During the three centuries between the work of Kepler and Newton and the launching of Sputnik, mathematicians developed sophisticated methods of predicting the natural movement of celestial bodies in our Solar system. Battin's textbook includes this rich history in a foundation of mathematical essentials on which he clearly and logically constructs the theories of astrodynamics and space navigation that eventually led to space exploration. The complete explanations for each concept presented eliminate the need for additional references, and the chapters' independence allows them to be taught in any order, at various levels.
