NASA – Nationwide Aeronautics and Area Management. The spacewalk otherwise had been just like the one
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 regarding the Harmony node with its brand new place at the 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 starting equipment and tools, Whitson removed, vented and stowed an ammonia jumper, section of a cooling loop that is temporary. Getting rid of it permitted connection of this hookup regarding the permanent Loop B ammonia loop that is cooling a 2nd fluid tray from the station’s outside.
Tani meanwhile configured tools, then eliminated two fluid caps to get ready for connection of the permanent cooling Loop B.
Like in the Nov. 20 spacewalk, a lot of this outing ended up being dedicated to make use of 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, during the center for the section’s primary truss, to Destiny, atop the port avionics tray.
While they did aided by the Loop A tray Nov. 20, they utilized a type of relay method, one going ahead and connecting tethers to get ready to get the tray, then your other going further forward to use the next handoff.
When they reached the installation point they bolted down the tray, then installed its six line that is fluid. Cooling Loop B had been effectively restarted later on within 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 camera system and eight launch restraints from latch petals of the berthing mechanism that is common. The 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 through the STS-122 mission of Atlantis month that is next.

Tani relocated to the best region of the primary truss and eliminated among the 22 covers regarding the starboard Solar Alpha Rotary Joint (SARJ) and did an examination much like the one he did during his spacewalk through the mission that is STS-120. He took electronic photos and examples of metallic shavings he discovered here. He described some areas as being abraded.
Whitson meanwhile installed the final connection that is remaining 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 during the starboard SARJ, and offered more terms from the SARJ, which was indeed vibration that is showing increased energy usage.
Tani stowed and bagged the SARJ address outside of the airlock, leaving the joint readily available for a video clip study by digital camera in the place’s robotic Canadarm2. That study is likely to be done after the STS-122 objective and can include a minumum of one complete rotation regarding the suspect joint, which includes experienced vibration and increased electric draw that is current.
Tani relocated an instrument case and relocated an articulated portable base discipline 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 within a past spacewalk to clear the way in which for other tasks.
Whitson and Tani did the standard cleaning process and then joined the airlock mail order brides. The start of its repressurization marked the formal end associated with the spacewalk.
