NASA says cabin pressure is holding steady on the International Space Station after crews repaired a small hole in one of the Soyuz spacecraft attached to it.
Flight controllers noticed a drop in air pressure overnight on Wednesday, and alerted the crew.
After monitoring the situation for the better part of an hour, the space station crew pressed a sealant-laden wipe into the leak site to firm up the temporary patch.
Russian officials said the pressure was detected on August 29 and is believed to be in the Soyuz capsule docked at the space station.
However, the cabin crew wasn't in any kind of danger.
In a statement, the agency said: "Throughout the day, the crew was never in any danger, and was told no further action was contemplated for the remainder of the day".More news: U.S. whistleblower Chelsea Manning to be barred from entering Australia
As of today, things went back to normal and the six astronauts living on board the ISS have resumed their regular work schedule, NASA reported in a status update.
Astronauts on the International Space Station (ISS) are having to deal with an air leak from a possible collision.
Gerst, along with U.S. astronaut Serena Auñón-Chancellor and Russian cosmonaut Sergei Prokopyev, are due to use the same Soyuz vehicle to return to Earth at the end of the year.
The astronauts are now working with engineers on the ground to assess whether a more robust fix is needed.
Three Americans, two Russians and a German are now on board the station.
"Once the patching is complete, additional leak checks will be performed", NASA said.
