This handbook contains graphical data necessary for the preliminary design of ballistic missions returning from Mars. Contours of Mars-departure energy requirements, as well as many other launch and Earth-arrival parameters, are presented in arrival-date/launch-date space for all departure opportunities from 1992 through 2007. In addition, an extensive companion document is available; it contains Earth-to-Mars graphical data and explains mission design methods, from launch-window development to Mars probe and orbiter arrival design, using the graphical data as well as numerous equations relating various parameters. This document is one of a planned series of mission design handbooks. This publication is one of a series of volumes devoted to interplanetary trajectories of different types. Volume 1 deals with ballistic trajectories. The present publication is Part 5 and describes ballistic Mars-to-Earth return trajectories. Part 3 treated ballistic trajectories to Jupiter. Part 4 described ballistic trajectories to Saturn. Parts 1 and 2 treated ballistic trajectories to Venus and Mars, respectively.
