During the first segment, I asked Bill for a bit of his personal history going back to when he first started doing space news with UPI. Next, I asked him what over the years has impressed him the most regarding space activities. Don't miss what he had to say about this as multiple space events were on his list. In addition, I brought up the Planetary Society success with LightSail, their solar sail demo project. Bill talked about the mission, what is planned next for a larger, more lasting solar sail project, and the fact that The Planetary Society funded the $4.5 million cost from contributions by Planetary Society donors. Also in the news was the NASA "flying Saucer" which was really the demo of a new landing system for Mars using a huge (the largest ever) supersonic parachute 100' across. Bill went into detail on the mission, even how it got tagged a "flying saucer" which he said was the responsibility of the media. Listener Robert sent in an email asking for Bill's position on the Moon-Mars debate. Bill talked about benefits from both positions but did not share his personal preference as he wanted to stay strictly with reporting the news, not offering an editorial. That said, his discussion of the debate and the pros and cons of each side was most interesting. We talked some about planetary missions but honed in on New Horizons and Pluto. Also mentioned was the upcoming Europa Mission, then listener Carolyn asked him what he saw for human spaceflight over the next few years. Ben wanted to know if the private sector could take us back to the Moon. Bill had much to say about the emerging commercial industry but in the end suggested that the costs were so high along with very high risks that government would be the one to do it for a long time to come. Don't miss what he had to say about both costs and risks. Russia and their hardware issues came up, then we had quite a discussion on commercial crew, not fully funding it, and continuing to pay the Russians rather than getting the job done with American providers. John from Ft. Worth gave us a call to talk about the SpaceX subsidies for Falcon 9, wondering if the price of a Falcon 9 launch was the true launch cost or a subsidized cost. John and Bill had an interesting discussion on this with a few added comments by yours truly. John also used the time to repeat his position that going to the Moon was essential before going to Mars and that SLS was likely a place holder for labor and technology until we have a different space policy with different space leadership.

This will help me bring better programming to the audience. We welcomed Joan Horvath and Rich Cameron to the show to discuss their new book, "The New Shop Class: Getting Started with 3D Printing, Arduino and Wearable Tech," the importance of modern shop class training in our school systems, plus modern technology as a learning tool for students. During the first segment of our 1 hour 42 minute program, Joan explained why they wrote this book, the problem caused by the absence of shop class in schools around the country and the void their book attempts to fill. The book is targeted to both parents and teachers to assist them in being comfortable with the "new" shop class as the technology, the instruments & tools, and possibilities are totally different from the stereotype of a shop class from previous years. Joan talked about their pilot project with the Windward School in Los Angeles (see www.windwardschool.org) including the upcoming two day seminar August 14-15, Design and Maker Class Colloquium: Hands-on with Arduinos, 3D printing, Wearable tech (for details see www.windwardschool.org/design2015?rc=0). The book is also appropriate for students starting around the 7th or 8th grade but the Foreword to the book was written by a 13 year old student, Coco, who called the show. Coco was a most impressive caller who works this technology, has a keen interest in it, and I urge you to pay attention to her phone call. Coco was with us for most of the first segment. Additional topics discussed in the first segment included the use of Arduinos, STEM and STEAM, portable 3D printers, program funding, teacher and classroom issues. The portable Bukito 3D printer was discussed in some detail and even Coco told us how relatively easy it was to learn to use it. A few listeners sent in notes asking about how to get a new type shop class started in the schools their kids attend. Joan and Rich suggested starting small, work with kits, and use the open source world. It was also suggested that people attend a local MakerFaire or visit a hacker space though the latter may be challenging for students under 18. Jackie sent in a note asking about both wearable tech and implanted tech. Rich had some interesting comments on this topic, don't miss them. In the second segment, Joan and Rich talked about actionable things by both parents and teachers. Joan also talked about how students learn and the problems caused for some students when there is no shop class. She also said there was some parental push back so don't miss what she had to say about this. Randy from Tucson emailed in a question about traditional vocational training including the subjects Joan and Rich were discussing.Read the rest of the summary @ www.thespaceshow.com or http://thespaceshow.wordpress.com.

