Wanted: Slingshot Window

[RSWingman]

I've seen all kinds of crazy slings, many of which take you back toward the Sun or require extra orbits before catching the next Planet out (not too LOX-friendly either). But I don't think I've ever seen any variant VEM in direct succession.

Is it even possible to have a course that departs Earth for or Venus, and once targeting Earth, creating a direct EVJ cascade? Even if a second orbit of Venus is necessary?

Or maybe something like E(Me)VEMJ? Of course, it doesn't matter whether it involves combinations of inside & outside slings like a slalom course.

I'm aware that Cassini used Venus twice, then EJS. But poor Mars is left out .

Any ideas for launch dates?

Where do you want to go? Mars is normally left out because its gravity is not sufficient to make it worth the trouble. flytandem came up with a great "enhanced" Grand Tour here:

It'd be great to hit every planet in a row, but I don't wanna get too greedy... hit every planet and see how much velocity I can build.

I'm sure you can hit them all in a row, its just a question of how much fuel you are prepared to use .
