The ISS leak "appeared to grow in size," according to a NASA spokesperson.

Like a Sieve

In August, NASA detected a leak on the International Space Station. What followed was several weeks of investigation, including the isolation of crew members into one of the station's Russian modules as an extreme precaution.

Ironically, NASA now believes the leak is located in the main work area of the Zvezda Service Module, the same one that was used for the evacuations.

More alarmingly, according to today's update, ground analysis concluded that the leak "appeared to grow in size" — but it still doesn't pose any immediate danger to the crew. The leak is "only a slight deviation to the crew’s schedule," according to NASA.

"It’s a very, very small leak," Greg Dorth, manager of the ISS Program External Integration Office at NASA, said during a Monday news briefing, as quoted by Spaceflight Now. "It’s an impact to our consumables, but we’ve planned for that. We can address the leak as we continue the investigation."

Crew Switch

The exact location of the leak is still unknown.

Current crew members, NASA's Chris Cassidy and Russian cosmonauts Anatoly Ivanishin and Ivan Vagner used ultrasonic leak detectors to investigate the problem in both the US and Russian segments of the station.

Hopefully, the leak will soon be found by the current crew. Three more astronauts are scheduled to travel to the station on board a Soyuz spacecraft on October 14.

The current crew will then wrap up their mission, making their return journey in the same capsule on October 21.
