Welcome to this 2 hour 11 minute wide ranging discussion with a surprising debate between two callers in the latter part of the second half of the show. During the first segment, we started out with a call from Paul to talk about his AIAA Spaceflight Challenge Program for inspiring students. The purpose of this program is to inspire students to be involved in space development and exploration. Paul will keep us posted on the project as it develops over the coming months. Charles Pooley called in next to tell us that his Microlaunchers book was out and that he and his co-author would be on The Space Show to discuss it in detail Monday, Jan. 13, 2014. The book, "Microlaunchers: Technology for a New Space Age," is available through Amazon. If you buy it and I suggest you do, use the OGLF Amazon portal so Amazon will make a contribution to The Space Show. Directions for doing this are on each blog archive, website archive, TSS website home page and on www.onegiantleapfoundation.org. Let me know if you have any questions. I believe you will be impressed with his long awaited book and hats off to Charles for finally getting it done and for doing a terrific job with it. In our second segment, we took a call from an upstate NY college student inquiring about the returning to the Moon, lunar commerce and such. Following Eric's call, Marshall called in from Texas to talk about how inspiring TSS has been for him. We also talking space mining issues with him, the use of robots and more. Our next caller was SLS John. John is a strong advocate for SLS and he again articulated the case for the completion of SLS. I challenged him again with the usual arguments against SLS which did not phase him. Dr. Jurist wanted to comment on what SLS John was saying so using another phone line, Dr. Jurist (Montana John) and SLS John had a lengthy and detailed exchange, both supporting heavy lift and SLS , although with reservations, especially from Montana John as you will hear in their discussion. Its an interesting discussion but I doubt it will change the minds of listeners regardless of how they see and think about SLS. That said, I strongly suggest you listen to their entire discussion many key points were addressed by both callers. As the show was ending, I went over some of the key upcoming guests scheduled for The Space Show. Please post your comments/questions on TSS blog above.
