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 for the Harmony node in its brand new place at the U.S. laboratory Destiny.

The spacewalkers completed all tasks that are scheduled including another glance at the starboard Solar Alpha Rotary Joint, and did some get-ahead act as well. on Nov. 20.

After leaving the airlock and starting tools and equipment, Whitson removed, vented and stowed an ammonia jumper, element of a cooling loop that is temporary. Getting rid of it permitted connection for the 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 this permanent cooling Loop B.

Such as the Nov. 20 spacewalk, most of this outing ended up being dedicated to use a fluid tray, this time around Harmony’s Loop B fluid tray. The 300-pound, 18.5-foot tray ended up being moved from the temporary place regarding the S0 truss, in the center associated with the place’s primary truss, to Destiny, atop the port avionics tray.

Because they did aided by the Loop A tray Nov. 20, they utilized some sort 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.

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 when you look at 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 typical berthing device. Meer lezen
