Uh-oh, the International Space Station is leaking again

NASA says the Russian side of the ISS is leaking atmosphere again from the PrK transfer tunnel.

Roscosmos detected a pressure drop of about one pound per day after a short period of stability.

NASA and Roscosmos are coordinating monitoring and next steps for the station.

The leak is not causing immediate operational issues, but repeated pressure-loss events raise long-term reliability concerns.
