I’m curious just how much do you think it would cost per pound (using pound as a measure of mass which really isn’t correct) to bring back a thousand pounds or so of material from the asteroid belt? And how did you arrive at your figure? Hint you could use the Apollo program as an example
What if you could send a swarm of small "thruster bots" out to attach to an asteroid and push it into an Earth/Moon L point for harvesting and that you could do this for just a few million dollars? At a return of investment 1:1000.
