During the first segment of our 1 hour 25 minute discussion, Dr. Rayman said that Dawn was as close to Ceres as it would ever be & that it was in a stable orbit that would last a very long time as they need to avoid having the spacecraft crash into the surface of Ceres. Dawn is approximately 240 miles above Ceres and its orbital velocity to maintain this orbit is around 600 mph. It takes about 30 minutes for a radio signal to travel one way between Ceres and Earth for a one hour round trip time. He discussed this Ceres stable orbit in some detail. We talked about the mission end for Dawn which will likely happen sometime in 2016 as the thruster hydrazine fuel runs out. He described the failure to us and why they cannot predict with certainty the end date an time. Marc also talked about the reaction wheels (gyros), the fact they lost two but had one spare to use. He explained how they have been operating the spacecraft with just two gyros instead of the required three. We talked about some of the new information coming back, exciting findings by Dawn and of course the mysterious bright spots. Marc commented about the mountain Ahuna Mans which rises to about 20,000 feet above the surface. Doug called to ask about the water ice and the dark cracks he saw in the photos of the bright spots. He also inquired about a human mission to Ceres. Listeners brought up private human missions, including the possibility of a private human mission to Mars. Don't miss what Dr. Rayman said about these potential missions. In response to a question about what would humans do on Ceres, our guest said EXPLORE! BJohn wanted to know if Vesta and Ceres had a special alignment making the mission possible or if we could pretty much visit any two asteroids as we did with these two (dwarf planets). Doug emailed in asking how the astronauts would actually get around on the surface of Ceres, a question which led to discussing Ceres gravity. In the second segment, I asked Marc how he and the others associated with these very long term planetary missions develop the patience to wait years and years for the spacecraft to arrive at the destination and start doing what it was designed to do. Marc had some interesting comments and observations about this. Jerry asked if nuclear propulsion would benefit missions such as Dawn and planetary science in general. Helen wanted to know what was the most disappointing thing about Dawn. The reaction wheel failure was a big item but Marc had interesting things to say about defining something related to a mission as a disappointment. Another listener asked if JPL tracked the general population popularity of its planetary missions. Later in the segment we discussed robots vs. humans f

This will help me bring better programming to the audience. We welcomed back Dr. Jim Dewar to the show to discuss his plans for the use of nuclear rockets specifically from Earth to LEO. In addition, Jim's book (it is out of print) "The Nuclear Rocket: Making Our Planet Green, Peaceful And Prosperous" is being made available as a Space Show fundraiser and we thank Jim for this great gift. You can get a new paperback autographed copy of this book for a $50 contribution to The Space Show. Please make your contribution using Pay Pal on TSS or OGLF websites or mail a check to TSS as instructed on the donation page of the websites. Also, send me an email telling me your $50 contribution is for Jim's book, provide your full name and your mailing address. I need this email to know you want the book in exchange for your donation. As of the time I am archiving this show, I have only ten remaining copies of the book to give away so act fast as once they are gone, this offer ends. During the first segment of our two hour show, Dr. Dewar outlined his plan to break the nuclear rocket ban on using a nuclear rocket from Earth to LEO. Jim spent some time explaining the history behind this ban which is not law! The ban came to be in 1960 as a result of a luncheon meeting. Listen to his telling of this story. Do you find all of this frustrating? I asked Jim how nuclear propulsion would work from Earth to LEO. As you will hear, he said it was applicable to second or third stages on the rocket, not the first stage of the rocket. He explains this in detail so don't miss it. Most of the first segment was devoted to discussing this ban, the early nuclear rocket history and tests, questions about the Soviet Union nuclear rocket program, the U.S. Congress, and cost comparisons with chemical rockets figuring in the cost for permits, dealing with protestors, time delays, etc. Jim also explained the economic benefits of his unique public private partnership he wants to see created to do nuclear propulsion to LEO and why. His methodology for making this happen is potentially doable. In the second segment, we continued talking tech about the nuclear rocket including core issues, the possibility of gas cores, specific impulse for the NTR, then a question came in about supporting the NewSpace agenda of NASA supporting space settlement and low cost space access. He was asked if the NTR plan he was proposing supported these NewSpace goals. Don't miss what he had to say about this as I believe it was an important part of the discussion. Jim repeated often during the show that as a nation we were nearly $20 trillion in debt and bankrupt. Read the rest of the review at www.thespaceshow.