What are spacesuits?

A spacesuit is like a superhero costume that lets astronauts walk outside a spaceship in the super-cold, airless world of space.

Imagine you're wearing your warmest winter coat, thick socks, and gloves when it's freezing outside. Now imagine you’re also wearing a helmet so you can still see and breathe. That’s kind of what a spacesuit is, but even more special!

A spacesuit fits tightly on the astronaut, almost like a second skin. It has layers that keep the astronaut warm, protect them from tiny space dust, and let them move around easily.

Inside the spacesuit, there’s air to breathe, just like in a spaceship. If something goes wrong, the suit keeps the astronaut safe, it's like having a mini spaceship all around you!

Sometimes astronauts even have little tools attached to their suits so they can fix things in space, like putting up a new part on the International Space Station!
