Another Russian vehicle at the International Space Station has suffered a coolant leak. Flight controllers noticed Monday afternoon flakes coming from a radiator on the Nauka module on the station's Russian segment, and astronauts on the station confirmed that the flakes were coolant leaking from that radiator. Roscosmos said the leak was from a backup radiator that had been on the station since 2010 but only recently moved to the Nauka module. The leak did not jeopardize the station or its crew, both Roscosmos and NASA concluded. A Soyuz spacecraft experienced a coolant leak last December that forced Roscosmos to replace the spacecraft, while a Progress cargo spacecraft also had a coolant leak in February.
