The crew of the International Space Station (ISS) has failed to fix the air leak in the Russian Zvezda by using adhesive tape in the module’s section, where a crack is supposedly located, as the pressure continues to decline, according to conversations between the ISS crew and Earth, broadcast by NASA.

On Thursday, the Moscow Mission Control Center instructed Russian cosmonaut Ivan Vagner to use as much tape as possible in Zvezda’s intermediate chamber, where the source of the leak is expected to be located.

On Friday morning, Vagner informed specialists at the Center that the pressure in the compartment had declined by 17 mm Hg down to 715 mm Hg.
