Kids are surrounded by images and stories of space exploration – in movies, news reports, books, cartoons and games. As the Bergers say in their introduction, "Everything we hear and see about space makes us curious to know more." This book introduces the basics of space travel – how a rocket works, how a satellite stays in orbit, and how a space station is built. It stretches the imagination by providing answers to questions like "Will people ever live in space cities?" and "Where would people live on Mars?"
