According to the Russian satellite network, at the end of last month, the International Space Station had an air leakage decompression accident. Upon investigation, the accident was caused by a perforation on the Russian spacecraft. At present, the "loophole" on the spacecraft has been filled. However, for this matter, the Russian astronauts on the International Space Station were worried.

It is reported that Russian astronaut Oleg Altemiev said recently that his colleague and astronaut Sergei Prokopiev had more than 40 hairs gray after the "air leak" accident of the Soyuz spacecraft.

In a video released by astronauts, Altemiev is cutting Prokopiev's hair. Altemiev said: "When you came to the space station, there were only four white hairs, but now, there are 47!" Prokopiev said that white hairs only came after the decompression accident of the spacecraft.

In the early morning of August 30, Moscow time, the attendant of the Russian Flight Control Center found that there was a slight air leak in the International Space Station cabin, and the pressure in the space station was reduced. After inspection, astronauts in the International Space Station found a hole with a diameter of about 1.5mm on the orbital bulkhead of the Soyuz spacecraft docked with the space station, and quickly repaired it with glue and tape.

The cause of the pinhole is still uncertain, but experts have ruled out the impact of space debris or small meteorites. According to the previous report, the internal investigation of the Russian Energy Rocket and Space Group showed that the perforation on the Soyuz spacecraft was "intentional", but no perpetrators were found.
