Space Show 2011 Fundraising Campaign

Annual Appeal, Nov. 21, 2011

Dear Space Show Listeners:

My best wishes to all of you for a great upcoming Holiday Season and New Years.  The Space Show and I personally wish you a terrific 2012 chocked full of health, happiness, economic prosperity, and a peaceful world.  I, like all of you, hope for a year of  significant and productive space development. The Space Show/OGLF is absolutely 100% committed to that long term outcome.

Permit me to take this opportunity to say thank you to all of you who have so generously supported The Space Show/One Giant Leap Foundation (OGLF) during this year and in past years. The Space Show relies entirely upon your support for its continued operation and programming. And we never ever take fees from guests to be on the program though many guests use The Space Show for the promotion of their fine books and exciting intellectual property.  To continue with free program access, archives, podcasts, webinars, The Classroom series, and programs for the coming year and beyond, along with the opportunity for many of you to continue promoting and discussing your own work, projects, and views, we need to be ever stronger in our financial foundation for 2012 and the future.

This year is quickly coming to a close, and yes, its been a challenge for many of us, including The Space Show. We all know the economic struggles faced by our nation and many of us at the individual level. Yet many of us see viable paths to solutions to our national and international problems running through the broad arena of space development and exploration. So please support The Space Show/OGLF by making a 2011 contribution to help maintain and further develop Space Show and OGLF programming, benefits, outreach, and services.

You can make your donation online using Pay Pal at either www.thespaceshow.com/donate.asp or www.onegiantleapfoundation.org/individuals.htm.  Simply click on the Pay Pal logo.  If you prefer mailing a check, please make the check payable to One Giant Leap Foundation, Inc. and mail it in care of me to P.O. Box 95, Tiburon, CA 94920 USA.  Remember that OGLF is a 501C3 non-profit corporation so you will get a federal tax deduction to the extent allowed by U.S. law.  OGLF is also a California Public Benefit Corporation so if you pay California taxes you can get a California tax deduction as well.  Please check with your tax advisor for the applicability of these potential tax deduction rules to your specific situation.

Your gifts make possible The Space Show programming, the free archives going back to the beginning in 2001, and the upcoming programming for 2012 and the future. It is your generosity that makes it possible to bring to all of you, on a global level, a wide diversity of topics, issue discussions, and guests from around the world.

Thank you for your support. I look forward to sharing the new year with you through The Space Show and the One Giant Leap Foundation, Inc.  Please contact me at drspace@thespaceshow.com if you have any questions.

Best Wishes and Sincerely,

Dr. David Livingston

Lesson Three Artificial Gravity, Tuesday, 5-3-11 May 4, 2011

Lesson Three Artificial Gravity, Tuesday, 5-3-11


Guests:  Classroom:  Dr. David Livingston, Joe Carroll, Dr. John Jurist, Dr. Jim Logan.  Topics:  Manned artificial gravity research station in LEO.  Please note that you are invited to comment, ask questions, and discuss the Space Show Classroom program/guest(s) on the Space Show Classroom blog, https://spaceshowclassroom.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show Classroom programming. This two hour plus Classroom program was continuous without a break.  For this program, refer to the Power Point presentation by Joe, “Design Concepts for a Manned Artificial Gravity Research Facility.”  Mr. Carroll took us through this presentation slide by slide, plus he responded to listener and co-host questions throughout the program.  You can find this presentation plus his longer IAC Conference paper on The Space Show Classroom blog under Presentation Materials for our Classroom program for May 3, 2011.  Rather than writing a summary of this program, let me say that Mr. Carroll has given considerable thought to the engineering and human factors/human physiology issues regarding an artificial gravity research station in LEO.  Listener questions addressed technical issues relating to spin, center of mass/gravity, hits by orbital debris items and more.  Throughout this Classroom discussion, Joe took us into the technology, operations, and why’s regarding his artificial gravity research station.  Many issues were discussed including but not limited to Mars & lunar gravity, .06 G, spin rates, the Coriolis effect, the Gemini experiments, a Moon/Mars Dumbbell Concept, Airbeam tunnels, radial structure lengths, and much more.  Toward the end of the program, we discussed the economics, costs, and who might pay for and deploy such a station.  You will hear Joe talk about the present economic, cost, and R&D uncertainties for such a project, but you will also hear him talk about the commercial potentials, who should be given “free” access to the research station and why, the use of it with Space X as well as Bigelow, and why not doing it as a NASA project makes sense though he advocated NASA as a customer.  At the very end, I asked Joe about building some small models to help those of us who are not engineers in understanding and even visualizing his concept.  He liked that idea, talked about larger models of the size of a Boeing 737 cabin (he used this cabin size throughout his discussion and presentation), and possibly locating it at a company such as Space X.  As we concluded our discussion, all of us said that after 50 years of human spaceflight, to not be able to answer any of the questions regarding the issues discussed in this program was criminal. Furthermore, as you will hear Dr. Logan and the others say, you can determine the credibility of a human space program by the speed and determination of the commitment to understanding the necessary gravity needs for people, plants, and animals in space.  If there is no commitment to understanding these issues, the program is more likely a rhetoric only program.  Post your comments & questions on the blog URL above. You can email Joe Carroll at tether@cox.net.  All participants can be emailed through me at drspace@thespaceshow.com.

