In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed Dr. Pascal Lee back to the program to tell us about The Northwest Passage Drive Expedition, what they learned that can be useful for crews going to the surface of Mars, including how to select a Martian crew and more. A documentary film, "Passage To Mars," was made of this expedition which we also talked about. During the first segment of our 90 minute discussion, Dr. Lee talked about the infrastructure needed for the expedition including vehicles, supplies, and the terrain that they would be traveling across. Several times during this segment as well as the second segment, he stressed the need for two vehicles in case one got stuck or had a breakdown. The expedition used specially equipped Humvee's. Pascal also talked about the fact that it took three seasons to complete the expedition. Our guest described traveling across sea-ice which was surface used by the expedition. Listener Jack asked Pascal how similar the expedition terrain was to Mars. Our guest said that Mars was more dangerous and confined. For example, the Northwest Passage Expedition did not travel in a lethal environment but there were also some similarities. Pascal talked about how Mars was more treacherous and why. Ben asked about radiation since traveling far north on Earth exposes people to higher doses of radiation. Our guest had much to say about this topic, measurements taken at Devon Island, and areas on Mars where Curiosity has show not so much radiation but then other areas on Mars where the cosmic rays mix with the Martian soil with hydrogen for much greater radiation levels. Listener Carl asked about crew issues. Pascal listed five standards that should be considered when selecting a crew, even for Mars. I suggest you make note of the five standards as we will be talking about them on future Space Show program. In the second segment, our first question came from Mohammad in Amman, Jordan inquiring about Pascal reaching out to other Mars advocacy organizations and individuals to do scientific research on their expeditions and missions. Pascal had much to say about this, especially in support of SpaceX and Elon Musk and just the opposite with Mars One. Don't miss all of Pascal's reply to Mohammad. Linda wanted to know about lessons learned and applying them to the Martian moons. Pascal was a big supporter of going to the Martian moons first so be sure to listen to what he had to say about this subject. He did say going to the Martian surface was a tall order. Pascal mentioned that there were about 50 sites being considered for the first Mars human landing site. I asked him how planetary protection might alter these plans. This caused our guest to tell us about the microbiology study that they did regarding possible contamination on the expedition. They published there findings in the June issue of Astrobiology.

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed Patrick (Pat) Host to the program to discuss national security, defense, and military space. We started our 1 hour 47 minute discussion with a first segment that focused on the RD180 issue. While we have talked about it before, Pat provided us a different perspective for this thorough discussion which also went into civil space and issues over competition. You do not want to miss this discussion. Pat also talked about the main players on both sides driving the RD180 issue. Another topic covered in the first segment focused on protecting our existing space assets, including cyber issues and essential cyber protection. Our guest had much to say on this topic, including DoD priorities. Several listener email questions came in. Ben from Boston wanted to know about national security launches and SpaceX. Our guest supported multiple launch providers but listen to his comments for detail. Another listener asked about DOD and the potential threats posed by Iran and N. Korea. Unfortunately, our guest was not able to offer us much on this topic. For the second segment, note that there was an editing glitch as the segment started. I did pick up on the glitch quickly but could not restore the first few minutes. However, when I realized what had happened, I asked Pat the initial question over again so you did not miss anything despite the glitch. My apologies for this as the mistake was on me. That said, we started the second segment with Pat telling us about Rep. Jim Bridenstine from Oklahoma wanting more accountability for DOD and more. Our guest referenced the American Space Renaissance Act. Read about the Act which was introduced at the recent Space Foundation Conference in April at Colorado Springs, http://bridenstine.house.gov/space/?postid=710. I urge you to become familiar with this proposed legislation which covers national security, civil, commercial, and military space issues. I'm sure we will hear much more about it as time goes on. Satellite communication issues were discussed in this segment as they are very important and key for national security space and the Air Force. Pat did a good job of putting these issues in focus for us, helping to understand them and their importance. Richard Easton called to talk GPS OCS and GPS 3. This was a good exchange, don't miss it. Next, Pat introduced us to the issue of what to do with excess ICBM motors. DOD has kept retired ICBM motors in good condition and Orbital ATK wants DOD to sell them for commercial use,. This is very controversial with most commercial launch companies opposing the idea. Pat explained the issue to us, the role of Congress as congressional approval would be required to sell them. I also asked him what the success rate might be for using these retired engines. That remains an unknown but there is an expected failure rate with them. Burton from Montreal sent in two emails asking about DOD launches requiring bigger rockets than a Delta IV Hea

