Tension Flared on Space Station as Russia Threatened to Drill and Saw Into Wall, Prompting NASA Astronauts to Take Shelter

Key Points:

• The International Space Station (ISS) has been experiencing persistent air leaks, particularly from the PrK tunnel section connecting the Russian Zvezda module to the aft docking port, with issues dating back to at least 2019.
• On June 5, 2024, NASA ordered five astronauts to take shelter in a docked Dragon spacecraft due to Russian attempts to repair cracks in the PrK module, highlighting tensions between NASA and Roscosmos over how to handle the leak.
• Disagreements escalated as Roscosmos considered using a handsaw and drilling to fix the leak, which NASA opposed, fearing damage to a load-bearing bracket; NASA's shelter-in-place directive reportedly led Roscosmos to halt their planned repairs.
• The PrK module is expected to be decommissioned and unpressurized, limiting the use of its attached docking port, though experts believe the ISS could continue operating without it despite potential risks.
• This incident underscores ongoing challenges in international cooperation on the ISS and raises concerns about the station's aging infrastructure and future safety measures.
