If you were going to establish a colony on another world, how would you do it? I've read modest estimates of between 150 up to 80,000 colonists sent at one time, to establish it. About 1,000 adult colonists should be enough to begin building the colony, I think. You could establish a central base, then extend 4 outposts (one toward each cardinal direction) toward the horizon, keeping in sight of the central hub and the two adjacent outposts, if possible. (Some terrain features might interpose.) Then, as colonists are born and new colonists arrive, you could expand outwardly from that hub. What do you think?
