NASA has confirmed that the Russian segment of the International Space Station (ISS) is experiencing another atmospheric leak. Engineers have been grappling with these leaks for over five years from a small Russian module known as the PrK tunnel.

The leak first returned three weeks ago, after reports indicated a ‘slow pressure drop’ in the PrK module by Russian cosmonauts. NASA spokesperson Josh Finch stated that teams are maintaining the area at lower pressure with occasional repressurizations. While there are no immediate risks to the astronauts or station operations, this has raised questions about the long-term viability of the ISS.

Historically, NASA officials have played down the severity of these leaks in public discussions but have acknowledged their potential for catastrophic failure within the agency’s risk matrix. This latest leak could signal a need for more robust maintenance and repair strategies as the ISS continues its operations beyond 2030.
