Astronauts fixed a hole in the International Space Station (ISS). Scientists usually do scientific experiments on the ISS. Last week, NASA said the station was slowly leaking air. An astronaut found the hole. He used a simple and quick way of doing this. He put his finger over the hole. Luckily, it was only two millimeters wide.
A small piece of space junk may have hit the ISS, which travels at around 28,000 kph. Flight controllers in the USA and Russia helped the crew. A cosmonaut used a "space tape" and a special glue from a "space repair kit". NASA said: "The crew are healthy and safe with weeks of air left in the International Space Station reserves."
