Recycled Urine As Drinking Water For ISS Astronauts

NASA ISS Urine Recycling Space Shuttle Endeavour will take off for the International Space Station this Saturday, to deliver a device capable of recycling urine into water. This is one of the many devices needed to expand the ISS from a habitat of three people, into one that can fit six crew members. Other devices include two new sleeping compartments, various exercise gear, a toilet and a galley.

The $250 million urine recycling system will use a process of distilation, filterization, ionization and oxidization to turn "yesterday's coffee into today's coffee" as one NASA astronaut puts it.

The recycling system will first be tested in the zero-gravity environment, and the water will be sampled by engineers back on Earth, before being used by the astronauts on the space station. The device has already been tested on Earth, and samplers could not taste any difference between tap water and the water extracted out of urine.

Bob Bagdigian of NASA, oversees the development of the water recycling system. He explained that the only comment often heard about the recycled water is the faint taste of iodine, which is necessary to control microbial growth. "Other than that, it is just as refreshing as any other kind of water," Mr Bagdigian said. "I've got some in my fridge. It tastes fine to me."

"Some people may think it's downright disgusting, but if it's done correctly, you process water that's purer than what you drink here on Earth," said astronaut Heidemarie Stefanyshyn-Piper.

NASA has ten more flights left for the space shuttle program, and one single flight left for this year. The space shuttle program will retire in 2010.

Congrats,

i appericiate to this kind of recycle ideas.
Now-a-days have some opposition to this idea.
But in future, all of them told its good for
human.

There could have been 1000s of better ways to storing water(H2O) than recycling the urine.

The first thing come to my mind after reading this is "its disgusting".

by Samantha Whyte on Thursday, June 18th 2009 at 03:06 PM

i must admit that the first thing that came to my mind when i heard this was 'ewww' however i do see the possiblities and the benefits of recycling system. Say, for instance, countries that have issues with water pollution or suffer from drought- THIS COULD BE A BLESSING TO THEM
also if after a storm (hurricane) where it could be a while b4 you can get back your regular water supply - this system could be made available for us ....... ahhhh the possibilities with using technology ....... great job NASA !!!!!!

Fantastic...... lets start to implement this technology here on Earth.
