It failed, the pressure in the “leaky” compartment continues to fall
The crew of the International Space Station (ISS) tried to eliminate the air leak in the docking station by sealing it with tape. However, this was not done.
According to RIA Novosti, the pressure in the compartment continues to decrease. On the morning of Friday, October 9, Russian cosmonaut Ivan Wagner opened a hatch in the “leaky” one and reported to the Mission Control Center that the pressure in it was 715 millimeters of mercury. It was 732 millimeters before closing the hatch yesterday. The rate of pressure drop on the ISS is one millimeter of mercury in eight hours. The state corporation Roscosmos assured that this does not pose a danger to the ISS crew and does not interfere with the station’s flight in manned mode.
For his part, Vladimir Soloviev, Flight Director of the ISS Russian Segment, told the crew that the air leak was “insanely small” and that it was “that is, it is not.” According to him, air can escape through a hole or crack 0.6-0.8 mm in size. As Soloviev noted, it may not be found.
On the eve of the MCC, Wagner was asked to “seal the area of the docking station with tape as much as possible.”
A leak was found in the intermediate chamber of the Zvezda module. There is the ISS docking station.
At the end of August 2018, an air leak occurred on the International Space Station. The cosmonauts checked all the compartments and found a microcrack in the living compartment of the Russian Soyuz MS-09 spacecraft. The cosmonauts closed the hole with a special sealant. Different versions have been put forward regarding the reasons for the hole. According to one of them, it could have been done by astronauts from the US National Aerospace Agency (NASA) in order to deliver one of their sick colleagues to Earth as soon as possible. It was also believed that it was drilled by one of the “mentally unstable astronauts. ”
