Frontier fleet is like Island 1 connected with several Island to form one gigantic "archipelago" colony . I also wondered about which island is used for heavy factory (manufacturing ships and VF). And I also noticed that the day/night cycle is still controlled by Island 1 dome, so I wonder if this is also for the rest of the island or they have a dedicated day/night cycle system.
Another question:
This is about colony ships, in UC Gundam the colony is using mirror reflection to "power" the colony life, giving day/night cycle, the sunlight is also crucial for the solar energy needed for life cycle. In Macross universe, we see that day/night cycle is controlled by the colony dome holographic projector including producing a holographic sun, the question is whether the system also capable of generating solar power as well?
Now I need to excuse myself, need to dig up several grave for the catgirls that I just slaughtered
