Interplanetary missions were analyzed that utilize the gravity-assist orbital transfer technique to increase mission capabilities. This swingby maneuver provides a nonpropulsive change in the spacecraft's heliocentric energy which can reduce the amount of propellant needed to complete an interplanetary mission. For certain planetary orientations, incorporating a propulsive manuever at the periapsis of the swingby trajectory decreases the mission's propellant requirement. This decrease results in a reduced initial vehicle mass in low-earth orbit. This study analyzed the feasibility of using a three-dimensional powered swingby to reduce the initial vehicle size for an excursion class mission during the 2010-2025 time frame.
