Two cosmonauts accomplished the primary in a collection of spacewalks wanted to outfit a newly-added Russian module to the Worldwide Area Station.
Expedition 65 flight engineers Oleg Novitskiy and Pyotr Dubrov of the Russian house company Roscosmos on Friday (Sept. 2) linked energy and information cables for the brand new multipurpose laboratory module (MLM), additionally known as “Nauka” (or “Science” in Russian).
Novitskiy and Dubrov started the seven-hour, 54-minute spacewalk at 10:41 a.m. EDT (1441 GMT) by opening the hatch on the Poisk mini-research module situated adjoining to the Nauka module on the Russian section of the house station. After gathering their instruments, the cosmonauts deployed the Strela telescoping growth, a 46-foot-long (14 meters) operated by hand crane that they used to traverse the station’s Russian modules.

Retrieving two bundles of 4 cables every, the spacewalkers linked the U.S. working section’s energy provide to a patch panel on Nauka and to an interface panel on the Zarya useful cargo block. The cosmonauts bumped into some issue eradicating protecting finish caps from a few of the cables however had been in a position to get all of them freed and the cables plugged in.
The eight cables tied Nauka into the U.S. photo voltaic panel-fed system that gives electrical energy for the whole house station. Electrical checks performed after the cables had been in place confirmed a very good connection and energy flowing as anticipated.
Novitskiy and Dubrov additionally started the routing of an ethernet cable to Nauka and partially put in a brand new handrail to ease future spacewalks.
Launched on July 21 and autonomously docked to the house station eight days later, the Nauka module will present an expanded space to conduct science, in addition to function a docking port and airlock for Russian spacewalks. The MLM may even home further crew quarters and a rest room for the house station’s residents.
Operating barely not on time on account of the additional work wanted to free the cable caps, Novitskiy and Dubrov had been instructed by Moscow Mission Management to defer putting in two handrails and three organic science experiments to a later spacewalk. Novitskiy and Dubrov wrapped their work by stowing the Strela growth.
The spacewalk ended at 6:35 p.m. EDT (2235 GMT), because the airlock hatch on the Poisk module was closed.
Friday’s spacewalk was the second for each Novitskiy and Dubrov, who beforehand carried out their first extravehicular exercise (EVA) collectively in June. The 2 are scheduled to work outdoors the house station once more to proceed the outfitting of Nauka on Thursday (Sept. 9).
Novitskiy, who was designated extravehicular crew member 1 (EV1), wore the Russian Orlan spacesuit with crimson stripes. Dubrov wore a spacesuit with blue stripes as EV2.
This was the 242nd EVA in assist of Worldwide Area Station meeting, upkeep and upgrades and the tenth spacewalk outdoors the outpost in 2021.
