Russia Suffers Second Coolant Leak In Two Months

On Saturday morning, during docking operations of the Progress 83 (MS-22) spacecraft at the International Space Station, teams in Moscow identified a coolant leak aboard the already docked Progress 62 (MS-21) spacecraft which arrived at the orbiting lab back in October.

This comes 2 months after a leak was found on the Soyuz MS-22 (Crew) spacecraft while preparing for a Russian EVA on December 15th. The leak triggered a joint investigation between NASA and Roscosmos to determine the cause of the leak - which the agencies both claim was a micrometeorite... but was it?

That result is looking less likely now with a second leak sprung in the same system, on a Progress resupply spacecraft.

In a statement from NASA to The Launch Pad.
