Astronauts talk about the failure to fix the leak on the ISS

Astronauts said that the leak of air from the Russian module “Zvezda” of the International Space Station (ISS) could not be eliminated. This was reported by RIA Novosti, citing negotiations of astronauts with the Earth.

Russian cosmonaut Sergei Ryzhikov closed the hatch to the segment’s intermediate chamber, where the leak was detected, on Sunday night to check its tightness. After opening it again, however, it was discovered that the pressure in the compartment continued to drop, meaning that the leak persisted.

The previous leak on the ISS was detected on December 19. Then the situation was complicated by the fact that the oxygen supply to replenish the loss of air on the station was coming to an end.

In September, a leak was detected on the Zvezda module of the Russian segment of the ISS, which, according to Roscosmos, provided a total atmospheric pressure drop on the station of 1 millimeter of mercury column in eight hours. It took more than a month to find and fix it.

Later, a toilet, a vacuum cleaner and the Electron-VM oxygen production system broke down in the Russian segment.

Russian cosmonauts Sergei Ryzhikov and Sergei Kud-Sverchkov, American astronauts Kathleen Rubins, Michael Hopkins, Victor Glover and Shannon Walker, and Japanese cosmonaut Soichi Noguchi are now working on the ISS.
