| Abstract: |
| A patched-conic technique is used to formulate the mathematical model and to make an explicit analysis of the normal-impact transfer trajcctory to the moon. Some approximations are required in order to obtain the analytical solutions of the normal-impact transfer trajectory to the moon. It is a practical engineering method for preliminary trajectory designing. |
