Reasons to not put off shit to the last moment. I'd say Google it.

I meant time constraints as in the theoretical mission time, not time to do the project. I have plenty of time to do the project. And I have googled it, but as per my original post, I could not find any that did more than a simple Hohmann transfer.

Maybe something here or as starting place?

Then it's probably a trade secret, you should use what has been confirmed is fine. Not a reasoning for your OCD to kick in for. It is just a theoretical entry. Anything we build will be destroyed in jupiter/saturn atmosphere anyways.

In the bad old days (early 90s) I used a patched conic solver.

I wager that there are tools to do that kicking around.

More Matlab (just adjust Mars till Saturn)

etc.

And there are half a dozen antique TDs about FORTRAN codes kicking around on the NASA TRS.

Not “OCD” but mission time constraints based on his project. If you can’t help, instead of being flippant or dismissive, don’t comment.

You need to solve "Lambert's problem":

The inputs will be Earth's position at some time t0, the time of flight ToF, and Saturn's position at time tf=t0+ToF.
