We welcomed Dr. Wendell Mendell back to the show for this two hour discussion (no break) about his 50 years at NASA JSC, lunar bases, commercial space, return to the Moon, the value of the Moon, our space program, space advocacy, commercial space, and lots more.  Dr. Mendell came to work at JSC in 1963 &will be retiring at the end of this year, culminating 50 years at JSC.  During our discussion, Dr. Mendell used lots of stories from his NASA and lunar base work experience to illustrate issues with space policy, NASA, our Congress, and space advocacy, & advanced technology.  Listeners had lots of specific questions for Wendell about lunar bases, water on the Moon and its commercial exploitation, commercial lunar programs, and NASA having a lunar program which Dr. Mendell said it did not.  Dr. Mendell spoke to some of the NASA organizational issues, congressional micromanagement issues and problems, and the nation’s overall economic problems as a reason for not doing this or that in space.  He cited such economic problems as a rational excuse for not doing something meaningful in space in almost every year of his 50 years of NASA experience. The same for threatened, proposed, or even real NASA budget cuts.  Later in the segment when caller Doug called in with his lunar water and development ideas, Dr. Mendell pointed to conflicting LCROSS analysis as to water being on the Moon. Russian instruments do not say the same thing as the Los Alamos instruments and he said this was & still is a hotly debated topic in the lunar community.  As Doug continued talking about his plan, Dr. Mendell backed him up, took him step by step through the process of accomplishing his many goals. This turned out to be a very valuable instructional discussion that all of us can and should benefit from.  Make sure you hear how Wendell breaks down Doug’s points to show the complexities and challenges of each incremental step in what Doug was proposing.  Our guest even showed Doug where some of his steps needed commercial technogly which does not exist! Doug’s rocket of choice is the Falcon Heavy, a rocket which does not yet exist, nor does it have real numbers behind it.  Wendell used this discussion to distinguish true believers from investor and commercial analysts.  He then said when the believer is also able to bring his own money to the venture, things can get done and he cited SpaceX as an example.  Later Doug asked by email if NASA could help private companies develop cislunar transportation as they have helped private companies provide launch services to LEO/GEO. The simple answer was yes but make sure you hear Dr. Mendell’s complete answer to this question.  Another issue discussed was the needed timeline to do a human Moon mission. Wendell described the times of Apollo as compared to the times of NASA today.  We talked about the importance of a better and different NASA and RTM story and again, Dr. Mendell illustrated his points with stories from his past experience.  Spanning 50 years of history and experience was not easy to do in even a two hour Space Show program. As you listen to the program, you will hear many more subjects, stories, and issues discussed than stated in this summary.  In the end, I believe NASA, our nation, and the effort to develop space has been served incredibly well by Dr. Wendell Mendell and his creativity, his drive, his analysis, his commitment, and his work will be genuinely missed by all.  The Space Show wishes Wendell all the best for his coming retirement, gives him a hearty THANK YOU for his service, and we will remain in contact with him and hope to have him back with us at a future time.

http://thespaceshow.files.wordpress.com/2012/11/adamo-eml2roundtripr2.pdf.  We welcomed Dan Adamo back to the program and Dr. John Jurist as co-host for this special webinar addressing trajectory analysis for an EML2 mission and more.  On The Space Show blog, you will find Dan’s PDF document used during the webinar, a link to the movie he played in the second half of the webinar, and his Phobos-Grunt analysis paper we discussed near the end of the webinar. During the first hour of the webinar, Dan took us through the trajectory analysis to Earth-Moon L2 per his PDF document.  We talked about why EML2, libration points in general, and how such missions are planned.  If the resolution on the webinar video for the charts and tables used during this segment are difficult to read on your computer, please bring the document up on the PDF on The Space Show blog and follow along that way.  Dan took us through Table 1, HALO orbits, and the HOI as well as the Trans-Lunar Insertion points.  We talked about orbital characteristics, delta V, rocket size, and more  We also talked about the position of the Earth, launch windows, the Moon, & other factors influencing the planning of the mission.  While at times the discussion may seem a bit technical or overwhelming for those of us having never done mission planning at this level before, all of us will certainly have a better understanding of the factors considered and influencing both robotic as well as human spaceflight missions.  Near the end of the segment, we talked about the SLS and heavy lift & how payload capacity interacts with mission & trajectory analysis. 
 
