Guest:  Dr. Donald Rapp.  We discussed using indigenous resources to facilitate HSF to Mars, then the great climate change debate based on facts not agendas.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, https://thespaceshow.wordpress.com.  Comments and questions should be relevant to the specific Space Show program.

We welcomed back to the show Dr. Donald Rapp to discuss two important topics.  In the first segment we addressed using indigenous resources to facilitate human spaceflight to Mars and the MOXIE experiment on Mars 2020.  In the second segment, Dr. Rapp examined the climate change debate without out preconceived belief systems by an honest examination of the data.  To start our first segment, Dr. Rapp talked about the massive amounts of propellant needed for a human mission to Mars which then led us to discussing using resources on Mars to make propellant for the return to Earth.  Our guest was asked about going to Mars via the Moon and using lunar ice to make propellant for the Mars mission.  This proved to be quite a mini-discussion as Dr. Rapp was skeptical about the use of lunar resources including water ice as an assist for a manned Mars mission.  Many listeners asked him challenging questions about his position and conclusions do don’t miss this important discussion.  Later in the segment a listener asked Dr. Rapp about the potential benefits of using nuclear power and nuclear propulsion.  This too was a fascinating mini-discussion so don’t miss it, especially the call on the subject from listener Kris.  Dr. Rapp was asked about the MOXIE experiment which we talked about at length, then he was asked about the need for heavy lift rockets to Mars.  Our guest supported heavy lift which he defined as a 100-120 tons to LEO.

 

In the second segment, climate change was our main topic.  Here he talked about extreme agendas by both the climate alarmists and the climate skeptics and said a new group was emerging which he called the “lukewarmists” who actually and honestly evaluated the data without a preconceived belief system.  Dr. Rapp went through the known facts, the history of the subject, the warming periods, the CO2 levels and where on Earth warming mostly took place though there has been no warming from 1998-2015.  We talked about sunspots and climate change and the impact of El Nino and La Nina.  He also talked about global energy usage and the projected increases for the 21st century and beyond.  The increasing use of power and pollution by China and India were important factors in this discussion.  Listeners had many questions for him including many wanting a way to deal with excessive, costly and unscientific regulations that are forced on the people by politicians who don’t know the facts and have an agenda to their behavior.  No solutions were offered.  A teacher wrote in about the challenges she has teaching factual climate change to her students because parents on both sides of the issue come in and complain that the “truth” was not being taught in the class.  Dr. Rapp offered us concluding remarks around the basic idea that everything is complicated including sending humans to Mars and dealing with climate change issues.

We welcomed Sonia Van Meter to the show to discuss Mars One and the Mars 100 as Sonia was selected to be part of the Mars 100. During the first segment of our 100 minute program, Sonia was asked when she first knew she wanted to go to Mars. Though she has always been interested in space and related topics, it was not until she discovered Mars One that she became interested in going to Mars. During the early part of this discussion, Sonia puts forth why she wants to go to Mars & why she thinks it is important to go there. These themes were repeated throughout our discussion. Sonia got many questions about how difficult it might to leave family and friends plus listeners wanted to know if she was a skeptic about the Mars One mission. Sonia explained the importance of looking forward and focusing on the future, not on being skeptical. She was asked how she got her Mars information. She does due diligence on her own as well as receiving some information from Mars One. Sonia said she was in touch with many of the other Mars 100 finalists and they also due their own due diligence and discuss topics among themselves on a frequent basis. Listener questions by emailed were coming in rapidly asking everything from her backup plan if she did not go to Mars to what she would do for healthcare on the Mars One mission. Many listeners asked her about the risks including human spaceflight medical issues, launch risks, and more. She said the mission would need to be vetted by scientists and medical types and if she did not think it was safe, she would pull out of it. Other listeners wanted to know her perception of living conditions and the Martian environment. I asked if spacesuits would be used and if she did any rough camping, backpacking, etc. as a kid that might have helped her prepare her for tough living conditions on Mars. The MIT Study came up and was discussed as well as growth for the Mars One settlement coming either from Earth, the settlers, or both. She said there would be no childbirth for years as it was not safe so for the time being, the settlement would be growing by subsequent Mars One missions. Doug called to make the case for going to the Moon first. Sonia explained to him that she had no opportunities for going to the Moon though she would take them if offered. The only opportunity she had was Mars One. Sonia was looking at the picture from the vantage point of her own objectives while Doug had the big picture of lunar return and development in mind.

