So basically, step two of getting to Mars is to setup interstellar refulling stations.

Once you get to mars, or any destination, you need fuel to get back/other things...

So assuming we have an engine that can deliver us back and forth in a reasonable time, then we need to think about deploying intermediate refueling drones... and then drones to refill them... and then how to manufacture and deliver that fuel to the various nodes...

And if we are running out of helium, on earth, we need to find the most harvestable noble gas we can in the solar system...

What are the atmospheres of the other planets made up of, specifically Jupiter, how could we slurp off its atmosphere to Bush is around the solar system?

Assuming other energy sources don’t pan out

Interstellar refueling stations don't make any real sense because you spend as much fuel rendezvousing with the refueling station as you'd get back.

Ideally, you find fuel at your destination, or you have to take enough with you to get back. Or you make plans to stay...
