The International Space Station is a large spacecraft. It orbits around Earth. It is a home where astronauts live.
The space station is also a science lab. Many countries worked together to build it. They also work together to use it.
To keep clean, astronauts clean themselves with alcohol, or towels with soap. They must use rinseless shampoo and swallow their toothpaste.

Using the restroom in space is not as convenient as on Earth. Astronauts must first strap themselves onto toilets, which suck the water like a vacuum.
To sleep, astronauts have sleeping bags in cabins instead of beds. Similarly, they must strap themselves to avoid floating in space. The Ventilator fan must be used because it keeps air flowing. Without this essential item, there will be too much carbon dioxide in their cabins and this is fatal.
The lack of gravity in space makes astronauts lose muscles and even bones. To keep these strong, they must exercise using machines or equipment like treadmills.
