In 1957, the Soviet Union launched Sputnik, the first man-made satellite. In 1958, the United States followed with Explorer 1.

Today, there are more than 1,000 of these large satellites revolving around the Earth sending radio signals back to us, which get converted into pictures of the oceans, weather forecasts and even DISH TV.

Many of these satellites are the size of a 7,000-pound hippo and can take decades to design and build.
