Roscosmos cosmonauts completed their work in open space and returned to the ISS

November 19, 2020

The egress hatch on the docking compartment of the Poisk module is successfully closed, Roscosmos cosmonauts Sergei Ryzhikov and Sergey Kud-Sverchkov have completed the 47th planned spacewalk (EVA-47). They performed a number of activities to install equipment on the outer surface of the ISS. The egress hatch on the Poisk docking compartment was closed at 01:01:00 Moscow Time on November 19, 2020. The duration of the extravehiclular activity was 6 hours and 47 minutes.

It was the first time when the spacewalk was performed from the docking compartment of the Mini Research Module Poisk. The first opening of the hatch took place at 18:12 Moscow Time. It had never been opened before: The module was launched in 2009, but during all this time cosmonauts used for spacewalks another module, Pirs, which is now being prepared for undocking from the ISS.

A few minutes after that the hatch was closed, cosmonauts re-pressurized up to 260 mm Hg, checked the Poisk module for leaks, dumped pressure and at 18:55 Moscow Time re-opened the hatch. Sergei Ryzhikov was working wearing a commanders outfit with red stripes (spacesuit Orlan-ISS No.5), Sergey Kud-Sverchkov wore a spacesuit with blue stripes (Orlan-ISS No.4). Since both cosmonauts have the same first name, specialists on the ground addressed them as "Sergei first and Sergei second, respectively. Astronauts of the US orbital segment provided support from onboard the International Space Station.

The main objective of the spacewalk was to prepare the station for the arrival of the new Russian module Nauka: For that purpose cosmonauts switched the telemetry system antenna Transit-B from Pirs module to Poisk module. After that they changed the location of sensors of the pressure and residue monitoring unit, installed on the Mini Research Module.

In addition to that, within the framework of space experiment Impact, on the propulsion compartment of the Service Module Zvezda, sample case No.1 was removed and replaced with sample case No.2. This study will eventually allow to very reliable determine contamination levels for scientific instrumentation and systems equipment installed on the outer surface of the space station.

On the ground, at the mission control center of TsNIIMash (a part of state corporation Roscosmos) the spacewalk was monitored by specialists of the Lead Operations Control Team of the ISS RS responsible for the crew extravehicular activities (S.P.Korolev Rocket and Space Corporation Energia). For both cosmonauts it was their first spacewalk, and it was the 55th spacewalk under the Russian program of activities outside the International Space Station. The previous Russian spacewalk took place in late May of 2019.
