We discussed many subjects including the Space Studies Institute (www.ssi.org), closed system environments for lunar and space settlements/habitats, asteroid deflection and planetary defense, to space investing with the entrepreneurial companies and other commercial space business ventures. Dr. Valentine spoke in some detail about planetary defense, the gravity tractor, and even the Planetary Defense Conference which will be held next year.
