It was found in the most recent Soyuz capsule, which is one of two docked at the space station and is home to three Americans, two Russians and a German.
On Wednesday August 29, at around 7pm East Coast time (midnight United Kingdom time), ISS flight controllers were alerted to a pressure leak in the space station.
Astronauts have scrambled to patch a tiny hole that was allowing air to leak from the Russian side of the International Space Station.
Thursday morning, the crew taped over the hole, slowing the leak.
The hole is located in the upper section of the Soyuz, which does not return to Earth, according to NASA.
Officials from Houston and Moscow will continue to monitor the situation as the crew works through its troubleshooting procedures.
After some debate, Russian controllers agreed with NASA's team to take more time to investigate the leak.
The astronauts now onboard the ISS are NASA astronuats Drew Feustel, Serena Auñón-Chancellor and Ricky Arnold, ESA astronaut Alexander Gerst and Russian astronauts Sergei Prokopyev and Oleg Artemyev.
The meteorite obviously wasn't large, and the crew was never in any real danger - unless you consider the fact that they'r orbiting Earth in a flimsy laboratory and being pelted by space rocks "dangerous" - but it's obviously a problem that requires immediate attention. The space station is heated and pressurized with an air mixture so that the astronauts can breathe normally, and it requires an airtight seal to ensure that the air can be continuously recycled.
