Epic work, it's always fascinates me when author explores the topic so deep, that doesn't know where to begin, so finally starts with the whole history of the universe or the existence of human race.

I was trying to discuss how it can be done

I don't think there are any serious technical issues that would necessitate inventing something major -- all you need is a lot of engineering. The actual problem is in finding a big pile of money and that, to a large degree, is a function of "What will we get out of it?". The usual answer "But it sooooo cool!" isn't very convincing.

If I understand correctly, a round trip mission (land, plant a flag, pick up some rocks, take pictures and return) is currently technologically feasible. It's pretty much a matter of scaling up Saturn V / Apollo. The main technical issue is cancer risk from radiation, but I suppose that even if that was ignored there would be no difficulties finding astronauts who would be willing to fly.

A colony that doesn't depend on frequent supply launches, on the other hand, seems beyond current technology.
