If you haven't already tried it, you should look into playing the game Kerbal Space Program.

Playing this game gives you a real appreciation of the complexities of navigating in space.

Recently, China achieved a feat of astronavigation by placing a satellite into the Earth-Moon L2 halo orbit.

This interesting satellite is what allows China to conduct scientific missions and keep communications with their rover on the back side of the Moon (which is in a tidally-locked orbit with Earth).

I can only imagine the complexities which were required to achieve this orbit!  Unfortunately, Kerbal Space Program does not support simulating the physics of this orbit.
