Even as the moon landing was approaching futurists were looking to what should follow. They were looking at manned multi year missions based on the technology they had, reuse and incremental development of Apollo – Saturn technology. Just reading this article sent me of into a dream of what could have been. Just thinking about it made me sad, mad, glad: sad for what might have been, mad at those who sidelined the dream because of shortsightedness, glad that at least some had the sense to think-dream based on common sense.
Today Elon Musk and a few others are dreaming similar dreams maybe having read a few of the NASA documents though the basics are so common sense they do not have to have.