     In the second hour of our webinar, Dan took us through his HD movie of the orbital trajectory talked about during the first segment, stopping it at intervals for specific explanations and questions.  The movie is in the QuickTime format but you can see it both on the webinar or by using the URL provided on the blog.  We took several listener calls & questions.  One asked Dan about the differences in planning for the robotic vs. the HSF mission using MSL & Curiosity as an example.  Dan pointed us to a YouTube video he made a few years ago with Dr. Logan using these tools for a Deimos mission (www.youtube.com/watch?v=X10GAqA4Ky4). Another listener called wanting to know the likelihood of an EML2 mission actually happening.  Dan explained why he believed this mission to be the next stepping stone in HSF.  More was discussed about SLS with Dan raising some concerns about its real capabilities & wondering if Congress is being sold unrealistic expectations. We talked about heavy lift in general & with the support of properly placed depots.  SLS and the difference with a Falcon Heavy were also discussed in terms of what the differences would mean in payload, number of launches, costs, risks, etc. 
 
     Please post your comments/questions on The Space Show blog.  You can contact either guest through me.

Cislunar Space Development

http://archived.thespaceshow.com/shows/1876-BWB-2012-10-19.mp3

Guests: CLASSROOM:  Dr. Paul Spudis, Dr. Jim Vedda.  Topics:  Cislunar space development and economics.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blogs, http://thespaceshow.wordpress.com and the Classroom blog, http://spaceshowclassroom.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Written transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We do not permit the commercial use of any Space Show program or part thereof, nor do we permit Space Show programs to be edited, placed on YouTube or other private channels & websites. Space Show programs can be quoted in news articles, papers, academic & research work, but must be cited or referenced using the proper citation format. Contact Dr. Livingston for questions about our copyright and trademark policies which we do enforce.  For this Classroom Space Show two hour program, we welcomed Dr. Paul Spudis and Dr. Jim Vedda for a comprehensive discussion on the importance of undertaking Cislunar space development as a major focus of U.S. space policy.  Our program was in two equal segments but since our topics crossed segments, our summary will reflect the entire program, not each segment.  Also, at the end of this summary, I have listed several relevant URLs for cislunar space development and our guests.  If you want more information on the subject, I suggest you visit the recommended websites and blogs.  Our guests described cislunar space for us and did an excellent job in letting us know why it is important to focus on a cislunar space development program.  In the process of addressing this very important issue, we talked about policy, the railroad model, the need for space infrastructure, insitu resource development and understanding, lunar water, lunar ice, lunar polar robotic exploration, the need to learn to live and behave in space, and much more.  Listeners called and asked email questions that drew out both our panel members so that our discussion was sufficiently thorough.  Side issues were discussed such as budget cuts, tight budgets, how to do cislunar space in a belt tightening environment, small businesses and contractors, even sequestration.  Our guests were very clear as to why cislunar development was much more preferable than “space stunt accomplishment” types of programs and projects.  Our guests presented a good case in letting us know why cislunar development is preferable over a humans to Mars mission at this time. Another issue brought up by a listener was to ask about “Plan B” if for some reason there was no water or there was insufficient water/ice on the Moon.  Dr. Spudis explained why that was not likely but both panel members talked about why cislunar development was important to even without sufficient water/ice resources on the Moon. Here are the URLs of interest I mentioned above:  First, Dr. Vedda’s new book, “Becoming Spacefarers: Rescuing America’s Space Program” is at www.amazon.com/Becoming-Spacefarers-James-A-Vedda/dp/1477130918/ref=onegiantlea20.  The Paris conference mentioned by Dr. Spudis is the ASTECH’s “Developing Space” Conference is at www.d-space2012.com. Dr. Spudis websites and blogs can be found at www.spudislunarresources.com; www.spudislunarresources.com/blog; http://blogs.airspacemag.com/moon.  His book, “Blogging the Moon” is at www.amazon.com/Blogging-Moon-Paul-D-Spudis/dp/1926837177/ref=onegiantlea20.  Other related websites of interest include www.spaceref.com/news/viewpr.html?pid=13404; www.spaceref.com/news/viewsr.html?pid=19999; www.spudislunarresources.com/Papers/The%20Vision%20and%20the%20Mission.pdf.; www.cislunarnext.org.

