Because of the technical difficulties involved in landing the Flying Castle on smaller bodies, especially icy moons, once we establish ourselves in the Asteroid Belt, we will maintain that orbit.
Smaller expeditions, such as the ones mounted on the surface of Mars, will be dispatched to the outer planet moons.
Such journeys will typically comprise two or more shuttle/thrusters and a fuel/habitat module. Depending on distances and fuel available, such expeditions can last from months to years.
Ah, good - we can also visit Titan!!
Months or years?
I've changed my mind.
I want to stay in the castle.
