Artificial satellites are those put into orbit by man. Equipment on a satellite is hardened to survive in the radiation and vacuum of space. Since there is no air in space and therefore no air resistance‚ satellites come in many shapes and sizes. Types of Satellites and their Uses We use satellites for different purposes and all satellites can be placed in one of the following categories: Communications Satellites Distribution of television and audio signals‚ and telephone connections via satellite
