During the first segment of our 1 hour 56 minute discussion, Bob started out with an historical overview of the progress made in developing the commercial space industry, a U.S. cargo capability to the ISS, and eventually the U.S. capability of carrying astronauts back to the ISS. He started his timeline in 2004, specifically addressing the time since President Obama came to office. For almost the entire first segment, Bob noted milestones, progress, company developments, the beginning of competition and much more. Later in the segment, he mentioned what he said was the lack of progress in the suborbital industry during the time period he had been talking about and suggested that the suborbital companies may be missing parts of the market given their continued delays. He talked about this in more detail during the second segment. He also talked about human spaceflight (HSF), SLS, Falcon and SpaceX as a game changer, the efforts of Sierra-Nevada to continue on with Dream Chaser, & his opinion that it will likely be the private sector that manages HSF to the Moon and Mars rather than a public program. We talked about public opinion and space, then Marshall called to ask questions about China, their space program, plus a possible Chinese impact on our space policy. Bob had much to say about the Chinese program, then he had about an equal amount to say about the Russian program. Sylvester emailed in to also ask about China, specifically if Bob thought we would soon be cooperating with one another in space. Bob seized this opportunity to make it very clear as to why he disliked international partnerships, instead preferring competition. Before the segment ended, Beth asked Bob for his thoughts on the Moon-Mars debate. In the second segment, Kristen started us off talking about LightSail. Bob had much to say about the mission, The Planetary Society, how it was funded, and the fact that it was based around using cubesats. He then spoke to the success of cubesats and how they are changing aspects of the industry. Bob jumped to Comet 67 P, the Rosetta mission and the Philae Lander. He used this opportunity to provide an overview of planetary missions starting in 1957. In talking about the success of planetary missions, he mentioned the Dawn mission to Ceres and Vesta plus many more. I asked Bob about New Horizons and Pluto. Bob had much to say about Pluto, its moons, & specifically the moon Charon. Other topics that came up as we neared the close of the show included the Europa mission and an effort to use crowd funding to make a porno film in space.

We welcomed back Randa and Rod Milliron of Interorbital Systems (www.interorbital.com) for news and updates since their 2014 Space Show appearance. During the first segment of our 1 hour 28 minute program, Randa and Rod updated us on their launch license application process as they just returned from starting the process with the FAA AST office. They also attended a ride share conference at the Applied Physics Lab which they talked about. We talked about launch sites, the EIR needed for their launch license, and other issues relevant to getting a launch license. Our guests mentioned they were planning both land and sea launches. We talked more about the ocean launches in the second segment of the program. Our guests described their test launch program, then we talked about their satellite kits, both the TubeSat kit and the CubeSat kit. We then received a call from one of the Interorbital customers, Barbara at Boreal Space (www.borealspace.com). Following Barbara's call and her take on being an Interorbital customer, Randa talked about their Guidance System test program and upcoming test flight, then Jack sent in an email asking them for time lines on their launch manifest. You can see the Interorbital launch manifest at http://interorbital.com/interorbital_05022015_014.htm. We talked about the capabilities of their satellite kits once the TubeSat or CubeSat made it to orbit as Kristine asked what these small satellite can do. Next, the Interorbital orbital plans were discussed as were the company suborbital plans. Jake in Dallas inquired about their suborbital to orbital plans using their modular rocket system. Don't miss what our guests had to say about this. Randa then brought up their space rescue and suit design program featuring Olaf Spitzer jumping from space off of one of the Interorbital rockets. Our guests had much to say about this planned jump, especially when they compared it to the recent record holding balloon jumps. Near the end of the first segment, questions came in about 3D printing and rocket reusability. In the second segment, Tim called to ask about the cost to make each modular rocket, wanting to know if they could make a profit given these costs. Our guests said actual costs were proprietary but they did say they would price their orbital launch at $1 million for 30-50 kilos to a 310 km orbit. Tim also wanted to know how Randa and Rod got started in this business, plus he wanted to know if crowd funding was a good way to go. They supported crowd funding but said it might not be a good method for starting up a launch business. Don't miss their comments on this subject.

