The ISS (the International Space Station) is troubled again by an air leak. A recent report indicated how the cabin loses daily a minute amount of air.
According to NASA, the air loss on the ISS has risen now above a level that can be explained by the average ISS day-to-day. Mission control first observed something strange in September last year, but the increase in air leakage was little, meaning it wasn’t enough to cause any concern.
Now that rate has increased, NASA is buckling in to discover where the extra air is escaping. Here is what you need to know.
The ISS is Still Troubled by Air Leak: What to Expect
A recent report indicates the ISS is experiencing another air leak, but we shouldn’t worry. The ISS crew, currently at the location, aren’t in any danger, but NASA astronaut Commander Chris Cassidy and Roscosmos cosmonauts Anatoly Ivanishin and Ivan Vagner will have to hole up in the Zvezda Service Module for the weekend while mission control looks for the source of the air leak.
The previous air leak occurred two years ago, and it was discovered by ground control at 23:00 UTC on 29 August 2018. The space station modules were sealed off, and their atmospheric pressure was investigated, while the crew moved to the Russian segment.
That procedure ceased the leak to the Soyuz MS-09 spacecraft and was temporarily attached to the ISS’s Rassvet module at that time. It was then traced to a tiny, two-millimeter hole with drill tracks next to it, leading to the thought that a manufacturing mistake was the one to blame.
During the Zvezda module, the ISS crew will have to continue their duties. Once the air leak has been traced to a particular module, the crew will have to do a detailed search to find the exact cause.
