CNN —The Russian space agency, Roscosmos, is searching for answers after one of its modules on the International Space Station sprang a coolant leak, adding to the list of mechanical issues the space agency has grappled with in low-Earth orbit over the past year. Roscosmos said Monday in a notice posted to the messaging site Telegram that the coolant leak affected a radiator circuit on the Nauka module, which is located on the Russian-controlled segment of the ISS. The Nauka module was added to the space station in July 2021, but the leak occurred on an external, backup radiator that was delivered to the ISS on a space shuttle mission in 2010, according to NASA. ‘External influences’ and space troubleThe Russian space agency has already spent nearly a year working to get its crew transportation missions back on track after one of its Soyuz spacecraft experienced a noteworthy coolant leak in late 2022 while it was attached to the space station. Roscosmos determined that the coolant leak on the Soyuz spacecraft had rendered the vehicle unsafe and decided to launch a replacement capsule to bring the crew home.
