Now a second edition is available for those who want to know why astronauts are weightless, why satellites don't fall from the sky, how we will live on Mars, and whether or not there is life elsewhere
in the universe. This book is updated with the latest information on the science and technology involved in the new frontier of space. It is written as a textbook for an undergraduate liberal arts course, with or
without mathematics. Subjects covered include the Shuttle, the structure of the Sun, various orbits and their uses, international space activities, and astronomy from space. Added to this edition, you will find new and
revised illustrations, many of them in color.
