OK, that's funny.
Every time the decommissioning of the ISS has come up online in the past decade or two, there has been someone to suggest – why not
simply move it to the moon instead? Of course, the idea is just
ridiculous, because that would be more than half the delta-V cost of launching half of a new ISS, and in many ways it does not compute.
But, see, uh, I'm not ignorant of that, but I always felt that... there had to be a way to avoid the complete destruction of a piece of space history, and prolong its life, making the ridiculous person sound like the more sensible. And the reason it pained me more – I thought in the future space will become easier, a hundred years from now, I'm thinking, they'd simply launch an array of thrusters and move it, then get the thrusters back.
And now, if Starship flies, and its re-usability works, kind of validates that earlier. Sure, you still couldn't move the ISS with it, because the whole thing would probably break apart. Or if there's a way to not break it apart, the logistics are still way too damn hard. Yet, just on the delta-V budget side, there's progress.
I should say was, as SpaceX are putting together advancements in all fields of technologies since the moon landings to do that. Being able to simulate the whole thing on a desktop computer first, then 3D print part of the engines simply wasn't possible in the 60s, and let's not forget material science.