James Schier, Sunday, 8-5-12

http://archived.thespaceshow.com/shows/1829-BWB-2012-08-05.mp3

Guest: James Schier.  Topics:  U.S. space policy, NASA and human spaceflight goals, hardware, programs, and upcoming test flights, commercial space development. You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed NASA’s James Schier to the program to discuss the future of human spaceflight.  As the NASA Chief Architect and Planning Systems Manager plus a team member of the NASA Commercial Space Team, Mr. Schier spent two hours with us discussing our human spaceflight programs & future in detail.  In our first segment, we started back at the Columbia accident when a year later, it was announced that we needed a “bold new approach” to our HSF program.  Constellation was being developed, we changed administrations and then the Augustine Commission concluded that either NASA needed more funding to accomplish the program in place or it had to be stretched out if the budget remained the same or shrunk.  A flexible path was adopted and funding was left as is.  Our guest said there were three goals of the program including private sector development & participation in our HSF program, operating a fully developed & functioning ISS to 2020 and possibly beyond, & implementing a crew flyby of a NEO around 2025 with a humans to Mars mission around 2030.  This was the flexible path with a multi-program approach.  Our guest talked about the ISS becoming fully operational as an exciting national lab and he received several listener questions asking him why so many have said or written that our space program is at best in a state of confusion & at worst in a state of deterioration as we were not hearing anything like that with our guest.  Don’t miss this important discussion.  When Jim talked with us about SLS, he got similar listener questions that differed from what we were hearing about the program, the commitment to it, and its progress. Again, don’t miss what our guest had to say about the SLS program, its mission, capabilities, & the ongoing planning with the project.
In our second hour, we took a call from John about SLS as well as the program being more a congressional program rather than the President’s program.  SLS was compared to the cancelled Aries V, then we talked about the biggest risk to the program, ongoing congressional support & funding. Jim talked some more about Orion heat shield testing and reentry speeds, plus the upcoming heat shield test flight. Other Orion & SLS test flight programs were reviewed in this segment.  Listener Terry wanted to know if Orion could be flown on the Falcon 9 Heavy if SLS got cancelled.  Dr. Rowe called in to talk about specific cardiac stress issues for the returning astronauts. Mr. Schier then summarized many of the human spaceflight medical challenges facing us as we move out toward a lunar base, NEOs, and Mars. In this discussion, our guest did say that so far they were not seeing any show stoppers for extended long duration human spaceflight.  Near the end of our discussion, we talked about future missions under study, deep space habitat elements & large in-space transportation systems plus faster space travel with nuclear & possibly solar propulsion.  Standardized docking issues were mentioned along with international cooperation, citing the importance of the Russian support after the Columbia accident, highlighting the need for diverse crew space transportation.
Please post your comments/questions on the blog.  You can email Mr. Schier through me & I will forward your note to him.

Dr. Paul Spudis, Sunday, 6-24-12

http://archived.thespaceshow.com/shows/1803-BWB-2012-06-24.mp3

Guest:  Dr. Paul Spudis. Topics:  Return to the Moon, lunar ice & water, space policy, NASA space program.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed Dr. Paul Spudis back to the program.  Visit his website and blog for additional information, www.spudislunarresources.com & http://globs.airspacemag.com/moon. We started out by discussing a new report claiming that there is a low amount of water ice at Shackleton crater on the Moon.  Dr. Spudis explained this study/report and introduced other data points indicating the low amount of water theory is not a valid conclusion.  This discussion led to questions about science & media reporting and how best for the public to follow up on a story to not be mislead.  I asked Paul about the influence of such articles on policy makers and congressional staffers as well as those outside the U.S., citing the Chinese space program as an example.  I also asked our guest if we were in a space race with China. Dr. Spudis had much to say about this issue.  We talked about why American space leadership on the space frontier is important.  See if you agree with what our guest had to say on this important subject.  Dr. Spudis then talked about the difference with a PR stunt type of mission as compared to a mission which developed & enabled capabilities to move us forward in space development, exploration, and economics.  This brought up a June 20, 2012 Space News op-ed (http://spacenews.com/commentaries/120618-administration-legacy-nasa.html) by Frank Van Rensselaer, What Will Be This Administration’s Legacy for NASA?  This then led to a discussion about our not having a space vision direction or strategy for our civil space policy.  Much was said about this with callers and email questions during the balance of the first segment and throughout the second segment.  Our guest made a point of saying we need to ask what the purpose of the mission is, what are the goals, and what is the value of the mission?  These are important questions to always ask about what we are doing with our civil space missions.  This is an important discussion so do listen closely to what Dr. Spudis had to say.  NASA budget issues were part of this discussion with Dr. Spudis making the case that money was and is not really the issue.  Instead, its the politics of how we choose to spend tax payer money.

In the second segment, Marshall called to ask about lunar lava tubes and water, along with the need for lunar rovers.  Don’t miss what Paul had to say about these topics.  Paul was asked about his cislunar economic plans and he talked about NewSpace given the question he received from Wayne in Las Vegas asking him if he was in conflict with NewSpace.  Later, Crystal from Tulsa emailed Paul with a question about space property rights. Paul said this was extremely important so do listen to the complete discussion on this topic.  More was said about NASA budget issues & making sure taxpayers get something back for what they spend on space.  Andrew sent in an email addressing the technology development problems going back decades with military airplanes & large engineering projects.  Near the end of our two hour program, Dr. Spudis mentioned the tyranny of the rocket equation and what this means for space access and costs.  We also talked about on orbit fuel depots.  Reaching a critical mass for making a difference in space policy was our last discussion topic.

If you have a comment/question for Dr. Spudis, please post it on The Space Show blog.
