Spacecrafts Presentation

The document provides information about rockets including when they were invented, how they are used to launch things into space, how rocket engines work using Newton's third law of motion, the parts of a rocket including the frame, skin, fuel, engine and payload, common materials used such as aluminum, titanium, silica and carbon composites, and encourages the reader to make their own model rocket. It discusses the history of rockets from their use in China in the 1200s for fireworks and warfare to the modern Saturn V rocket that launched astronauts to the moon in 1969.

If you had your
very own
rocket, where is
the first place
you would like
to visit?
When Were
Rockets
Invented?
The first rockets we know about were used in China in
the 1200s. These solid rockets were used for fireworks.
Armies also used them in wars. In the next 700 years,
people made bigger and better solid rockets. Many of
these were used for wars too. In 1969, the United States
launched the first men to land on the moon using a
Saturn V rocket.

How do we launch
things into space?
The Short Answer:
We launch things into space by putting them on rockets with enough fuel — called
propellant — to boost them above most of Earth’s atmosphere. Once a rocket reaches
the right distance from Earth, it releases the satellite or spacecraft.

We launch satellites and spacecraft into space by putting them on rockets carrying
tons of propellants. The propellants give the rocket enough energy to boost away
from Earth’s surface. Because of the pull of Earth’s gravity, largest, heaviest
spacecraft need the biggest rockets and the most propellent.
How Does a Rocket
Engine Work?
Like most engines, rockets burn fuel. Most rocket
engines turn the fuel into hot gas. The engine
pushes the gas out its back, making the rocket
move forward.

There are two main types of rocket engines. Some


rockets use liquid fuel. Other rockets use solid fuels.

On the side of the space shuttle are two white solid


rocket boosters. They use solid fuels. Fireworks and
model rockets also fly using solid fuels.
Why Does a Rocket
Work?
In space, an engine has nothing to push against. So how do rockets
move there? Rockets work by a scientific rule called Newton's third
law of motion. English scientist Sir Isaac Newton listed three Laws of
Motion. He did this more than 300 years ago. His third law says that
for every action, there is an equal and opposite reaction. The rocket
pushes on its exhaust. The exhaust pushes the rocket, too. The
rocket pushes the exhaust backward. The exhaust makes the rocket
move forward.
what are the parts of a
rocket?
A rocket has different parts, such as the frame, the skin,
the fuel, the engine, and the payload. The frame is the
structure that holds everything together. The skin is the
outer layer that protects the rocket from heat and air
resistance. The fuel is the material that burns and releases
gas. The engine is the part that ignites the fuel and directs
the gas out of a nozzle. The payload is the cargo or mission
equipment that the rocket carries
what materials make up a rocket?
The materials used to make a rocket depend on the type
and purpose of the rocket, but some common materials are:
Aluminum or titanium for the main frame, as they are
strong and lightweight
Silica or carbon composites for the heat shield, as they
can withstand high temperatures
Liquid or solid propellants for the fuel, as they provide
thrust and can be stored easily
Cardboard, balsa wood, or plastic for the model rockets,
as they are cheap and light

rocket!
