removed, vented and stowed an ammonia jumper, section of a short-term cooling loop. Eliminating it permitted connection for the hookup associated with permanent Loop B ammonia cooling cycle on a 2nd fluid tray from the place’s outside.
Tani meanwhile configured tools, then removed two fluid caps to organize for connection of this cooling that is permanent B.
Such as 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 mail order bride tray had been relocated from its short-term place in the S0 truss, during the center regarding 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.
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 into 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 procedure. The digital digital digital camera and petals helps dock and initially attach the European area Agency laboratory Columbus, allowing bolts become driven to secure it to its permanent section house throughout the STS-122 objective of Atlantis the following month.

Tani relocated to just the right region of the primary truss and eliminated one of many 22 covers associated with starboard Solar Alpha Rotary Joint (SARJ) and did an examination much 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 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 section energy while docked at Pressurized Mating Adapter-2. She then joined up with Tani in the starboard SARJ, and offered more terms regarding the SARJ, which was in fact vibration that is showing increased energy usage.
Tani stowed and bagged the SARJ cover outside of the airlock, making the joint designed for a video clip study with camera in the place’s robotic Canadarm2. That study are going to be done following the STS-122 objective and certainly will involve a minumum of one 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 into the forward end of Harmony as get-ahead tasks. As another Whitson reinstalled on Destiny a team gear interpretation help light she had eliminated within a previous spacewalk to clear the way in which 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 associated with the spacewalk.
