MOSCOW. Nov 19 (Interfax) - Russian cosmonauts Sergei Ryzhikov and Sergei Kud-Sverchkov from the International Space Station (ISS) crew have wrapped up their spacewalk lasting about six hours, according to a live broadcast on the website of the Roscosmos State Corporation.
The cosmonauts did not accomplish the task of replacing the fluid flow regulator on the Zarya module after encountering a stuck bolt on the hermetic container storing the new panel.
During the spacewalk, Ryzhikov and Kur-Sverchkov relocated an antenna to the Poisk module from the Pirs docking module, which will be decommissioned and replaced by the new Russian module Nauka. They also installed a new tray for the Impact space experiment on the Zvezda service module.
Acting on instructions from Russia's Mission Control Center, Ryzhikov also inspected the Zvezda module's outer cover at the suspected air leak site and took photos of it. According to the cosmonaut, he has not spotted any signs of external impact in that place.
Ryzhikov and Kud-Sverchkov are expected to conduct another spacewalk in February that will focus on preparations for the arrival of the Nauka module.
In all, it will take approximately ten spacewalks to integrate the Nauka module into the ISS.
The last spacewalk performed by Russian cosmonauts was on May 29, 2019, when Oleg Kononenko and Alexei Ovchinin worked outside the ISS for around six hours.
