Technical Memorandum 33-736 - This document is divided into three volumes. Volume I comprises the mission design data for Venus, Volume II the data for Mars, and Volume III the data for Jupiter. This document presents mission design data for direct transfer trajectories from Earth to three planets - Venus, Mars and Jupiter, extending previously published information through the 1990 departure opportunity. The primary purpose of this effort is to provide the mission analyst with graphical information, sufficient for preliminary mission design and evaluation. A specially modified version of the Space Research Conic Program (SPARC) was used to generate the trajectory information presented. The data were automatically contour-plotted on the SC4020 plotter using the General Plot Program (GPP), then hand-retouched and labeled. A special program (VIEWPE) was constructed to provide planetary positional data in graphical form, plotted on the SC4020, and presented in original format. The data are arranged in three sections by arrival planet, in natural sequence. Each section consists of two parts - the trajectory characteristics for all available opportunities to the particular planet, in chronological order, followed by that planet's positional data for every calendar year, from 1975 to 1995.
