ISS new urine recycler passes

In cost $174 million, though how that money breaks down its real cost is not known. Further testing is needed before the future expanded crew of the International Space Station is cleared to do precisely what the crew of Apollo did as early as 1968.

Recycle urine into drinking water.

While some are reporting the use of such a system will not outlast the lifetime of ISS, its difficult to see how the Armstrong South Pole-Aitken semi-permanently manned lunar station will get along without it. I want to learn more, whether it is a true closed system, for example.
