the primary satellite tv for pc turned into used for astronomical functions. Sputnik 1, the primary artificial satellite tv for pc, has been launched to gather and send crucial records via radio alerts about the situation of the earth’s surroundings, the ionosphere, and the earth’s orbital modifications. presently, astronomical satellites are used to seize pix outside the earth’s floor the use of one of a kind sensors like x-rays, gamma rays, infrared, and ultraviolet.
