S.T.E.P. is currently a tier 2 tech demo where the AI navigates through procedurally generated star systems.
The procedural generation includes: Star types / sizes, planet types / sizes / distances, number of moons, planet and star field textures.
It's not really scientifically accurate, but that isn't really my focus at this point.
I've includes some screenshots and the application download is also available here.
I'm not really sure if this will evolve into an actual game, but it might well do so.
Sit back, relax and enjoy!
