International space station air leakage, all doors will be closed investigation

On the 20th local time, the National Aeronautics and Space Administration of the United States (NASA) announced on its blog that the air leakage level of the international space station has risen, and the three astronauts inside the station have temporarily entered Russia's area to evade. Ground managers are stepping up to confirm solutions. Sewage pump

According to the US "business insider" website, the US and Russian space administrations said that the US and Russian space departments "are working out a revised plan to isolate, confirm and repair the source of the leak", but the leakage level is still within the standard range and "will not endanger the astronauts and the space station". Russian satellite news agency support sources said the source of the leak may be in the U.S. division of the space station. Russia's new company also announced that in order to identify the problem, astronauts and ground control plan to close all doors and continuously monitor the pressure of each cabin. Magnetic pump

According to NASA, a preliminary investigation report is expected to be completed by the end of next week to determine the exact location of the gas leak. One American astronaut and two Russian astronauts from the space station spent the weekend in the star service module in Russia. The Soyuz, which can bring three people back to earth in an emergency, docked with a small laboratory near the service module. Chemical pump

According to "business insider", the service room of the "Star" was launched nearly 20 years ago, because it is the first habitable room of the international space station, in which three astronauts have enough space to move. It is reported that the last time the international space station reported an air leak was in 2018. At that time, the Soyuz made a hole in the bulkhead, and Russian astronauts found the source of the leak through the space flight checkpoint and repaired it with epoxy resin. Self priming pump
