The modern-day rocket is a workhorse of the space age, and we can thank Tsiolkovsky, Goddard and von Braun for that. Rockets have become the most reliable means of getting into space and paving the way for human exploration. They also give us access to Earth’s upper atmosphere: a region so rich in biodiversity, it was almost named our 10th planet. But what are these vehicles? How do they work? And how can you get one for your very own? We’ve got the answers, so read on! The first section will cover basic rocket science and terminology before diving into different types of rockets and their uses in space exploration.


Basic Rocket Science

Rockets are vehicles that carry a payload into space. They do this by generating thrust, primarily through chemical reactions inside the rocket's combustion chamber. Once the propellant is expelled at high speeds from the bottom of the rocket, it creates a thrust force (or pressure) and expels the vehicle and its payload into space.


The three common types of rocket propulsion systems are:

- Liquid fuel rockets fire a liquid mixture of fuel and oxidizer to produce exhaust gas;

- Solid fuel rockets use solid propellant; and

- Hybrid rockets, which use a solid propellant mixed with a liquid or gaseous oxidizer.


Different Types of Rockets

The first thing to know about rockets is that they can be divided into two categories: those that use liquid fuel and those that use solid fuel.

Liquid Fuel Rockets: These types of rockets require a fuel like kerosene or hydrogen to propel themselves into space, as the chemicals will ignite when they come into contact with oxygen. Liquid fuel rockets are more complicated than solid ones, but they’re also much more effective – and because they’re so reliable, NASA has used them for their Mars missions.

Solid Fuel Rockets: These types of rockets don’t need to use any type of fuel. Instead, they contain a material called an oxidizer because the chemical properties cause it to burn without coming into contact with oxygen. The materials inside these rockets must be compressed before launch, which makes them difficult to transport because you have to pack it in just the right amount. Because of this difficulty, scientists usually use solid-fueled rockets for short flights rather than long ones that require lots of fuel.


Uses of Rockets in Space Exploration

The three types of rockets in use today are liquid-fueled chemical rockets, solid-fueled chemical rockets, and ionized gas thrusters.

Chemical rockets are the most common type. They operate by burning a fuel to produce hot gases which are ejected from the rocket nozzle at high speeds. These rockets are usually not reusable because the fuel is either burned up during ascent or it's too difficult to store on board.

Solid-fueled chemical rockets work similarly but instead of combusting liquid fuel, they feed fuel into solid chunks that burn through their entire supply during launch. These rockets also aren't reusable because there's no way to store the fuel on board.

Ionized gas thrusters work by ejecting charged particles out of a nozzle at high speeds. This type of rocket can be used multiple times because the propellant for this type of rocket is an ionized gas which can be stored onboard.


Conclusion

Rockets are a type of missile, and they launch objects such as satellites, people and other payloads into space. Rockets are the only way to achieve orbit, and there are many different types of rockets that can be used for different purposes.

Rockets can be classified as either expendable or reusable. Expendable rockets, such as the space shuttle and the Saturn V, are used only once and then they are disposed of. Reusable rockets, such as the Delta IV and the Falcon 9, can be flown again and again.

Different types of rockets include:

- Hydrogen-powered rockets: these are the most common type of rocket, as they’re efficient and relatively cheap to produce

- Ion propulsion: these require a lot of power, but can reach speeds up to 10 times faster than those of standard chemical rockets

- Chemical propulsion: these use a propellant that is stored in a tank and then fed into a combustion chamber where it is mixed with a liquid or solid oxidizer

- Electric propulsion: this type of rocket does not need any fuel because it is powered by electric thrusters.

- Solid propellant thrusters: these use a solid fuel

- Liquid propellant thrusters: these use a
