Would it really be all that expensive though. We are going to have to send tons of mass out there eventually. Is there anything fundamentally different about a lunar orbit that would make such a base not as useful. I understand it was not designed to experience large acceleration forces but could we not use this as an opportunity to test ion drives and&#x2F;or other low impulse drive mechanism? Slowly inch it towards a linear orbit? Then send astronauts to meet it in orbit with a next gen reusable lunar lander? On a SpaceX heavy and or SLS?