This will help me bring better programming to the audience. We welcomed back Dan Adamo to the show for this 2 hour 36 minute comprehensive discussion regarding HSF to Mars, the Second Mars Affordability and Sustainability Workshop report and much more. During the first segment of our program, Dan started out by telling us the process used to engage him reviewing said report and writing his critique of it which is on The Space Show blog (http://thespaceshow.wordpress.com). Topics discussed in this segment included the use of Low Latency Telepresence (LLT) as compared to High Latency Telepresence (HLT), the absence of human factors and aerospace medical personnel in attendance and said issues missing from the workshop report. Dan said the key missing information included radiation as well as microgravity concerns. Dan then questioned the existence of a compelling rational for humans going to Mars. This became a recurring discussion topic throughout today's program. Space settlement came up & so did a possible space race with China. The subject of a rescue mission came up but there was a detailed rescue mission discussion near the end of the program in the second segment. Dan was asked about the minimum crew size to operate an LLT program from Deimos or in orbit around Mars. Several emails were sent in including one by Dr. Jurist addressing high acceleration upon return from Mars. Dan then suggested the stepping stone approach, starting with cis-lunar space. Doug sent in questions about heavy lift versus using already large commercial rockets. Dan and Doug discussed this, then later in the second segment, Doug asked more questions on this topic. For now they talked about going to Deimos with a Falcon Heavy. Dan pointed out the need for many more launches and rendezvous missions as compared to one or two SLS type rocket launch. He questioned if we can't afford SLS launches, how do we afford even more launches and rendezvous missions. Marshal emailed us wanting to know about the possibility of lava tube plans . BJohn asked this guest about a possible Mars cycler & then we moved to the second segment. In the second segment, I asked Dan what he thought the impact on space policy might be vis a vis the workshop being discussed on this program. Don't miss his reply. Doug asked a question inquiring if for the same cost it would take to send humans to either Deimos or to the Martian surface, one could send many high-latency rovers to multiple locations far from each other to give the rovers many chances to discover evidence for life in different types of places? This brought us several exchanges comparing LLT with HLT, heavy lift versus smaller rockets and more. Read the rest of the summary @ www.thespaceshow.com or http://thespaceshow.wordpress.com.

This will help me bring better programming to the audience. We welcomed back to the show Greg Meholic to speak about advanced propulsion concepts, rocket reusability, and much more. During the first segment of our 84 minute program, Mr. Meholic first defined what he meant by the term advanced propulsion. Given this definition, we moved forward to discuss various concepts, propulsion methods, and propulsion research. During this segment, we talked about several propulsion technologies and Greg said thumbs up or thumbs down to their being advanced propulsion. When it came to nuclear, Greg classified it as an alternative propulsion method, not an advanced propulsion. Again, don't miss his definition. We talked near and intermediate term advanced propulsion concepts though it does not appear anything is really close at hand. His timeline for a possible advanced propulsion technology was around 20 years. He said not only do we need to understand the physics much better, but the propulsion method much compete with current systems and produce benefits including cost benefits. As far as choke points on advanced propulsion, he said understanding the fundamental physics involved was a big one. We then talked about funding which is now mostly from companies and other private investor oriented sources. I asked lots of questions about funding, especially how does one know when the point is reached to either kill the project or keep it going. Don't miss what he said about this. Listeners also asked many questions. In replying to one listener, he said it would be hard to beat chemical rockets to LEO but the door opens up BLEO though the Moon can be done with chemical rockets. When asked about the anti-nuke movement and the impact on the nuclear rocket, he had some interesting observations, especially regarding the views of younger people. When asked for leading advanced propulsion people and concepts, he mentioned former Space Show guest Dr. James Woodward and his work with Mach's Principle several times during our show. Greg was also asked about the work of Dr. Sonny White at JSC for warp drive and M drive. Greg had much to say about his work including Q thruster and M drive. John from Ft. Worth called in to talk about M Drive & Mach's Principle along with gravity and magnetic frequencies. In the second segment, Ashley sent in an email asking about going to the Moon and Mars for settlement and sustainability, wondering if advanced propulsion was needed for either location. You might be surprised by Greg's response to this question so listen carefully. He did say there would be different requirements for the Moon and Mars. With Mars, he also spoke about radiation and travel times. Read the rest of this summary @ www.thespaceshow.com or http://thespaceshow.wordpress.com.

John Batchelor and I welcomed back Dr. Alan Stern to discuss New Horizons which is now closing in on its flyby of Pluto after a nine year plus mission from Earth. We talked about the condition of New Horizons, the actual flyby, the collection of data and the transmission of the data back to Earth. We also discussed the Hubble Space Telescope findings about the strange tumbling of several of Pluto's five moons with data from New Horizons starting to confirm the Hubble images. Alan talked about the formation of moons in the Pluto system and said it was similar to the Earth-Moon formation. He said Pluto was the only other place in the solar system like our Earth-Moon system and it lies on the far outer edge of our solar system billions of miles from Earth. New Horizons is an exciting mission with lots to look forward to as the flyby happens and we get the data back from the satellite.

