Astronauts do not usually take a normal shower in space. On the International Space Station, they clean themselves with water from pouches, no-rinse soap, rinseless shampoo, and towels because gravity doesn’t pull water down a drain.

How it works

  • They squeeze a little water and soap onto their skin.
  • They use a towel or washcloth to wipe themselves clean.
  • For hair, they use special shampoo that does not need rinsing.
  • Any extra moisture is managed by the station’s air and water recycling systems.

Why not a regular shower?

Water floats in microgravity, so a normal shower would create drifting droplets instead of running off the body. Those droplets could get into electronics or other equipment, so astronauts use methods that keep water tightly controlled.

What it used to be like

On Skylab, astronauts had a tube-like shower setup, but it was slow and awkward, and it used limited water. On the ISS, the simpler wipe-and-wash method is the standard approach.
