Space Exploration (Mission: Science)

People have been fascinated by the sky since ancient times. Perhaps that is why astronomy is thought to be the oldest science. Still, no one knows how big outer space really is. Modern technology has helped people learn more about the universe. Telescopes let people see outer space from their own backyards. And space travel has helped improve the fields of medicine, and computer and environmental science. For more information on outer space, read Astronomers: From Copernicus to Bell Burnell, another book in the Mission: Science series.
