Closer to Deducing the Origin of the Moon 265
eldavojohn writes "A giant explosion on the sun in January of 2005 allowed SMART-1 (a European spacecraft orbiting the moon) to detect what elements the moon is made up of based on the X-rays from the sun's explosion. This allows scientists to speculate on the moon's origins while seeing data from all over the moon as opposed to the core samples we have collected and returned in the past. From the article: 'Scientists responsible for the D-CIXS instrument on SMART-1 are also announcing that they have detected aluminium, magnesium and silicon. "We have good maps of iron across the lunar surface. Now we can look forward to making maps of the other elements." said SMART-1's Principal Investigator.'"

It is difficult to calculate because I couldnt find much info on sending stuff back from the moon, I am willing to bet it is quite a bit cheaper. But the infrastructure on the moon etc ruins any math. It would be break even for gold to be sent into space...and retrieving it would probably be long term profitable. (providing you can find enough gold)
Platinum is 1200 dollars per ounce making it much more possible, if sufficient quantities could be found.
The cargo ship would probably be reasonably priced...no equipment on board, doesnt need to be very fast, just a computer control system and the rockets etc necessary to bring it back in. Could be an interesting proposition.

Origin, or composition? (Score:1, Insightful)
Composition might do well to helping them deduce where the moon isn't from, but I can't really see it definatively stating the overall original of the satellite. Heck, even earth may have come as an offshoot of a larger object at some point in time.
Bah, and posting AC since I moderated in this topic already

I mean, nobody has seen the gold in Fort Knox in years, but it's been traded around left and right. Plenty of people are willing to pay for pieces of paper saying they own some gold - why not just prove it's there, stake a claim on it, and then sell it here on Earth?
We can have an entire imaginary Moon economy! Awesomeness++!

'Origins' aside, it's mining companies (and venture capitalists with an eye for off-world enterprises) that will be most interested in these findings, lending the idea that they are likely funding some of this research.
While this may sound absurd, it's perhaps worth asking: How much rock do you have to move off the Moon before the Earth starts seeing climatic changes as a result? Any one know of research into this area? Given the blatant denial certain first word countries have evidence in the face of an eroding Ozone layer, let's hope the moon isn't laden with valuable metals, ores and other resources..

I love gold people... at a fundamental level they don't realize that both paper and gold are completely useless unto themselves, and are only worth what people will pay for it. If you really worry about your well being in an apocalypse, buy canned food and ammmo, because that is all that will be worth anything.