In the second segment, Bill from Virginia asked if Bas or other Mars One executives were planning to go on the mission to Mars. Don’t miss her answer. Todd wanted to know about a possible rescue mission and Andrew sent in a note about Mars One simulations & developing the infrastructure to live off world. I asked our guest if she had factored in launch risks & Randy in Boston asked if she had done a cost benefit analysis on the value of the mission versus the costs of it. Sonia said the educational outreach PR was a large part of the value for her. Privacy issues came up plus she was asked if Mars One went to a moon of Mars would she be disappointed. Don’t miss her answer to this question. Near the end of the show, I asked Sonia for her thoughts should American government regulations make her Mars One trip impossible. I also asked if she had considered or would consider pre-emptive surgery to have her appendix or gall bladder removed before going to Mars. Kris in Denver wanted to know if Mars one went under and the people on Mars were stranded, was it the responsibility of nations and their public sectors to attempt a rescue mission for the stranded “Martians.” Sonia was asked if she would be OK with nuclear propulsion if it shortened her transit time to Mars and then at the end, I asked her about planetary protection and the limits on landing humans on Mars. I directed her to the NASA Office of Planetary Protection for more information.

We welcomed Dr. Pamela “Rai” Menges to the show. I suggest you visit her websites and follow along as applicable with our discussion. Visit http://arsispace.com/spacetechnology.htm and http://starsailorenergy.com. During the first segment of our 1 hour 47 minute show, Dr. Menges introduced us to Aerospace Research Systems, Inc. (ARSI) and talked about the company history dating back to its founding in 1993. We talked about research technologies, private R&D, government funding for research, and specific projects referenced by our guest including the Space Power Laboratory. At one point Dr. Menges discussed the pros and cons of taking government research money and why she elected not to do so. Also, the use of public relations (PR) and the role it plays with those accepting government money. After a brief mention and discussion of the possible space policy positions presented by Ohio Senator Rob Portman, we turned our attention toward power storage and the work our guest has been doing in this area for non-electrolytic power storage. Don’t miss this discussion. Another topic was the use of AC and DC power transmission, the Carrington Event in the 1800’s, and our electrical grid. Jack emailed about the spaceplane shown on the ARSI website, the Ramstar Model. Our guest had much to say about this experimental spaceplane concept and design. I

n the second segment, Ben in Boston asked about telemedicine commercial astronaut healthcare per the descriptive on the ARSI website. Pamela went into detail about this topic, their work with JSC and more. We then spoke to the issue of commercial astronaut safety in general with our guest expressing her thoughts of the safety issues within the industry and the regulatory environment. Later in the segment, the concept of ground effect vehicles came up along with advanced hypersonic technology and even SSTO possibilities. I asked our guest about nuclear propulsion and then several listeners asked her about it as well. Carol’s email took us on a different path as she asked about the need for lots of centrifuges for a peaceful nuclear energy program. This opened the door for our guest to speak about nuclear weapons, the current talks with Iran, and the treaty organizations that safeguard against proliferation. Pamela had much to say about this subject, our government, the Iranians, enrichment, centrifuges, trust but verify and more. Do not miss this discussion. Ft. Worth John called to ask about the use of centrifuges as opposed to other technologies such as gaseous diffusion. Near the end of the program, Luis emailed us about Reaction Engines and the Skylon project space plane. He too sent in a question about winged ground effect vehicles. Kristopher emailed us to check out “Caspian sea monster” on YouTube for an example of these vehicles. Dr. Menges talked about her new book that will be out in the near future and for Pearls of Wisdom suggested “doing what you want to do to pursue your dreams.”

