I thought I’d annoy people with that comment.<br />For the record, even when not taking into account the distances, Mars is more habitably then Callisto. But beyond mars and moon the Gallian satellites are the next most likely destination. Energy to heat and power the settlement could come from fusion power, by the time we get that far out I suspect fusion technology would have been perfected. But perhaps Ganymede would be better, more rocks and metals and gravity to work with.<br />
