How does NASA recycle urine
One component uses advanced dehumidifiers that captures moisture created by the breath and sweat of the crew, which is turned into drinking water. The other component pre-treats urine and then uses technology to distill it into water that can be recycled.
Where does astronaut pee go
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.
How does the ISS filter pee
One part of the ECLSS uses “advanced dehumidifiers” to capture moisture the station's crew breaths and sweat out as they go about their daily tasks. Another subsystem, the imaginatively named “Urine Processor Assembly,” recovers what astronauts pee with the help of vacuum distillation.
What was human urine used for
Humans have known for thousands of years that their urine is an excellent fertilizer for crops. It contains phosphorus, nitrogen and potassium—many of the same ingredients as commercial fertilizers.
What does NASA do with waste
Astronauts can process small pieces of trash in a high-temperature reactor, which breaks the waste down into water, oxygen, and other gases which the crew can use or vent as needed. Besides the gases, the remainder of the waste is greatly reduced in size, and no longer biologically active.
How do astronauts deal with periods
Most women opt instead to use contraceptives and put their periods on hold, both in preparation for and during spaceflight, as highlighted in the paper by Jain and her colleagues. “NASA flight surgeons are finding female astronauts just don't want to have to deal with their periods,” Jain said.
What is the astronaut peeing tradition
Wee on the bus
Astronauts are expected to stop the bus taking them to the launchpad and urinate on the back right wheel. This tradition dates back to Gagarin, who for some reason – and nobody seems quite sure why – insisted on stopping the bus taking him to the launch pad to take a leak.
Is pee 98% water
Urine consists of approximately 98% water, and 2% urea, which is made up of carbon, oxygen, nitrogen and hydrogen atoms.
Do astronauts drink filtered urine
But the US water recycling system produces more than the Russians' does. Nasa astronauts don't just filter their own urine – they also use their Russian colleagues'. “We collect it in bags, and then the crew hauls it over to the US side,” Carter told Bloomberg. “We don't do 100% of the Russian urine.
What color is urine
“Normal urine is pale yellow to amber in color and is clear. Darker urine is often a sign of dehydration.
What is the value of human urine
The common value for urine pH is 6.0–7.5 for most people, but any value within the 4.5–8.0 range is generally not a cause for concern. The pH scale runs from 1 to 14, with 1 being the most acidic and 14 the most basic.
Is space junk being cleaned up
Astroscale, a Japanese tech firm with a facility in Oxfordshire, hopes to offer a satellite removal service in the next few years. Meanwhile, Esa's ClearSpace-1 mission aims to become the first to remove an item of space debris from orbit in 2025.
Why don’t we dump waste in space
One is the risk: What if a rocket carrying tons of highly radioactive waste exploded on takeoff Another is the cost, which would be vastly higher than the already high price of storing it safely on Earth. There is also a lot of “space junk” already orbiting the planet, including broken satellites and meteor debris.
Do female astronauts wear a bra in space
According to NASA astronaut with over 30 years of experience, female astronauts generally wear bras in space, not for support, but for comfort and modesty. Cameras are placed all over the space station, and the bras can help protect their privacy from male astronauts.
What happens if a woman gets her period in space
Here Tereshkova poses with the Vostok 6 capsule she piloted over 50 years ago. Her space flight lasted 2 days, 22 hours and 50 minutes. Despite the lack of gravity, periods happen normally in space and do not cause 'reverse flow' as once feared.
Which astronaut wore diapers
astronaut Lisa Nowak
The film is loosely inspired by the life of NASA astronaut Lisa Nowak, who was widely reported to have worn a diaper on a 14-hour cross country drive to confront the new flame of her former lover, becoming the first astronaut ever to be arrested.
Who was the first astronaut to pee in space

How hot is pee
If the temperature of a urine specimen is outside the range of 90 °F to 100 °F (32 °C to 38 °C), that is a reason to believe the donor may have altered (e.g., adulterated or diluted) or substituted the specimen.
Is urine 5% water and 95% waste
Urine is about 95% water and 5% waste products. Nitrogenous wastes excreted in urine include urea, creatinine, ammonia, and uric acid. Ions such as sodium, potassium, hydrogen, and calcium are also excreted.
Do astronauts lose calcium through urine
Loss of Calcium:
The risk associated with bone loss during long-duration space travel is the increased levels of calcium in urine, known as hypercalciuria. As bones break down, the body releases the excess calcium into the excretory system, which leads to the risk of renal or kidney stones.
Do astronauts recycle their sweat
Efficient water recycling will be critical to long-term missions far from Earth. A new water recycling system on the International Space Station (ISS) recovered 98% of the water used by astronauts — a huge milestone that will help NASA explore deeper into space.
Why is my pee blue
Food coloring is the most common cause for blue or green urine. Vitamin B can also turn the urine green. Certain medications like amitriptyline (used for depression or pain), Propofol (sedation and anesthesia during surgery) or indomethacin (an Advil-like pain reliever) can also cause blue/green urine.
Is clear pee good
Transparent: While clear urine isn't exactly a bad thing, it can be a sign that you've been drinking too much water. Getting your daily intake of H2O is a good thing, but not when you're flushing all the electrolytes out of your body. Dark Yellow: This is a normal color, but may mean you need to sip on some water.
Is urine 95% water
Human urine is composed primarily of water (95%). The rest is urea (2%), creatinine (0.1%), uric acid (0.03%), chloride, sodium, potassium, sulphate, ammonium, phosphate and other ions and molecules in lesser amounts30 (Table 1). Protein is only found in trace amounts compared to their values in blood plasma.
What is human urine used for
Humans have known for thousands of years that their urine is an excellent fertilizer for crops. It contains phosphorus, nitrogen and potassium—many of the same ingredients as commercial fertilizers.