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 Timothy (Tim) Sandefur, principal attorney at the Pacific Legal Foundation, to discuss his article at Claremont.org, "The Politics of Star Trek." You can download this article at www.claremont.org/crb/article/the-politics-of-star-trek. During the first segment of our 81 minute program, Mr. Sandefur introduced us to the Star Trek universe, explained the focus of his article, his long standing interest in Star Trek, and why he wrote about this subject. He discussed Star Trek in the context of what was happening with liberalism in the country at the time as the New Left was just starting to develop. All the writers were liberal, the Vietnam war was a crucial turning point with liberalism as was the Chicago Democratic Convention with its riots. The New Left, which he described, was challenging the traditional left, a challenge that Star Trek picked up upon in the various series. Our guest was asked if political correctness was part of Star Trek since the original series which aired from 1966-69. As you will hear mentioned several times in our discussion, Star Trek aired during turbulent times in the country and political correctness was at its earliest stage of development. He cited some examples of how the writers were going off in this direction. In addition, he talked at length about the differences represented by Captain Kirk and Mr. Spock, again citing various episodes by name as examples of what he was describing. He backed up his description of tension between Spock and Kirk with episode facts. Later, I asked him if the basic Star Trek themes, especially for the original series, were also themes represented in literature as well as other movies such as The Matrix. Mr. Sandefur talked at length about the Matrix and said Kirk always chose reality no matter how harsh it would turn out to be. Kirk always chose the red pill. Mr. Sandefur talked about the background of Roddenberry and others coming out of WW2, NAZI hunting which was going on even as the show was being produced, all of which helped to solidify their view of humanity which they worked into Star Trek series. Again, our guest cited several episodes by name, describing why that particular show reference supported what Mr. Sandefur was describing. A listener asked him about the Klingons. Our guest explained how the Klingons were cast as unmitigated evil as Rodenberry and the writers equated them to the former Soviet Union in the Cold War. The Klingon discussion was most interesting. We talked about the development of Warf in the later series &the Klingon warrior culture obtaining almost celebrity status. Read the rest of this summary at www.thespaceshow.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. Linda Spilker to the program to discuss the NASA Cassini mission to Saturn, Cassini Saturn discoveries, and more. Note that our program was 66 minutes in length in one segment. We started our discussion with Dr. Spilker doing a quick overview of the Cassini mission. It took seven years to get to Saturn and has been flying around the Saturn system for11 years since July 1, 2004. Cassini will run out of fuel with a spectacular final mission in September 2017 which we discussed later in the show. Dr. Spilker talked about the design and budget compromises made with Cassini, the mission plan or the Cassini "tours," the protests against Cassini due to the NTG aboard the spacecraft, plus the path it took to get to the Saturn system. I asked Dr. Spilker for the highlights so far regarding Cassini discoveries so don't miss what she had to say about this given there have been so many great findings and discoveries. We also talked orbital dynamics for Saturn orbiting the sun (1 orbit=30 Earth years) and Cassini orbiting Saturn or touring the rings or the moons. Highlights included the polar geysers discovered on the moon Enceladus, the mysterious red streaks on a smaller moon, Tethys, plus countless discoveries about Saturn's ring system. Linda had much to say about Titan and the Huygens Probe and its camera limitation due to a question by Dr. Doug. We also talked about finding organics in the Saturn system, the possibility of life, & comparisons to Mars and Europa. Ben asked if the huge gravity field of somewhat nearby Jupiter had an impact on Saturn. Sherry wanted to know if NASA, JPL, or members of the Cassini team ever heard from the NTG protestors with apologies given the great success of Cassini. I bet you can guess what Dr. Spilker said in reply to Ben. Our guest was also asked if a future mission could be done using solar rather than an NTG. While Linda was not certain of it, she did say that great advances have been made in solar panel effectiveness, storage, etc. NASA is looking into the possibility of doing a Cassini like mission using solar power. Karen wanted to know how long it took Cassini to orbit Saturn. The answer required knowing the specific tour Cassini was undertaking at the time but anywhere from 6-7 days to a few months depending on the tour. I asked Linda how JPL planned these tours so don't miss how this is done and how a mission is planned for a spacecraft such as Cassini. Doug emailed in another question about possible ion propulsion usage and Burton in Montreal wanted to know if a Saturn probe mission might be part of the new NASA New Frontier Mission group being planned.

