Satellites

Satellites are used for different types of reasons, for a example navigation, communication, weather, research and many more. They are  used to collect information from another planet in order for communication. There are also different kinds of Satellites like Astronomy Satellites, Atmospheric Studies Satellites, Communication Satellites, Navigation Satellites, Observation Satellites, Space Exploration Satellites, Remote Sensing Satellites, Search and Rescue Satellites and Weather Satellites. Some Satellites are used for important causes for military  and human spacecraft.

Satellites were invented on October 4 1957 when the Soviet Union launched off the first satellite named Sputnik. Sputnik in Russian means fellow traveler or companion. But no one knew  who had invented the first human made object in space. The first two  communication active satellites were  launched in space in 1962 by United States . These two satellites received radio signals from Earth and  increased the signals before re-transferring  them back to Earth. The development of the radio signals were more reliable and long-lasting by unresisting satellites.
