How do astronauts bathe in space?

1. When taking a bath in space, astronauts must wear a special breathing nose and mouth mask and breathe the air outside the shower directly through the pipe. The shower system must also be equipped with a centrifugal water-gas separator, so that the water-gas mixture can be sucked out and separated, and then the water can be transported to the reclaimed water treatment system for recycling.

2. In the current space capsule, a shower room will be built for astronauts, which is covered by a curtain outside, which plays a very good role in protecting the personal privacy of astronauts. The way for astronauts to take a bath is actually to wipe their bodies with wet towels, which is simpler than the above.

3. Shampoo and shower gel equipped in the spaceship are special for space flight, and they are generally washless, that is, when astronauts take a shower, they just need to apply them to their hair and body without washing them with water. The spacecraft will regularly distribute towels and toiletries to astronauts to meet their bathing needs.

Precautions for astronauts in space

Avoid being hit by foreign objects in space. This kind of "collision" is not hit by a passing meteor, but here refers to micrometeoroids and tiny metal fragments. Micro meteoroids, also known as micrometeorite, micro meteors or meteor dust, are very small, just small particles of dust-like rocks; Metal fragments are also small fragments, which may have fallen from the spaceship and so on.

Although these foreign bodies are only the size of rice grains or even dust, they may still penetrate the spacesuit at high speed, causing air leakage. Astronauts must regularly check whether the spacesuit and gloves are leaking during the spacewalk.
