Great use of small notes! Astronauts use paper to find air leaks in the space station

　　China News Service, March 16th. According to a report from the Russian Satellite Network on the 16th, the astronauts broadcast by the National Aeronautics and Space Administration (NASA) showed that the crew of the International Space Station is using a small note to help find the Russian "Star" cabin Air leak point.

　　Previously, the crew sealed two cracks in the transfer compartment of the "Star" cabin, but despite this, the pressure in the cabin continued to decrease.

On January 27, local time, NASA astronaut Mike Hopkins was working outside the European Laboratory of the International Space Station.

　　On the evening of March 15, experts from the Moscow State Flight Control Center asked the astronaut Sergey Ryzhkov to install two GoPro cameras in the "leak" cabin and toss 40-50 pieces of less than one centimeter in size. A note, and then close the door leading to the transit compartment.

　　The expert's idea is that due to an air leak in the cabin, the paper tape will move to the leaking point, and the camera will record the position of its movement.

　　In September 2019, a small amount of air leakage was detected on the International Space Station.

In October 2020, the crew found a crack in the transit compartment of the Russian cabin Star.

Later, a second crack was discovered.

Both leaks were blocked in March 2021.

　　The Russian Aerospace Corporation previously pointed out that the air leak does not pose a danger to the International Space Station and the investigation team.

Prior to this, the air pressure of the International Space Station dropped at a rate of up to 0.4 mm Hg per day, which is far less than the accident value of 0.5 mm Hg per minute.

The International Space Station has air, oxygen, and nitrogen reserves that can be used to maintain atmospheric pressure, and the cargo spacecraft will also deliver the required gas on time.

　　The current members of the International Space Station expedition team include Russian astronauts Sergey Ryzhkov and Sergey Kudy-Sverchikov, and American astronauts Catherine Rubens, Michael Hopkins, and Victor Glover and Shannon Walker, and Japanese astronaut Soichi Noguchi.
