Andre jonin, a communications academician of the Russian Academy of Aerospace Sciences, said that the “small holes” on the surface of the international space station made people doubt the possibility of extending its service life beyond 2024. “If the technical conditions of the space station were normal, it could have been extended,” Andre jonin said. Now, problems related to long-term use are beginning to appear, not some large components of the space station, but small problems. People who own cars are familiar with this situation. It’s called falling apart. ” According to jonin, the current cracks will be found, controlled and repaired, but new problems may arise after that, which means that it is groundless to expect the international space station to operate without faults. “Anyway, in principle, it’s clear that we need to prepare for the fact that the space station will no longer exist after 2024.” < / P > < p > the international space station has been built since 1998, and will be put into full use after its completion in 2010. It is initially planned to be used until 2015, then extended to 2020, and then extended to 2024 again. At present, the participating countries are considering the possibility of extending the operation of the international space station to 2028-2030. < / P > < p > in September 2019, a small amount of air leakage was found on the international space station. Between August and September 2020, astronauts found that the leak rate increased fivefold (from 270 grams per day to 1.4 kilograms). To this end, the astronauts closed the door of each cabin twice to check its tightness. It was later found that the leak was located in the Russian “Star” service module. < / P > < p > Vladimir soloviyov, an expert of Russian aerospace group and the flight director of the Russian section of the international space station, said that the air leakage is very small and there is no time at any time, and the pressure loss rate of the international space station is 1 mmHg every 8 hours. A small amount of air leakage is not dangerous to the astronauts of the international space station, nor does it affect the flight of the station in manned state. According to Sergei krikaliov, executive director of the Russian Aerospace Group’s manned space program, more air needs to be delivered to the space station if the team members are unable to eliminate the leakage for a long time. Currently, Russian astronauts Anatoly Ivanisin, Ivan Wagner and American astronaut Christopher Cassidy are working on the international space station.