For those listening to archives using live365.com and rating the programs, please email me as to why you assign a specific rating to the show. This will help me bring better programming to the audience. We welcomed back space attorney Michael Listner to discuss the importance of the U.S. National Space Policy, both nationally and internationally. Please refer to the document Michael prepared for this show which you can find on The Space Show blog, "NATIONAL SPACE POLICY A PRECIS OF FUNDAMENTALS & PURPOSE." Michael's document is essential to understanding the significance of our national space policy, both on the home front and internationally so don't skip over it. We used it extensively during our discussion as Michael used the exact policy language in his document to make his points. During the first segment of our 2 hour 2 minute show, Michael explained the origins of this show given my challenge to him from a few weeks ago to tell us why national space policies are important given that many of us, myself included, just view them as political rhetoric or something like that. Michael did a fantastic job of connecting the dots from back in the beginning with President Eisenhower through to President Obama, showing us the evolution of commercial/private space and much more. He also connected the dots on why our national space policy is significant on the global scene. Here, he used the definition of space as an example. After you listen to this program and read Michael's paper, you will have a very clear understanding of the emergence of the commercial space industry as it is today, including government subsidies, plus many other parts of our space program, including the national security space program. During this segment, we went through the presidents starting with Eisenhower to see how each new presidential national space policy helped to create the legal and policy structure of today's space industry, public and private. Michael explained policy from both the global view and the geo political view, again connecting the dots for us to what is happening in the space industry today. He was very clear in showing how the birth & development of SpaceX for example, was due in part because of our space policy and the laws congress enacted to support the goals of our national space policy which included private space and later on, even government subsidies. In the second segment, we started taking more listener questions. Carl asked who actually creates the Presidential National Space Policy. Barbara asked if space property rights could be established through our space policy. This prompted another excellent discussion by Michael on the subject. June asked about our space policy enabling tourism and even visits or settlements on the Moon or Mars. Read the rest of this summary @ www.thespaceshow.com or http://thespaceshow.wordpress.com.

For those listening to archives using live365.com and rating the programs, please email me as to why you assign a specific rating to the show. This will help me bring better programming to the audience. We welcomed Dr. Bruce Damer back to the show to discuss his two new TEDxSantaCruz talks regarding sustainable space exploration and new theories on the origins of life. Watch the first of his two TEDx talks on sustainable space exploration at www.youtube.com/watch?v=wLMHcUg36yc. His second TEDx talk addressing new theories on the origins of life can be viewed at www.youtube.com/watch?v=6qiW4aUqtvA. In the first segment of our 1 hour 28 minute discussion, Dr. Damer introduced us to his concept for sustainable space exploration, including round trips to Mars. His spacecraft is the S.H.E.P.E.R.D which he fully explained with great animation in the TEDx talk. This is a method for capturing and enclosing a small but valuable asteroid between Mars and Jupiter, using a chemical process to mine it for volatiles and to fill special tanks with the volatiles and return the cargo to where it is needed, Mars, the moons of Mars, cislunar space, the Moon, or an orbiting space station. Bruce spent the first segment of our program discussing this technology and the concept, plus explaining how it can be used to facilitate and enhance human spaceflight including human exploration of the solar system. The YouTube video is just under 10 minutes so be sure to watch it. Listeners asked him many questions to fully understand the concept so the YouTube talk and his Space Show discussion go hand in hand with one another. In the second segment, Bruce as asked about the cost to develop, launch, and operate S.H.E.P.E.R.D for a humans to Mars mission. Bruce did not have costs available but used the Rosetta Mission as an approximate guideline for estimating costs. Also in this segment, he noted the use of inflatables in space and the long history of success in using them back to the early days of the space age and the Echo communication satellites. He also referenced Genesis 1 and Genesis 2 on orbit through Bigelow Aerospace. He then said that inflatables would be safer for humans due to less radiation. Don't miss his comment on this issue. Bruce then talked about water and shielding. As the program was nearing its end, Dr. Damer discussed the second TEDx talk regarding new theories on the origins of life. He also connected the dots for us with both talks so don't miss what he had to say. By the way, the sustainable space exploration talk opened the TEDx session and his origins of life talk was the closing talk at the event. Toward the end, he talked about outreach with his new idea and said he would be giving a FISO talk on S.H.E.P.E.R.D June 24 so those of you who listen to FISO talks be sure to catch this one live or on archives.

This will help me bring better programming to the audience. We welcomed Bill Harwood of CBS Space News back to the show for this 80 minute discussion. 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.

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.
