Radiator leak from Russian ISS module leaves spacewalkers cooling their heels
 

Russia's Soyuz MS-22 spacecraft, currently docked at the International Space Station (ISS), began leaking coolant Wednesday evening. According to Russia’s space agency Roscosmos, the instrument and assembly compartment’s outer skin was damaged. Fortunately, the crew is safe, and they conducted normal operations afterward. NASA said in a blog post that “the external radiator cooling loop of the Soyuz is the suspected leak source.”
