Rocket, which obtains thrust from a rocket engine like a missile, spacecraft, aircraft or other vehicles. Rocket engine has an exhaust which is formed entirely from the propellant. This rocket engine works in two systems. One is action and another one is reaction. With the help of these two systems, a rocket can move forward simply by expelling their exhaust in the opposite direction at high-speed.

A rocket engine is mainly called as a reaction engine. This reaction is used for spacecraft propulsion as well as terrestrials use.

Rockets eject a high-speed jet to create their reaction mass.

There are many types of rocket engines. Some rocket engines are internal combustion engines.

The classic rocket has engines, which produced a high temperature, hypersonic gaseous exhaust. And it is only gained by the combustion of solid, liquid or gaseous propellant, containing an oxidizer and a fuel, within a combustion Chamber at high pressure.

To escape through a narrow hole, into a high expansion ratio nozzle and it is produced with the help of hot gas.

The effect of the nozzle is very important for converting most of the thermal energy into kinetic energy.

With the help of burning fuel, many rockets produced thrust. Most of the rocket used fuel for turning it into hot gas to move it forward. When the rocket tries to push the hot gas out of the engine by the back of the rocket then the rocket moves forward.

We can divide the rocket engines into two types. One kind of rocket use liquid fuel and another one use solid fuel. Liquid fuel used in the main engines on the space shutter. The Russian Soyuz also used liquid fuel. On the other hand, some rockets are using solid fuel. Fireworks and model rockets are also using solid fuel for flying.

The space like a vacuum and the rocket engines has nothing to push against the vacuum. It is a burning question for all that 'How does a rocket move there?'. We all knew the 3rd law of Sir Isaac Newton. The 3rd law of Sir Isaac Newton says that "for every action, there is an equal and opposite reaction." To move forward the rocket needs to pushes out its exhaust and then the exhaust also pushes the rocket. To move forward the rocket needs to push the exhaust backward and the exhaust makes the rocket to move forward.

Hybrid rocket propellant

There are used two types of propellant into a hybrid rocket. One is liquid propellant and another one is solid propellant. This two types of propellant are used in a rocket engine. The arrangement of the solid fuel is similar to that of the grain of a solid propellant rocket. And even there takes no burn on the surface of the grain. It is why there contains little or no oxidizer.

How does NASA use a rocket

NASA used rockets to launch satellites. NASA also used Sounding Rocket in order to scientific research. They used a rocket to send probes to other planets. Sounding Rockets go up and come back down. This types of rockets do not fly into orbit.

Uses of rocket

•At past rockets were used as a weapon of war. It was also used as an artillery after the invention of the canon.

•To determine the make-up of the upper atmosphere, sounding rockets were used greatly.

•Rockets are now using to exploring spaces.

•Rockets are also used for traveling.
