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. Selected by: David Livingston [ stations ], Mon, 30 Nov 2015 16:31:41 UTC

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.

Dr. David Crisp, Monday, 11-23-15 (46.43MB; download) -- Guest: Dr. David Crisp. Topics: NASA Orbiting Carbon Observatory (OCO-2), Earth's CO2 environment and more. Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com. Comments and questions should be relevant to the specific Space Show program.

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. 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.

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 David Love from the U.K. to our program. 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. Selected by: David Livingston [ stations ], Mon, 23 Nov 2015 16:28:22 UTC

This will help me bring better programming to the audience. We welcomed back Dr. Jim Logan, Dr. John Jurist, and Dan Adamo for a 1 hour 45 minute discussion about humans to Mars and a critique of the "NASA's Journey to Marts: Pioneering Next Steps in Space Exploration (Oct. 2015)." Please note that our program completed in one long segment without a break. We started off by asking Dr. Logan to summarize the recent New World Space Conference he attended in Austin, Texas. Jim pointed out that there were lots of young students there and they seemed eager to hear his message and did not consider him a Debbie Downer. Jim is an evidence based guy when it comes to space policy and programs, he is also well grounded in the sciences and engineering so he does not typically hang out in the usual space cadet la la land of make believe. We noted that older, more seasoned space cadets often dismiss those with similar messages based on evidence and fact, but Jim was impressed by the willingness of the younger group to consider evidence and facts. The other guests plus myself had much to say about this particular issue, then we moved on to Dan who wanted to talk about the paper he has uploaded on TSS blog containing his analysis and comments re the NASA Journey to Mars Document. If you have not yet read it, please do so at this time. For Dan and our guests, there were issues about a poorly defined definition for exploration vs. pioneering, confusing the two in the Journey to Mars document, the need for congressional action to change the mandate to pioneering, then asking for the rational for pioneering or Martian settlement. Much was said about there being no business case or rational case at all for humans to be on the surface of Mars. This was an overriding theme for the entire discussion. Our guests kept asking the question, "why are we doing it.? This referred to humans on the surface of Mars for pioneering purposes. Note the definitions Dan used for exploration and pioneering earlier in the show. Note also the differences Dan suggested for exploration. Our guests talked about the challenges that make Martian settlement or pioneering beyond our reach at this time. Dr. Jurist brought up radiation and microgravity issues along with other human factor issues. Dr. Logan supported what John was saying and called for the need to know the gravity prescription. Without knowing it, we cannot possibly be serious about sending humans to mars. Our guests talked about nuclear thermal propulsion and several times they referenced the Aquarius Concept (www.spaceenterpriseinstitute.org/tag/aquarius-concept). Cognitive decline was also discussed as a leading challenge. The matter of the Twin Study on the ISS with astronaut Scott Kelly came up. Read the rest of the summary @ www.thespaceshow.com.

