Guest: Open Lines with Dr. David Livingston. Topics: nuclear rocket propulsion, VASIMR, space policy, ISS, Constellation, Ares 1. This Open Lines program was a two hour discussion with many listener phone calls and email/chat questions. As with all open lines shows, they have a mind of their own and go off in a direction that you the listeners want. An Open Lines program is a listener driven content oriented program so here is what we talked about this time. During the first segment, I led with a discussion of the copyright issues for The Space Show.

Guests: Gary Moir and Don Harvey. Topics: Apollo 13, Lunar Module Descent Engine (LMDE), Apollo history. As this week celebrates the 40th anniversary of Apollo 13, our guests Gary Moir and Don Harvey talked about their Apollo and Apollo 13 experiences, the Apollo space program, and space policy and programs today. In our first segment, Gary started the discussion with a look back on the Apollo program and Apollo13. He talked about what it was like being called out of a USC class and flown to Houston to work the Apollo 13 propulsion problem.

Guests: Classroom guest panelist Paul Breed with co-hosts Dr. Livingston, Dr. John Jurist, Dr. Jim Logan. Topics: The Rocket Equation and why it matters. Welcome to Lesson 2 The Rocket Equation in our Space Show Classroom series. This nearly two hour program focused on The Rocket Equation, how to understand it, use it, and why we build and launch rockets the way we do.

Guest: Dr. James Dewar. Topic: nuclear rocket, breaking the taboo, private space development and industrialization. Dr. James Dewar was our guest to discuss his new Apogee published book, "The Nuclear Rocket: Making Our Plane Green, Peaceful and Prosperous." This book and his earlier book, "To The End Of The Solar System: The Story of the Nuclear Rocket," will soon be on the One Giant Leap Foundation book page as an Amazon partner. Buying these books from the One Giant Leap Amazon link allows Amazon to financially support The Space Show.

Guest: Dave Ketchledge. Topics: "Rocket Science," nuclear power, space policy, space education. Dave Ketchledge was our guest to discuss his new book on CD, "Rocket Science." You can order this book and find out more about it by visiting his website, www.rocketengineer.bravehost.com/. During Segment 1, Dave talked about the need for space engineering and rocket education, how his book fills this need, and what it means for future engineers in all disciplines, not just those related to space.

Guest: Ross Tierney was the guest for this in-person taped interview conducted here in Cocoa Beach on Thursday, Nov. 13, 2008. This was a very hard-hitting interview with Ross about Direct 2, its technology, its likelihood of being adopted by NASA as an alternative to Ares 1, and more. I asked Ross why we should have confidence in Direct 2 when it was basically a PowerPoint presentation given that it has not yet undergone any metal bending, any development or testing. I asked why there would not be design problems with it as there are with Ares and the NASA selected hardware.

Guest : John Powell was with us for this Space Show program to discuss his new book published by Apogee, "Floating To Space: The Airship To Orbit Program." John discussed airships to space, from the basic airships to the more advanced airships that he is planning on building in the future. We discussed altitude, density, shockwaves, and much more. John also spent considerable time on the economics of this potential spaceflight system, so make sure you hear this part of the program. He talked about upcoming launches and more PongSat opportunities.
