How do astronauts go to the toilet when they live in space?

On the space shuttle or space station, there are special toilets. Of course, this is different from the one on the ground, it requires special facilities, usually it is located in the room of the waste management cabin, and there is a funnel-shaped urine collector in the toilet, and the urine is ventilated in the urinal to absorb the excreted urine into the internal collection bag. The collection bag should be changed once a day.

The air should be expelled when collecting so that the urine does not float around.

There is also a penetrating water filter bag embedded in the bulkhead, which is replaced every time it is used. The water filter bag passes through the air stream to solidify the feces. In order to grasp the life of astronauts in space, astronauts have to freeze part of their urine and urine into specimens every time they go to space, which can be analyzed and studied by scientists when they return to Earth.

According to foreign media reports on the 11th, Britain's Prince Philip raised the question of how astronauts can relieve themselves in space when he visited the U.S. Space Flight Center. So, how exactly do they go to the toilet?

This matter is closely related to the air flow. On Earth, at least in the West, the standard toilet is a water flush that flushes down a pipe to flush excrement. Weightlessness on the Space Shuttle and the International Space Station meant that a set of water-flushed guards was impossible.

On the space shuttle, both urine and feces are carried away by the rapid air currents. This unisex toilet resembles a regular toilet, but with straps on the feet and railings at the thighs to ensure that the astronauts do not deviate from the middle.

In space, how do astronauts go to the toilet?

Different times are different, and now the space station has a special toilet.

Toilets use a system that separates excreta, solid and liquid waste. The solid waste is then dehydrated and flattened, packed into a special reservoir, left on the spacecraft, and then unloaded when the spacecraft lands and returns to the ground. And some of the liquid waste is sprinkled in the space.

The International Space Station, on the other hand, will pass these liquids through the circulation system, convert them into drinking water, and recycle them.

Astronauts carry a small bag in space, and this bag holds urine.

These liquids are converted into drinking water and recycled.

There is an air pump in space to help astronauts go to the toilet.

According to reports, there is also a toilet in the spacecraft.

It's not that there are no bathrooms.
