Guest: Dr. Neville Marzwell. Topics: Space Solar Power, power beaming, leadership, public & private sector risk buy down, Elon Musk, electric cars. Dr. Neville Marzwell was the guest for this Space Show program to discuss his Space Solar Power (SSP) presentation from the December 2008 ATWG Conference. Dr. Marzwell's power point presentation, "The Technical Challenges for Space Solar Power" can be sent to you upon receiving your request. It’s 20 MB so to send it, I will need to use a large file transfer service, so let me know if you would like a copy of this PowerPoint.

Guest: Brian Weeden. Topics: Iridium 33 & Cosmos 2251 collision, space situational awareness, satellite location, orbital debris, United Nations. Brian Weeden was the guest for this special Space Show program which focused on the recent collision of the Iridium 33 and Cosmos 2251 satellite. Brian went into some detail during this discussion to let us know how satellites are tracked, the catalogs kept by the Air Force, commercial operators, independent companies, and foreign nations. We talked about liability, tractable debris, and all of orbital debris.

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.

Guests: Dr. Tom Jones, Dr. Charles Oman, Ron Small. Topics: Spatial disorientation, space motion sickness, vertigo, solutions. Our guests today, Dr. Jones, Dr. Oman, and Ron Small, are involved in a research project with the National Space Biomedical Research Institute (NSBRI) to assist pilots in real-time to overcome spatial disorientation for aviation and space. We also talked about motion sickness, particularly space motion sickness, and ways to combat it. Physiology plays a big part in both disorientation and motion sickness, so you will want to hear what our guests had to say.

Guest: Dr. Jordin Kare. Topics: Laser launch, power beaming, space elevator, laser weapons, Mockingbird. Dr. Kare returned to The Space Show for updates with laser launch systems and more. We learned about the beam module approach and his work to win the NASA Climber Challenge through his company LaserMotive (www.lasermotive.com). We also discussed heat exchanger propulsion and the use of different materials for the exchanger such as Silicon Carbide. As a result of listener questions, we discussed the laser for use with the space elevator and Dr.

Guest: Henry Vanderbilt followed by Open Lines. Topics: Space Access Society Conference, low cost space access, SUSTAIN, suborbital and orbital space transportation. Henry Vanderbilt, founder of The Space Access Conference, was the guest for the first ninety minutes of today's program followed by Open Lines for the last half hour. Henry discussed the origins of The Space Access Conference up to its current status. He told us who the speakers were to-date for this year's conference and said there was still time to contact him to be a presenter at the conference.

Guest: Rosanna Sattler, Atty. Topics: spaceflight participants, informed consent, liability issues, assumption of risk. Rosanna Sattler returned for this Space Show program to discuss spaceflight liability for companies and spaceflight participants. Our discussion started out with an understanding of the various terrestrial liability, tort, and other laws in place that will likely apply to commercial spaceflight.

Guest: Dr. Henry Hertzfeld. Topics: economics for the nation, NASA, and space, investment, launch rates, government spending for space and R&D. Dr. Henry Hertzfeld returned to The Space Show to discuss the current state of our national and global economy and its probable impact on space development and programs. We examined the economic impact on companies that need to raise money, those which do not have clearly defined markets, and on those companies that are self-funded.

Guest: Stephen E. Doyle, Atty. Topics: Space law, space property rights, space traffic management, liability, space debris, space tourism, and much more. Stephen Doyle was our guest for today's Space Show program to discuss various aspects of space law. As it turned out, this was a very comprehensive discussion on a variety of space law issues including space traffic management, space tourism, liability issues, space property rights, the Outer Space Treaty, international contributors to space law, and so very much more. I recommend this as a must hear program.

Guest: Alfred Zaehringer. Topics: rocket science, rocket equation, Mars, chemical rockets, space tourism, low cost space access. Al Zaehringer returned to The Space Show to discuss his two books. Al was the editor of "Rocketscience: The Journal of the Detroit Rocket Society, Inc. 1947-1952," which is available from http://www.apogeebooks.com. This is a must have reference book, one of the very best of its kind.
