PDF document and a MATLAB script called pprop_lunar that can be used to numerically integrate the geocentric orbital equations of motion of a trajectory from the Earth to the Moon. This scientific simulation begins at a user-defined epoch and geocentric state vector (position and velocity vectors) representing the point of trans-lunar injection (TLI) and ends at (1) closest approach to the Moon, (2) a user-defined Moon-centered (selenocentric) distance, or (3) at a user-defined final epoch.
