Thank heavens -- the $154 million water recycling system, which is designed to convert sweat, moisture and urine into an ingestible fluid, um, works. According to NASA, the Urine Processor Assembly (UPA) managed to get through three rigorous testing sessions, and apparently that was good enough for officials to leave it in orbit. So yeah, theoretically we now have a way to keep long-term space cadets hydrated for months, but is anyone really going to volunteer to pinch their nostrils and toss back the first shot? Our sources point to "no."
