Jeff was our first caller regarding propulsion, SLS, Orion, SRBs, ATK, advanced technology as compared to existing or old technology, composite materials, and much more. I also asked him about sequestration in the defense side of space. Todd sent an email to Jeff to inquire what he thought about the possibility of an SLS cancelation. We talked about the possibility of canceling the SLS project due to economic issues with the government. Jeff also spoke about XCOR, ULA, Rocketdyne, pumps, and lower cost options with NewSpace companies. Charles Pooley called in to talk about the Indian Mars mission, the 4 stage PSLV rocket, and his forthcoming book due out before the end of the year. Tim sent in a STEM article & he called so we talked about the article but both of us did not think much of the author's comments on the subject. Next up was Doug from Southern California regarding articles about Bigelow and Lunar Cots. The use of SLS was discussed for commercial missions or public/private partnerships and I parted company from his analysis and conclusions. The articles suggested by Doug included and As frequent listeners know, Doug is a strong advocate of lunar cots. I also asked him what the profitable commercial mission would for lunar cots. Mostly Doug talked about selling rides to NASA except with the SLS, they would be using a gov. vehicle. It’s an interesting discussion. What do you think about the ideas we talked about? Andrew from Tucson was our last caller and we learned he has been busy with precision tool and engineering for rocket parts. We also talked about the need for cultural changes in the country and he talked specifics in this area, not with generalizations. We also talked about astronomy, career paths, and telescopes.
