MOSCOW, November 19 / TASS /. The crack in the previously isolated intermediate chamber of the Zvezda module remains, cosmonaut Sergei Ryzhikov told the Control Mission.
Earlier, the crew locked the hatches in the intermediate chamber. Mission control asked if the crew measured the pressure before opening the hatch in that chamber. The crew reported that the pressure dropped significantly in a smaller part of the compartment, while it remained isolated from the rest of the station by an airtight cover.
“The pressure in the interstitial chamber decreased from 723 mm of mercury to 685 millimeters,” Ryzhikov said.
On Tuesday, the crew placed a new patch over the crack. The Russian space corporation Roscosmos later told TASS that several measurements would be made with the aim of finally determining the cause of the leak.
On October 15, the ISS crew told the Control Mission that the leak was tentatively found in the intermediate chamber of the Russian Zvezda module. Cosmonaut Anatoly Ivanishin later said that the possible crack looked like a curved scratch 2-3 centimeters long. The astronauts later specified that the crack was about 4.5 centimeters long.
During a spacewalk on Wednesday, an area of suspected leakage was photographed from the outside. The astronauts did not notice any external damage in the crack area.
