Artificial satellites are used to study the Earth, other planets, to help us communicate, and even to observe the distant Universe. Satellites can even have people in them, like the International Space Station and the Space Shuttle. The first artificial satellite was the Soviet Sputnik 1 mission, launched in 1957. Since then, dozens of countries have launched satellites, with more than 3,000 currently operating spacecraft going around the Earth.
Effect of the telescope on science. Galileo was not the first to use the telescope for observing the heavens, but he was the first to do so methodically. His first methodical observation was of the earth's nearest celestial body-the moon.ithin two months, Galileo completed the task of building the first astronomical telescope. Like the Dutch artisans, Galileo also used his knowledge of lenses and a process of trial and error in order to improve his telescope. He had no sound scientific theory to go on.
