Released: 2 November 2015 Duration: 53 minutes, 33 seconds   Host Paul Carr interviews Dr. Martin Elvis of the Harvard Smithsonian Center for Astrophysics. Martin Elvis has a substantial background in high energy astronomy and astrophysics, studying quasars and other huge, highly energetic phenomena deep in the universe. He tells us why he has turned his attention to asteroid mining, and explains his model for determining how many asteroids we should be going after, and how we can find them. There is a case for much better surveillance of Near Earth Objects (NEOs) using space based infrared cameras. Today's sophisticated solid-state Gamma Ray and X-ray spectrometers can give us quick spectra that determine elemental composition. Also, the Earth often has temporary moons, but catching then in the act is tricky.   Links: Martin Elvis - How Many Ore Bearing Asteroids?
