What is Satellite?
A satellite is any object that orbits something else. The Earth orbit the sun. There are hundreds of satellites in operation. They are used for diverse purposes such as weather, forecasting, television signal, radio and internet communications. And the Global Positioning system.
They are also used to look outward to the solar system for research and data gathering purposes.
How Does Satellite Work?
A satellite is basically a self-contained communications system with the ability to receive signals from Earth and to retransmit those signals back with the use of a transponder an integrated receiver and transmitter of radio signals.
Why are Satellite important?
The Birds eye view that satellites have allows them to see large areas of Earth at one time. This ability means satellites can collect more data, more quickly, than instruments on the ground. Satellites also can see into space better than telescope at Earth surface.
How does NASA Use Satellites Today?
NASA satellites help scientists study Earth and space. Satellites looking toward Earth provide information about clouds, oceans, land and ice.
They also measure gases in the information, such as ozone and carbon dioxide, and the amount of energy the earth absorbs and emits. All these information help scientists.
The Tourism Satellite Account?
