It's only rocket science : an introduction in plain English /

The term "rocket science" implies that one needs a very sophisticated level of technological and scientific knowledge to understand the principles of this field. However, Rogers (Isle of Wight, UK) attempts to explain these seemingly complex phenomena in relatively simple terms, i.e., without reference to mathematics. The introduction considers basic definitions of space, gravity, propulsion, and orbits, and presents the concept that the definition of space is flexible. Other chapters consider in detail diverse topics such as spacecraft, space missions, movement in three dimensions, propulsion systems, communications satellites, humans in space, and future prospects. Some potential developments in the last area are space elevators, nuclear propulsion systems, and space tethers. Rogers does a good job in explaining these topics in accessible language. The chapters include line drawings and half-tone and color photographs; technical appendixes and a glossary augment the text. Summing Up: Recommended. General readers. J. Z. Kiss Miami University
