Path: Missions/LunarLanding
% Generates the lunar landing trajectory
With action 'initialize' it creates an optimal trajectory from the
start time to termination. It automatically selects the start time.
jD must be less thatn d.jDTarget. If not, it returns an error.
Type LunarTrajectoryControl for a demo for a polar landing
