I wish Ears would leave science to the professionals and stop interjecting his 99 IQ into the mix.
To minimize the risk, this asteroid they're talking about had better be smaller than the one that just struck Russia last month (that baby could've conceivably taken out a large city, had the parameters been a little different), in which case, a hundred million bucks seems excessive.
Better to leave it where it is, imo, and send a robotic probe to it, than bring it back here. Then, if it's found to have lots of platinum, gold, rubies, whatever, let the robots mine it in place and bring the good stuff back, while leaving the worthless stuff where it is.
Lets not also dismiss the problem of gravitation. It won’t happen fast, but parking a rock at a sufficient distance from the moon could cause enough wobble to disrupt tides, weather, aurorae, etc.
This is a harebrained scheme that could cause real world problems. We’d be better off parking it at a La Grange point and taking trips out to study it.
Nelson is an embarrassment.
