Advanced orbit planning - efficient slingshot intercepts without calculating timings

[allmhuran]

After some of my previous videos I was asked several times - "When I do a gravity slingshot to get somewhere, how do I time things right to make sure I hit my second target?".

Well, you can do this the way NASA does it if you like, which means getting out the calculator and waiting for perfect launch windows. But you can actually get intercepts whenever you like quite efficiently with just a bit of patience - actually, the amount of patience you need is proportional to the amount of efficiency you want - using the technique I demonstrate in this video (and other similar techniques).
