hi, what do you think is the best flyby sequence in order to reduce at minimum the ship's weight and cost?

Moho, Eve/gilly, Duna/ike, Dres, Jool Sys, Eeloo, Kerbin Sys?

I may be mistaken, but I was under the impression that the flybys have to be performed in the order stated in the contract.

No. In any order.

Maybe, Eeloo - (Moho - Eve/Gilly - Duna/Ike - Dres) with apocenter around Eeloo - Jool sys. - Kerbin sys.

yea, in any order except the last crash course.
ty for the tip "start from eeloo", I think I will save a lot of fuel, but don't I waste a lot of time with large orbits?
I'd like to find a compromise between carried fuel and time...
maybe eeloo, jool sys, dres, (Moho - Eve/Gilly - Duna/Ike) with apo on dres - kerbin...?

The good thing about hitting Eeloo first is, you can use it as setup to get down to Moho and probably save fuel overall.  I don't think there's going to be much compromise ... and thinking about it, Jool first might be better.  Given all the moons there, you're going to have to CAPTURE, and that's going to be easiest to set up coming direct from Kerbin.

It can be hard to find a good transfer window from Eeloo to Jool. I think, it's better to try Moho second.

[Spricigo]

I'd start with Eve-Moho-Eve. There is quite a saving that can be done with gravity assist(or powered assist) from Eve in that first stage.

I second this.  While there is something to be said for boosting to Eeloo first and then setting up a bi-elliptical transfer to Moho, in the interests of time, tedium, and overall fuel savings, you're better off taking Eve-Moho-Eve first.  Also remember that transfer windows are least frequent between planets that are next to one another in their orbits; it may make more sense to skip around the system a bit.

guys, I've almost completed it.
I've no fuel and i'm here:

as I do not want redo 40y of mission, the question is: if I build another ship in order to capture the pod and land it on kerbin, the contract will be completed anyway?

Get out and push.

 

You should be fine as long as 1)at least a single part was in all the situations 2)Your 'vessel'  is stil "new".  (When to crafts dock together the resulting craft  get the same 'age' as the older one. That is how old the two crafts will be considered after undocking again).

Whatever you do, save first.

Yes.

For these missions, just get a command module (a probe core would do) into all required situations. It doesn't matter how it's moved or if it's docked to different vessels along the way or anything. Just get your pod home and all will be fine.

[antipro]

ty all, i have to clarify that my vessel has no docking port, so I try again some other ninja gravity assist maneuvers then I'll build the rescue ship with the grabbing unit.

[James Kerman]

That close to Kerbin, I would just get out and push.  Great work though.

Yes, just release grabbing unit after correction.
