It was later revealed that there may have been at least six cracks in the Svesta intermediate chamber.
Due to the leak, it resembles a hole with a diameter of 0.2 mm, the air pressure at the station drops by 0.4 mm of mercury per day, but it is far from the emergency values - from 0.5 mm at. The ISS must be constantly pressurized with air, nitrogen and oxygen to compensate for the leak. Their products are available at ISS and they are transported by cargo from Earth.
