So far, we have seen the arkship landed on Alioth. I think a better place to put the arkship is in geo/aliothstationary orbit with a space elevator hanging down to the safezone. This would allow the game to be more balanced while requiring more delta-v to do space stuff and would be more realistic in general.
And please watch this video to see what I mean. This guy can explain it much better then I can.
