NASA's astronauts aboard the International Space Station (ISS) were temporarily moved to a SpaceX Dragon spacecraft on Friday due to an air leak detected in the Zvezda service module. This precautionary measure was taken while Russian cosmonauts worked on repairs. NASA spokeswoman Bethany Stevens stated that the move was made 'out of an abundance of caution.' Roscosmos identified two potential leak sites during routine checks, with one being quickly sealed. The leak rate had increased from approximately 0.5 kg of air lost per day to nearly 1 kg, raising concerns about the module's integrity. Despite these issues, Roscosmos confirmed that the situation posed no danger to the crew or the ISS systems, and pressure levels remained stable. After initial repairs, NASA instructed its astronauts to return to normal operations aboard the ISS. The ISS, launched in 1998, is a collaborative effort involving five space agencies, with NASA and Roscosmos managing daily operations.
