On Crowded Space Station, Broken Urine Recycler a Problem
{{#rendered}} {{/rendered}}A broken device that recycles astronaut urine into clean drinking water on the International Space Station may have a slight impact to life onboard next week when NASA's shuttle Atlantis arrives to boost the number of people there to 12.
Any impact would likely pertain to things like digging into supplies of spare urine bags (to hold stuff that would normally have been recycled), or determining how many astronauts can use the two bathrooms on the station, or the one on Atlantis, NASA spokesperson Kelly Humphries told SPACE.com. The space station has plenty of water to support its six astronauts through next spring with or without the recycler, he added.
"If we can't get it running again, yes it will have an impact because there are no spare parts manifested for the shuttle mission," Humphries said.

Engineers hope they can revive the recycling device, known in NASA parlance as the Urine Processing Assembly (UPA), by the time Atlantis and its crew of six astronauts blast off on Monday. But they are also developing back up plans if the problem persists. If the shuttle launches on time, it will arrive on Wednesday.
The glitch has not affected use of the station's newer, second bathroom, which is tied into the recycling system and is vital to supporting six people aboard the orbiting laboratory and periodic population booms when shuttles are docked, NASA officials said.

That mix is then filtered through a seven-step process until it is pure enough to drink or use for food preparation, bathing, oxygen generation or any other purpose.
Station astronauts began drinking their recycled urine in May.
The most recent breakdown for the urine processor, which has had glitches before, occurred Oct. 30. Astronauts removed a clog in its intricate plumbing and were testing the fix when they saw it break down again.

Atlantis' six-astronaut crew is poised to fly an 11-day mission to the space station to deliver vital, and large, spare parts for the orbiting lab. Three spacewalks are planned to make the delivery.
The space station is currently home to six astronauts — two Americans, two Russians, a Canadian and Belgian spaceflyer Frank De Winne of the European Space Agency, who commands the team. One crewmember, NASA astronaut Nicole Stott, is due to return home aboard Atlantis when it leaves the station later this month.

The unmanned Mini-Research Module 2, named Poisk (Russian for "explore"), docked to a rooftop berth on the station's Russian-built Zvezda service module. It can be used as a research space, for storage, as well as an airlock or docking port.
