Russia appears set to finally address long-term, serious space station cracks

In a dramatic turn of events aboard the International Space Station (ISS), NASA recently instructed its astronauts to take refuge in a Crew Dragon spacecraft due to safety concerns. This precautionary measure was taken in light of ongoing issues with cracks in the Russian Zvezda service module, specifically in the PrK module. Reports indicate that the cracks have been a persistent problem since 2019, with Russian astronauts employing various methods to address the leaks, including the use of a sealant known as Germetall-1. Earlier this year, it was believed that the situation had improved when Roscosmos, Russia's space agency, announced that the leaks had stabilized. However, renewed leaks began in May, escalating in early June. In response, Roscosmos initiated a comprehensive inspection and repair plan on June 5. Although the agency did not release detailed information about the situation, the proposed solutions raised alarms for NASA, leading them to temporarily secure their astronauts in the Crew Dragon as a safety measure against potential depressurization. Fortunately, after further analysis and discussions, Russian officials decided to conduct additional measurements and inspections, which eased NASA's concerns. The U.S. space agency expressed support for this cautious approach, allowing their astronauts to return to normal operations aboard the ISS. This incident underscores the ongoing challenges faced in maintaining the aging infrastructure of the space station and the importance of international cooperation in resolving these critical safety issues.
