- Serious ISS air leak forces NASA astronauts to temporarily take shelter in Dragon capsule
A serious air leak in the Russian segment of the International Space Station (ISS) prompted NASA astronauts to temporarily shelter in the Dragon capsule as Roscosmos conducted repair operations. Leaks in the Zvezda module's transfer tunnel escalated in size, with partial repairs attempted using Germetall-1 sealant, though the issue remains unresolved.
- Nasa reverses evacuation alert order for astronauts aboard International Space Station
NASA reversed an evacuation order for astronauts aboard the International Space Station (ISS) after a worsening air leak prompted temporary sheltering in SpaceX Crew Dragon spacecraft. The agency and Russia’s Roscosmos examined the leak rate, with Roscosmos stating no immediate threat to the crew despite ongoing efforts to repair cracks in the Zvezda service module. This marked the first reversal of a safe-haven order in the ISS’s 27-year history.
- NASA directs its ISS crew members to board spacecraft amid leak repair attempt
NASA directed five astronauts to board a SpaceX Dragon spacecraft as Roscosmos attempts to repair leaks on the International Space Station's Zvezda service module. The leaks have raised concerns, prompting NASA to advise its crew to take an elevated safety posture during the repair operation.
- Uh-oh, the International Space Station is leaking again
NASA confirmed that the Russian segment of the International Space Station is leaking atmosphere again, reversing hopes that the problem had been resolved in January. Microscopic structural cracks in the PrK module, a transfer tunnel attached to the Zvezda Service Module, have been the persistent source of leaks that engineers from both Roscosmos and NASA have been tracking for over six years.
