Air leakage in the intermediate chamber of the Zvezda module of the Russian segment of the International Space Station (ISS) was reduced by three times after sealing. Roscosmos cosmonaut Ivan Wagner told about this on April 15.
According to him, he and Anatoly Ivanishin discovered one crack. “Sergei Ryzhikov and Sergei Kud-Sverchkov found the second crack. The earth has prepared everything technically, they are now filling up these cracks, “- said the cosonaut during his visit to St. Petersburg” UEC-Klimov “.
There are still very small cracks, he added, but the air leak has decreased threefold. Before that, it was not high, since it was compensated by the life support of the station.
In early April, it was reported that Russian cosmonaut Sergei Ryzhikov continues to seal cracks on the ISS, using a sealant. With the help of a paste-like composition, the cosmonaut carries out the corresponding work on the repair of the pipeline and the welded seams of the module.
An air leak on the ISS was discovered in September 2020. To search for the leak, the crew of the Soyuz MS-17 spacecraft, which launched to the ISS on October 14, took equipment with them.
On August 30, 2018, an air leak also occurred on the International Space Station (ISS). A hole about 3 cm long was found in the manned compartment of the docked Soyuz MS-09 spacecraft. Experts are sure that the hole was made with a drill. The versions of damage to the ship both on Earth and in space were considered.
On January 11, it became known that after the incident with a hole in the skin, RSC Energia introduced a video surveillance system for the assembly of Soyuz spacecraft at all stages, and not only in the main areas.
