From Telegraph UK:
"As NASA prepared to double the number of astronauts living aboard the International Space Station, nothing did more for crew bonding than a machine being launched aboard the space shuttle Endeavour on Friday
It's a water-recycling device that will process the crew's urine for communal consumption.
"We did blind taste tests of the water," said NASA's Bob Bagdigian, the system's lead engineer. "Nobody had any strong objections. Other than a faint taste of iodine, it is just as refreshing as any other kind of water."
"I've got some in my fridge," he added. "It tastes fine to me."
...Reusing water will become essential once NASA retires its space shuttles, which produce water as a by-product of their electrical systems. Rather than dumping the water overboard, NASA has been transferring it to the space station."
