Uh-oh, the International Space Station is leaking again
This further confirms the wisdom of the current policy of retiring the ISS in 2030.
TL;DR
- The Russian segment of the ISS is experiencing another atmospheric leak.
- The leaks originate from microscopic structural cracks in the PrK module.
- NASA had previously announced a stable configuration for the PrK module in January.
- A slow pressure drop was noted on May 1, indicating the leak has returned.
- The leak rate is approximately one pound per day, and the affected area is being maintained at a lower pressure.
- The issue is classified internally by NASA as a high-likelihood, high-consequence risk with potential for catastrophic failure.
- Roscosmos has managed the leak in the past by closing the hatch to the PrK module.
- NASA is considering extending the ISS lifespan to at least 2032, but the reemerging cracks question this strategy.
- Extending the ISS requires international partner support, including from Russia.
- NASA is pursuing commercial space stations as replacements, but companies are concerned about lifespan extensions delaying their readiness.
- Some former NASA officials believe retiring the ISS in 2030 and focusing on commercial platforms is the best approach.