This will help me bring better programming to the audience. Welcome to our Open Lines program. In the first segment of our 1 hour 56 minute discussion, I mentioned the Dark Matter article from The Economist as my friend sent me the actual article. You can download or read it here: www.economist.com/news/science-and-technology/21678126-powerful-gamma-rays-centre-milky-way-look-signs-elusive. John from Fremont called and mentioned the article, then he talked about advanced propulsion, nuclear propulsion, and Vasimir. He wondered if NASA was serious about nuclear propulsion despite a slight increase in the R&D budget for it. He also wanted Dr. Judy Curry to return to the show in light of the Paris Global Warming Conf. going on this week. I brought up our recent show on NASA's OCO-2 satellite with guest Dr. David Crisp. John from Ft. Worth called to talk advanced propulsion and much about Vasimir. He also brought up global warming and unfortunately I let that topic take up way too much time on the show today. We also talked about Dr. Jim Dewar coming back to the show on Sunday, Dec. 6 to talk about nuclear propulsion and his book giveaway which I will announce on the show next week. In the second segment, I described Dr. Dewar's book which will be the subject of the fundraiser for OGLF. Dr. Doug from S. California called in to tell us he was considering a Kickstarter project to build a large inflatable simulated lunar hab, probably in Arizona. Doug described his project, his lunar hab simulation model, his expectations, his cough estimates, plus he wanted Space Show listener feedback on the idea. Post your feedback on the blog or send it directly to his email address which he gave out on air, or better yet, do both as listeners would like to know the feedback given Doug on this project. Don't miss his call and the opportunity to learn about this potential crowdfunding project. Rick then emailed us to remind us that PISCES in Hawaii was a lunar simulation program. Before the show ended, Doug emailed in about advanced propulsion, suggesting we start on programs using existing rockets and of course the Falcon Heavy. I read his note on air, seems to me he is making sense though to really have an efficient and growing space program I believe we need to implement some form of nuclear propulsion, hopefully sooner rather than later. Adrian emailed us about Vasimir, CO2 atmospheric emissions, and the use of solar power to offset high electrical costs in places such as California. John from Freemont had the last word with a shout out for Blue Origin and an article on the www.theverge.com with Charles Miller explaining the differences in what Blue Origin did as compared to SpaceX recovering the first stage of the Falcon 9. Please post your comments/questions on The Space Show Blog.

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 Dr. Charles Lurio to discuss the suborbital space industry and in particular, Blue Origin. Jeff Bezos's Blue Origin is building the New Shepard suborbital spacecraft which recently flew to 100 km, returned to the pad & landed vertically demonstrating reusability for the first time for a launch vehicle returning from space. Dr. Lurio, John and I discussed the flight, its significance and then John wanted to compare this success to the efforts of SpaceX to land the first stage of the Falcon 9 on a barge in the Atlantic. Both Dr. Lurio and I explained the differences and the challenges faced by SpaceX as they were very different than the challenges faced by Blue Origin. John wanted to know if NASA or other national space agencies were working on reusability. Charles said no with specific comments about NASA. We also talked about the animated part of the Blue Origin video which can be seen at www.blueorigin.com. I also asked Charles about the vehicle plan to go to and from space with passengers on an automatic basis without a pilot or crew. You can email Mr. Batchelor or D r. Charles Lurio through me at drspace@thespaceshow.com. You can get more information about Dr. Lurio at www.thelurioreport.com.

This will help me bring better programming to the audience. We welcomed Sarah Scoles to the show. Check out her website, www.sarahscoles.com. During the first segment of our 1 hour 54 minute discussion, I first asked Sarah why and how she transitioned from astronomy work to being a science and fiction writer. She took us through her path which I found to be very interesting. Next, I asked her about her interest and reporting on various segments of the space industry, starting with NewSpace. In asking her this, I referenced a recent Popular Science article she wrote (www.popsci.com/what-happens-when-space-industry-collides-with-tiny-town) and the comment made by Mr. Witt about Interorbital Space Systems "engines that burn up so they can use themselves as fuel." We had an interesting discussion about this plus her visit to Mojave which included visits to Virgin Galactic, Stratolauncher, then down the road to Palmdale to see and learn about the NASA SOFIA project. Sarah shared her interesting experience getting to fly in the SOFIA modified 747. Don't miss her telling us about this experience and being in the modified 747 with the SOFIA telescope plus other changes to the jumbo jet. Sarah also told us about flying in experimental aircraft with test pilots at Mojave. Sounds like great fun to me! Later, I asked our guest for her top 2015 stories. Mojave was a favorite as was the SOFIA reporting and her article re Brian Shiro and Astronauts4Hire. Later, she also mentioned a hard science stories re B-modes. The scientific work on this project later turned out to be wrong so the paper on it had to be withdrawn. We talked about the possibility of some kind of life on Mars now or in the past, the same for the possibility of life perhaps elsewhere in our solar system. Sarah also liked the Dawn Mission which we discussed. Jack emailed her about one way to Mars trips and Mars One. We learned that Sarah would consider going to Mars on a one way trip though she did not have much to say about Mars One. In the second segment, we talked about the potential for at least microbial life elsewhere in the universe. This led us to talking about exoplanets and I mentioned the previous day's interview with Dr. Crisp regarding climate change on Venus and Mars. I told Sarah and the listeners that according to Dr. Crisp, even with an advanced scientific and technical population on those planets, they would have been unable to stop or mitigate the processes that allowed both planets to become what they are today. Sarah spoke about one of her articles in aeon magazine, "Does Earth have a shadow biosphere?" or "Earth's aliens." You can read this article at https://aeon.co/essays/does-earth-have-a-shadow-biosphere. Read the rest of the summary at www.thespaceshow.com.

