  1. Roscosmos Considers Permanently Sealing Leaky PrK Module

    Roscosmos may decommission the PrK module to stop a persistent air leak. This leak has affected the station since 2019. Recent repair efforts involved high-risk drilling operations.

    What's confirmed:

    • The PrK module has had a persistent air leak since 2019.
    • NASA sheltered 5 astronauts in a Dragon capsule on June 5 while Roscosmos planned to drill into a leaking module.

    Still unconfirmed:

    • Roscosmos is planning to decommission the PrK module.
    • Russia may seal the leaking module.
    confidence 80%

  2. Russia May Abandon Leaky ISS Module After Failed Repairs

    NASA and Roscosmos are managing air leaks that have persisted for seven years. Recent high-risk repair attempts forced astronauts into emergency shelters. Russia's deteriorating modules are accelerating its withdrawal from the station.

    What's confirmed:

    • Air leaks in the International Space Station have existed for seven years.
    • NASA and Roscosmos are working on a collaborative approach to address the leaks.

    Still unconfirmed:

    • Russia's withdrawal from the ISS is accelerating due to worsening leaks in aging modules.
    confidence 80%

  3. Russia Considers Abandoning Leaky ISS Module Amid NASA Dispute

    Russia may permanently seal the leaking PrK tunnel to reduce air loss. This follows a period of tension between NASA and Roscosmos over repair strategies. Astronauts were briefly evacuated as repair efforts were attempted and then halted.

    What's confirmed:

    • The International Space Station has experienced air leaks first detected in 2019.
    • NASA and Roscosmos have disagreed over how to address the station cracks.
    • Astronauts were temporarily moved to a safe haven during repair attempts.
    • Repair efforts were halted and crew members have since returned to the station.
    • Roscosmos recently abandoned a plan to cut into a section of the space station.

    Still unconfirmed:

    • Air is leaking from the Russian module at a rate of about one pound per day.
