Uh-oh, the International Space Station is leaking again
Imagine being on the International Space Station when suddenly, NASA confirms the Russian segment is leaking atmosphere again. That's exactly what happened recently, and it's a problem scientists thought they'd fixed. For over five years, engineers from NASA and Roscosmos have been chasing tiny cracks in the PrK module — this transfer tunnel attached to the Russian Zvezda unit. According to Eric Berger writing for Technology, despite multiple inspections and sealant patches, the leak persisted. In January, NASA announced they’d stabilized the pressure inside that module, giving hope it was finally resolved. But now, the leaks are back, and it’s a reminder of how stubborn space problems can be. These microscopic cracks are tricky — they hide, they reappear, and they’re hard to pinpoint. As Berger reports, NASA’s been tracking this closely, knowing that even the smallest leak can be a big deal in the vacuum of space. So, the question is — what’s next? Expect more inspections, more fixes, and a lot of patience. That subtle shift in confidence could be the sign of a bigger puzzle still unfolding.
