The milestone that

The milestone that changed the world Russian Russian satellite Sputnik 1. Sputnik's radio signal. The Soviet Union from the Baikonur Cosmodrome launched the first artificial satellite of humanity, on 4 October 1957, thus marking a before and after the space race, making the Soviet Union, led by Russia, U.S. overtaking in the race. This program was called Sputnik, which when successfully placed in orbit, radio signals delivered in the form of beeps, demonstrating the success of Soviet scientists. This program was followed by Russian successes, such as programs Sputnik 2 and 3. Note that in the Sputnik 2, the Soviet Union managed to place in orbit the first animal in history, the dog named Laika, which he originally was called "Kudryavka" (Russian: ) but decided to change his name to it easier to recall in history.With Sputnik, the Soviet Union inadvertently caused a collective psychosis in the United States due to fears in the U.S. population led to the breakthrough technology developed by the Soviets. In 1960 he launched the first communications satellite: the satellite Echo I was a person who was not equipped with a two-way system, but functioned as a reflector. In 1962 he launched the first active communications satellite, Telstar I, creating the first international television link. The Space Surveillance Network (SSN) has been tracking space objects since 1957, following the launch of Sputnik I. Connie Milstein Since then, the SSN has logged more than 26,000 objects orbiting the earth and keeps your crawl on some 8,000 man-made objects. The rest fall back into the atmosphere where it disintegrates or if they resist, strike the Earth. Objects can weigh from several tons, as rocket stages, until only a few kilograms.About 7 of space objects are operational (about 560 satellites) while the rest is space junk. It mentions a replica identical, developed in Russia, the famous Sputnik is located in the main lobby of the United Nations building in New York City as a symbol of technological development achieved by man.
