And not just any water, but the astronauts own urine. Science Daily reports on a new breakthrough that will double the number of astronauts who can stay aboard the International Space Station (ISS) by recapturing and purifying their urine and turning it into clean water:
The article notes that because it is extraordinarily expensive to ship clean water to the ISS — $15,000 a pint — they attempt to recover every drop they can, including condensation from showers and even water vapor that builds up in the astronauts’ space suits. Now thanks to research done in the 1990s at Michigan Tech University, they can recover urine as well:
Until now, however, NASA has not attempted to tap one major potential source of water: urine. That will soon change with the deployment of the new Water Recovery System. It departs Friday, Nov. 14, from the Kennedy Space Center on the Space Shuttle Endeavor.
The Water Recovery System, made possible in part by researchers at Michigan Technological University, can transform ordinary pee into water so pure it rivals the cleanest on Earth.
NASA praised the Tech researchers:
NASA’s Layne Carter, the Water Recovery System lead engineer at Marshall Spaceflight Center in Huntsville, Ala., credits Hand and the rest of the Tech research team with making the system as good as it is. “Without a doubt, if it hadn’t been for their modeling effort, we never would have been able to redesign the multifiltration beds and achieve that level of efficiency,” Carter said. “They did a fantastic job.”
The new filtration system will save NASA around $600,000 a year. I can’t help but think, however, that applications to be astronauts may go down.
