Help with plotting interplanetary trajectories


Recommended Posts

I would first plot a trajectory straight to Jool, then burn at that maneuver node/periapsis multiple times to raise your apoapsis up to just inside the Mun's orbit. That should make it only about a 1200 m/s burn left to get to Jool. You can do that at the next periapsis. Don't start too early or you will enter the atmosphere. But just keep burning after you pass periapsis, even if it takes a while, until your solar apoapsis is at Jool's orbit. Then you can do course corrections to get a Jool encounter after leaving Kerbin's SOI.

we talked about that,

it would take too long the last orbit takes a month and you miss your window.

FYI

Mun orbit, not Minmus ... that might be about 5-6 hours for the last orbit, and 800 m/s applied with no danger of capture. Break it up, and 400 m/s is applied giving an orbit under 90 minutes, another 400 for the 5-6 hours, then a final burn with less needing to be applied. Oh, and usually, you can get a pretty good gauge by watching your plotted and actual SoI change times at the end instead of the delta-v numbers.

That's why I said just inside the Mun's orbit. That orbit will only take a few hours and will be less than 200 m/s off from Kerbin escape.