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed back to the show Dr. Dan Durda to update us on commercial suborbital science research and space adventure (tourism) flights. During the first segment of our 90 minute program, Dr. Durda first talked about the Southwest Research Institute (SwRI) BORE microgravity payload experiment which recently flew aboard Blue Origin's New Shepard space vehicle April 2, 2016. The BORE experiment, otherwise known as the Box of Rocks Experiment, was explained by Dr. Durda plus you can read about it at this SwRI web page: www.swri.org/9what/releases/2016/bore-microgravity-payload.htm#.Vyi3OTf2ZD8. In learning about BORE, I asked how much zero g time the experiment had and what was typical for a commercial suborbital flight. His answer might just surprise you. Dr. Durda then addressed suborbital flight with Virgin Galactic, XCOR, and Blue Origin. Several listeners wanted to know when each company would go operational with their flights. Another listener wanted to know the approximate mix for science and tourism flights. Then later in the segment we talked about other experiments, Saffire-1 and Strata-1. If you Google those two terms, you can find the NASA websites for the two projects. Before the first segment ended, Helen asked if our guest was caught off guard by the advanced Blue Origin condition as exampled by their accomplishing reusability and then flying their rocket over again. Helen said that since Blue was not that public in their announcements lots of people were caught off guard by outstanding Blue achievements. Don't miss what our guest said about this but for the most part, he suggested that since they were working with the company, they had a good idea of just how advanced they were with their flight programs. In the second segment, we talked about the potential of simple life on small asteroid like o objects. When asked what he meant by life, he said "geologic" life. Listen to his explanation. We then talked about exoplanets, finding some that are in their star's habitable zone, then how we study those items plus what we can learn about them. In the context of this discussion, we talked about the use of different kinds of telescopes, including the upcoming JWST. Listener John sent in a note about the recent show with Dr. Seedhouse plus his upcoming book on XCOR. Our guest was very familiar with Dr. Seedhouse and his work. I also asked about the possible revenue mix between space tourism revenue as compared to science revenue. Our guest provided a comprehensive answer to this specific set of questions but based on what is known so far. Thus, about all one can do at this point is speculate. Another topic was the competition among SpaceX, Blue Origin, and Virgin Galactic. Dan had much to say about this competition and importantly, how it might change in the future as the commercial revenue starts to flow. This topic was a result of my asking if he thought all the suborbital companies would survive o

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed back to the show Dr. Paul Spudis for a discussion about his new book, "The Value of the Moon: How to Explore, Live, and Prosper in Space Using the Moon's Resources," plus Dr. Spudis responded to many listener questions about returning to the Moon, going to Mars, and U.S. space policy. In the first segment of our 1 hour 45 minute discussion, Dr. Spudis introduced us to his new book, then I asked him to elaborate on his chapter that provided three reasons for our going back to the Moon. Paul went over the three reasons so let us know with a blog comment what you think of them. I do! I asked our guest why it has been so challenging to return to the Moon. You do not want to miss what Dr. Spudis said in response to my question. Listener emails started coming in with Karen asking why not first solve our economic problems before going into space or returning to the Moon. Dr. Spudis gave her a good answer, showing how important space has become to all of us. Listeners wanted to know the Spudis roadmap for returning to the Moon so our guest summarized it on air but for all of it, get a copy of his book as that is where the details are located. Listener John wanted to know about public private partnerships, could the Moon be developed totally by the private sector, or would it be developed by only the government. Again, don't miss what our guest had to say in response to this question. Another topic in this segment was Mars and going there as our priority. Dr. Spudis had much to say about going to Mars, using the Moon as a learning and testing base and being the only rational way to have human spaceflight to Mars. Mars was a major part of our discussion as it is a popular target for lots of people regarding spaceflight. We talked about SLS & Orion, , using the big rocket and capsule for going to the Moon, not Mars, and the need for a lunar lander. Dr. Spudis also talked about the important role of robots in returning to the Moon. In the second segment, Judith from Seattle asked what Paul thought of one way trips to the Moon, similar to what Mars One was planning for Mars. He did not think much of them but listen to all of what he had to say about a one way lunar mission. Cislunar transportation was discussed in some detail in this segment. So was the possibility of a lunar space elevator and the changing of US space policy to make space settlement a priority. In this context, our guest had much to say about ISRU.. Next up was an email from Luis in Venezuela asking about solar electric power (SEP). SLS John called to be supportive of Paul's comments about SLS being a placeholder for American labor, skills, and technology. Please read the rest of this summary @ www.thespaceshow.com.

