The International Space Station has a hole in it. Last week after noticing a drop in pressure inside the station, the official statement was that a meteorite had caused the hole.
Now the story has changed. Apparently, the hole was done with a drill, either accidentally or on purpose, either on Earth or in space.
As you can see in the picture, there are marks from a sliding drill, so they think that it could just have been a bungling technician who slipped and made the hole and glued it up without telling anyone, and now the epoxy has come lose.
At any rate, the astronauts have fixed it temporarily with epoxy, so they are safe for now. If they hadn’t caught it, they would have run out of air in 18 hours!
