How astronauts walk the toilet

We are all human and it is clear that we put the waste of our life somewhere, or rather we go to the toilet. Recently I asked myself: How do they go to the toilet in SPACE? Anyone who knows the law of universal gravitation, which by the way does not work there, will understand that this is not an easy matter.

The toilet bowl at the orbital station is designed for both men and women - it looks exactly the same as on Earth, but has a number of design features. It is equipped with leg braces and hip holders, and powerful air pumps are built into it, which help to remove all the bad things that come out of the astronauts. The astronaut is fastened to the toilet seat with a special spring fastener, then turns on a powerful fan and opens the suction port, where the air flow carries all the waste.

After suction, all waste is split into oxygen and water, these components of human liquid waste are launched into a closed OS cycle. On the ISS, air from toilets must be filtered before entering living quarters to remove bacteria and odors.

Interesting that:

On the shuttle, it was possible to pee while standing - for both men and women. For this, a special funnel was developed with a hose that was connected to the toilet. If desired, the astronaut can use it while sitting. The sewerage system separated solid waste from liquid waste. The solids were pressed and stored aboard the shuttle, and unloaded after landing. Liquid waste was thrown into outer space.

During the launch from the cosmodrome, landing and spacewalk, astronauts wear special diapers.

Currently, space toilets are not matched with the same diligence for each crew member. But for the first cosmonauts, personal toilets were created. Several research institutes have been working on this. The dimensions of the “fifth point” of those preparing for the flight were carefully measured. Until now, in one of the research institutes, Valentina Tereshkova's "bronze backside" has been preserved, which was created from an individual cast from the body of a woman-cosmonaut.

If both lavatories fail on the ISS, then as a last resort, you can visit the lavatory in the Soyuz spacecraft docked to the OS.

The toilet installed in the American segment of the ISS was manufactured in Russia by order of NASA due to the fact that the United States does not possess such technology. The cost of the toilet is about $ 19 million.
