Human spaceflight achieves its goals and appeals to the broadest number of people when it represents an expansion of human experience.Think Apollo astronauts walking on the moon - definitely a new realm of human experience. Science, economic development, technology spin-offs, and education are "secondary objectives" - potentially valuable but not necessarily worth the costs and risks of direct human involvement. I guess I agree with this, though I think it's somewhat short-sighted in terms of economic development and educational inspiration.
Apollo was very much about "primary objectives" (especially national pride and international leadership in the Cold War). But the "secondary objectives" paid off handsomely for the US in development of high tech industry and in the inspiration of baby boom kids like me who went on to become the engineers and scientists who drove the technological and economic development of the US in the 1970's and beyond. Could the US have achieved those results by directly investing in Earth-focused technology and education? Possibly, but it was really the fact that there were human astronauts that got me intensely interested in science and technology (after first wanting to be an astronaut).
In any case, they definitely see a continuing role for human spaceflight, but they suggest that we be more clear on why we're doing it. In practical terms, they recommend completing the ISS, retiring the shuttle on schedule, keeping the ISS operational as an international laboratory until 2020 (current plans end at 2016), and clarifying the moon/Mars strategy that was defined (rather vaguely on Mars) in the 2004 Vision for Space Exploration. They briefly mention expanded use of commercial space flight services and they also discuss ideas for increased international cooperation on space, including China and India. I think this report is a useful document for people interested in human spaceflight and the future of NASA, whether you're a space fanatic like me, or the president-elect of the United States.
