Back to the Moon 312
starexplorer2001 writes "Space.com is reporting that NASA's planned trip back to the Moon isn't without a significant amount of science and technological innovation. Simply 'sponging off Apollo' won't do it. Among the issues: safer human spaceflight, lunar ice, sustainability, robotic scouting missions and more. This won't be easy."

Your short-sightedness is amazing here. "There's nothing more to learn on the Moon"? Where do you get that from? We've sent precisely six manned missions to the moon in all of human history. Only twelve humans have actually walked on it. Almost none of them had a strong scientific background (although many learned it in order to be more effective). Yet we know everything there is to know about the moon according to you. Your hubris is absolutely mind-boggling.
Experts have long admitted that launching a mission to Mars from the Moon is far more difficult than doing it from here.
Umm...exactly who is proposing we launch a Mars mission from the Moon? Bush sure isn't, and neither is any other sane person. To build up a launch infrastructure on the Moon would be a multi-decade endeavor and would likely eclipse a Mars mission for sheer complexity and cost.
No, the Moon is a beta test site, if you will. No human has left low Earth orbit for almost four decades! All the engineers who made Apollo work are either dead or retired. Our heavy lift capacity is completely moribund. With but few exceptions, we're going to have to learn a bunch of things all over again. Which is a better place to learn these things, a spot that's only a couple of days away from the Earth via free-return trajectory, or a spot that's months away with no such option? It doesn't take much more intelligence than a turnip to understand the former is far more advantageous than the latter. It's safer, it'll cost less, and we'll get quicker "knowledge returns".
Once we rediscover how to get to the Moon, setting up a moonbase will essentially be a "dry run" for setting up a Mars habitat. True, the lunar surface and Martian surface don't have a lot in common, but they're both immensely rugged and challenging environments to construct even a sand castle. Learning how to build a moonbase will teach us in no small part how to build a Mars base. Or would you rather we get to Mars first then try to figure all this out then, when astronauts are beyond any easy help from Earth?
NASA has become the "Santa Claus" of the U.S. Government. Keep the children excited and maybe they'll think there really is a future, after all.
While I'll freely admit NASA is merely a vast sinkhole for funds and functioning solely as a reason to have a space station right now, the return to the Moon does not fit that category. There is a future if ostriches like yourself would only see it. Instead, your cynicism and politcal bias appears to be clouding what might otherwise be a capability for sound judgement on your part.

So, if the $0.10 that actually went to useful R&D resulted in $9 in economic growth... then if the whole $1 that went to NASA had been retained by the economy (it was taxes, remember) then $90 in economic growth would have resulted. (As the value not destroyed by NASA on a project with no positive economic impact, would have circled the economy at least ten times before going somewhere that was a dead end, so each $1 retained would have resulted in at least $1 in R&D even if the initial dollar was spent on floor wax.)
Socialists (eg: anyone who supports government development of anything) always point to the benefits, but never pay attention to the costs. And the costs are always much higher than the benefits.
If they' just shut down NASA a private space program would get to the moon again faster than NASA could. NASA is interfering with private efforts
And this is just the economic argument. It doesn't even address the massive number of truely talented people who could have prusued access to space in an economically viable way, who were instead wasted working for NASA for 20-30 years. NASA's brain drain probably exceeds its budget impact by an order of magnitude. Imagine what kind of a space industry we'd have if venture capitalists could have underwritten access to space back when the technology was just viable and everyone wanted it? (Unlike now when 40 years of NASA incompetance have caused people to give up on the possibility.)
Fortunately, private entities are working on it. But they have to fight NASA every step of the way.

Presumably, there turned out to be great numbers of unexpected problems, each of which required new equipment to be added. More equipment meant more weight which meant bigger rockets which add new layers of technological problems to handle, which means more manpower and time and therefore more money.
I like to think that we could do it cheaper today, what with readily-available computers both on board and in design, and 40 years advances in metallurgy and engineering technique. Assuming we wanted to do the same thing we did before, that is: put two guys on the moon and bring 'em right back.

I like the bounty system. You have multiple competitors for the goal, and the first wins. Increase the reward each year until somebody gets it.

Private interests were able to fund and develop cars, electrical power, and telecommunications because the advances there had immediate and obvious commercial benefits. People were all too happy to buy Model Ts and stop riding horses, and they were happy to have electric lights. Telecom's a little different: a lot of the development of infrastructure for telecoms has been government subsidized because of the enormous capital expense.
Where's the commercial benefit to space exploration? Especially in the 1950s-1970s when it was at its peak? If you really think private interests could have had a man on the moon in 1969 you're a complete fool. Even today, private interests (which are only funded by 1) wealthy individuals like John Carmack, and 2) the incentive of big prizes from government money) haven't managed to get a man out of the atmosphere.
In today's economic environment, if there's no profit to be gained by something within 5 years, it's simply not going to be done.

Why was it possible to go to the moon in '69 but not possible now even using the same old technology? Has the moon/earth/atmostphere/space changed?
A little thing called "lost technologies". It is entirely possible to forget how to do things.
A goodly portion of the knowledge encapsulated in any serious technological endeavour cannot be captured in blueprints and technical documents. It exists in the heads of the engineers, scientists, and astronauts who actually do the stuff. Going back to the original documents will give us a head start in re-learning how to do it, but not much more than that. If you don't have a teacher that actually knows how to do it, you are in the same position as someone learning how to speak Ancient Egyptian, given nothing but walls of hieroglyphics. It is possible to deduce some semblance of meaning, but it's frightfully hard to actually learn how to do it.
The primary problem is that the senior NASA engineers in 1969 are mostly dead now. They did not have any apprentices whom they could mentor in the arcane business of placing men on celestial bodies, and no young masters in that art grew up in their footsteps applying their own clever insights to refine the art further. The entire business was pretty much forgotten, and now we are back where we started, albeit with some hieroglyphics that we could spend some time trying to decode if we had to.
At Cape Canaveral, there is a complete Saturn V launcher on display at the Visitor's Centre. This is like the Great Pyramid of space missions -- a complete, working example of a device to put men on the moon. Unfortunately, they chose to lay the rocket on its side, which it was never designed to do. So structurally, the device was completely destroyed and is now useless, having even lost much of its value as an engineering archive.
So in many respects, we simply have to start over, and re-learn what we already knew.

I get your point, but I don't think the situation is as dire as you present.
We will have to redesign the systems. Newer composites and materials that are lighter, more resiliant and possibly, thought not probably, less expensive. But in any case, much different. Faster computers, better robotics, more intelligent software... the possibilities astound me.
I really don't think that circa 1969 expertise, even having been maintained these several decades, would be all that relevent today. I see it as a positive thing actually since we're now forced into a redesign that, had those entrenched interests persisted, we might not.
