The air at the International Space Station will be replenished with nitrogen on Wednesday to compensate for an air leak that was caused by a crack in Russia’s Zvezda module. This became known on March 3 from the negotiations of the crew with the Earth, broadcast by NASA.

“Today you will be pressurizing nitrogen up to 736 millimeters (mercury column – Ed.),” A mission control specialist told the cosmonauts.

On March 1, it became known that glue made from the resin of North African trees would be used to seal the crack in the Russian Zvezda module. Cosmonaut Sergei Ryzhikov will use Hermetall and Anaterm sealants, as well as glue-mastic, foam rubber, fluoroplastic films, metal linings and electrical tape. A drill and a sandpaper will be involved in the work.

On February 25, it became known that the ISS crew temporarily closed up a possible crack in the Russian Zvezda module, from where the air is likely to be leaking.

For the first time, astronauts found a 4.5 cm long crack back in October 2020. The hole was temporarily sealed with tape and then a patch. On February 24, 2021, the crew repaired the area of ​​the second possible crack.
