An uncrewed Russian cargo spacecraft docked at the International Space Station on Saturday has leaked coolant, but the incident does not pose any danger to the station’s crew, according to Russia’s space agency and NASA.

The hatches between the station and the Progress MS-21 were temporarily locked so the incident didn’t affect the orbiting outpost.
“The temperature regime and pressure on board the ISS are normal, nothing threatens the life and health of the crew and they feel fine,” Roscosmos said….
