First let me say that the basic idea brought up by < REM @ MIT-MC > is valid in that a mass accelerator based on the moon would be worthwhile for industrial purposes. For the simple fact that the moon in comparision to an asteroid is a limitless supply of materials. And the mass driver does overcome the problems of the gravity well. The only problems that could be brought up would deal with the cost of establishing the mass driver, and the technology to create and maintain the mass driver both on the sending and on the recieving ends. But this role would be in a support role for near-earth bases, for the asteroid belt (which is the logical place to go) would be a little too far. I think that there is the minerals available in the asteroid belt without the necessary cost of importing them. I would also like to bring up the additional question to those in net.astro(.expert) as to what the actual compositions of asteroids are. The question could also include the theories as to whether the asteroid belt was once a planet, or is natural. Is there a source that I can refer to on what the various types of asteroids there are, and the mineral contents of the various forms of asteroids. One thing that I have thought of is that if the asteroid belt is a broken-up planet, then perhaps not only would the inner parts of an actual planet be available for study, but also the deep minerals would be available for easy strip mining. Therefor increasing the value of these colonies, and also we can see a worthwhile increase in the economic worth of asteroid mining colonies.
