Two cosmonauts continued the outfitting of a brand new module outdoors the Worldwide Area Station on what was the fiftieth deliberate spacewalk to originate from the Russian section of the orbiting outpost.
For the second time in seven days, Expedition 65 flight engineers Oleg Novitskiy and Pyotr Dubrov, each of the Russian federal house company Roscosmos, donned Orlan spacesuits and exited the Poisk airlock at 10:51 a.m. EDT (1451 GMT) on Thursday (Sept. 9) to start routing cables for the brand new multipurpose laboratory module (MLM), or “Nauka” (“Science”).
Choosing up the place they left off on the finish of their spacewalk on Sept. 3, Novitskiy and Dubrov photographed the antennas on a Progress cargo craft docked to the house station, put in 4 handrails to ease maneuvers on future spacewalks and routed an ethernet cable to allow knowledge to run from the U.S. working section to experiments on the surface of the brand new module.
Though the ethernet cable was efficiently mated, Novitskiy and Dubrov bumped into some problem with the cable reel’s flat round lid. As soon as the quilt was free of the cable, there was a quick debate about whether or not to jettison it as initially deliberate or tie it right down to the outside of the module.
“This form is form of difficult,” one of many spacewalkers stated. “Such an incredible merchandise.”
“And that is the place the flying saucer legends come from,” the cosmonaut joked.
A choice was made to quickly stow the disc after which jettison it with different reuse on the finish of the spacewalk.
Novitskiy and Dubrov then moved on to operating further cable bundles, this time to attach the TV methods and knowledge traces between the Nauka the Zvezda service modules, in addition to one linking up the automated docking methods for future visiting Russian spacecraft, together with the Progress and crewed Soyuz autos.
The 2 cosmonauts then deployed two bio-risk containers that can get hold of knowledge on any bodily or genetic modifications to micro organism, fungi and different microorganisms after being uncovered to the vacuum of house. The experiment is concentrated on higher understanding contaminants that may very well be an element on interplanetary spacecraft.
Novitskiy and Dubrov wrapped up their spacewalk by jettisoning the ethernet cable reel cowl and a chunk of multi-layer insulation additionally eliminated throughout the spacewalk. The 7-hour, 25-minute spacewalk ended at 6:16 p.m. EDT (2216 GMT), because the airlock hatch on the Poisk module was closed.
Autonomously docked to the house station on July 29, the Nauka MLM will present Russian cosmonauts with an expanded space to conduct science and can function a docking port and airlock for Russian spacewalks. The module may also home a further crew quarters and a 3rd bathroom for the station’s residents.
Thursday’s spacewalk was the third for each Novitskiy and Dubrov. Novitskiy was designated extravehicular crew member 1 (EV1) and wore the Russian Orlan spacesuit with crimson stripes. Dubrov, as EV2, wore a spacesuit with blue stripes.
This was Russia’s fiftieth deliberate spacewalk and 58th total performed utilizing Orlan spacesuits outdoors of the Worldwide Area Station. In whole, astronauts and cosmonauts have carried out 243 extravehicular actions (EVA) in help of the meeting and upkeep of the orbiting laboratory.
