If the whole point of the endeavor is just another space race exercise to demonstrate American prowess like the we did in the 1960's-- perhaps that's a waste of effort? Do we really need that symbolic achievement at such an enormous cost? Not to mention the opportunity cost of having to drop more scientifically productive robotic missions?
The fact that the dithering idiocy of our current "administration" is even uttering anything about a moon mission sort of makes me think they see this as just a baloney "show-the-world" stunt.
What if, instead, there was a focus on true science, unmanned missions, and perhaps steps towards actual space applications: mining, asteroid protection, and staging for permanent space installations ?