This will help me bring better programming to the audience. We welcomed back Dr. Robert (Bob) Zubrin to discuss the upcoming Mars Society Convention in Washington, DC from August 13-16, 2015 (see www.marssociety.org/a/marssociety.org/www/conventions/18th-annual-international-mars-society-convention). During our 1 hour 45 minute program without a break, Dr. Zubrin not only told us about the upcoming Mars Society Convention for 2015, but talked about Human Spaceflight (HSF) to Mars by addressing many specific issues, concerns, and topics. Starting off with the Convention, it is August 13-16, 2015 at the Catholic University of America in Washington, DC. Special hotel prices are available at the Phoenix Park Hotel (see www.marssociety.org/conventions/18th-annual-international-mars-society-convention/hotel-and-transportation for reservation details). Bob told us about the keynote speakers but also the special format this year for debates. Several topics will be debated including Moon vs. Mars, Mars One feasibility with the MIT team and Bas from Mars One, how best to achieve commercial space plus other topics. Bob then started getting questions from listeners & myself on a wide variety of Mars HSF mission topics. To start with, I asked Bob to comment on what several recent Space Show guests have said about our not being ready for HSF to Mars for a variety of reasons including radiation, other human factors, the costs, and the trip risk which would turn it into a survival mission and nothing more. Before Bob responded to my specific question, he commented on the recent radiation paper, "How a trip to Mars would mess with your brain." Bob was very critical of this paper and spent time going through it and showing where he believed it to be bogus. You can read Bob's critique at www.marssociety.org/home/press/announcements/invalidclaimsmadeforwhathappenstoyourbrainonthewaytomarspublication. Bob spent a good amount of time debunking the original article so don't miss his comments. Before moving on, I again asked Bob to respond specifically to what my guests had said as none of them mentioned the paper in question. We had an interesting discussion on risk taking and the role of government as part of our discussion. John in Florida called to ask about the concept of a nuclear explosion on Mars per Space Show guest Dr. John Brandenberg. This led to questions about shortages of PU238, space policy & political leadership. Doug had questions about an Earth Return Mission and later he eventually called in to get a more precise answer to what he was asking. We talked about one way missions, how best to explore Mars, and the responsible way to tackle the eventual settlement on Mars.

This will help me bring better programming to the audience. We welcomed Dr. Erik Seedhouse back to the show for a variety of timely discussion topics. During the first segment of our 1 hour 37 minute program, Erik started out making comparisons with past polar exploration and going to Mars. He also said that going to Mars anytime in the foreseeable future would be a survival trip. We talked about Erik's books on Virgin Galactic, Polar Exploration and Mars which will soon be released, and additional books on Dragon, Mars One, Mars via the Moon, and XCOR, all to be released over the coming months. Erik then spoke about his ISDC talk re comparing polar exploration to going to Mars and commented on the speaker following him, Dr. Logan (he was not sure of the first name but we think it was our friend, Dr. Jim Logan). He talked about radiation shielding and water per what Dr. Logan had to say including the need for 10 meters of water shielding to equal the protection here on Earth. Erik had much to say about radiation and shielding which prompted multiple emails from Dr. Doug in S. California seeking clarification and adding to Erik's comments. I read all of Doug's radiation themed emails throughout the first and second segment of today's program. Don't miss Erik's conclusions regarding the radiation risks and shielding needs for a Mars mission, how astronauts would live and work on Mars as well as the Moon. Erik next talked about Virgin Galactic and XCOR saying he thought XCOR would be the first to fly commercially. When asked about the biggest passenger risk on a suborbital flight, Erik said it would be the cardio-vascular risks. Erik got questions regarding SpaceX, Elon Musk, and the Mars Colonial Transporter. He again stressed the way to go to Mars was via the Moon and that would be his preferred space policy. He also put forth his Mars simulation study plan. Don't miss it, I think it’s a good one. In the second segment, John from Florida called to comment on delays and how long commercial suborbital flight was taking since the success of Spaceship 1. John seemed to compare the lack of progress with suborbital flight to how much progress was made with aviation and in particular jet travel. I took the first pass at responding to him, then Erik offered his comments. What do you think? Let us know on the blog. Erik was then asked about other human factor issues than radiation. Dr. Seedhouse went through a laundry list of health risks and concerns for astronauts in deep space and on long duration spaceflight. He was then asked about the regulatory regime for suborbital space, then he wanted to define space given Virgin Galactic may not flight beyond 50km which is not space.

