Satellites: Exploring Space and Enhancing Communication

Satellites are artificial objects placed in Earth's orbit for various purposes, including communication, navigation, and observation. Initially a concept by Isaac Newton, the first artificial satellite, Sputnik 1, was launched by the Soviet Union in 1957. Since then, thousands of satellites have been launched, serving military, scientific, and commercial purposes. Satellites are equipped with structural subsystems, solar panels, and monitors for data transmission. They are categorized into types like reconnaissance, astronomical, navigational, and communication satellites, each serving specific functions such as intelligence gathering, space observation, geospatial positioning, and telecommunication.