This will help me bring better programming to the audience. We welcomed Dr. David Crisp to the show to discuss the NASA Orbiting Carbon Observatory-2(OCO-2) satellite. During the first segment of our 94 minute program, Dr. Crisp started out by presenting a short overview of the OCO satellites, the first two of which did not make it to orbit due to fairing failure after their Vandenberg launch. For the third attempt, NASA switched rockets to the Delta 2 and the satellite made it to orbit without a problem. Dr. Crisp then explained how OCO-2 works, how it detects and measures CO2 in the atmosphere from the ground up. He explained the color intensity and why the information is so accurate. I asked him to compare OCO-2 data with climate models. Here, Dr. Crisp stressed the fact that he was not a climate scientist or policy maker. That said, he did compare and contrast OCO-2 data with climate models to the degree reasonable comparisons can be made. We talked about natural sources of CO2 on earth, both land and water (ocean, rivers, and lakes), as compared to manmade sources of CO2. Dr. Crisp explained the emitting and absorption capabilities from the natural CO2 sources, photosynthesis with plants, and the fact that manmade CO2 is only emitted, not absorbed. This CO2 can stay in the atmosphere for a thousand years or so. He talked about the total parts per million of CO2 in the atmosphere, how it has gone down and now is going up over the years and the amount of human created CO2 in the atmosphere and how that has increased over the years. Listeners asked about methane but OCO-2 was not designed to detect methane. He was also asked about water vapor. Dr. Crisp explained that water vapor in the atmosphere was detected and measured by other satellites, particularly weather satellites so it was not part of this genre of satellites. Jack emailed in a question to point out that a pause was going on for the past 19 years or so and the planet was not cooling despite human CO2 increases. Dr. Crisp offered an explanation for the pause so don't miss it. Jane from Seattle brought up the fact that warming and cooling on Earth has been going on since the beginning of time, without human produced C02. She asked how this could be given the conclusions many make regarding the increase in human produced CO2 levels for today causing global warming. Don't miss how Dr. Crisp responded to Jane. Dr. Crisp also talked about solar warming and cooling cycles and said we are currently in a solar cooling cycle. Randy emailed in a question about the draught in California and its relationship to CO2 increases. In the second segment, Becky in Las Vegas sent in a note asking about the climate and atmosphere on Venus and Mars given our guest has studied both planets.

Mr. Love has written a terrific book on the life and work of Johannes Kepler and early astronomy history. The book, Kepler And The Universe: How One Man Revolutionized Astronomy, is available through Amazon. If you purchase it, please use the One Giant Leap/Space Show portal. Instructions are on TSS website and all archived program summaries on the website and our blog. Please note that while Mr. Love was originally going to do the hour format show, he remained for the full 90 minute discussion without a break. We started our discussion by my asking David about why he chose to write a book on Kepler and I wondered if the success of the Kepler Space Telescope (KST) had anything to do with his choice. As you will hear, Kepler was always a hero to him and he was not influenced by the KST. Don't miss what he said about his connection to Kepler. David then began discussing Kepler starting with his early life as a student with plans to become a Lutheran minister. His path was changed for him by the Church and others and he eventually became a math teacher as he studied math and astronomy. You will appreciate learning about the events that changed the course of his life from being a minister to one of the key people that revolutionized astronomy with his classic three laws on planetary motion that are still applicable today. Mr. Love took us through several of the Power Point slides that are uploaded to TSS blog so be sure to open the PPT and refer to the slides mentioned during our discussion. I won't summarize what Mr. Love said about each of the slides but the slides are a key part of our discussion so again, I urge you to follow along with his Power Point. We discussed the problems with planetary motion as was known by the early Greek astronomers through the time of Kepler and what Kepler came up with to change our understanding of planetary motion through his Three Laws of Planetary Motion. Linda in Seattle emailed asking if Kepler was well studied in the work of the ancient Greek astronomers. The simple answer was yes. BJohn asked about his classic work, "The New Astronomy." Here, David had much to say about the work and also about his contemporary, Galileo. Carl asked why the Lutheran church resisted science and the work of Kepler. Don't miss what our guest said about this. We talked about the influence of Copernicus, Galileo Galilei, Tycho Brahe and others on Kepler. Later, BJohn asked about Kepler being an astrologer which was true. David had lots to say about the "mystical" side of Kepler who never distanced himself from astrology. At one point, our guest said this was an embarrassment! Read the balance of this summary at wwww.thespaceshow.com.
