Arriving At A Planet When It's At A Node?


Recommended Posts

Hi Guys!

I haven't played Kerbal in ages, but watching a few videos on YouTube suddenly got me interested again.

On one of my new missions, I built a small probe and just blasted it out of the Kerbin system, until its fuel ran out.  As luck would have it - and it really was luck - it arrived perfectly at Duna, just as the planet was at its descending node.  OK, not a big deal I agree, but still an interesting little fluke nonetheless.

This got me thinking, would it be possible to arrive at other planets which have a more costly inclination to correct, in the same way.  Moho for example, if the transfer was timed right, arriving when it was at a node, could save a tanker load of fuel.  I know Eve can be used to sort out that inclination, but I'm not particularly good at working our gravity assists and much prefer the more direct method.

So, is there any way to figure out when to make a transfer burn to another planet, so the space craft reaches it when it's at one of the two nodes?

Thanks everyone.
