Speech Title:
Low Thrust Trajectory Optimization in Cislunar Space
Abstract:
Hamiltonian methods are used to study the planar circular restricted three-body problem. The use of the Birkhoff normal form is extended to the case of the spacecraft dynamics subject to continuous thrusting. The normal form method produces local orbital elements, namely the canonical action-angle variables. The analog of Gauss's variational equations is developed and combined with Lyapunov methods to produce low thrust orbital transfers. The examples treated are transfers in the vicinity of the L5 Lagrangian point of the Earth-Moon system.
