Essay, Paragraph or Speech on “Rockets” Complete English Essay, Speech for Class 10, Class 12 and Graduation and other classes.



In 1903, a Russian school teacher Konstantin Tsiolkovski developed the first scientific idea on rocket propulsion. However, it was not until 1926, when first liquid fuel rocket was built and launched by American engineer Robert Goddard.

Rockets burn large quantity of fuel in order to make thrust that pushes them upward. Rockets are driven by stream of gases let out behind it when fuel is burnt inside. Most of the modem rockets use liquid fuel such as liquid hydrogen, which is burnt with liquid oxygen in order to produce combustion and thrust.

Rockets are launched into space from launch sites of space centre. Kennedy Space Centre in Florida, USA and Indian Space Research Organisation is-one of the important space centres of the world. Each space centre has technical and control areas. It even has a launch pad. Once all the preparations are done, rocket is mounted on the launch pad and it is ready for the lift-off. If the launch site is nearer to the equator, it proves to be more helpful for the rocket’s lift-off. This is because; the spin of the Earth is much faster at the equator.

A rocket has to take up a speed of around 40,000 kilometers in order to move out of the Earth’s gravitational pull. This speed is known as ‘Escape Velocity’. Rockets are termed as multi stage rockets because they do not carry their fuel in one tank. Several separate containers carry their fuel. They are known as ‘Stages’. Once a stage is empty, it is made to drop off. This helps in reducing the load that is being carried by the rocket. Fuel from next stage is then used. The best example of multistage rocket was the American Saturn V. It was the world’s tallest rocket, which carried 3000 tons of fuel.

The three stages Saturn V launched the crew of Apollo to the moon. On 16 July 1969, Saturn V left Apollo XI from Florida, USA. On 21st July, American astronaut, Neel Armstrong stepped on the surface of the moon. As soon as he stepped on lunar soil of the moon, he uttered the words, “One small step for man, but one giant leap for humankind’