This will help me bring better programming to the audience. Welcome to our final Open Lines program for May 2015. During the first segment of our 1 hour 46 minute program, I threw out some suggested topics for discussion including Space Show website changes, our planned crowd funding project for financing the new website, a satirical article in The Onion, "NASA Announces Bold Plan To Still Exist By 2045" (see www.theonion.com/article/nasa-announces-bold-plan-still-exist-2045-50398), and the possibility of the government regulating lunar and asteroid mining plus other topics as well. Tim from Huntsville was our first caller. He misunderstood my comment about The Onion article and wanted to know what bold plan NASA was announcing for 2045. I clarified the matter with him but he still seemed to think the article had more to do with the reality of NASA today rather than just a comedy article in The Onion. I disagreed with him but he did say that space policy based on a two term administration and then changing was not productive and should be changed. Later in my conversation with Tim I mentioned an LA Times article by Jerry Hirsch which was highly critical of Elon Must for taking government subsidies. Little did I know that this article would be the hot topic of the day on this Open Lines program. The actual article, "Elon Musk's growing empire is fueled by $4.9 billion in government subsidies" can be read at www.latimes.com/business/la-fi-hy-musk-subsidies-20150531-story.html#page=1. As I sated on air with several callers and emailers, I thought the article was incomplete and a hit piece since it ignored the basic economic facts of government non-cash subsidies. Dennis Wingo called in to refute the article though Kelly Starks emailed us in support of the main theme of the article. During John's call from Florida, I was asked to see if the article's author would come on The Space Show. I commented that I was probably not that interested in talking to him and noted my experience with general audience journalists (not all of them) as compared to talking with space journalists. In the meantime, Marshall called to chime in on the presidential cycle and space policy and what it means for long term space projects. We did note several projects that have survived through various administrations such as Hubble, many of the planetary science missions, SLS and more. In the second segment, Tom, a first time caller to the show from Seattle, wanted to talk about his view of the space industry being immature. By immature, he meant that doing only a hundred or fewer launches a year and not that much new being done in space indicated being immature to him.

This will help me bring better programming to the audience. We welcomed Dr. Ian Crawford to the program to discuss his work and paper "Lunar Resources: A Review." This paper can be found on The Space Show blog for this date and show, http://thespaceshow.wordpress.com. In addition, Dr. Haym Benaroya co-hosted the program with me. During the first segment of our 1 hour 20 minute discussion, Dr. Crawford explained the motivation behind his research plus I asked him about any surprises he came upon during his research. Two areas that surprised him included Platinum Group Metals (PGM) and helium three (HE3). He referred to HE3 several times but he discussed it in more detail in the second segment so I will defer until then. We talked at length as to why the Moon was of interest. He talked about the scientific value of the Moon as well as learning how to do things in space that we will need later on gong to Mars or other destinations. He said the Moon was resource rich but that we were only beginning to learn what we can do on the Moon and how to benefit from its resources. Both our guests were asked if we were nearing the maximum point of benefit for remote sensing lunar operations. The answer was yes but we were not there yet as more improvements in HD resolution and other areas are yet to be realized. That said, robotic lunar exploration is now available as is human exploration. Both Haym and Ian said the format for lunar exploration would likely need to be public private partnerships, even with international missions. They also said we need to start doing it now. Haym said it was a bootstrap type of process and Ian said it was a learn as you do process. On the job lunar training! Haym also mentioned that 3D printing and robotic systems would lead the way before humans. He also suggested they might evolve to the point that they can do construction so astronauts going to the Moon do not have to be "construction workers." As the segment was ending, Ian was asked about the needed legal infrastructure to commercialize lunar resources. He had much to say about this before the segment ended. As the segment was ended, an 11th hour question was asked about making rocket fuel from water ice & could we do it today. In the second segment, Doug from S. California called & wanted to know if there was any resource needed for settlement on the Moon that was completely lacking or unavailable on the Moon. Ian said it was a complicated answer given that a resource might be there but the needed energy to use it might make it impractical. He said for a long time to come we would be making things on Earth and importing Earth products to the Moon but as Haym said earlier, it would be a bootstrapping and learn as you go and do process.

Please note that audio and transition issues are a result of copying the John Batchelor broadcast & are not within my control as they originate in the Batchelor studio.John Batchelor and I welcomed back Marcia Smith of spacepolicyonline.com to discuss the NASA 2016 budget per the recent decisions made by the House Appropriations Committee. We discussed SLS, Planetary Science, Orion, Commercial Crew, cuts to Earth Sciences plus the criticism against these allocations by both The White House and NASA Administrator Charles Bolden. We also talked about Mr. Bolden's comments saying that if commercial crew were not fully funded, it would seriously delay the program. While the committee allocated a larger amount to the commercial crew program than before, it did fall short of what both The White House and NASA said the program needed. We also talked spending caps and sequestration. Marcia explained how that would work as overall the total spending for the agencies involved have to stay within the caps but the allocations within the agencies can differ which is why there are winners and losers. John questioned Marcia on SLS as he was not that supportive of it. Note what Marcia had to say about SLS but whatever one thinks about it, the program clearly has the support of many in Congress. You can email Mr. Batchelor or Marcia Smith through me or her website.
