NASA finally tracks down persistent air leak on ISS, but it's not fixed yet - CNET

NASA and the ISS crew have been bothered by an air leak first noticed in late 2019.

The space agency emphasized that the leak poses no immediate danger to the crew.

Flight controllers woke up the astronaut and cosmonauts late on Monday night to have them troubleshoot the leak "that appeared to grow in size." The crew used an ultrasound leak detector to collect data for analysis.

The leak may be more consistent than it first appeared.

Isolating the leak to a particular service module is a big step.
