Introduction

This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book is concerned with the development of models, methods, and algorithms for designing multi-purpose spacecraft missions in the Solar System. It deals with the problems of mathematical modeling of the spacecraft flight trajectories in the Solar System using gravity assist maneuvers, describing their dynamic scheme, and assessing the efficiency of such maneuvers. The book considers methods for a preliminary analysis of possible multi-purpose paths. It also presents a generalized algorithm for constructing isolines. The book also deals with problems of applying the developed methods and algorithms to a wide range of practical problems in multi-purpose mission analysis in the Solar System. It provides the methods and algorithms for a more detailed examination of the basic trajectories, taking into account the length of powered flight segments, and motion of the planets while the gravity assist maneuvers are being performed.
