Image source Opinion: Paul Watt i would think the thing to do would be to build space stations here and send them out first as automated flight,and set them at different intervals,while they are in flight you will need to start building space ships most likely nuclear power of some sort,but real space ships that once launched from earth they stay in space,to go from space station to space station,then as the space stations reach thier programmed location then you will need some type of artificial gravity or alot of mag boots,then you will need to start your on base food growth,whether it is traditional greens or high protein algae you have to have a sustainable food supply on every space station.
