Given that it's not a publicly traded company...	TheWraith	Apr 2012	#13
I find your publicly traded cynical synopsis to be ironic, but not stronly so.	xtraxritical	Apr 2012	#59
That's what I thought.	harmonicon	Apr 2012	#14
Helium 3 's potential economic value is as high as ~ $3 Billion a ton	Motown_Johnny	Apr 2012	#146
It would seem	quaker bill	Apr 2012	#3
Not at all. That grossly underestimates the sheer amount of resources present in asteroids.	TheWraith	Apr 2012	#12
To say nothing of the definition of "trace" in a twenty-gigaton object. (nt)	Posteritatis	Apr 2012	#16
Exactly. In this case, "trace" amounts of gold means ~10,000 tons.	TheWraith	Apr 2012	#23
Indeed. IIRC, there's actually some asteroids with quite a lot of precious metals in them.	backscatter712	Apr 2012	#82
Notes on platinum and iridium.	TheWraith	Apr 2012	#98
Just looking at iridium's properties.	backscatter712	Apr 2012	#131
This could be highly profitable. Energy is easy to come by in space.	Katashi_itto	Apr 2012	#5
I love that picture and agree with you about how important this first move is	lunatica	Apr 2012	#22
LaGrange point 5 Would become a jumping off point	Katashi_itto	Apr 2012	#27
For the darker side, watch Outland	BootinUp	Apr 2012	#50

Why thank you! :) Here is some real deep space footage too!	Katashi_itto	Apr 2012	#62
Oh man - isn't that the most beautiful?!	calimary	Apr 2012	#64
I'm also glad this first step is being taken.	kentauros	Apr 2012	#108
Really cool ideas! I am sure either one or a hybrid of energy process will end up being a solution	Katashi_itto	Apr 2012	#121
Thanks for the laughs!	kentauros	Apr 2012	#124
You can use the dust of the asteroid mass you don't mine as reaction mass as well.	AtheistCrusader	Apr 2012	#133
YES!	Crowman1979	Apr 2012	#6
Would be pretty cool if we found too many resources so that we wouldn't even	chrisa	Apr 2012	#19

Blow bubbles of the material and you don't need to soft land them..	Fumesucker	Apr 2012	#73
Now that could be a thought.	TheWraith	Apr 2012	#77
If the shell material is strong enough and the overall density low enough it could float in air..	Fumesucker	Apr 2012	#80
I'm thinking the material is more valuable up there.	sofa king	Apr 2012	#125

Mining Asteroids like like exploiting an earth-like planet???	Odin2005	Apr 2012	#47
cameron wants to get into the off-world mining bizness	solarman350	Apr 2012	#117
Or he acknowledges the fact that greed is what gets people to go to new places.	Katashi_itto	Apr 2012	#122
