MOSCOW, November 19. / TAX /. The crack in the previously insulated intermediate chamber of the Zvezda module remains, cosmonaut Sergei Ryzhikov told Mission Control.
Previously, the crew closed the hatches in the intermediate chamber. Mission Control asked if the crew measured the pressure before the hatch in that chamber was open. The crew reported that the pressure dropped markedly in the smaller part of the compartment while it remained isolated from the rest of the station by an airtight hatch.
“The pressure in the intermediate chamber dropped from 723mm of the mercury column to 685mm,” Ryzhikov said.
On Tuesday, the crew placed a new patch on the crack. Russian space company Roscosmos later told TASS that several measurements would be made with the aim of eventually identifying the cause of the leak.
On October 15, the ISS crew told Mission Control that the escape point had been provisionally found in the intermediate chamber of the Russian module Zvezda. Cosmonaut Anatoly Ivanishin later said that the possible crack looked like a curvilinear scratch 2-3 centimeters long. Cosmonauts later specified that the crack was about 4.5 centimeters long.
On Wednesday, during a spacewalk, the area of the suspected leak was photographed from the outside. Cosmonauts noticed no external damage in the crevice area.
