NASA said the leak would not pose a risk to astronauts on the international space station. Modules of the international space station will be blocked, and NASA will measure the pressure in each area to determine the source of the leak. < / P > < p > as NASA explained in a new blog post, astronauts on the international space station recently discovered an unexpected leak, but they are not sure which area of the large laboratory it is located in. So, to help narrow down, the ISS is entering a lock-in mode, with astronauts isolated to one part of the ISS while the other modules are sealed off. < / P > < p > NASA said it would not pose a risk to astronauts, but they would have to check when an increase in air leakage was detected. The easiest way to know which area of the space station is leaking is to separate them and monitor the atmospheric pressure in each area. “By the end of the week, all station doors will be closed, so mission controllers can carefully monitor the air pressure of each module,” NASA explained. “This test will not bring safety issues to the crew. This test should determine which module has a higher than normal leak rate. ” < / P > < p > this is not the first time an accidental air leak has occurred on the international space station. About two years ago, there was a leak on the international space station. The leak was found to be due to a crack in the Soyuz spacecraft attached to the international space station. The crack existed before the spacecraft set off for earth, but was sealed with adhesive. < / P > < p > the Russian space agency has launched an investigation into how the crack occurred and how it was missed during the inspection of the spacecraft by inspectors before launch. The Russian space agency said it had found out what had happened, but had not released details. Global Tech
