NASA Addresses Air Leak on International Space Station

For several years, the International Space Station (ISS) has dealt with ongoing air leaks in its Russian segment, specifically within the PrK transfer tunnel of the Zvezda Service Module.
These leaks, likely caused by microscopic cracks, have been a recurring maintenance challenge since 2019.
When Roscosmos began an invasive repair involving cutting a structural bracket, NASA ordered five astronauts to shelter in their Crew Dragon spacecraft as a safety precaution.
Although this created headlines about station safety, the mission was soon cleared to resume normal activities after Roscosmos paused the work for further assessment.
These incidents highlight the reality of aging infrastructure on the ISS, which is slated for retirement in 2030.
Despite differences in perspective, NASA and Roscosmos continue to coordinate closely.
Both space agencies emphasize that these leaks, while requiring constant monitoring and periodic repressurization, do not currently pose an immediate danger to the crew or the station's ongoing integrity.
