Feedback: What did you think of this show?: 

Marshall Martin was the guest for this special Space Show program. Marshall is a faithful Space Show listener, an unaffiliated space advocate, and a listener that asks exceptionally good questions to a wide variety of Space Show guests. This interview started out by asking Marshall about his interest in space and how he comes up with so many unusually high quality questions for Space Show guests on a wide variety of topics. As you will hear when listening to the program, Marshall applies some engineering rules to his question process. Marshall was also questioned about his view regarding low cost space access and how it can be achieved. He also spoke about the space elevator and what he sees as potential barriers to creating the elevator. We talked about rockets and improving their performance and much more. With a listener question, the subject changed to SSP. Martial put forth a few scenarios where SSP could transform energy use and thus nations right here on Earth. He talked about methods of doing SSP using petty much existing technology. We also talked about the status of beaming energy, using SSP in space as well as here on Earth and more. He talked about the shortage of funds to develop SSP, the R&D research funding habits of big oil and others, and the political process which today does not support SSP development and R&D. The environmental issues regarding energy usage and SSP were a focus of Marshall's comments. In reply to another listener question, Marshall identified a priority list of commercial projects that we should be doing in space. Since these projects were centered between Earth and the Moon, he was asked about deep space projects or even Mars or something taking place beyond the Moon. He suggested we needed to really learn the Earth-Moon space commerce projects and business really well before venturing further out to space. Marshall suggested something like a ten year learning curve would be reasonable. Another listener asked him for his thoughts on ITAR. Listen to what he has to say. You might be surprised at his comments and insights as to the ITAR issue. Toward the end of the program, Marshall was asked about dreaming and reality and to know where the dream stops and reality must take over. His response to this question was also very interesting. Marshall also made reference to his thinking that we should not have spent so much time in return to flight after the Challenger and Columbia accidents. He suggested a 6 month period might have been all that was necessary. He was taken to task on this by another listener, pointing out reasons other than just engineering as to why the return to flight periods were far longer than 6 months. You will want to hear Marshall's response regarding these listener comments. Marshall Martin is available to receive your comments and questions at
