Rockets promise the reach of great altitudes


Rockets are not modern invention.

For example, flying rockets of fire terrified the Mongolian soldiers and they fled after giving up an attack during the Imperial period. Rockets of fireworks were used to celebrate an important occasion for King George II. Copenhagen was burned to ground when the British used huge amount of rockets in an attack.

Rockets reach greater heights because of the thrust, the higher the exhaust velocity, the greater the thrust. A Russian is the first to accept the importance of the velocity of the exhaust at the base of rockets. However, an American interest to lift scientific tools to high altitudes is the beginning.

Giant rockets open the way to marvelous exploration of the vast heavens.

The first stage thrust is the most powerful to get the rocket overcome gravity. Once the fuel is empty, the mighty booster is drop to remove drag. Parachutes slowed its fall and retrorockets slow it to zero speed before the mighty booster hit the ground. The second stage booster thrust the rocket to the third phase and the same way, the booster is again drop. This process is repeated for the third stage and the fourth stage before the rocket become a space capsule.
