Space Travel

What Is Space?

Space is a big, dark place up high. It is full of stars, planets, and moons. There is no air in space, so we need special suits to breathe.

How Do Rockets Fly?

A rocket pushes out hot fire from its bottom. The fire pushes the rocket up, like blowing up a balloon. The rocket goes higher and higher until it reaches space.

What Astronauts Do

Astronauts wear big helmets and suits. They float inside the spaceship because there is no gravity. They look out the windows and see Earth look like a blue ball.
