The Russian cargo Spacecraft known as Progress MS-21 suddenly depressurized while docked with the ISS. The incident took place during the early hours of Saturday. The Russian space agency reported that the depressurized section was quickly isolated. The seven crew members aboard the orbiting laboratory report that they feel fine. So far the cause is unknown and still under investigation. Impacts by small meteorites and even orbiting debris are not uncommon aboard the station, this is the likely cause of the incident. The Russian space agency added that the incident has not affected the docking of the Progress MS-22 cargo spacecraft. MS-21 is scheduled to re-enter Earth’s atmosphere on February 18, the spacecraft will mostly burn up during re-entry and what remains will land in the ocean.
