Rockets

I will be attending a science fair in my school. I have been given the topic 'Rocket'. So here's a piece of information on this topic, I thought of sharing it with you. Hope you enjoy reading!!
ROCKETS

A rocket is a vehicle, missile or aircraft which obtains thrust by the reaction to the ejection of fast moving fluid from within a rocket engine. The name Rocket comes from the Italian Rocchetta (i.e. little fuse ), a name of a small firecracker. They are basically divided into two parts: a solid fueled rocket motor and the payload. The payload is the section which carries the instruments to conduct the experiment and send the data back to Earth.

The history of rockets goes back to at least the 13th century. The earliest rockets were used for fireworks. By the 20th century it included human spaceflight to the Moon, and in the 21st century rockets have enabled commercial space tourism.

They very lightweight, enormously powerful and can achieve extremely high speeds. Some types of rockets are: Missiles, sounding rockets, launcher rockets, thruster rockets, chemical rockets, etc.

Chemical rockets operate by expanding hot exhaust gas made from propellant against the inside of a bell nozzle, this generates forces that both accelerate the gas to extremely high speed, as well as, since every action has an equal and opposite reaction, generating a large thrust on the rocket.

Chemical rockets contain a large amount of energy in an easily liberated form, and can be very dangerous, although careful design, testing, construction and use can minimise the risks.

Rockets are used for fireworks and weaponry, as launch vehicles for artificial satellites, and for human spaceflight and exploration of other planets. People use all kinds of rockets for the same basic purpose: to carry objects through air and space. Missiles carry explosive devices to targets, while sounding rockets carry scientific instruments into the upper atmosphere. Launch vehicles boost satellites and other spacecraft into space, and smaller thruster rockets steer or stabilize spacecraft in space.

Sunita Williams

I got an opportunity to meet Sunita Williams and also interviewed her as Kidsfreesouls Kids Reporter. Sunita is very impressive and soft spoken. We met for only a couple of minutes but it seemed as if we know each other since a long time. She is very friendly. Sunita has become my role model and it was a memorable meeting with her.

Here is my interview with Sunita Williams on kidsfreesouls.com - Kids Reporters.