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 Michael Listner, space attorney, to discuss the recently passed Commercial Space Law by Congress. This law included a section on asteroid mining that may be an effort to convey to US citizens space property rights. Property rights are not permitted by the UN treaties and Michael said that the new law was sufficiently vague between conveying a property right as opposed to a use right which is allowed in the treaty. Michael and others believe it conflicts with the treaty but many within the industry and space enthusiasts believe this is important as it sets a baseline to improve upon in terms of property rights for the future. Michael also suggested it might be good for the asteroid mining companies as they can show their investors that there is now a basis in law which might help with getting new investment. I asked Michael if international space players would care about this or if it the provisions were enforceable outside the US. Michael suggested they would care because it granted these "rights" only to US citizens and they would likely object to it. John made several references to pirates and corporate plunder but I did not agree with those descriptions. What do you think? Let us know on the blog. You can email Mr. Batchelor or Bill Harwood through me at drspace@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 Doug Messier back to the program. During the first segment of our nearly two hour show, Doug started off by telling about his current multi-part series running this past week on www.paraboloicarc.com regarding Virgin Galactic and SpaceShipTwo. Given the accident happened slightly more than a year ago, Doug put together a comprehensive series of articles on the accident, the pilots, the NTSB report, Virgin Galactic, Scaled and more. This is a multi-part series you will want to read. The majority of the first segment's discussion was based on the articles with questions from listeners and myself about various aspects of the company, the accident, the people involved, the mission control room, and the NTSB report plus supporting documents which Doug studied for his articles. Listener Alec sent in an email before the show wanting to know if SS2 has been more closely modeled after SS! if the company would have been flying by now. Doug had much to say in response to this question dealing with the expansion to SS2 which was 3 times larger than SS1 and more. When asked about return to flight, Doug suggested the possibility of Feb. 2016 but that was not definite. This was in response to Josh asking for a Virgin time line. Doug also got questions about Virgin and Spaceport America, then he was asked if noticed differences in Virgin's presentation both pre and post the accident. The subject of safety and test flight programs came up for Virgin, XCOR and all the companies. We talked about safety and test flight programs in general with Doug, myself and some listeners, agreeing that the test programs were not extensive enough or sufficiently comprehensive. Don't miss this discussion which included comments about the flight test envelope challenges, the X-15 as a possible model, and comments made by Neil Armstrong at the recent Suborbital Conference held a few years ago in Palo Alto, CA. In the second segment, I started out by asking Doug about the new Commercial Space Law agreed upon by the House and Senate, specifically the part about asteroid mining and quasi-property rights. I pointed out the feedback I was getting about this section being in opposition to the Outer Space Treat and many were not happy with it, nor did we know if it would have any legal standing outside the U.S. Tim called in to support the asteroid mining provisions in the law. John from Ft. Worth called in to talk about the DARPA XS-1 program and Masten Space Sciences. Burton in Canada asked about SLS, then Dr. Lurio called in to talk safety and many other topics. Before the show ended, Tim called back to ask about the XCOR piston pump progress. Please post your comments/questions on TSS blog above. You can reach Doug through www.parabolicarc.com or me.

We welcomed Wayne Eleazer to the show to discuss the history and why of rocket launch failures per the many articles he has written over the years on these subjects for The Space Review. In the first segment of our 1 hour 58 minute discussion, Wayne started us off responding to my question about the most dramatic launch failure he has seen or studied. He talked about a spectacular Titan failure so don't miss his story. Michael Listner called and talked about many topics including Air Force mishap reports. What Wayne had to say about the mishap reports and the Air Force candor regarding launch failures was very interesting and informative. Wayne introduced us to the Oops Factor regarding failures, a concept he used in an earlier Space Review article. This refers to one thing causing the launch failure but the people down the line with oversight responsibility all miss it or "oops!" SpaceX and the Falcon 9 problems came up many times but here Wayne talked about the needed culture in a company to deal with launch failures, learn from them, and work to keep them from happening again. He thought SpaceX was doing all of that. He also talked about Orbital ATK and the Antares and their culture, then I asked him about the SpaceShip2 failure/accident. Near the end of the first segment, Jay asked Wayne if military rockets had similar launch failure problems. Wayne's response about the military rocket motor, its reliability, testing, and costs was most illuminating. As we learned, the military rocket motor stands alone in quality. In the second segment, Wayne was asked if he could spot trends that cause launch failures over and over again. He said no but listen to his complete answer. He called this the "Predictables" and is completing a new Space Review article on this subject. He listed several examples including his use of the Challenger loss as well as Delta and Atlas failures. I asked him if on the military side, there were consequences for military personnel with responsibility and oversight duties, maybe a demotion, court martial, anything. You might be surprised by his answer to this question. We talked more about the Falcon 9 and EELVs in this segment, plus the old Thor and the Atlas. Barry asked Wayne about Russian launch failures. Wayne talked about the Russian culture and problems. Near the end, he said EELV reliability was improving. He made some additional Atlas and Falcon 9 comparisons, then I asked if there was an expected failure rate for these rockets. Wayne suggested if a company survives ten launches, their odds for survival improve greatly. Doug asked about fairing issues. Wayne talked about the ways that a fairing can open up and we talked about the recent Taurus failures due to fairing problems. Read the rest of the review @ www.thespaceshow.com.
