"Sergei Prokopiev and Oleg Kononenko opened the exit hatch of the Pirs docking compartment and started work on the outer surface of the ISS," the Roscosmos report said on Twitter.

It is noted that the estimated time of work should be six hours.

According to RIA Novosti, the astronauts will conduct a survey of the outer surface of the Soyuz MS-09 spacecraft, in which a hole was previously discovered.

On December 3, the successful docking of the Soyuz MS-11 spacecraft with the International Space Station took place. The spacecraft delivered to the ISS cosmonaut "Roscosmos" Oleg Kononenko, astronauts from NASA and the Canadian Space Agency Ann McClain and David Saint-Jacques.
