Russian cosmonauts, with the participation of their American colleagues, closed up three more potential air leaks on the International Space Station.

The sealant and new patches have not yet helped the astronauts to repair the station's hull.

According to TASS, three potential air leakage sites were repaired by Russian and American crew members at the International Space Station. According to David West, spokesman for NASA's aerospace safety advisory board, who spoke online at the July 15 meeting, the patches and sealant were applied in three places, but the leak rate never completely decreased.

West noted that there is no risk to the safety of the crew, but the advisory board still wants to keep abreast of what is happening on the ISS. In March of this year, cosmonauts Sergei Ryzhikov and Sergei Kud-Sverchkov carried out a complex of repair and restoration work on the Zvezda module hull, where a crack and a number of possible leaks had been discovered earlier.

The Russian crew members performed all the manipulations under the leadership of the ISS Russian Segment Main Operational Group and RSC Energia engineers, in addition, all work was coordinated with NASA specialists. In mid-April, cosmonaut Ivan Wagner told reporters that the air leak after sealing the cracks decreased three times. To compensate for the leak, the ISS regularly needs to be pressurized with air, nitrogen and oxygen, the reserves of which are both at the station and are regularly transported by cargo ships from Earth.

The 65th expedition is currently working at the station, consisting of the Russians Oleg Novitsky and Peter Dubrov, the Americans Mark Vande Hai, Shane Kimbrow and Megan MacArthur, the Frenchman Thomas Peske and the commander of the station, the Japanese Akihiko Hoshide.