We welcomed Henry Vanderbilt back to the program to tell us about the upcoming Space Access Society Conference to be held in Phoenix, Arizona from April 30-May 2, 2015. For information, speakers, and program agenda, see www.space-access.org. During the first segment of our 91 minute program, Henry talked about the logistics of the conference to be held at the Radisson Hotel North in Phoenix. You can register for the conference and the hotel online. Henry then highlighted many of the sessions and speakers for this year’s event. See the Space Access website, www.space-access.org. I asked him what talk or event excited him the most and he said they all excited him. He then focused on a few main speakers including Dave Masten, Jeff Greason and the COTS 2 Return to the Moon track that Dr. Doug Plata will be chairing. Details for this special track within the overall Space Access track are on the Space Access Society website. Henry highlighted the special track with Doug and his track participants, then he focused on the Town Hall Program designed to solicit new and fresh ideas for cheap access to space and space development. Before the segment ended, Charles Pooley called and we talked about New Horizons and fast, high energy deep space issues and advanced propulsion as a result of Marshal’s phone call.

In the second segment, Doug called to talk about his track but also about the superb networking opportunities at Space Access. Doug, picking up on a first segment listener email question, said that the conference was not a space settlement conference but that with affordable space access, space settlement gets much closer to reality. Henry then spoke about Henry Spencer returning to talk and along with Doug, mentioned reusability and lunar landers. Henry will talk about rocket safety, reusability and more. Advanced propulsion technology was discussed when Ft. Worth John called us, then Henry talked about EML2, more conference speakers plus the need for fuel depots. At the end, he said that the Space Access Conference supports their political activism which Henry is really good at doing during the year on very important and key issues. He cited an example from last year. Henry also said there was still room for more speakers but you need to quickly contact him to see if your topic can work for the event. You can email Henry at space.access@space-access.org.

We welcomed Dr. James Dewar and Dr. John Jurist back to the show to discuss nuclear propulsion and rocket. During the first segment of our 1 hour 40 minute discussion, Both Dr. Dewar and Dr. Jurist talked about the nuclear rocket technology, fuel, cores, past experiences, and how best to modernize the nuclear rocket and move forward with new development. Most of the callers talked technology so this first segment is very technology heavy. Space attorney Michael Listner sent in emails suggesting it would never happen due to the regulatory side of things plus he provided us with the UN Committee on the Peaceful Uses of Outer Space policy on using nuclear power in space (www.unoosa.org/oosa/SpaceLaw/nps.html). Listener Kristopher spoke to our guests about core options and fuels. Check out this site that he sent us: http://www.projectrho.com/public_html/rocket/enginelist.php#ntrvapor. Toward the end of the first segment, I said that after the break the second segment would focus on what to do to make the nuclear rocket policy and to start the program and develop this form of advanced propulsion. Both Dr. Dewar and Dr. Jurist agreed.

In the second segment, we did focus on the need for leadership and organizational structure for developing the nuclear rocket and starting with nuclear propulsion. We had several callers and emails addressing how to sell a nuclear rocket program. Dr. Dewar talked about the economic benefits, jobs, opening up more of space to economic growth and access. I asked about chokepoints and both our guests suggested the biggest chokepoint was the absence of young, passionate, and competent leadership. Related issues that came included how best to get the support of congress as well as the American people, plus why a nuclear rocket was important and should be developed.

We welcomed Les Johnson back to the show to discuss his latest books on popular science & science fiction, solar sails, and much more. In the first segment of our 1 hour 45 minute show, Les began talking about solar sails and their use to go to go around our solar system and eventually to the stars.  There was much interest in the solar sail subject so Les gave us a terrific somewhat technical lesson on solar sails.  We fielded many listener questions and we all learned much about solar sails, their potential, today’s capabilities, materials used, and more.  This was  an exceptional discussion so don’t miss it as solar sails are a very exciting technology for robotic spacecraft.

In the second segment, Les mentioned the Lunar Flashlight and Scout missions.  I asked our guest about the track record for solar sail missions.  If the mission launch was a success, the solar sail mission has been pretty good but there have been issues with the launches on some of the past solar sail missions.  I also inquired about solar sail work, research, and interest around the world and with other space agencies.  A listener emailed wondering if the use of a solar sail made a satellite or a mission more vulnerable to an ASAT type weapon.  We switched gears to talk about the science fiction work Les has done with Ben Bova  regarding mars with his book “Rescue Mode.”  Les talked about his parameters when writing science fiction plus I asked him about the feedback he gets as an author from both his popular science books as compared to his sci-fi books.  You might be surprised by his answer.  Nuclear propulsion came up for discussion and a few listeners wanted to know the human spaceflight awareness level of people when he gives lectures on the topic.  Interstellar flight was discussed as was the movie “Interstellar.”  As we were moving toward closing the program, Less said he believes HSF is going through a golden age and he explained why.

