Crew in no danger after ISS issues resolved: Russia
The crew had reported overnight that the toilet on the Russian segment of the ISS was out of order, that the water systems used to supply oxygen to the crew were empty and that there were problems with heating food.
The orbital lab's first module was launched over two decades ago in 1998 and there have been growing concerns about its age.
Last week, the oxygen supply system in the Zvezda module of the Russian segment of the station failed. Roscosmos said at the weekend that this has now been repaired.
A small air leak that was detected in August has also now been patched up, after tea leaves from a torn tea bag helped alert the crew to the site of the leak.
Quoted by the RIA Novosti news agency last week, veteran Russian cosmonaut Gennady Padalka said that the Russian equipment on the ISS was well past its use-by date.
"All modules of the Russian segment are exhausted," said Padalka, who holds the world record for most days spent in space.
He added that the two-decade-old equipment should only be used for 15 years.
