Hardcover. Condition: Good. Nora Wertz (Cover Design) (illustrator). [11], 317, [1] pages. Illustrations (most in color). Index. Ex-library with usual library markings. The author was a Space Mission Design Engineer with the NASA Jet Propulsion Laboratory. Without using a single mathematical formula or complicated scientific jargon, this book explores the functions and roles of satellites, the forces and masses fueling rocket science, the logistics of launching a shuttle into space, the stars and planets that comprise the Milky Way, and more. Excerpted from Booklist: Promising to teach orbital mechanics "without the math," Lee, an engineer with the NASA Jet Propulsion Laboratory, delivers the facts space enthusiasts will savor. Lee's purpose is less to impress than to explain the principles of rocket propulsion and how a spacecraft achieves or changes orbit. Verily, interested readers yearn to see a shuttle launch, and, after telling them where to write for tickets, Lee profiles the sequence of countdown events, followed by the major events of maneuvering in flight. The other orbital problem Lee explains is how to get to Mars. Second Edition [stated]. First Printing [stated].
