Welcome to this 2 hour 2 minute Open Lines discussion.  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 www.parabolicarc.com/2013/11/12/50647 and www.newspacejournal.com/2013/11/12/bigelow-report-calls-for-use-of-cots-model-for-cislunar-transportation.  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.

Please post your comments/questions on The Space Show blog above.  If you want to email any of the participants, you can do so through me at drspace@thespaceshow.com.

During our 11 minute plus discussion, John, Bill, and I talked about Comet ISON which is now visible in the sky near Mars. We talked about its Thanksgiving close pass to the sun, its survival probabilities, and why this may be the comet of the century.  We also talked about a new report indicating small asteroids such as the one that came in over Chelyabinsk, Russia earlier this year may be more common than thought and may put us at more danger than previously thought.  Finally, we talked about the Olympic torch going to the ISS on a Soyuz last night, its upcoming photo op on a space walk and its return to Earth.

During our 11 minute plus discussion, John, Dr. Alan Hale, and I talked about the approaching comet ISON.  We talked about the brightness theories representing everything to that of as bright as a full moon to it fizzling out and not being very bright. We talked about the theory on this proposed by Dr. Ferrin, but Alan believed it was still way too early to make accurate predictions about this first time comet from the Ort Cloud.  Alan described the sublimation process, its path and flyby near Mars on or about August 20, then on to pass by Mercury and as a sungrazing comet,  finally be visible on Earth in late November 2013.  Dr. Hale was also asked to describe the tails of a comet, the dust tail and the ion tail.
