Internal drive propulsion

Internal drive propulsion is how a space rocket moves forward while in space. Think of it like blowing up a balloon and letting it go. When you let the air out of the balloon, it zooms across the room. The space rocket uses a special engine that works kind of like that. Instead of just blowing air out of the back of the rocket, the engine uses special fuel to create a big explosion in the engine.

When the explosion happens, it creates a lot of hot gas that shoots out of the back of the engine. That gas pushes against the inside of the rocket, which makes the rocket go forward. This is called thrust. The more thrust the engine produces, the faster the rocket goes.

But how does the engine make the explosion in the first place? This is where things get a little bit more complicated. The fuel that the engine uses is often made up of chemicals like hydrogen and oxygen. When these chemicals mix together and burn, they create a lot of heat and gas.

The engine has special tanks that hold these chemicals separately. When the pilot wants to go forward, he or she will send a signal to the engine to start mixing the chemicals together. This causes an explosion in the engine, which creates thrust, and the rocket starts moving forward.

So to summarize, internal drive propulsion is the way a space rocket moves forward by using a special engine that creates an explosion using special fuel, which produces thrust that pushes against the inside of the rocket and propels it forward.
