Russian cosmonauts Sergei Prokopiev and Dmitry Petelin returned to the International Space Station (ISS) after completing their work in space to transfer the airlock to the Nauka module using the manipulator. Roscosmos.
The message says that at 06.11 Moscow time, Prokopiev and Petelin, members of the 69th long-term expedition to the ISS, closed the exit hatch of the Poisk small research module. The duration of the spacewalk was 7 hours 11 minutes.
During the study, the cosmonauts transferred the lock chamber from the Rassvet module to the Nauka module using the European ERA manipulator. Cosmonaut Andrey Fedyaev from the ISS controlled the movements of the robotic arm.
The airlock could not be attached to the module in automatic mode due to the catching latches not working due to the uneven position of the airlock during docking. Experts on Earth decided to put the manipulator into “compatibility” mode, after which Prokopyev and Petelin manually corrected the orientation of the lock chamber relative to the module, and then successfully inserted it.
For the third time during the earlier expeditions of Prokopiev and Petelin appeared into space.
