Have you ever considered how astronauts use toilets in microgravity on the ISS? Currently, Hank Green, a scientist from Montana, USA, explains the use of microgravity toilets that people are eager to know.
Method steps.
Green noted that astronauts use an inhalation system to defecate and defecate, and some of the excreted urine will be recycled in the space station's life supply system. The toilet seats that people use on Earth are about 30-45 centimeters in diameter, but in space, astronauts must "align" an opening device with a diameter of 10 centimeters when urinating.
They use fixtures to stabilize themselves on the toilet seat, making sure no excrement is spilled. To train astronauts to do this, NASA designed a toilet with a camera inside that allowed them to practice alignment while squatting on the toilet.
"Space toilets work very much like vacuum cleaners, using different air pressures to suck up solid feces," Green said. Astronaut feces are not discarded in space, but stored on the space station and then returned to Earth. ”
The space urination device is cleverly designed to provide each astronaut with a private pee funnel device that connects to a hose interface that will suck urine into a small urinal pool when the astronaut urinates. Green explained that the urinal devices for male and female astronauts are different, and that female urinals are actually simpler and easier to operate. They can use the urinal device directly to their body, which is more difficult for male astronauts to use, because they must bring the urinal device close to their body to collect urine, but not so close that the inhalation device can cause harm to the male reproductive organs.
The cost of a space toilet on the space station is high, reaching $19 million, and the total cost of the equipment is about $100 million, because the urine treatment equipment is very complex. In 2008, astronauts began using a new system capable of purifying and distilling urine into water. The urine can be recycled and eventually used for astronaut drinking and bathing.
To isolate the dirt in the urine, the space station has a barrel-sized rotating still, which is capable of creating an artificial gravitational pull to boil the liquid. At the same time, NASA wants to use urine to generate electricity through "forward osmosis" treatment.

1. The problem of space catering
First of all, let's talk about their food, generally speaking, their food has been transported by the freight warehouse half a month ago. In the early days, astronauts' food would be made into the shape of toothpaste, but now astronauts in space eat everything from grilled fish to spicy snacks to yogurt and chocolate. >>>More
Although astronauts are a special group, they are also normal people and also need to eat, drink and lazar, but how do astronauts go to the toilet on the space station? Astronaut Samantha Cristoforetti, who works on the International Space Station, demonstrates this mysterious and "dirty" process. >>>More
With the large-scale spacecraft and the improvement of environmental control systems, astronauts can eat without helmets or even spacesuits. On the Skylab orbital station in the United States, in addition to heaters for serving hot food, there are also refrigerators. The shuttle's galley has been able to store more than 100 kinds of food, and the crew can eat different meals every day. >>>More
