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 February 21. The leak from the Progress MS-21 cargo ship was spotted on February 2 and followed a similar leak from a Soyuz crew capsule in December. Russian space officials said that the earlier leak was caused by a tiny meteoroid, but the new leak from another ship raised doubts about that theory. NASA said its specialists were assisting their Russian counterparts in the troubleshooting of the leak.
