The International Space Station is experiencing renewed atmospheric leaks from the Russian PrK module, with NASA confirming a loss of about one pound of air per day. While the leak doesn't currently threaten crew safety or station operations, it revives concerns about persistent structural issues in the aging Russian segment that have been monitored for over five years. NASA and Roscosmos are coordinating on next steps while maintaining the affected area at lower pressure with periodic repressurizations.
Background
The International Space Station has been in continuous operation since 1998 and requires constant maintenance, with the Russian segment experiencing recurring air leaks in recent years. The PrK module, where the current leak is located, is a transfer tunnel connected to the Zvezda Service Module.
