The crew of the International Space Station (ISS) tasted their own urine
Wednesday — and NASA didn’t even have to double-dog dare them.
Astronauts celebrated by “clinking” their drinking bags together in a traditional cheers before sipping water composed of recycled urine, sweat and atmospheric moisture. The cheers marked the initiation of a closed loop water recycling system aboard the ISS.
NASA claims each crew member creates about a gallon of water from urine every six hours, but the source water doesn’t just come from the space station’s human occupants. “Lab animals on the ISS breath and urinate, too, and we plan to reclaim their waste products along with the crew’s. A full complement of 72 rats would equal about one human in terms of water reclamation,” Layne Carter, a water-processing specialist with NASA, said in a statement released by the space agency.
