The crew of the International Space Station announced a sharp decrease in pressure in the Russian unit “Zvezda”. The crew reported that the pressure had dropped to 154 mm Hg.

For comparison, last spring, when the problem of air leakage in the transitional chamber was eliminated, the pressure was at a level of 405 mm Hg.

In September 2019, a small air leak was recorded at the International Terminal. After increasing the speed of this leak fivefold, in August-September 2020, the crew closed the hatches in the space station modules twice to check their isolation and the Russian section was isolated for several days. And it turned out that the leak was in the transitional cabin of the Russian unit “Zvezda”.

Last October, cosmonauts Anatoly Ivanchin and Ivan Wagner discovered, when using tea leaves, a crack of 4.5 cm in length. The incision was temporarily stretched with heat-resistant tape, and then patched with a flexible disc made of rubber and aluminum foil. But all this did not allow to completely get rid of air leakage.

And at the beginning of this year, Vladimir Solovyev, director of flights for the Russian C-section of the station, indicated that due to the leak, which is equivalent to a hole with a diameter of 0.2 mm, the air pressure at the station drops by 0.4 mm of mercury per day, a figure far from emergency values ​​- starting from 0.5 mm per minute. To make up for the leak, air, nitrogen and oxygen must be regularly pumped into the International Space Station. The reserves of these gases are available at the station and are transported from the ground on cargo ships.
