This is pseudo-philosophical nonsense. The only thing that steps out at me from this article is that we could avoid a lot of mourning if NASA took January off.
The problem with having a "space program", just like any other endeavor, requires an assessment of its value, both long-term and short-term. If these assessments of value indicate worth, we will continue to do it. If they do not, they will be shelved until we can find some previously hidden value.
Rocketeer, schmocketeer. We'd do ourselves well to put that "go where no one's gone before" mentality behind us with its promise of larger-than-life frontier exploration. The only reason an American footprint exists on the moon was because we didn't want our Cold War rivals to leave us behind in technology which might be needed in military applications against them. I love how that's been romanticized into some kind of philosophical manifest destiny.
Only when we stop looking at space travel as something heroic we do once in a while with the pomp and circumstance accorded to the victors in fierce battle will we actually find the reasons for continuing in this endeavor.
The future value of space exploration will come only from a statement of permanence and an eye toward practical concerns.
Space travel must produce scientific and engineering knowledge which increases its own capability, repetition, and safety such that space flight IS something we do every day, and not just every once in a while. Moreover, it comes from having a "next step" always on the must do list, which means that just circling the Earth, something we've known how to do for the entirety of the space program, must soon give way to actual destinations. Permanence. Furthermore, both with science/engineering benefit and possible commercial concerns (profit!), space travel must find a way to pay for itself without relying completely upon a tithe from governments. It will probably ALWAYS need to be funded by governments, big science always does, but it needs to find a way to chip in.
The big gestures like going to the moon help in the marketing of space travel and NASA as a whole, but ultimately there has to be some foundational principle of pragmatism, even in the face of the utopianism of pure science, which ironically allows the utopia its existence. It would be a shame to lose what is a necessary part of our future as a species to a set of well-meaning, yet hopelessly impractical, purist ideals.
