If you guys watched the video the Russians and pretty much every state that can send people into space see Helium 3 mining on the Moon to be cost effective, even with today's technology

There is more titanium OR aluminum in the top several meters of depth of an average square kilometer of the Moon's surface than is mined on the entire Earth each year currently. Also of course iron.
Even if there is a lot of Titanium and Aluminium out there, how will you transport all this back to earth? Do you know the cost of a lunar mission? It runs in to tens of millions of USD.
At the present. The initial step is always the most expensive one. Once a space elevator (or space bolas) is in place, the cost will be minimal.

Mining Helium-3 On the Moon

Why we need Helium-3, when we have millions of tons of Uranium available on the earth? Considering the difficulty in storing Helium, and the cost of conducting lunar missions, I can't understand the logic.
Helium 3 is now used as a cyro refrigerant, and has a value way way WAY higher than say gold. It could now be mined on the moon and shot back to Earth and be profitable. It's future value is in fuel for fusion reactors. This mining process would have to be automated and robotic to be practical.

These surface metals are relatively easy to purify, although the process is very different than what is used on Earth. They are in oxide form typically. Many other useful elements and materials. However the Moon is very poor in C, N, and "volatiles". As an example, it would be difficult to make plastics on the Moon.
Really the best way to think of the Moon is as one gigantic materials mine....also as a place where operations that have to be done in vacuum, would be extremely easy. examples, vapor deposition or ion sputtering.

So how of that stuff can we extract before the lunar to Earth weight ratio makes the Moon spin out into space?
What is there in the moon to extract? Any mining in the moon will be a million times more expensive than doing the same on earth. And none of the major metals are going to run out any time soon.

I remember some SciFi author had a story, where the Lunar colony declares independence and decides to leave Earth orbit (was it Clarke).
To make transport of minerals from the Moon cost-efficient, the system must be balanced - rockets won't do, space lift will. And as they say, what goes down, must come up (or do they). There is always something Earth needs to dump somewhere...

If half of the military defense spending is use in space program there will be human settlements in mars right now and we already mining asteroids.

I would rather chose to go to the Mars then Moon. I know the view from Moon is better but Mars is a better choice.
That will not happen in the near future. Even the most efficient rocket takes 1.5 years to reach Mars. And every trip costs around $100 billion. No country is having that much money right now.

The reason that it seems like the US has abandoned its space program is not because they actually abandoned it. It's because they now have something better that they want to keep secret.

Sorry people!
Nothing can touch this true classic Moon movie...

Ah, the memories. But you need to watch it in HD

Nice. Now we need to go beyond the Moon... Russian style

Apollo 18 is a pretty good movie.
Moon, about the guy that gets replaced every three years, not so good.

Hmm.... I used to like the horror movies in the past. But now I have lost my taste for them. Don't know.... if I feel like I want to watch, then I'll buy either the DVD or the Blu-Ray.

But hey, don't forget the classics - Destination Moon rocks, and it's on youtube.

Well, those "buckets on wheels" are still serving humanity. Scientists managed to locate them and use their reflectors to triangulate and measure precise distance shifts between Moon and Earth.
I have nothing against good Vodka, especially chilled down to -233 Celsius while looking up at the blue planet, laying down on my lunar sofa...
