True fact: Astronauts Drink Recycled Urine Water
Drink up: Space station recycling urine to water
May 20, 9:21 PM (ET)
By SETH BORENSTEIN
HOUSTON (AP) - At the international space station, it was one small sip for man and a giant gulp of recycled urine for mankind.
Astronauts aboard the space station celebrated a space first on Wednesday by drinking water that had been recycled from their urine, sweat and water that condenses from exhaled air. They said "cheers," clicked drinking bags and toasted NASA workers on the ground who were sipping their own version of recycled drinking water.
"The taste is great," American astronaut Michael Barratt said. Then as Russian Gennady Padalka tried to catch little bubbles of the clear water floating in front of him, Barratt called the taste "worth chasing."
He said the water came with labels that said: "drink this when real water is over 200 miles away."
The urine recycling system is needed for astronaut outposts on the moon and Mars. It also will save NASA money because it won't have to ship up as much water to the station by space shuttle or cargo rockets.
It's also crucial as the space station is about to expand from three people living on board to six.
The recycling system had been brought up to the space station last November by space shuttle Endeavour, but it couldn't be used until samples were tested back on Earth and a stuck valve was fixed on Monday.
So when it came time to actually drink up, NASA made a big deal of it.
The three-man crew stood holding their drinks and congratulated engineers in two NASA centers that worked on the system.
"This is something that had been the stuff of science fiction," Barratt said before taking a sip.
NASA deputy space shuttle manager LeRoy Cain called it "a huge milestone."
On the Russian side of the space station, moisture in the air - not urine - is turned into drinking water.
The new system takes the combined urine of the crew from the toilet, moves it to a big tank, where the water is boiled off, and the vapor collected. The rest of contaminants - the yucky brine in the urine - is thrown away, said Marybeth Edeen, the space station's national lab manager who was in charge of the system.
The water vapor is mixed with water from air condensation, then it goes through filters, much like those put on home taps, Edeen said.
When six crew members are aboard it can make about six gallons from urine in about six hours, Edeen said.
Some people may find the idea of drinking recycled urine distasteful, but it is also done on Earth, but with a lot longer time between urine and tap, Edeen said. In space, it takes about a week, she said.
The technology NASA developed for this system has already been used for quick water purification after the 2004 Asian tsunami, Edeen said.
Wednesday's urine celebration included subtle bathroom humor.
"We are happy to have this water work through the system - we're happy to have it work through our systems," Barratt said.

How do you think Navy ships get drinking water? You think we bring it with us? No....we made it with ocean water with a friggin' distilling plant. Last ship I was on could make 160,000 gallons a day.

I was told (no backup info) that a representative of a water processing company drank water from a miniature version of a water purification plant to sell his product.
Here's to ya.

Re: True fact: Astronauts Drink Recycled Urine Water
if they were truly adventurous, they should know that they can drink their own untreated urine about 7 full cycles of in and out of the body before being poisoned by it.

Sure, after 6 or 7 untreated trip through, they'd get sick, but their teeth would sure be white!

Re: True fact: Astronauts Drink Recycled Urine Water
i actually drank recycled urine once just to make sure i could actually make it work...
all it requires is a clear plastic bag, the sun, and a full bladder.
solar stills are a good thing to know how to make...and very easy to make. they don't produce a lot of water, but they produce enough to be the difference between life and death. you can get water from urine, vegetation, dirt, etc. etc.F*S=k
