Guest: Michael Heartsong. Topics: Mining asteroids for commercial purposes. Michael Heartsong of Promethean Enterprises, Inc. was our guest to talk about the Promethean Project, "Mining The Sky." Promethean has an extensive White Paper on this subject which you can download at http://www.miningthesky.com/brochure.html. In our first segment, Mr. Heartsong outlined their mining concept to address both NEO's as well as comets. You will want to pay careful attention to his plan and how "targets of opportunity" will be selected.
