Roscosmos confirmed the triggering of an emergency alarm in the Russian Zvezda module. However, the incident did not affect the preparation of astronauts for a spacewalk – it is conducted normally.

It is noted that according to the main operational control group of the Russian segment of the station, all systems are working normally, the composition of the air on board is cleaned, the health of the crew is not in danger.
"The crew continues regular training for a spacewalk," the state corporation added.
