ISS oxygen supply system in Russian module fails but crew is OK

The ISS is facing a couple of issues with an ongoing air leak and issues with an oxygen supply system in the station’s Zvezda module.


The International Space Station is about redundancy. There is more than one toilet on the ISS, and there is more than one oxygen supply system that provides precious air to the crew in orbit. It is still not good when one of these systems fails.

An oxygen supply system in the Russian-built Zvezda module at the station failed on Wednesday, according to an AFP report. That is it not the only oxygen generation system on board, so the crew of six ̵

1; which includes three newcomers from NASA and Roscosmos – is not in danger.

A Roscosmos spokesman told AFP the crew will work to repair the problem this week.

Zvezda has been in orbit for 20 years. NASA describes it as “the early cornerstone of the station’s first human habitation.” It contains housing, aircraft systems and life support systems.

This is the latest in a series of air-related issues on the ISS. The crew and ground controls have tried to track one down prolonged air leakage recently traced to the Zvezda module. There is no indication yet if there is a connection between the leak and the oxygen system.

CNET reached out to NASA, but did not immediately respond.
