ABSTRACT

A mission plan for a Small Lunar Polar Orbiter, or SLPO, is presented. The mission is planned for August of 1995. The method used to compute the mission trajectories is discussed at length. The mission plan includes a full description of the trajectories involved in the mission, including the delta-V maneuvers required to accomplish the mission. The delta-V requirements for the mission were found to correspond with the delta-Vs of the Apollo missions. The mission plan also includes mission timelines and launch windows, selection of a launch vehicle and upper stage, and mass breakdowns for the vehicle. It was found that the relatively inexpensive Delta II/6925 booster with its PAM-D upper stage was able to place the 800 kg spacecraft into the lunar transfer orbit. The mission plan was carried out while placing a high priority on minimizing the costs and risks of the mission.
