There's more than one toilet on the ISS, and there's more than one oxygen supply system that provides precious air for the crew in orbit.
An oxygen supply system in the Russian-built Zvezda module of the station failed Wednesday, according to an AFP report.
It's not the only oxygen generation system on board, so the crew of six -- which includes three new arrivals from NASA and Roscosmos -- is not in danger.
A Roscosmos spokesperson told AFP that the crew will work to repair the issue this week.
NASA describes it as "the early cornerstone for the first human habitation of the station."
The crew and ground controllers have been trying to track down a lingering air leak that was recently traced to the Zvezda module.
There's no indication yet if there's a connection between the leak and the oxygen system. »
