How do space tourism rockets actually work?

A space tourism rocket is like a super-fast elevator that takes you all the way up to space.

Rockets work by pushing really hard against the air below them. Think of it like when you jump on a trampoline, you push down, and the trampoline pushes you up. Rockets do something similar but with fire instead of a trampoline. They burn special fuel that makes a lot of hot gas go whoosh out the back really fast. This whoosh is what sends the rocket flying upward.

How rockets get going

Inside a rocket, there’s a big engine that mixes two kinds of fuel, like mixing chocolate and vanilla ice cream, to make a powerful explosion. The hot gas from this explosion rushes down and out the back of the rocket, which pushes it up into the sky.

As the rocket goes higher, it gets lighter because it uses up its fuel. That makes it go even faster, just like how you can run faster when you're not carrying a heavy backpack.

When the rocket is high enough and going fast enough, it lets go of its fuel tank, kind of like throwing away your empty water bottle after you finish your drink, and keeps floating up to space.
