Kevin Costner didn’t actually drink his purified urine in Waterworld, but if we’re to have a future in outer space, we must learn to (so to speak) make a meal of our movements. The efficient recycling of astronaut wastes is just one problem that Purdue University researchers will be tackling after landing a $10 million, five-year grant to lead the NASA Specialized Center of Research and Training (NSCORT) for Advanced Life Support. Food technology, oxygen generation, water filtration and biomass production must all be integrated within any life support system if we’re to recreate the circle of life on, say, the International Space Station or in a Martian space colony.
