Argument: Returning to the Moon would be an unjust act of nostalgia
Buzz Aldrin said, on the 40th anniversary of the 1969 moon landing in July 2009, that a return mission to the Moon would be only a, "glorified rehash of what we did 40 years ago."
Robert Zubrin, president of the Mars Society: "NASA was not created to do nostalgia acts. It was created to storm heaven. For NASA to make as its central goal repeating technical accomplishments it did 50 years before is a complete abandonment of its purpose."
