This Wednesday (14), the oxygen supply system of the Zvezda module, in the Russian segment of the International Space Station (ISS), failed. Despite the incident, you can rest easy: Roscosmos, the Russian space agency, said the crew was not in danger.
The problem was identified after the arrival of Kate Rubins, Sergey Ryzhikov and Sergey Kud-Sverchkov to the orbital laboratory for Expedition 64, and now the orbital laboratory has six crew members, while Expedition 63 personnel do not return home. This failure is the most recent incident on the ISS, and occurs after an air leak that has puzzled teams for some time; this leak was first detected about a year ago, and since then the crew and crew on the ground have been searching for the exact source of the problem.
It is worth remembering that this issue of leakage does not cause any danger to the crew either – the station is not completely airtight, so there will always be some air leaking. Furthermore, even with the oxygen supply problem, the secondary system of the US segment is operating normally. “Nothing threatens the safety of the crew and the ISS,” said a Roscosmos representative. The repair of the problem will start later this Thursday.
Gennady Padalka, a veteran cosmonaut, commented that the equipment in Russia has already ended its useful life: “all modules in the Russian segment are exhausted,” he said, who also stressed that the equipment should only be used for 15 years, but that they have arrived two decades of use.