Welcome to our first ever Space Show New Years Resolution and Wish List program.  During both segments of our 1 hour 48 minute discussion, listeners phoned in and emailed their wish list for space development projects for 2015 and even beyond.  During the first segment, Michael Listner started us off with a wish to see a space policy thinker type of website started to open and support a high level discussion on what our space policy should be.  He did not know how to implement the idea but we talked about some possibilities and he suggested a few participants.  Ideas are welcome.  We next heard from Jon in New Jersey who wanted to see Dream Chaser continue on to success along with commercial crew.  We talked about returning to the Moon and using the Moon as a stepping stone to Mars, plus various paths on the way to Mars.  Chris from Wyoming called in and suggested peace between all sides on the SLS debate.  We also talked about lowering launch and access to LEO costs and baby step methodology for getting to Mars.  He also wanted to see strong support and growth for the private sector.   John in Florida called with a wish list item of stopping throwing away the boosters.  He said his extended wish was for ULA, Orbital and others to begin working on reusability.

In the second segment, Andrew from Tucson called.  We talked about Kitt Peake and his projects with Jeff that he has been working on that he wants to continue,  including hardware demonstrationd.  Doug called from S. California and wants to publish his Cis Lunar One paper & move forward on his conference or TED talk concept.  He mentioned the need to spend less time posting on blogs and making more direct contact with leading space policy people.  Tim called wanting to see full Falcon 9 reusability among other things.  John from Ft. Worth called and said his wish list was for more SLS funding and to see a successful Falcon 9 first stage recovery landing on the barge.  Rick sent in emails about fusion energy and more, all of which I read on air.

Please post your comments/suggestions, and your own resolutions and your wish list on TSS blog above.  If you want to contact any of today’s participants, you can do so through me.

Welcome to our first Open Lines show for 2015.  During the first segment of our two hour program, I made a few topic suggestions as usual.  In my suggestions, I asked for listener ideas for both debate and webinar topics plus guests to invite for the suggested programming.  In the second segment listeners sent in many good suggestions but for those of you listening on archives, please send in more.  Sending in guest suggestions for the debate and webinar topics would be very helpful.  The first call was from John in Florida.  He wanted to talk about several topics including the SpaceX effort to land the first stage on the barge.  He also talked about Blue Atlas, Orion, Apollo, the NASA risk averseness and more.  Dr. Lurio called next to tell us where we could see photos of the barge after the crash landing of the first stage.  He also commented on news relating to Blue Origin & the Elon Musk interview on Bloomberg.com.

In the second segment, John called from Ft. Worth, commented on my comments re the email I read about the movie “The Principle” and his thoughts on doing a show with the people behind the movie.  John also asked about the SpaceX refurbishment plans for the first stage once they recover it.  Furthermore, he talked about Elon’s plan for satellites and more.  He asked if SpaceX might be overextending with all the ventures and projects it and Elon are involved in or announcing.  Several listeners sent in debate and webinar topic suggestions including nuclear propulsion, Is Mars The Goal, Mars vs. Europa, National Competition versus International Cooperation, Space Shuttle debates and more.  Pooley called in and we talked about Microlaunchers and other issues.

Please post your comments/questions on The Space Show blog above.  You can reach any of the participants through me at drspace@thespaceshow.com

