NASA – Nationwide Aeronautics and Area Management. The spacewalk otherwise ended up being much like the one

Function

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 with its brand brand new place as you’re 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 leaving the airlock and creating equipment and tools, Whitson removed, vented and stowed an ammonia jumper, section of a short-term cooling loop. Eliminating it permitted connection regarding the hookup associated with permanent Loop B ammonia cooling cycle on a 2nd fluid tray regarding 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, most of this outing ended up being dedicated to make use of a fluid tray, this time Harmony’s Loop B fluid tray. The 300-pound, 18.5-foot tray had been relocated from its short-term place regarding the S0 truss, in the center of this section’s primary 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 down the tray, then installed 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 side that is starboard of. There she eliminated a thermal address of a centerline berthing digital digital camera system and eight launch restraints from latch petals of a typical berthing device. The digital digital camera and petals can help dock and initially attach the European Space Agency laboratory Columbus, allowing bolts become driven to secure it to its permanent section house through the STS-122 objective of Atlantis month that is next.

Tani moved to just the right region of the primary truss and eliminated among the 22 covers for the starboard Solar Alpha Rotary Joint (SARJ) and did an examination much like the one he did during their spacewalk through the mission that is STS-120. He took electronic pictures and examples of metallic shavings he discovered here. He described some areas to be abraded.

Whitson meanwhile installed the last staying connection for the facility to Shuttle energy Transfer System.

That get ahead task finished connections allowing shuttles Discovery 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 regarding the SARJ, which was in fact showing vibration and increased energy consumption.

Tani bagged and stowed the SARJ address outside of the airlock, making the joint designed for a video clip survey by way of camera regarding the place’s robotic Canadarm2. That study will undoubtedly be done following the STS-122 objective and certainly will include one or more complete rotation for the suspect joint, which includes experienced vibration and increased electric draw that is current.

Tani relocated an instrument case and relocated an articulated foot that is portable to your 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 standard cleaning process and then joined the airlock. The start of its repressurization marked the end that is official of spacewalk.
