NASA Triggers Emergency Protocols Over Escalating ISS Air Leak

The crew of the Crew-12 mission—comprising two U.S. astronauts, one French astronaut, and one Russian cosmonaut—received instructions to enter their spacecraft as a precautionary measure against the worsening pressure loss. While the Zvezda module has suffered from minor leaks for an extended period, the rate of depletion doubled on Monday, shifting from one pound to two pounds per diem according to senior NASA officials.

NASA and Roscosmos remain locked in ongoing discussions regarding the structural integrity of the module. Despite the immediate mobilization of the crew, the agency continues to evaluate the threat level of the breach while coordinating with Russian counterparts to stabilize the environment inside the orbiting laboratory.