We welcomed back Marc Millis to discuss the needed advanced physics for interstellar spaceflight plus his take on the new hit movie, “Interstellar.”  During our 90 minute program without a break, Marc debriefed us on his take on the science behind and involved with the new movie, “Interstellar.”  He said there were things about the science and the movie that he liked and that they did a good job with and other things that got a less than positive grade.  For example, he said the way the movie depicted the worm hole was nicely done & he explained why.  One area he did not like was the shuttle like craft being blasted to space on a Saturn V like vehicle but then going back and forth to the other planets.  He said this raised serious fuel issues & questions.  He also said the time dilation effects were confusing and inconsistent.  We talked about black holes, then Marc mentioned the Incessant Obsolescence Postulate which suggests that should a probe or occupied spaceship be launched to the stars, eventually a more modern one will pass it in the future enabling it to reach the destination a lot sooner than the initial ship.  Marc returned to discussing worm holes and the negative energy needed for them to be useful tools for interstellar spaceflight.  A listener from Boston asked about nuclear propulsion and if that was the advanced propulsion needed for interstellar flight.  Marc talked about both fission and fusion propulsion & their respective applicability & usefulness for interstellar flight.  SLS John called for an advanced physics discussion which included the inertial frame of reference and gravity discussion, Mach’s principle, the Equivalence principle, the Higgs particle and more.  This is a great discussion, don’t miss it.  Another listener asked Marc what the minimum advanced physics and propulsion would be to get started with an interstellar flight, then evolving to more advanced tools over time.  Marc outlined a plan he talked about earlier for doing small steps at a time as opposed to a giant leap needing far more advanced technology than what is available now or will be in the near future.  Another listener asked a similar question focusing on the minimum amount of knowledge needed to get started with interstellar spaceflight.  Pooley called in to talk about the Equivalence Principle.  Marc talked about the Tau Zero Foundation and its needs, and then Beth asked why we don’t focus on Mars or the clouds on Venus, both of which are more doable than interstellar flight.  Marc said we need to focus on both at the same time so don’t miss his excellent answer.

We welcomed Bob Zimmerman back to the program for a wide ranging discussion of space news, space companies, projects, programs and more.  During the first segment of our two hour seven minute show, Bob started off promoting his book on Apollo 8, “Genesis” as we are coming up on the anniversary of this famous flight orbiting the Moon on Christmas eve at a distant time in our past.  After Bob’s infomercial was complete, he did have much to say about the everlasting importance of the Apollo 8 mission.  I asked Bob for end of the year space events to keep our eyes on so we talked about the upcoming SpaceX Falcon 9 launch and the attempt to recover the first stage on a barge as part of the SpaceX reusability plan.  We also talked about the Russian Angara rocket test flight.  A listener asked Bob for updates on the NTSB accident investigation for Virgin Galactic.  Bob also talked about SLS (it was yet another recurrent theme throughout the program) and as predicted, he had nothing good to say about it or Orion.  BJohn emailed us to ask about nuclear propulsion.  Both Bob and I responded and while we support it, there does not seem to be a business case for it or demand for it so there is no significant push to make it happen.  Marshall called to talk about the impact of falling oil prices on the space economy.  I had much to say about this as did Bob who in the end talked about trusting capitalism, freedom, and private enterprise to do the right thing.  We also talked about the impact of falling oil prices on the Russian economy, specifically their space program.  I then brought up the interest rate risk which is a huge potential danger for the US economy.  Luis emailed in about Falcon 9 prices of $5-7 million per a January 2014 Parabolic Arc article.  Note that this was clarified early in the next segment.

In segment two, Dr. Charles Lurio called to explain more about the SpaceX launch cost referenced by Luis in the previous segment.  Charles also talked about the Orbital effort to replace the Antares  rocket motor with another Russian motor, the RD 181.  Joe emailed in a note about the compact fusion plans for Lockheed.  Bob used the opportunity to criticize the large companies, their projects, pork, you name it.  Doug emailed in about some Boeing YouTube videos which Bob completely dismissed as having zero relevancy on anything.  Bob also took some slams at Orion and the recent test flight.  Next, we talked about the new announcement about Curiosity finding methane on Mars.  Bob added more to the story and said it was a wait and see situation but ultimately we would have to there to really answer questions about it.  SLS John called and said the program of record was going forward and made the point that for private enterprise to do something in space as Bob kept talking about, there needed to be a profit motive and he doubted that existed other than for some orbital and comsat missions.  Bob disagreed leaving the door open for a private company to pursue something not previously considered, again saying he trusted in the ingenuity of the private sector.  John reported that he had modeled the Falcon Heavy and could show it would take 53 metric tons to LEO.   Bob then talked about Falcon Heavy being cheaper than SLS (planned that is) so there really was no need for SLS.  Henry emailed a question about a possible Europa mission & Bob suggested if they would kill SLS, money could be directed to the planetary science department for things like a Europa mission plus they could still reduce the NASA budget.  In his concluding comments, Bob said he was skeptical about the suborbital industry and that its time had come and gone given the emerging orbital capsules and flight plans.  He concluded saying he was looking forward to the upcoming SpaceX launch abort tests.
