Forgive me if this has been discussed. I have recently heard of our nation's interest in harvesting Helium 3 from the moon in order to fuel our television sets.
Could mining on the moon (digging out about a quarter mile of regolith) affect its orbit, the Earth's tides, or anything else we may need more than, oh, say -- American Idol?
Intelligent and/or sarcastic responses only, please. :wink:
