This is pretty interesting, I'd so love to be involved in that.

Do you think realistically they will be close within the next decade, and how far do you think we will go in the next century?

I mean, how on earth can you mine and collect these materials in negligible gravity?

In the next century it will probably be an entire relevant business.

I would assume they mine with shaped explosives; collecting them seems like not too much of an issue as long as you've got a steady supply of rovers or whatever you would call the type of vehicle that does these things.
