A satellite is a small object travelling around something bigger. The Moon is a natural satellite of Earth. A spacecraft launched into orbit around Earth is an artificial satellite. Since Sputnik-1, about 6,000 more satellites have been launched by 40 countries. Learn about how we use satellites every day without knowing it to talk on the telephone, watch television, use the internet, predict the weather, navigate the landscape and run businesses.Specially commissioned cartoon-style illustrations in full colour make these books attractive and accessible even to reluctant readers. Information is conveyed through captions, labels and humorous speech bubbles in addition to the main text. Illustrated sidebars headed `How It Works', `Top Tip' or `You Can Do It' supply more facts, describe simple, safe experiments, or steps that readers can take to help make the world a better place. Each volume includes a timeline and a list of `Did You Know?' facts.
