ISS looking for air leak again

(ORDO NEWS) — Russian cosmonaut Sergey Ryzhikov, aboard the International Space Station (ISS), is making measurements with an American leak detector in the Russian Zvezda module, in which a crack was discovered that caused an air leak.

According to RIA Novosti, this follows from the crew’s negotiations with the Earth, broadcast by NASA.

For the first time, an air leak from the ISS was detected in September 2019.

After the rate of atmospheric leakage increased fivefold, in August-September 2020, the cosmonauts and astronauts twice closed the hatches in the ISS modules to check their tightness.

In September 2020, it turned out that the leak was located in the intermediate chamber of the Russian Zvezda module – a crack 4.5 centimeters long. It was temporarily sealed with heat-resistant tape, and then a patch of rubber and aluminum foil was applied. However, this did not completely eliminate the air leak.

Roscosmos believes the crack does not threaten the ISS and the crew, but for now, ground specialists are deciding how to patch it up for a long time.
