NASA has reported that a coolant leak on a Russian module of the International Space Station (ISS) has been successfully contained after two days of investigation. The leak, which was discovered on Monday, caused the postponement of two scheduled spacewalks as engineers worked to determine the source and severity of the issue.
Fortunately, the astronauts on board the ISS were never in any immediate danger due to the leak. Toxic ammonia flakes were initially spotted on the Russian Nauka Multipurpose Laboratory Module, prompting astronaut Jasmin Moghbeli to confirm the backup radiator leak by observing it through the station’s windows.
According to NASA officials, the leak had no negative impact on the crew or the operations of the space station. They confirmed that the primary radiator for Nauka is still functioning normally. Despite this reassurance, concerns have been raised as this incident marks the third coolant leak on Russian equipment in recent months.
Experts are suggesting that there may be a systemic issue with the coolant systems, given the recurring leaks. In fact, this latest incident is part of a series of coolant escapes from Russian equipment on the ISS. Roscosmos, the Russian space agency, has previously attributed these leaks to micrometeroid impacts.
It is crucial to note that tensions between Russia and other ISS partners have escalated in light of Russia’s invasion of Ukraine. However, NASA officials have emphasized that ISS operations are continuing as usual, and there have been no reported interruptions to ongoing research and experiments.
NASA engineers will continue their investigation into the coolant leak to determine the root cause and implement necessary measures to prevent future incidents. Preserving the safety and functionality of the ISS remains a top priority for all parties involved in the joint international space endeavor.
