Oracle IAS, the best coaching institute for UPSC/IAS/PCS preparation in Dehradun brings to you UKPCS Science (paper #6).

A satellite is an object that orbits another object. In space, satellites may be made by man, or they may be natural. The moon is a natural satellite that orbits the Earth. Most man-made satellites (artificial) also orbit the Earth, but some orbit other planets, such as Saturn, Venus or Mars, or the moon.


Satellites are launched into space by various types of rockets, called launch vehicles. A single launch vehicle can be used to place two or more satellites into orbit at one time. Some launch vehicles are expendable they are designed to be used only once. The space shuttle, a type of manned spacecraft, serves as a reusable launch vehicle. A few satellites have been launched from high-flying airplanes.
