I’m looking for a program (preferably free, of course) that I can use to not only simulate orbits, but determine the effects on those orbits of various propulsive maneuvers. This, as might be obvious, if to support Pax Orionis, so I can get the orbital mechanics of maneuvering in Earth-Moon space correct.
Back in my college days I did this sort of thing for fun using paper pencil and calculator. Because what’s more fun than working out how the gears of the universe actually turn, using your own brain? But here I think a computer system would be better purely for the interests of efficiency.
I don’t need anything fancy, just something I can use.
