I like it a lot. Love the names. Guess the font could be a bit bigger for my tastes but that's about my only possible critique.

I think there's no problem at all with the colony ships showing up. Not sure how big they'd be at this scale but you could take them slightly smaller if that'd help the realism. If you're concerned about it you *could* make them dots and do little insets that were essentially satellite zoom-ins of the sites. That might be cool, actually, because you could put stats about each of the drop sites right there.

Nice map. Repped. [edit: Guess not. Have to spread some around first. [/edit]
