The crew on board is not in any danger. NASA and its Russian partner Roscosmos will attempt to hunt down the origin of a very small leak on the International Space Station this weekend, one that's been causing air to discharge a little more quickly from the ISS for the last calendar year. Both crew members now on board the station will stay in the Russian segment of the ISS over the weekend, whereas NASA attempts to isolate the source of the leak in other areas of the spacecraft. NASA first detected it could have a flow on the channel way back in September of 2019. Air inside the station slowly leaks out of the ISS over time, but officials noticed the air appeared to be escaping in a marginally higher rate than normal. Ever since that time, the flow appears to have increased marginally. However, NASA has not had much time to investigate. Things have been pretty busy on the ISS since September, with astronauts conducting various spacewalks and new vehicles such as SpaceX's Crew
