NASA previously stated that in order to find the source of benzene, the air of the Russian-American cabin of the International Space Station has been cut off, and the Russian cabin is being measured using the AQM-1 instrument to determine the air quality.
NASA said: "AQM-1 made two measurements in the Russian cabin, and then the fuse was blown, and was forced to take it back to the US cabin for inspection and found an internal short circuit."
According to the news, due to the failure of the instrument to search for the source of benzene, the crew of the International Space Station has restored the air circulation between the Russian and American cabins.
The Russian National Aerospace Group revealed in May that the concentration of benzene in the air of the International Space Station has increased, but it has not exceeded the limit allowable value, and it poses no threat to personnel. The source of benzene has not been found so far.
Currently on the International Space Station are Russian astronauts Anatoly Ivanishin, Ivan Wagner, American astronauts Christopher Cassidy, Douglas Hurley, and Robert Benken.
