Direct ascent

[slenderman666]

Hey all, I was doing a direct ascent to the mun. I was wondering on how i would do a direct interplanetary ascent. Say, like a direct ascent to Duna, or would Jool be easier because of its large SOI? Any tips on how to do this?

I'd say: Wait until you have a transfer window, and then, at the right time of day (¼ of a day - 1.5 hours - after or before midnight, depending on your target) launch and burn until you get in intercept. I'd still try to go to orbit first, for efficiency reasons, but well, if you have enough dV or high enough TWR, there should nothing stop you from going directly.

I'm not sure but shouldn't this question be in Gameplay Questions?

The question with vertical launches is always one of timing (as long as your rocket can actually get you there). The best way to find out the timing is just to do it once and revert. You will miss by a bunch, but you can see how much the destination planet moves along its orbit while you are in transit. Once you know how many degrees ahead of your target you need to aim, then aim and fire at it again.
