How do you get there, I can't even figure out how to be at the right spot.
Make sure you have enough fuel to get into Kerbol (sun's) orbit. Then it's basically orbital rendezvous. So look up tutorials on that.
And I finally landed on Duna.
Quicksaved and screamed at around 200m/s with that rover on the surface. But it's huge, so I didn't get very far (wanted to explore the poles).
My next goals will probably be the innermost planet, then Jool's smallest moon, then Jool.
