During the spacewalk, they will check the air tightness of the exit hatch of the Poisk Mini-Research Module 2, replace the removable panel of the liquid flow regulator on the Zarya cargo module, clean the window of the Zvezda module and more, Roscosmos specified
Russian cosmonauts Sergei Ryzhikov and Sergei Kud-Sverchkov currently working aboard the International Space Station (ISS) will float out of the orbital outpost and spend about six hours in their extravehicular activity on November 18, the State Space Corporation Roscosmos told TASS on Friday.
"Overall, the crew’s work on the station’s external surface will take about six hours," the Russian space agency said.
During their spacewalk, the cosmonauts will check the air tightness of the exit hatch of the Poisk Mini-Research Module 2, replace the removable panel of the liquid flow regulator on the Zarya cargo module, clean the window of the Zvezda module and carry out work under the scientific program, Roscosmos specified.
The Russian space agency cosmonauts will also switch over the Transit-B antennae from the Pirs module to the Poisk Mini-Research Module 2 and change the position of the sensors of the pressure and contamination control device installed on the Poisk module, Roscosmos said.
Roscosmos earlier announced that cosmonauts Sergei Ryzhikov and Sergei Kud-Sverchkov would make a spacewalk on November 18.
NASA TV Coverage Set for Russian Spacewalk
Two Russian cosmonauts are scheduled to go outside the International Space Station Wednesday, Nov. 18, to conduct a spacewalk that will initiate preparations for the arrival of a new Russian research module.
Expedition 64 Commander Sergey Ryzhikov and Flight Engineer Sergey Kud-Sverchkov, both of the Russian space agency Roscosmos, will exit the space station through the Poisk module on the space-facing side of the station’s Russian segment for the spacewalk, which is expected to last up to six hours. NASA astronaut Kate Rubins will help the cosmonauts suit up and will monitor their progress.
Live coverage of the Russian spacewalk will begin at 8:30 a.m. EST on NASA Television and the agency’s website. The spacewalk is expected to begin about 9:30 a.m.
Ryzhikov, designated extravehicular crew member 1 (EV1), will wear a Russian Orlan spacesuit with red stripes, and Kud-Sverchkov will wear a spacesuit with blue stripes as extravehicular crew member 2 (EV2). This will be the 47th Russian spacewalk for assembly and maintenance of the station.
During the spacewalk, Ryzhikov and Kud-Sverchkov will first conduct leak inspections outside the hatch, as this will be the first spacewalk using the Poisk module for its purpose as an airlock. Next, they will relocate an antenna from another module, the Pirs docking compartment, to Poisk, the first in a series of tasks over the course of several spacewalks that will prepare Pirs for decommissioning, undocking, and disposal. The Earth-facing Pirs will be replaced by the new Russian Multipurpose Laboratory Module, named “Nauka,” Russian for “science,” which is being prepared for launch at the Baikonur Cosmodrome in Kazakhstan.
The cosmonauts also will replace a fluid flow regulator on the Zarya module, retrieve hardware that measures space debris impacts, and reposition an instrument used to measure the residue from thruster firings.
This will be the first spacewalk for both cosmonauts; the 232nd spacewalk in support of space station assembly, maintenance, and upgrades; and the eighth spacewalk of 2020.
