How do spaceman go to the bathroom?

Answer 1

There is no gravity in space, so water in a bowl doesn't really work for toilets in space as it does on earth. Rather, NASA used the force of air to dispose waste. They developed a toilet for zero gravity using vacuums. Hoses may be used for urine, but the toilet itself also uses a suction system. Straps hold the astronaut's feet to the floor while a folding bar keeps him/her on the toilet. After the process, the wipes are disposed by a separate contraction.

What is done with the waste? The solids are compressed and stored on the craft while the liquids are vented into space.

Answer 2

Astronauts in space use vacuum toilets that utilize airflow to remove waste. They also have special equipment like thigh cuffs and waist belts to help them stay in place while using the toilet in microgravity environments. Waste is then stored or processed onboard the spacecraft.
