A major leak from a Russian capsule docked on the International Space Station was most probably caused when a small meteoroid smashed into a radiator, leading to coolant being sprayed into space, a Roscosmos official has said.
Sergei Krikalev, a former cosmonaut who is now director of crewed space flight programs at Russia’s space corporation, said Thursday’s leak from the Soyuz MS-22 could affect the capsule’s overall coolant system but that there was “no threat for the crew” of the space station.
