In my Class on Controversies in Science at OLLI-UTEP the other day, Mr. Kappus, Instructor, mentioned that on one asteroid water--the H2O variety--has already been posited as present.
That got me and the Instructor to enter into a fantasy discussion that may very well turn out to be true: There might be some asteroids, meteors, or just rocks flung out into space floating around the sun that contain all manner of minerals.
He voiced the opinion that there would have to be two spacecrafts--one positioned near a space object and the other at some distance above it, both working in consort to locate potential mineral finds and dig or blast them out from their rock beds.
If its natural to assume that the earth isn't the only planetary object containing minerals such as gold, it seems sensible to populate the entire solar system with mineral probing spacecrafts (unmanned) to explore for them.
Indeed, I think Mr. Kappus with his space-probing vision has chosen wisely the field of geology for a career, since it is that scientific field which is devoted to ascertaining mineral presence in any rock formation on whatever space object!
