Learn English: Space Sleep: How Astronauts Snooze in Zero Gravity (easy)

Astronauts living in space have to sleep in special places called sleeping cabins.

These cabins are like little phone booths where astronauts can snuggle into a sleeping bag.

The sleeping bag keeps them from floating around while they sleep.

Astronauts can sleep in any position because they don't feel like they're upside down!
