The United States space agency NASA placed astronauts aboard the International Space Station (ISS) on emergency standby after a persistent air leak in a Russian section of the orbiting laboratory showed signs of worsening, raising new concerns about the safety of the station and its crew.
According to NASA officials, astronauts were instructed to move into their docked spacecraft and prepare for a possible evacuation while engineers assessed a growing leak originating from Russia’s Zvezda service module. The precautionary measures were taken after monitoring systems detected an increase in the rate at which air was escaping from the station.
The affected area is located within the Russian segment of the ISS, specifically the Zvezda module, which serves as a critical component of the station’s life-support and habitation systems. Small air leaks have been detected in the module for several years, but recent data indicated that the situation may be deteriorating more rapidly than expected.
As a result, the four members of NASA’s Crew-12 mission were directed by mission controllers to enter the Crew Dragon spacecraft currently attached to the station and put on their spacesuits. The crew includes two American astronauts, one French astronaut, and one Russian cosmonaut. The move was intended as a precautionary safety measure should conditions worsen and a rapid departure from the station become necessary.
NASA stressed that the crew was not in immediate danger but said it was important to prepare for all possible scenarios. The astronauts remained on standby while engineers from both NASA and Russia’s Roscosmos space agency worked to evaluate the leak and determine whether repair efforts would be successful.
The incident highlights a long-running disagreement between NASA and Roscosmos regarding the source and severity of air leaks aboard the station. For months, specialists from both agencies have been investigating the issue, debating whether the leaks are the result of aging hardware, structural fatigue, microscopic cracks, or other causes.
The International Space Station, which has been continuously inhabited since 2000, is now entering the later stages of its operational life. As the station ages, maintenance challenges have become increasingly common, with engineers regularly monitoring its systems for signs of wear and deterioration.
According to a senior NASA official, the rate of air loss recently doubled, increasing from approximately one pound of air per day to two pounds per day. While that amount remains manageable for station operations, the sudden increase prompted heightened concern among mission managers and led to the decision to place the crew in a state of readiness.
Russian specialists have been working to locate the precise source of the leak and implement repairs. Similar incidents in previous years were addressed through sealing procedures and structural inspections, but officials continue to monitor whether the latest repair efforts will be sufficient to stop the worsening loss of air.
The situation underscores the delicate nature of operating a permanently crewed outpost in space, where even seemingly minor technical problems can quickly become serious concerns. With astronauts living more than 400 kilometers above Earth, emergency preparedness remains a fundamental part of station operations.
NASA and Roscosmos are expected to continue working together closely over the coming days as they assess the effectiveness of repair efforts and determine whether additional safety measures will be required.
For now, the crew remains safe aboard the ISS, but mission controllers are maintaining a heightened state of vigilance while the air leak investigation continues.
