On December 31, 2021, the Russian State Space Corporation Information Agency announced that two Russian astronauts in orbit had discovered the last leak point of the Service Module of the International Space Station 'Zvezda' and had the capacity to repair it, and the tools and equipment required would be transported to the space station via the next "Progress" cargo spacecraft, after which the astronauts would begin to finally repair the leak.
According to an investigation by the Russian National Space Corporation, the air leak accident was deliberately committed by an American astronaut in order to cause the accident so that he could return to Earth as soon as possible.
