Do astronauts urinate in spacesuits?

In the latest video released by the European Space Agency, astronaut samantha cristoforetti, who works in the International Space Station, shows us how astronauts go to the toilet in outer space.

In the video, samantha cristoforetti holds a mysterious tube, which is a tool for all astronauts to urinate. The use of this tube is actually very simple. Turn on the switch and the pipe will suck out the liquid you discharged.

On the issue of defecation, because of weightlessness, the toilet in the space station is designed to be a little small, and its working principle is the same as that of the pipe mentioned above. As long as it is in the right position, the toilet will suck shit in. Finally, you need to pack the excrement in a cleaning bag, and you can't throw it away in outer space.

This is the way for the staff on the space station to deal with their physiological needs. Today's spacewalk astronauts still use diapers, which are "high-tech" gadgets.

However, wearing diapers for a long time is not feasible. If "human excrement" is not treated well for a long time, it will lead to physical problems for astronauts and serious infection.

So NASA launched a challenge collection to seek help from wise people all over the world.

These are three highly feasible schemes:

1.——M-PATS excretory system

It is connected to the crotch of the astronaut through a small air lock, and has a built-in washing basin, water circulation system and waste collection device, so it is necessary to design a special underwear.

2. Aerodynamic spacesuit waste treatment system

This is an aerodynamic system device similar to a belt, which directly sucks garbage through a "drainage pipe" and dries and disinfects it in time.

3. "Waste underwear" that can last for 6 days

It is a pair of tights with many ducts, which are connected to two waste disposal bags on the outer thigh, and can separate and disinfect waste.

In short, it is difficult to deal with physiological problems in space.

Female astronauts may have more inconvenience in space. But sending a woman to heaven can help us understand the physiological, psychological and space medical characteristics of a woman living and working in space, as well as the special needs to ensure her effective life and work. From a technical point of view, our preparations for female astronauts to participate in space flight are quite certain.
