History of Space Rockets

Space travel has always been a fascination for humans. Even in ancient times, people dreamt of travelling to the stars. The first recorded attempt at space travel was made by a Chinese scientist named Wan Hu. He attempted to use a chair with rockets attached to it to fly into space, but he didn’t make it very far and died in the process.

It wasn’t until the early 20th century that space travel began to be taken seriously as a means of exploring the universe. In 1903, Russian physicist Konstantin Tsiolkovsky published a paper called “The Exploration of Cosmic Space by Means of Reaction Devices”. This paper outlined the basic principles of space travel using rockets.

In 1957, the Soviet Union launched Sputnik 1 into space. This was the first man-made satellite to be put into Earth’s orbit and demonstrated that rockets could be used for more than just fireworks. It was after this point that space travel began to gain more steam as a serious area of scientific exploration.

The next major step towards achieving human space travel was made in 1959 when the Soviet Union sent two dogs on board Sputnik 9. These dogs became the first living creatures to orbit the Earth. Their journey proved that life could survive in outer space and established rocketry as a valid means of transport through the atmosphere and into outer space. The United States followed suit by sending many monkeys, mice, fish, cats, and dogs into suborbital flights during their Project Mercury, but it wasn’t until 1961 that they succeeded in sending a human man into space.

What is a Space Rocket?

A space rocket is a vehicle capable of transporting material and people beyond the Earth’s atmosphere. Rockets work by propelling themselves forward with thrust generated by hot gases released from the rear of the rocket engine. They are powered by chemical reactions so they do not need an extensive supply of oxygen like spacecraft that use solar power. The first person to ever use rockets as means of transport was Jules Verne, the French writer who wrote “From Earth to Moon” and “Around the World in 80 days”. In his stories, he used gunpowder or copper tubes filled with hydrogen gas as their source for propulsion.

The first rockets were created over 2000 years ago in China and they were used to scare enemies. Chinese astronomers also built up to 200 bamboo towers with copper pipes filled with gunpowder at the top, but instead of using them as weapons, they would ignite the powder so that it could shoot sparks into the night sky. The sound produced by the explosions was said to frighten away evil spirits.

Types of Space Rockets

1. Liquid-fueled Rocket Engines:

This type of engine uses liquid propellants (a fuel that produces gas when burned) which are then ignited in an enclosed space to produce thrust that moves a rocket through space. Sometimes these engines require two or more propellants that are mixed together for added thrust.

Solid-fueled Rocket Engines:

These engines, as the name suggests, use a solid fuel source that is burned to create the thrust needed to propel a rocket. This type of engine is popular because it requires little maintenance and can be stored in a standby position for long periods of time before being used.

Hybrid Rockets:

Although there are several varieties of this type of rocket engine, they all work by using both liquid propellants and solid propellants at different stages during takeoff or throughout space travel. The liquids may be ignited by either pressure or an electrical charge system that activates the entire launch sequence upon ignition.

How they work

A space rocket works by lifting off the ground and shooting into space by using fuel. Rocket engines are powered by chemical reactions to create thrust.

When the rocket engines burn, they use one kind of fuel. That fuel burns right at the stop and sends hot gas down a pipe called the nozzle, to push against the side of the rocket. The faster you need to get away from Earth (the deeper into space you want to go), or if you are carrying very heavy things like astronauts or equipment, then it takes more powerful engines and more fuel.