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed back Dr. Stuart Robbins for a space science discussion that addressed many topics and interests. During the first segment of our 96 minute program, Dr. Robbins talked about the recent gravitational waves discovery, then he talked about New Horizons and the incoming Pluto data. We talked about Pluto's status as a planet or a dwarf planet. Listeners asked several Pluto related questions. One thing our guest said was the surprise in finding Pluto to be so active. Dr. Robbins talked about the wide differences in age dating for Pluto ranging from 74 billions years for some surface and other features to just 1 billion years old. He said there was no explanation for this as of yet. At one point I asked him if a fleet of astronauts on the surface of Pluto could do faster and better research than robots of today. Don't miss his answer to this question. Dr. Robbins has a specialty in studying craters so he was asked if craters were similar throughout the solar system. This was an interesting discussion which included the subject of Halo Craters so don't miss it. Following craters, our guest was asked about Pluto's mythology. He spoke to Pluto being the God of the Underworld. BJohn asked a question about the chaotic rotation of Pluto moons. Johanthon asked about an idea he had regarding the Higgs-Boson particle. In the second segment, Jennifer emailed in a question about some space projects being a waste of money compared to others. This prompted an interesting discussion with our guest, one you will want to hear. This discussion then led to our talking about the private sector doing science missions, returning to the Moon, or partnering with government on a purely science mission. Again, don't miss what Stuart said in response to these questions. Stuart took a listener question inquiring about weird or near crackpot ideas or theories now circulating and in vogue. Our guest talked about the scientific method and the subject of plate tectonics before it became an accepted theory. He pointed out that even when it was a fringe idea, promotors of it went through the publication and presentation format for scientific analysis and verification. As he said, "they played the game." Stuart said that if one is presenting a fringe or out of the box idea or theory, it still needs to go through the process to be taken seriously - most of the time. Listener Johnathon then called the show to ask Dr. Robbins about his theory he presented during the Feb. 28, 2016 Open Lines Show. Stuart could not comment on the theory but pointed to the type of research Johnathan needed to do to have scientists consider it and he suggested several resources for our caller. This included running numbers, examining actual data from Cassini through the PDS (Planetary Data System) and publishing and presenting in more or less official scientific publications and conferences. Publishing ideas on a website or a blog us

John Batchelor and I welcomed Dr. Jim Green, NASA Planetary Science Director, to discuss NASA partnerships with national space agencies with a focus on the Japanese Space Agency (JAXTA). During our double Hotel Mars segment for about 20 minutes, we discussed the Japanese missions Hayabusa, Hayabusa 2, and Akatsuki which is now in orbit around Venus. Some of our questions dealt with the Hayabusa comet visit and sample return, plus the Hayabusa 2 mission now en route to asteroid 1999 JU3. We talked about the way NASA contributed to these missions, ground simulation models for mission problem solving, sample returns, and the art of planetary mission sample return. We also spoke about Akatsuki which after several years is now in orbit around Venus due to years of problem solving for a propulsion problem. Dr. Green explained this methodology to us plus we talked about some of the very early science discoveries regarding Venus given Akatsuki is now orbiting our sister planet. As the segment was ending, Dr. Green mentioned the next JAXTA mission, MMX Martian Moons. NASA is working with JAXTA on this mission as well. You can email Mr. Batchelor or Dr. Green through me at drspace@thespaceshow.com. You can also reach Dr. Green through.
