Expedition 65 flight engineers Oleg Novitskiy and Pyotr Dubrov of the Russian place of dwelling agency Roscosmos on Friday (Sept. 2) connected energy and records cables for the fresh multipurpose laboratory module (MLM), also continuously referred to as “Nauka” (or “Science” in Russian).
Novitskiy and Dubrov began the seven-hour, 54-minute spacewalk at 10: 41 a.m. EDT (1441 GMT) by opening the hatch on the Poisk mini-review module positioned adjoining to the Nauka module on the Russian section of the place of dwelling build. After gathering their instruments, the cosmonauts deployed the Strela telescoping tell, a 46-foot-long (14 meters) manually operated crane that they former to traverse the build’s Russian modules.

Retrieving two bundles of four cables each and every, the spacewalkers connected the U.S. operating section’s energy supply to a patch panel on Nauka and to an interface panel on the Zarya helpful cargo block. The cosmonauts ran into some topic eradicating keeping discontinue caps from a few of the main cables but were capable of get cling of all of them freed and the cables plugged in.
The eight cables tied Nauka into the U.S. photo voltaic panel-fed machine that presents electricity for the entire place of dwelling build. Electrical checks performed after the cables were in place of dwelling confirmed a just connection and energy flowing as anticipated.
Novitskiy and Dubrov also began the routing of an ethernet cable to Nauka and partly build in a fresh handrail to ease future spacewalks.
Launched on July 21 and autonomously docked to the place of dwelling build eight days later, the Nauka module will provide an expanded place of dwelling to habits science, to boot to lend a hand as a docking port and airlock for Russian spacewalks. The MLM can even residence extra crew quarters and a bathroom for the place of dwelling build’s residents.
Running a little bit within the lend a hand of schedule as a outcomes of the extra work main to free the cable caps, Novitskiy and Dubrov were suggested by Moscow Mission Control to defer installing two handrails and three natural science experiments to a later spacewalk. Novitskiy and Dubrov wrapped their work by stowing the Strela tell.
The spacewalk ended at 6: 35 p.m. EDT (2235 GMT), as the airlock hatch on the Poisk module develop into once closed.
Friday’s spacewalk develop into once the 2d for both Novitskiy and Dubrov, who beforehand performed their first extravehicular assignment (EVA) together in June. The two are scheduled to work launch air the place of dwelling build once more to proceed the outfitting of Nauka on Thursday (Sept. 9).
Novitskiy, who develop into once designated extravehicular crew member 1 (EV1), wore the Russian Orlan spacesuit with crimson stripes. Dubrov wore a spacesuit with blue stripes as EV2.
This develop into once the 242nd EVA in enhance of Global Set up Set up meeting, upkeep and upgrades and the 10th spacewalk launch air the outpost in 2021.
