Moon Mining Gets a Closer Look 485
happylucky writes "There are many obstacles to creating a space colony on the moon, primarily food, water, and oxygen. Since it is so expensive to bring supplies from the earth, some scientists have suggested that we mine the moon. In an article in the Toronto Star, Dale Boucher suggests the best way to do this would be to develop a mining colony. To that end, the Sudbury-based Northern Center for Advanced Technology has linked Canada's mining industry with some of the top minds on space.Mining the moon was considered earlier this month at the Planetary and Terrestrial Mining Sciences Symposium which attracted some 100 delegates, including experts from the Canadian Space Agency, NASA and the European Space Agency. There are other hurdles of course that need to be figured out. The moon's gravity is one sixth that on Earth. New research, however, may lead to a solution to this problem as well. It may be possible to develop a sticky compound that can be adjusted by UV light to help adhere boots and objects to the floor."

Anyone been watching the news recently? Congress is
on the verge of outlawing mining just to avoid the
bad press when a few minors endure the result of bad

The solution? Put the bosses in the mines.

And then there are all the reasons NOT to go. There isn't enough gravity; humans may be harmed by prolonged living in 1/6 g. The lunar dust is as dangerous as the worst lung hazardous mining dust on Earth, and apparently it gets everywhere. There will never be an atmosphere to shield from cosmic rays. The moon is sterile (except for our junk up there) so there's not much exo-biology interest.
Oh wait, now I know why: it's a great opportunity for someone to spend billions of dollars on playing around with fun toys!

You miss the point. Anything which one can make a profit doing, will eventually be done without "us" (whoever that may be) needing to focus on it.
If it's not getting done without government funding, it probably can't be done at a profit (yet).
That's what governments are for; doing that which is worth the expense of doing, but does not directly yield a profit.

Worst case scenario is "it doesn't look the same". Thinking that changing the appearance of things is some kind of crime is just arrogance, though; well obscured and wrapped in feel-good holiness, but it just boils down to I don't want it to change, so it shouldn't change.

If all they're looking to do is increase traction, there are much saner ways than pouring glue on their boots, (which would also cost you extra effort with every footstep.) Non-skid surfaces, for a start. I suppose they could bring a pot of glue with them and spread locally-mined crystalline silica if they wanted to save ferrying a pound or two of sand from earth.
What would be better is to find ways to use the advantage of the reduced gravity without worrying about the traction. Depending on the problem, solutions like "cable cars" or "conveyor belts" don't have to rely on motor-to-ground friction at all.
Finally, look back to the U.S. moon landings in the 1970s. Dust got everywhere. It was a huge problem. Do you honestly think "sticky" surfaces would last more than an hour before being rendered useless by the layer of dust?
Sticky is a non-starter.

Conservation is not a virtue for conservation's sake. It's a virtue when you are *saving something*. I don't put much of a value on rock. Frankly I think we can put the materials in asteroids and the moon to better use than they do currently.
And actually, animals do ravage their own ecosystems regularly.. they don't understand convservation or carrying capacities any better than we do. The deer populations up here in maine breed themselves into starvation on a regular basis, even in massively undeveloped woodlands. It takes a growth in predator populations to take them back down, or simple overpopulation.
We have lessons to learn. Doesn't mean we should just sit around either. Obviously you agree, sitting there on your mass fabricated computer filled with toxic substances, using your fossil fuel power and buying at least a few products that support the rape of our planet. So how about dropping the high horse routine?
I suggest looking into practical sustainability instead of radical ideology.

Problem solving is really just a question of setting priorities.

Then another dozen and then some more. Has it ever occurred to you that space exploration and the required technological/economical/political progress might be a big part of the solution to problems on our homeworld? If nothing else, colonizing space should give everyone a fresh perspective (figuratively) on Earth and its problems.

In case you hadn't noticed NASA's manned spaced program stopped being about space a long time ago. Whenever Congress debates NASA funding the #1 issue is what the impact will be on jobs in the districts and states of various politicians. When CRV and the return to the Moon ramp up the only priority for Congress is to insure all the current ISS and Shuttle jobs are preserved. The new NASA administrator would actually like a much cheaper, leaner and meaner manned space program than Shuttle and ISS. But if he cuts any of the pork Congress will slap him silly so he wont. Therefor return to the Moon will be staggeringly expensive, take forever, and fall way short of its goals just like 2 projects we know and love.

What is the point of having a permenant manned colony on the moon? We'll never terraform it. It will never be self-sufficient. The cost will never justify the science we could get out of it.
Seen the future have you? It's hard to say what would happen if Moon bases were built. I'm sure no one fore saw the "New World" becoming what it is today.
The lunar dust is as dangerous as the worst lung hazardous mining dust on Earth, and apparently it gets everywhere. There will never be an atmosphere to shield from cosmic rays.
Well due to the lack of oxygen, it's required that anyone who goes to the Moon wears a helmet. The same would go for the possible future miners. So dust inhalation is not really a concern. And their are materials that can help shield against cosmic rays. Building the base under the surface would probably help too.

We need to look at this stuff rationally to arrive at a solution to a practical problem. Condemning us all to death because we have not yet reached enlightenment, especially when you yourself are seduced by the things society offers you when you KNOW the price it extolls, is a bit elitist, rude, hypocritical, short sighted and boorish, frankly. And not particularly helpful either.
I stuggle with this every day myself. But the technology and methods we use today are the only tools we have to take it to the next level, and that includes our cognititive and social developement. You're in a hurry.. that's great, push, that's necessary.. but you might want to consider your methods, cause these aren't particular effective. A reasoned response might hold some more weight than rambling about bunny rabbits and claiming we all deserve to die.
Just a thought.. probably sounds worse than I intend it. Hopefully you don't take it that way.

Your weight on the moon is approximately 1/6th of your weight on earth.
So a 200 lb man weighs roughly 33 lbs on the moon.
So while it may seem necessary to use a sticky material to adhere one's boots
to the floor -- its probably easier to carry 1000 lbs (Earthweight) of weights
which would add an additional 166 lbs of Moonweight, making a 200lb earth person
weigh 200 lbs on the moon.
The sticky stuff isn't requred. Just some evenly distributed body weights would
do the trick. Although... no defense contractor gets rich with the simple
solution.

Balderdash. The Romans thought the purpose of government was to bring glory to the people. The medieval christians thought the purpose of government was to spread the gospel. The chineese thought the purpose of government was to maintain the celestial order.
Our own founding fathers may have had their own ideas about what they were forming our government for, but today that same structure is seen both as a way to make a profit, a way to protect unintelligent things, an avenue for power, and a thing to be avoided -- depending on who you talk to.
The purpose of a government is to do whatever those that give the government power want it to do. Anything more is just philisophical "should"-ing, and should always be dismissed until the points so made are affirmitvely proven.
