Astronauts Drink Recycled Urine

We've become increasingly aware lately of how valuable and how scarce potable water is in some parts of the world, but no where is it more scarce than 200 miles up at the International Space Station. Up there you can't take any resource for granted, and a resource as valuable as water can't be pissed away. That is why NASA has installed a urine recycling system. Yesterday astronauts aboard the space station put the system to use for the first time, and with a toast and a smile they downed their first glasses of recycled urine produced by the system.
