"Impulsive velocity increment ([delta] V) requirements for one-way trajectories from low-Earth orbit to the major planets are presented in the form of contour charts and tables. The given Earth-to-planet data also apply to return transfers, thereby permitting round trips to be analyzed. The charts relate propulsive effort to departure and arrival dates, travel times, and planetary configurations; they are designed for rapid identification of efficient mission trajectories. The tabular presentation includes hyperbolic speeds and a summary of orbit elements and geometry."--Page [1]
