Broadcast 1357 (Special Edition)

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.

Broadcast 1214 (Special Edition)

Guest: Dr. Leik Myrabo. Topics: Lightcraft, Beamed Energy Power, low cost space access. Dr. Leik Myrabo returned to The Space Show for this program to discuss beamed energy propulsion (BEP) as well as his new book recently published by Apogee, "Lightcraft Flight Handbook LTI-20." This book is available at http://www.amazon.com/dp/1926592034?tag=onegialeafou-20 . The book is co-authored by Dr. John Lewis.

Broadcast 1114 (Special Edition)

Guest: Dr. James Woodward. Topic: Mach/Woodward Effect, revolutionary propulsion, gravitation, inertia, electrostriction, specific impulse, interstellar space travel, wormholes. Dr. James Woodward returned to The Space Show for updates on his work with the Mach Effect, also referred to as the Woodward Effect. The first part of the discussion served as primer to the work of Ernst Mach, what the Mach effect is, and how it’s plausible that it could someday lead to interstellar space travel.

Broadcast 895 (Special Edition)

Guest: Dr. James A. Dewar. Dr. James Dewar returned to The Space Show to explain and discuss nuclear rockets and what they would mean for space and economic development were they to be used to obtain low cost space access. Dr. Dewar began our discussion with a good explanation of how a nuclear rocket engine works and the advantages such an engine provides in terms of specific impulse. An engine with a higher specific impulse means a significantly larger payload can be brought to space faster than if the engine had a lower specific impulse.
