A Russian Progress supply ship successfully docked with the International Space Station early Saturday but in an unlikely, presumed coincidence, another Progress, docked at a different port, suffered a sudden loss of coolant similar to an incident that disabled a Soyuz crew ship in December.

It was not immediately known if the Progress MS-21/82S spacecraft suffered a malfunction of some sort or if it might have been hit by space debris or a micrometeoroid, like the small particle that ruptured a coolant line on the Soyuz MS-22/68S crew ferry ship two months ago.

The Russian space agency Roscosmos revealed a “depressurization” event via the agency’s Telegram account, saying the space station’s seven-member crew was in no danger. But the post did not specify which system had been affected. NASA clarified that later in a brief conversation with astronaut Frank Rubio aboard the station.

“Hey Frank, just want to make sure we put it out in the open in terms of status for 82P,” mission control called. “You guys are probably already aware we had that TCS (thermal control system) coolant leak out to space this morning. The leak has stopped but at this point, we believe that it’s completely leaked out.
