Rockets

Rockets can be divided into two main categories. Examples of these include solid fuel rockets and liquid fuel rockets. 

For solid fuel rockets, the fuel and oxidizer are burned in the same tank, and any fuel that can produce a large volume of oxygen can be used as the fuel.

 

Examples of solid fuels include trinitrotoluene, trinitrotoluene, and gunpowder.

In liquid fuel rockets, the fuel and oxidizer are stored separately and are burned separately to obtain the thrust required to lift the rocket. 

Examples of liquid fuels include gasoline, kerosene, alcohol, and liquid hydrogen, while oxidizers include liquid oxygen and hydrogen peroxide.

Since rockets are expensive to manufacture, most space travel today uses space shuttles.
