Ok, so the plan in the broadest sense: establish a “colony” in orbit around Jool’s moon, Laythe.
Great. Now, can we focus that a bit? Maybe a list of specific objectives?
Objective one: a base of operations (including resources such as fuel, electricity, habitation, etc.) in orbit around Laythe.
Objective two: a fleet of utility craft, usable in the Jool system for various scientific/utilitarian/recreational purposes (landers, tugs, probes, etc.).
Objective three: establish a presence around Laythe sufficient to explore the rest of the Jool system (Vall, Tylo, Bop, Pol).
Groovy. Of course, each of these objectives is much more complicated than I’d like. In fact, each is rife with problems I gave no thought to before launching my brave Kerbonauts into the heavens.
M’eh. I’m sure it will be fine.
