Russia is investigating the possibility that the leaks on the Soyuz MS-22 and Progress-82 spacecraft were caused by errors in the manufacturing process.
It is possible that an error in the manufacturing process is behind the leaks observed in the Progress and Soyuz spacecraft. The information was released by Joel Montalbano, program manager of International Space Station TO NASAwho stated during a conference held on Saturday (11) that Russia is investigating this possibility.

In December, the Russian Soyuz MS-22 spacecraft, carrying three astronauts to the orbital laboratory, lost all of its refrigerant compound; the country’s officials attributed the event to the probable impact of a micrometeoroid. In February the a the cargo ship Progress-82 had a leak similar to that of the Soyuz.
Also that month, Russia’s Roscosmos space agency released the first images of the source of the Soyuz MS-22 leak:

According to Montalbano, the sequence of accidents led Roscosmos, Russia’s space agency, to investigate the country’s spacecraft manufacturing processes with Energia, a contractor in Russia’s manned spaceflight program. “Is there something there? Has anything changed in the manufacturing process of these vehicles?” he added. “That’s exactly what we would do. You look at all the data you have and all you can.”
Since Roscosmos believed that, unless an emergency occurred, the Soyuz MS-22 spacecraft could not return astronaut Frank Rubio and cosmonauts Sergey Prokopyev and Dmitry Petelin to Earth, it was necessary to send the Soyuz MS-23 spacecraft to the station. Montalbano said NASA is confident of the new vehicle, but that it is monitoring its situation in case of new events.
Originally, Rubio, Prokopyev and Petelin were to return to Earth in March, but due to leaks, they have to remain aboard the station until September, to return on Soyuz MS-23. The Soyuz MS-22 ship is expected to return by the end of the month, with no crew on board.
Moltabano stressed that, during re-entry into the Earth’s atmosphere, the spacecraft will eventually break up, so it will not be possible to examine the damaged area responsible for the loss: this is what happened to Progress, which left the orbital laboratory in February and which , having a structure designed to resist re-entry, ended up burning.
