After the launching of the first artificial satellite, Sputnik-1 by the erstwhile USSR in 1957, thousands of satellites have been launched into space. So far, both Russia and the USA have launched over a thousand satellites each. Other countries like Canada, China, England, France, Germany, India and Italy have also launched their own satellites, including geostationary ones. These satellites have yielded extremely useful information regarding space and the earth. Many space probes going near or around planets have also sent photographs and useful information about planets and their satellites.

In August, 1989, the US space probe 'Voyager' transmitted very clear pictures of Neptune. These pictures showed six moons around Neptune, which was earlier believed to have only two moons.

In October, 1997, the Saturn space probe Cassini (USA) was launched from Cape Canaveral air station in Florida. This probe will study various aspects of Saturn.

Artificial satellites have a wide range of applications in astronomy, meteorology, oceanography, earth resource study, communications and, of course spying.
