MOSCOW: A coolant leak from an uncrewed Russian supply ship docked at the International Space Station resulted from an external impact and not a manufacturing flaw, Russia's space corporation said on Tuesday .
Russian space officials said the earlier leak was caused by a tiny meteoroid that left a small hole in the exterior radiator and sent coolant spewing into space. But the new leak from another ship raised doubts about that theory, and Russia's state space corporation Roscosmos launched a probe into the incident to check whether it could have resulted from a manufacturing defect.
Following checks at Russian space factories and launch facilities and a close inspection of the cargo ship before it was dumped, Roscosmos concluded that the leak resulted from an “external impact” similar to the one that caused December's leak from the Soyuz crew capsule. On Tuesday. Roscosmos posted a close shot of the Progress MS-21 showing a 12-millimetre hole in its external radiator, which it said hadn't been spotted before.
