On the ISS there was a depressurization in the spacecraft “Progress MS-21”

This happened after another cargo ship docked with the Zvezda module.
The depressurization of the Progress MS-21 cargo ship docked earlier to the Poisk module occurred half an hour after docking on Saturday to the Zvezda module of the new Progress MS-22 cargo ship.
According to an unofficial version, the air leak could have occurred as a result of vibration during the docking of a new cargo ship.
Recall that on December 15 last year, there was a depressurization of the external contour of the radiator of the thermal control system of the Soyuz MS-22 spacecraft. The Roscosmos Commission then came to the conclusion that the emergency occurred due to an external impact on the instrument-assembly compartment (PAO).
But I didn’t find out exactly what: the initial version with the meteorite disappeared, experts were more inclined to believe that there had been a collision with a fragment of space debris flying at a lower speed than meteors – this is evidenced by a very small diameter of the hole – less than 1 millimeter .
At 5:00 pm on February 11, an unscheduled meeting was scheduled at Roscosmos regarding a new incident. On February 18, the Progress MS-21 launch from orbit is scheduled.
The launch of the unmanned rescue ship Soyuz MS-23, which was supposed to fly to replace another depressurized ship on February 20, will most likely be postponed until the causes of a new leak are clarified.
