The Russian space agency said the International Space Station (ISS) would have to provide extra air once extra-normal volumes began to leak.
Russian media quoted Sergei Krikalev, executive director of Rashcomos, as saying that the air leak had been localized to a part of the service module and that there was no danger to Russian and American crews on board.
The crew is reportedly planning to close the loophole in the coming days.
NASA Earlier it was revealed how the crew aboard the ISS is taking the shape of a small leak problem to wake up by flight controllers which has been seen to increase in size.
NASA astronauts and station commanders Chris Cassidy and Roscomos astronauts Antley Evanshin and Evan Wagner were asked to collect data using an ultrasonic leak detector.
NASA’s Kenny Todd, Deputy Manager ISS, Said Tuesday: “As far as the station goes, we are in very good condition.
“The only issue I will raise at the moment is this little atmospheric leak that has proven to be a bit of a challenge over the last few months.
“But those of you who follow the station to conduct regular orbits, you know we’ve been working on a small atmospheric leak for the last year … well … really for a year.”
He added: “We decided to go ahead and wake up the crew. We went through several hours of activity and we think we got some information again.
“We’ve got a fine point where we think the leak is according to the module. We, at the moment, think it’s in the service module region, it’s in the Russian section. Again, we’re monitoring all the data from the test.
“But what we do know and confirm with our Russian colleagues is that we think something is going on there.”

NASA said in a statement: “The size of the leak identified overnight has since been attributed to temporary temperature changes at the station, leaving the overall rate of leakage unchanged.”
The statement added, “The leak, which has been under investigation for several weeks, did not pose any immediate threat to the crew at the current leak rate and revealed a slight deviation from the crew’s schedule.”
NASA said that once the overnight check was completed, the crew reopened the deficit between the U.S. and Russian divisions and “resumed regular activities.”
Over the weekend, an undressed cargo craft is due to arrive at ISS.
The next three ISS residents are due to leave the world on October 14 to take part in what will be the next 4th mission of the ISS since its inception in 1999.
