Discussion of more advanced concepts in astrodynamics. Includes fundamental theories from celestial mechanics, resonance, dynamical systems theory and numerical methods with application to the motion in multi-body regimes and interplanetary spacecraft under the simultaneous influence of multiple gravitational bodies. Assumes experience with the two-body problem.

Learning Objective:

Introduce students to spacecraft orbital dynamics and the issues associated with orbital design and stationkeeping in regimes where multiple gravitational fields are simultaneously significance. Thus, primary focus is the three body problem and regimes where two-body analysis and conics are not valid models. Numerical methods to support trajectory design including differential corrections strategies. Families of solutions and their stability analysis.
