Can the leak at the International Space Station be catastrophic? NASA thinks so; here are the repercussions of it

'Catastrophic' is how NASA describes the potential for an international space station leak.

NASA is worried about the Russian module's structural integrity and the possibility of a catastrophic failure, according to Bob Cabana, chair of the ISS Advisory Committee.

Since 2019, there has been a continuous air leak on a Russian portion of the ISS, which has NASA increasingly concerned, as quoted in a report by the People.


Bob Cabana, a former NASA astronaut and current chair of the ISS Advisory Committee, brought up the matter at a meeting on Wednesday, Nov. 13, according to SpaceNews.

The Russian team does not think that a catastrophic disintegration of the PrK module is likely, even though they are still looking for and sealing the leaks.

NASA has voiced concerns regarding the PrK's structural soundness and the potential for a catastrophic failure, stated Cabana.

According to the news site, he went on, The Russians think that ongoing operations are safe, but they can't prove that to them, and the U.S. thinks that it's not safe, but they can't prove to the Russians that that's the case.

Although the exact cause of the leaks is still unknown, the ISS and Russia's space agency, Roscosmos, have narrowed their focus to internal and external welds, according to a September report from NASA's Office of Inspector General.

According to the report, the news follows NASA's discovery of a rise in the leak rate in February. Repairs decreased the air leak rate "by roughly a third" from its peak of 3.7 pounds per day in April.

The ISS Program and Roscosmos formally convened in May and June to address elevated concerns, thereby elevating the leak risk to the highest level within its risk management system, according to the report.

NASA says Roscosmos is certain they can keep an eye on the Service Module and seal the hatch before the rate of leaks becomes unmanageable. The report went on to say that NASA and Roscosmos have not agreed on the point at which the leak rate is untenable.

FAQs

Why is NASA concerned about the air leak on the ISS?
NASA is concerned that the air leak in the Russian module will cause structural issues and potentially catastrophic failure. While repairs have reduced the leak rate, the underlying cause remains unknown.

Is the International Space Station still safe for astronauts?
Despite the leak, Roscosmos believes that operations can continue as usual. However, NASA remains cautious and insists on ongoing monitoring and repairs to ensure astronaut safety, as no definitive agreement on risk levels has been reached.
