Air pressure on the International Space Station has been restored to correct levels after a leak was repaired.
Russia's space agency Roscosmos said in a statement that "the safety and health of the crew are not threatened" following the incident.
The leak, which was discovered on Thursday, was traced to a small hole in one of the Russian Soyuz capsules docked at the station.
Russia's manned space program director Sergei Krikalev said the leak was patched up with a sealant that is "already proving to be airtight".
He said the fracture could be due to a materials flaw or a micrometeorite strike.
Three Americans, two Russians and a German are currently on board the station.
All members of the space station crew arrive and depart on Soyuz capsules.
