Welcome to our Open Lines show and my return to broadcasting given my post surgery recovery from my Oct. 1 spinal sugary. It was great to be back on the air. During the first segment of our two hour show, I updated everyone as to my post surgery recovery progress, I dedicated the show to the memory of our near friend Declan O’Donnell who passed away October 1 of this year, then I updated everyone on the progress being made on our new website development project and my ability to start fulfilling Indiegogo perk orders. As I stated, there have clearly been delays due to the first two weeks post surgery but we are getting back on track and I expect reasonable progress moving forward. As I explained I continue to have mobility limitations and sitting issues but things are improving all the time so I expect the delays will soon be a thing of the past. Several times during the program I mentioned booking future guests now that I am back on the air and suggested those of you that selected the co-host perk or the host your own show or be your own guest perk take advantage of the available dates for the balance of 2015 to bring your co-host guest to the program, or your host your own show to the schedule. Let me know and I will support you in invitations, etc. to get these programs booked with you even before the new website is launched. I also read an email from Matt from Switzerland who wanted to follow up from the earlier show with Ally regarding some sort of online virtual space advocacy training. If this interests you, post comments and your ideas on The Space Show blog. Matt will see them and maybe interested parties can get something going. Our first caller was Dr. Rowe who expressed misgivings about all the talk about being able to have humans walk on Mars by 2030. Dr. Row cited some of his well known and highly regarded medical research in support of his statements but as usual, committed space advocates challenged him. One was by text message to me which I did not read on air but was highly critical of Dr. Rowe wondering who he was and why in the world he would be talking about such things. Via a reply text I did tell this listener who Bill was and briefly listed his credentials for his research. I know his work is controversial and many listeners to this show do not support Bill’s conclusions but that does not invalidate his work. Doug asked Bill about running the numbers for what propellant it would take to spin up a craft with a tether long enough to get one gee but relatively low RPMs as the subject moved to needing to be in 1g and maybe even marginally less gravity would not work for humans. Lots of discussions followed about the gravity prescription issue, the need to know it for BLEO spaceflight, then Doug expressed his ideas of why it was not so important to know the gravity prescription at this time. Don’t miss Doug’s full comments on this subject and see if you agree with his perspective or not. Bill had some other medical issues to talk about, especially cardiology issues with Irwin and Armstrong. I have tremendous respect for Dr. Rowe’s work though I am not qualified to do any type of due diligence on it as I am not a medical doctor. Still, knowing it is controversial, especially with segments of The Space Show audience, I urge space cadets to be more open minded rather than married to agendas. In the end, Dr. Rowe’s work may prove more valuable and important than many think or would like to think. After a decent discussion with Dr. Rowe and listeners on related topics to Bill’s phone call, we started talking about the movie “The Martian.” This discussion took us through the rest of the show with breaks here and there for different or related topics. Everyone who called to talk about the movie like it and we did have some fun discussions about the movie and maybe some different scenarios.
In the second segment, John from Freemont, CA called to talk about the movie. he also talked about the gravity prescription and the plans by the SSI to do some sort of gravity prescription experiment. I talked about that as I have done shows on it and spoken to Gary Hudson about their efforts to fund this experiment,. He also mentioned the SpaceGAMBIT Organization which sounds very interesting. Check it out at www.spacegambit.org. June from Tucson emailed us wondering why there was criticism of the NASA Roadmap To Mars. I started answering her somewhat reluctantly but Doug called and I passed the response to Doug who handled the reply to June with a few side comments from me. In the process of talking about the roadmap, we talked about going to Phobos, cislunar development, SLS launches & much more. Doug then spoke about the movie which was the main reason for his call. During the conversation I incorrectly referenced a Dr. Lurio text to me over the weekend but fortunately Charles was listening to the show, sent me the correct text which I read on air. Charles then called the show and we had a good discussion about the movie, sci fi in general, and certain issues surrounding the movie. He also went into detail on the three items that made him see Hermes in the context of 2001. Advanced propulsion came up and several us wondered why nuclear propulsion was not a NASA solution to the rescue of the Martian. Here, we talked about the movie being about a NASA government program, not focusing on commercial or Newspace. Dr. Lurio offered a reason for this and I reminded listeners of this topic on the interview we did with Andy Weir several months ago. John Hunt called and we talked about audience and age differences with the movie. The last caller was Tim from Huntsville who saw it with friends, including non-space cadet friends. The non-space cadet friends liked the movie as much as the space oriented people liked it.
