Another Russian module develops leak on ISS
For the third time in less than a year, a Russian spacecraft at ISS has developed a coolant leak, this time in Russia’s newest module to ISS, Nauka.
The Nauka radiator actually has been in space for over a decade waiting for Nauka to arrive so whether there is any commonality to the failures is difficult to assess. Roscosmos acknowledged the leak, but said the module itself is working fine and there is no cause for concern.
The previous two leaks were on a Progress freighter, and later on a Soyuz capsule. Though Nauka was only launched to ISS in 2021, its development began in the 1990s and was originally scheduled for launch in the early 2000s. Because of the delays this radiator was launched to ISS ahead of the module, in 2012. It sits outside the module where it can release its excess heat into space.
The Russians say that the leak is in a backup coolant system, but according to a statement by Anatoli Zak quoted at the link, this statement is too vague. At the moment the location of the leak remains unknown.
