Guest: Dr. Robert Zubrin. Topics: Goals and vision for space program, Augustine Commission. Dr. Robert Zubrin returned for this Space Show program to provide us with his assessment of the Augustine Commission's report and to put in context his goals and vision for our space program.

Dr. Pete Worden, Center Director for the NASA Ames Research Center, was the guest for the first hour of the show.

Dr. Robert Hoyt was the guest for this Space Show program. We began the interview with Dr. Hoyt telling us the basics about tethers. Tethers are either momentum exchange tethers or electrodynamics propulsion tethers working with Lorentz force interactions and the Earth's magnetic field. Dr. Hoyt then described these types of tethers in greater detail and the type of applications for each tether. In response to a listener question, he talked about being able to use tethers to move the ISS to another orbit though it would take about 18-24 months.
