NASA and its Russian partner Roscosmos are going to try to hunt down the source of a very small leak on the International Space Station this weekend, one that has been causing air to release a little more rapidly from the ISS for the last year. The three crew members currently on board the station will stay in the Russian segment of the ISS over the weekend, while NASA tries to isolate the origin of the leak in other parts of the spacecraft.
NASA first noticed it might have a leak on the station way back in September of 2019. Air inside the station slowly leaks out of the ISS over time, but officials noticed that the air seemed to be escaping at a slightly higher rate than usual. Since then, the leak seems to have increased slightly….tech, The Verge
