For kids who love to explore outer space, learning about rockets is definitely a must. In this article, we will share some cool rocket facts that will fascinate anyone who loves space!

History Of Rockets

The first rockets were developed in the third century BCE by Chinese alchemists who wanted to create an elixir for immortality. The earliest known rocket was made from bamboo shoots filled with gunpowder and used as fireworks during celebrations.

Simpler fireworks were used to launch the first rocket into the air. In China, over 800 years ago, in 1232, the first fireworks were made. They were the first rocket made for entertainment and celebrations.

Rockets were enhanced in the 1700s by using metal in their construction.

Many battles in the 1800s and 1900s, particularly the Second World War (1939–45), utilized rockets as weapons.

Konstantin E. Tsiolkovsky, a Russian scientist, had the concept that rockets may be utilized to fly into space.

He didn't invent any rockets, but his theories on the subject were helpful.

In 1804, William Congreve invented a new type of military weapon called the 'Congreve Rocket' which could travel over 2 mi (3.2 km) into enemy territory before exploding upon impact or being shot down by the anti-aircraft fire.

In 1925, a U.S. engineer named Robert H. Goddard created the first rocket which was a liquid-fuel rocket.

Sputnik 1, the first spacecraft, was sent into orbit around Earth by the Soviet Union using a rocket in October 1957.

Types Of Rockets

Today there are three main types of rocket engines: solid propellant, liquid fuel, and hybrid combustible rocket engines that combine both fuels together.

Solid propellant comes in various shapes sizes depending on what they are designed to carry while liquid fuel may come in either a cryogenic state or as a high-pressure gas.

Liquid-fueled rockets are typically used for outer space travel since they can be refueled in orbit if needed.

The ion rocket fires a stream of xenon ions that have had their negative electrons taken by the rocket's electron.

The Variable Specific Impulse Magnetoplasma Rocket (VASIMR) is a newer form of a rocket in research that works by accelerating plasma created by extracting negative electrons from hydrogen in a magnetic field and releasing them out of the engine.

Working Of Rockets

Rockets are devices that generate the necessary force, push, to propel anything forward. A rocket takes off by creating thrust.

They work by burning a combination of two fuels: an oxidizer and a fuel.

Rockets can reach speeds of up to 17,000 mph (27,358.8 kph)!

The oxidizer provides the oxygen necessary to burn the fuel and create thrust. Without it, the rocket wouldn't be able to go anywhere.

Fuel makes the engine work once it is burned within a chamber. When the fuel is combined with oxygen and set on fire, it burns. As the fuel burns, it produces hot gas, which escapes via a hole in the back of the chamber.

The rocket is propelled forward by the force of the gas traveling rearward. Jet propulsion is the term for this action.

Jet propulsion is also used in the engines of jet airplanes. Rockets, unlike the jet engine, have their own air supply.

This makes rockets useful in space, where the air is limited.

Fun Facts About Rockets

Did you know that rocket launches are very loud? They can be heard for miles around! Plus, they produce a lot of smoke and flames. This is all part of the launch process, which helps to power the rocket into space. Here are some fun rocket facts.

Rockets were most likely invented in the 1200s by the Chinese. They created rocket engines by putting gunpowder in wood casings.

The word 'rocket' comes from the Italian word 'Rochette', which means 'little spindle.'.

The first rocket was launched in 1926 after being designed by Robert H. Goddard, the man regarded as the pioneer of modern rocket science.

In the 1200s, the first rockets were used to shoot fireworks.

A rocket engine can also go underwater with special equipment.

Yuri Gagarin was a Soviet astronaut who became the first human to go into outer space on April 12, 1961. He was a part of the Soviet Union's R-7 rocket launch vehicles.

When a rocket's propellant is ignited, it produces hot gas, which exits through the exhaust port at the back of the rocket.

Rev William Leitch was the first to suggest using a rocket to propel a human into space in 1861.

Over 200 piloted rockets have been launched by NASA for space missions.

The Saturn I, IB, and Saturn V were the first rockets manufactured by NASA to launch astronauts.

The Saturn V rocket is not only the most powerful, but it is also the most successful, with 13 successful launches.

Two Saturn V rockets from the Apollo missions are still floating about in space. They're still being tracked by NASA as Near-Earth Objects.

Scientists began to speculate about the ability of rockets to travel into space because they are built to fly swiftly forward and upward. This concept became known as rocket science.

In June 1944, a Nazi Germany V-2 rocket became the first to reach space.

The Space Launch System, developed by NASA, are the most powerful rocket systems ever created.

The Apollo missions were the first to send men to the moon.

The Skylab space station was launched by a Saturn V.

Rocket engines power space shuttles.

Satellites are launched by NASA using rockets.

Rockets are also used to send space probes to distant worlds.

On February 12, 1961, the Soviet Union Molniya 8K78 rocket became the first to launch a spaceship that passed by another planet in the solar system.

On April 12, 1961, the Soviet Union's Vostok-K 8K72K rocket became the first to launch a human into space.

A rocket vehicle must travel at rates of 11200 mi/s (11.2 km/s,) to break through Earth's gravity.

In April 1961, the first human ventured into space aboard a massive rocket. He completed a 108-minute round!

The Soviet Union Sputnik 8K71PS is the first rocket to launch a living dog named Laika into space for the first time on November 3, 1957.

On January 31, 1966, the Soviet Union Molniya-M 8K78M rocket became the first rocket to launch a spacecraft that endured its landing on a large planet in our Solar System.

Since the NASA space shuttle program ended in 2011, humans have traveled to the International Space Station in a Russian Soyuz capsule.

A key component of aerospace engineering is rocket science.

A rocket, but not a jet engine, may fly in space's vacuum, which is devoid of air. A jet plane has a ceiling limit over which it cannot fly due to a lack of air supply.

Rockets use the exhaust off their engines to propel them forward.

Humans and equipment can be sent into space using rockets.

The military can employ rockets to deliver bombs over short and large distances.

Today, new rockets are being developed. Future missions will include astronauts. The new rockets will not resemble the space shuttle in appearance.
