The Russian Zvezda module of the International Space Station (ISS) recorded the continuation of air leakage after the sealing of two cracks. This was reported by RIA Novosti with reference to the negotiations of the cosmonauts with the Earth.
According to the agency, at about 10:00 Moscow time on March 13, cosmonaut Sergei Ryzhikov told a specialist at the Mission Control Center near Moscow that the pressure in the intermediate chamber of the Zvezda module was 678 millimeters of mercury. On Friday, at about 22:30 Moscow time, after closing the hatch into the compartment, it was 730 millimeters of mercury. In 11 and a half hours, the pressure in the chamber dropped by 52 millimeters.
On March 10, it was reported that a new crack was found on the ISS in the Zvezda module. Ryzhikov applied a second layer of sealant to a second crack located near the thermal management system pipeline. On January 16, NASA announced that the search for the second air leak in the Russian module was stopped until February, before the arrival of the next Progress spacecraft.
A hole in the ISS corps was formed at the end of December 2020. An air leak in the Russian module at the station was discovered in September.
