- Persistent leaks in the International Space Station's PrK module have stopped.
- The leaks were caused by microscopic cracks in the Russian segment's PrK module.
- The leakage rate doubled in 2024, raising concerns for NASA and Roscosmos.
- NASA confirmed the module's pressure is now stable after inspections and sealing.
- Russian cosmonauts used a patented sealant, Germetall-1, to fix the cracks over years.
- The process involved periodic hatch closures and dust accumulation checks to locate leaks.
