PREFACE<br />

The study <strong>of</strong> astrodynamics is becoming a common prerequisite for<br />

any engineer or scientist who expects to be involved in the aerospace<br />

sciences <strong>and</strong> their many applications. While manned travel in<br />

Earth-Moon space is becoming more common, we are also<br />

concentrating on sophisticated applications <strong>of</strong> Earth <strong>and</strong> interplanetary<br />

satellites in the fields <strong>of</strong> communications, navigation, <strong>and</strong> basic<br />

research.<br />

Even the use <strong>of</strong> satellites simply as transport vehicles or platforihs for<br />

experiments requires a fundamental underst<strong>and</strong>ing <strong>of</strong> astrodynamics.<br />

We also recognize that for some time to come the ballistic missile,<br />

whose mechanics <strong>of</strong> flight has its foundation in astrodynamics, will be<br />

a front-line weapon in the arsenals <strong>of</strong> many countries.<br />

Beginning with the first graduating class <strong>of</strong> 1959 the United States<br />

Air Force Academy has been in the forefront <strong>of</strong> astrodynamics<br />

education. Much has been learned from this experience concerning both<br />

the structure <strong>of</strong> the courses <strong>and</strong> what theoretical approaches are best<br />

for teaching the subject. Consequently, this text is particularly<br />

structured for teaching, rather than as an exhaustive treatment <strong>of</strong><br />

astrodynamics.<br />

The astrodynamic theory is presented with brief historical<br />

digressions. Although many classical methods are discussed, the central<br />

emphasis is on the use <strong>of</strong> the universal variable formulation. The<br />

theoretical development is rigorous but yet readable <strong>and</strong> usable. Several<br />

unpublished original derivations are included in the text. Example<br />

problems are used frequently to show the student how the theory can<br />

be applied. Exercises at the end <strong>of</strong> each chapter include derivations <strong>and</strong><br />

quantitative <strong>and</strong> qualitative problems. Their difficulty ranges from<br />

straightforward to difficult. Difficult problems are marked with an<br />
