The next morning, the team probably woke up to some surprising (and slightly worrying) news, and all crew members went searching for the hole.
Meanwhile, Roscosmos (Russian Space Agency) has convened a commission to conduct further analysis of the possible cause of the leak.
On Wednesday night, flight controllers detected a tiny leak on one of two Russian Soyuz spacecraft attached to the complex, as the Expedition 56 crew slept.
In 2007, another leak occurred in the station's Harmony module in the USA section but officials said at the time the leak was no cause for concern. Earlier this week, a small hole on the Russian side of the International Space Station (ISS) sprung a leak.
In 2016, NASA stated that the Agency has no plans to renew the contract with "Roskosmos" for delivery of astronauts to the ISS after 2018. As of 8 a.m., the crew was working to patch it more permanently.More news: EPL: Sarri speaks on reverting to Conte's style of play at Chelsea

Astronauts aboard the International Space Station (ISS) have reportedly managed to plug a 2mm hole in the structure, after it was hit by space junk or a micrometeorite.
The issue started at 7PM EDT last night when flight controllers for the ISS noted signs of a "minute pressure leak".
The Soyuz capsule that was leaking, one of the two at the station, arrived at the lab in June, carrying three astronauts.
As reported by the Inquisitr, the ISS experienced a reduction in cabin pressure on August 29, discovered by flight controllers at Mission Control centers in both Houston and Moscow.
The hole is actually located on a part of the space craft which doesn't actually return to Earth, so they couldn't bring it down to fix and send back up.
The orbiting space station is cruising 250 miles above the Earth and is on constant alert for the dangers of meteorites and other space debris.
