Fission fragment rocket

Okay, so you know how sometimes when you play with Legos, you can take a big Lego block and break it apart into smaller pieces? Well, imagine that we do that with an atom instead.

Atoms are like tiny building blocks that make up everything around us, including rockets. When we break apart an atom, it creates a lot of energy, which we can use to make a rocket go really fast.

A fission fragment rocket is a special kind of rocket that uses the energy from breaking apart atoms to move forward. It works like this: when we break apart an atom, we create two smaller particles called "fission fragments." These particles are really tiny, but they fly away from each other super-fast, almost like they're exploding.

Now, imagine we put a bunch of these fission fragments inside a rocket engine. As they fly away from each other, they push against the walls of the engine and create a lot of energy. This energy can be harnessed to move the rocket forward at incredible speeds.

So in short, a fission fragment rocket is a type of rocket that uses the energy from breaking apart atoms to zoom through space like a speeding bullet. Cool, huh?