Lesson Two Program, Advanced Depot Discussion, Tuesday, 4-5-11


Guests:  Classroom:  Dan Adamo, Jon Goff, Dr. John Jurist, Dr. Jim Logan.  Topics:  This Classroom program was an advanced in-space propellant depot discussion. Please note that you are invited to comment, ask questions, and discuss the Space Show Classroom program/guest(s) on the Space Show Classroom blog, https://spaceshowclassroom.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show Classroom programming.  We welcomed back our Classroom co-hosts Drs. Logan and Jurist and our two propellant depot experts, Jon Goff and Dan Adamo for a comprehensive graduate school level two hour discussion about propellant depots.  Also note that that as part of our upcoming Space Show webinar series, we did test video streaming during this program but as I said, we did not archive the video stream.  We will let you know when our next video streaming test will take place.  During our first segment, Dr. Logan set the tone with his opening statement when he said that resource pre-emplacement was essential if we were to go beyond LEO with chemical rockets.  Dan said the ISS was already a depot that transferred hypergolic bipropellant fuels.  This opened the door to cryogenic fuel transfer and a comprehensive discussion about boil off and the goal of reaching Zero-Boiloff Cryogenic Storage of the fuels in space.  Much was said about this, the energy needed to separate hydrogen and oxygen and why cryogenic storage was necessary in space.  We discussed some options were a depot to be located on the surface of the Moon but the issue of having sufficient power available for the separation is a significant one.  Launch windows, departure schedules, and depot locations were discussed.  We also talked about the idea of placing the depots in convenient places to attract multiple suppliers though this presents significant challenges with space traffic management problems.  In our second segment we started with a listener question about using NOFBX  and would it significantly help to reduce the complexity of a depot.  Jon Goff responded to this question.  Dr. Jurist brought up the issue of launch schedule reliability were it necessary to have between three to six flights including crew rendezvous happening within a specific time frame.  Both Dan and Jon referenced the Target NEO conference from February 2011, specifically the Chel Stromgren paper, “Getting to the Starting Line -Launch and Assembly Reliability for Deep Space Missions” (www.targetneo.org/Sessions/Session%203/TargetNEO-Session3-Stromgren.pdf).  During this segment, we discussed boil off rates and what this actually means regarding propellant losses and economic hits.  One of the recurring issues during our discussion focused on NASA Technology Readiness Levels (TRL). SpaceX heavy lift was discussed in the context of propellant depots as was heavy lift in general.  Bigelow hotels were also mentioned in the context of depots but there was also a discussion of why it might be too risky to put depots too close to human operated space hardware.  As our discussion was drawing to a close, our guests talked about the road forward. Each of our experts and our co-hosts provided short summary statements and as you will hear, each differed so don’t miss what each said.  We welcome your comments and questions so post them to our Classroom blog for this program.  If you want to email a specific guest, send your note to me and I will forward it to the person of your choice.

Lesson One, Introduction 2011, Sunday, 1-23-11


Guests:  Classroom:  Dr. David Livingston, Dr. John Jurist, Dr. Jim Logan.  Topics:  The Space Show Classroom introduction for 2011.  Please note that you are invited to comment, ask questions, and discuss the Space Show Classroom program/guest(s) on the Space Show Classroom blog,https://spaceshowclassroom.wordpress.com.  Comments, questions, and any discussion must be relevant and applicable to Space Show Classroom  programming.  The Space Show Classroom is back and this one hour program was our introduction to the 2011 semester.  Co-hosts Jim and John and I went through our suggested course outline which I will finalize upon my return from Grand Forks and post on the Classroom blog as soon as possible.  While we have a full agenda as you will hear, we are open to and we welcome your course and topic suggestions, as well as suggestions for possible expert guests for the Classroom programs.  Today, listeners asked us some detailed questions about radiation, solar flares, and a few of our suggested discussion topics, but this introductory program was more about letting everyone know that the Classroom has returned and what we will most probably be covering during the year., We also introduced a few new rules for the Classroom.  For example, we will not be using the toll free number for the Classroom this season.  There are a few reasons for this including the need for more phone lines when we do point and counterpoint discussions which we want to do more often.  In addition, we all thought that many of the listener phone calls last year took us off the Classroom main topic.  Remember, the Classroom is different from regular Space Show programs in that we do a two hour simulated graduate school course discussion and we need to stay focused and on topic just as in a real classroom.  The Classroom has its own blog per the URL above.  All Classroom shows are archived on The Space Show website, Gigadial for podcasting, and on the Classroom blog. They are not archived on the regular Space Show blog.  The Classroom blog is moderated and we do not post any comments or material not directly on point with Classroom programs and discussions.  If you want to contact the Classroom co-hosts, all of us have our email addresses listed on the blog.  Mine of course is drspace@thespaceshow.com.  One other Classroom rule we used last year and it seemed to work fine so it will be used this year as well is that all emails and comments about the programs or for the guests directed to me need to be posted on The Classroom Blog so everyone can see them and participate in the discussion.  If you do not post your comment yourself, I will post it on the blog under your name.  For the Classroom, we want to expand our discussions to as many markets and interested people as possible and one of the best ways to do that is to make sure that we have a variety of points of view on the blog along with quality discussions.  Finally, most all Classroom programs will be on a Sunday or Tuesday and just as we did last year, every Classroom program on the schedule, in the newsletters, and on archives will have “Classroom” at the beginning so these programs can be easily identified..  Thank you for participating in the 2011 Space Show Classroom series of programs.
