Gr 5-8 From Telstar, the first commercial communications satellite, to the Tracking and Data Relay Satellite, a nearly 6-ton giant to be launched by the Space Shuttle, this book thoroughly covers the 30-year history of communication satellites. Herda provides statistics on the shape, size, capabilities, and orbital path for several classes of satellites. The author also describes how these satellites are eliminating geographic distances as a barrier to communications. Herda delves into the social implications of beaming news information, propaganda, and television programs around the world and devotes a chapter to American and Soviet military communication satellites. Black-and-white photographs or line drawingsaccurate but not flashydescribe many of the satellites. The book is an excellent and well-researched introduction to the subject. Unfortunately, because there is no chapter on the physics of orbiting satellites, the text occasionally stumbles over terms like three-axis-stabilized satellites or despun horn antenna , which are poorly defined or not defined at all. Two useful appendixes list all the U. S. launched satellites through 1985. Alan Newman, Johns Hopkins Univ . , Baltimore
