The Future And You -- September 29, 2010

Les Johnson (NASA physicist and manager) and Dr. Gregory L. Matloff (professor of astronomy) are today's featured guests.

Topic: (Second of two parts.) Paradise Regained: the Regreening of Earth. Why the only way the ultimate goals of environmentalism can be achieved is if we stop using the earth as the source for our civilization's ever-growing need for resources, and instead tap into the much greater natural resources which surround the earth, in space.

Hosted by Stephen Euin Cobb, this is the September 29, 2010 episode of The Future And You. [Running time: 30 minutes] This was recorded in front of a live audience on July 10, 2010 at LibertyCon in Chattanooga.

Les Johnson is Deputy Manager for the Advanced Concepts Office at the NASA George C. Marshall Space Flight Center in Huntsville, Alabama. In his spare time he writes popular science books and articles. He was the technical consultant for the movie Lost in Space.

Dr. Gregory L. Matloff is assistant professor of physics at New York City College of Technology. He has consulted for the NASA Marshall Space Flight Center, is a Fellow of the British interplanetary Society, is a Hayden Associate at the American Museum of Natural History, and is a Corresponding Member of the International Academy of Astronautics. His pioneering research in solar-sail technology has been utilized by NASA in plans for extra-solar probes and in consideration of technologies to divert Earth-threatening asteroids. He has authored or co-authored more than 100 research papers and eight books, which have been cited about 400 times. One of his books, The Starflight Handbook (Wiley, 1989), was co-authored with MIT science-writer Dr. Eugene Mallove and helped establish interstellar-propulsion studies as a sub-division of applied physics.

In addition to being scientists, public speakers, and friends, Les and Greg have collaborated on a number of popular books. They joined forces with C Bangs for Living Off the Land in Space (2007), as well as for their latest book Paradise Regained: The Regreening of Earth (2009). With Giovanni Vulpetti they wrote Solar Sails: A Novel Approach to Interplanetary Travel (2008).
