Urine is boiled in the distillation assembly and delivered to the water processor, where it undergoes a cycle of filtration and chemical purification until it is usable by the crew – reducing costs associated with launching heavy water shipments to the station from Earth.
How does NASA turn urine into drinking water?
For urine, astronauts use a funnel and hose that has a fan that pulls urine away into the water filtration system. For fecal matter, astronauts do their business through a small hole in the toilet seat. A fan then pulls the waste into a plastic bag, which is then compacted into a removable fecal storage canister.
Does NASA recycle urine?
In 2009, NASA astronauts began recycling urine using the Urine Processor Assembly, which is able to reclaim 75 percent of water from urine. … Once the urine is treated with AUP, it is distilled and filtered in the station’s Water Reclamation System, before finally making it to an astronaut’s drinking glass.
What do the astronauts do with the recycled urine?
Pee is more than 90% water. Since water is heavy and takes up a lot of space, it is better to recycle pee rather than bring up clean water from Earth. All astronaut pee is collected and turned back into clean, drinkable water. Astronauts say that “Today’s coffee is tomorrow’s coffee!”
Can you turn pee into clean water?
Scientists from Belgium built a solar-powered machine that can turn urine into drinkable water. … Using membrane distillation, the scientists were able to remove 95 percent of ammonia from the urine.
Do astronauts wear diapers?
A Maximum Absorbency Garment (MAG) is an adult-sized diaper with extra absorption material that NASA astronauts wear during liftoff, landing, and extra-vehicular activity (EVA) to absorb urine and feces. It is worn by both male and female astronauts.
How do astronauts drink their own urine?
Luckily for science, someone figured out a method. Unluckily for the astronauts, it’s turning their own pee into potable drinking water. … The end result is what she calls “good clean urine distillate” that gets put into a water processor for further filtration before the astronauts actually consume it.
How is pee recycled?
In our process, freshly collected urine is first made alkaline (high pH) to prevent the reaction that produces ammonia and urine’s typical pungent smell. Then, by evaporating water, urine is reduced into a dry powder that captures all its nutrients.
How do astronauts get water to drink?
Astronauts living and working 400 km above our planet might prefer not to think about it, but the water they drink is recycled from their colleague’s sweat and exhaled breath – collected as condensation on the Space Station’s walls.
Do you drink your own pee in space?
Astronauts have been drinking distilled urine since 2009, and they currently recapture 93 percent of wastewater, but the system they’re using now is heavy, slow and has been prone to breaking down. It spins the urine at high speed to separate out the water vapor, then treats it chemically.
Can you boil urine to make water?
Boiling will eliminate most microbial and parasitic hazards, though not all. It won’t do anything to eliminate most chemical toxins. Urine is usually biologically safe and not seriously toxic, but contains enough dissolved salts, urea, and so on that it’s not as effective at rehydrating you as water is.
Can you drink urine?
A healthy person’s urine is about 95 percent water and sterile, so in the short term it’s safe to drink and does replenish lost water. But the other 5 percent of urine comprises a diverse collection of waste products, including nitrogen, potassium, and calcium—and too much of these can cause problems.
