The six astronauts aboard the International Space Station are working to fix a leak in the wall of the International Space Station.
The problem was first detected by mission control Wednesday night as a reduction of pressure in the station, but it was small enough that the crew was allowed to sleep all night, NASA reported.
On Thursday morning, an investigation showed the hole was about two millimetres in diameter and appeared to be on the Russian side of the space station, in the module where the Soyuz spacecraft is docked, reported space enthusiasts listening online to the ISS livestream. The hole was likely caused by a micrometeorite or orbital debris hitting the space station.
European Space Agency astronaut Alexander Gerst reportedly put his finger over the hole initially.
