PDF user's manual and MATLAB script named e2m_sweep that can be used to perform a parametric “sweep” of ballistic interplanetary trajectories from a user-defined Earth park orbit to encounter at Mars. The user defines the initial departure calendar date, the sweep duration and the step size to use during the analysis. The software assumes that interplanetary injection occurs impulsively from a circular Earth park orbit. The software also assumes the arrival date of each sweep trajectory is fixed to the value provided by the user. The user can also select either the ascending or descending hyperbolic injection for the sweep.
