We welcomed back Ken Murphy to discuss space current events, his coming articles and stories, and reasons for returning to the Moon and developing cislunar space.  During the first segment of our 2 hour 2 minute discussion, Ken started out by telling us about his upcoming Jan. 4, 2016 Space Review article regarding the July 2016 Moon Day celebration in Dallas.  He provided the logistical details for the event throughout our discussion, plus he described the event, the Lunar Sample Bags, the educational outreach, and their ham radio connection to the ISS via the ARISS Program.  This discussion was followed by our talking about the SpaceX Falcon 9 launch and first stage recovery.  Ken then talked about making significant changes in NASA to advance space development, especially getting younger employees at NASA with an average age in the 30’s by getting rid of the older NASA employees.  This comment caused John from Ft. Worth to call to remind Ken of anti-age discrimination laws, wondering just how Ken would get rid of the older people at NASA.  We shifted our discussion to cislunar development and international lunar development efforts.  We talked about the need for public private programs to do cislunar and lunar development.  Betty emailed Ken to ask him if he thought all the lunar advocacy made a difference and helped the cause of our getting back to the Moon.  Ken’s response to Betty might surprise you so don’t miss it.  Before the break, we talked about education and the public’s space educational level.  You definitely want to hear what Ken said about the average person’s space knowledge and teachers in our K-high school grades.  Tell us what you think about Ken’s education and teacher analysis and comments by posting your thoughts on TSS blog.

In the second segment, we talked about going back to the Moon, then Ken brought up lunar dust issues, then in response to the typical Moon or Mars question, he said the Moon was our sand box made to order to train us for solar system exploration and even settlement.  He also said while he is interested in Mars and space settlement, his near term focus was on cislunar development and returning to the Moon.  During our program, he often referred to talks he has given to the general public so he talked at length about both space and STEM being a hook for getting young people interested in space and the STEM topics.  He again mentioned that on Moon Day, they would be talking with the ISS crew via the ARISS program,.  Preston from Chicago asked him if he had seen The Martian or the latest Star Wars movie.  His response and what he said about the movies will have to be a surprise for you.  Near the end of the program, Jerry asked him about his support for advanced propulsion and Jack asked him what he thought of Elon’s plans to go to Mars in 15 years or so.  Ken was also asked for his opinion on space solar power and about using water ice on the Moon for fuel.  Ken said it would be better to work the Moon from L1.  In conclusion, he offered us a good takeaway message and a good set of closing statements you will want to hear.

Make sure you post your comments/questions on TSS blog.  You can reach Ken through The Space Show or The Moon Society (www.moonsociety.org).  Finally, Merry Christmas everyone.  The Space Show team and I wish you a very good holiday season.

We welcomed both Jay Wittner and Ron Jones to the program to discuss the Integrated Space Plan (ISP), “a real and detailed timeline of our future in space for the next 100 years. Vehicles, Stations, Settlements, Moon, Mars, Asteroids.” You can see the ISP at https://integratedspaceanalytics.com/cms/plan and also their previously successful Kickstarter site, www.kickstarter.com/projects/486671231/integrated-space-plan-envisioning-humanitys-future. Wired Magazine did an excellent article on the plan which you can download and read at www.wired.com/2015/08/wildly-detailed-100-year-plan-getting-humans-mars.. Discovery also did a nice article on the ISP dated Oct. 16, 2015 which you can read and download @ http://news.discovery.com/space/private-spaceflight/isp-the-ultimate-plan-to-launch-humanity-to-the-stars-151016.htm. During the first segment, Ron provided us with the history of the ISP which goes back several decades. He explained its purpose and how it has changed and evolved over time. In fact, later in the show I asked our guests if the time had finally come for the ISP to come into its own given the developments and progress in space development. You will certainly want to hear this discussion which comes much later in the show. The first segment is mostly devoted to describing the ISP and responding to basic listener questions about it as it was new to most listeners. I also urge you to look at it on the web using the above links so you can be come familiar with the plan and its blocks. Remember, it is a broad enabling approach that includes many different paths to accomplish space development, exploration and a spacefaring economy/society. It is not about a specific program or project as we are used to discussing on The Space Show. Specific plans and projects can nicely fit in the appropriate blocks on the ISP as the ISP is a collection of logical and plausible multiple paths to space development without saying this or that specific plan is THE plan we must follow. Toward the end of the first segment, John in Freemont, CA asked about the Shackleton Energy plan as was recently discussed on The Space Show. This was a good example for our guests to show how the ISP could nicely accommodate the Shackleton plan but that the ISP was actually much broader and more inclusive than just the three part Shackleton plan discussed on The Space Show. As you will hear, there is no conflict between the two.

In the second segment, Jay was asked how people could get a poster copy of the ISP. Jay and Ron told listeners how to order a poster copy (the rolled version in a tube is the best way to get it). We also talked about support for the ISP by many from within all segments of the space industry. Later, much was said about outreach for the private sector and also the student population, especially through SEDS. Jay and Ron invited listener participation and feedback and they gave out their respective email addresses or told listeners how to find their addresses on their website, www.thespaceplan.com.   We talked about disruptive technologies and how they were represented on the ISP. GPS was used as an example since I referenced Uber from our Friday Space Show program. As part of our disruptive discussion, our guests talked about SpaceX, the Falcon Heavy, reusability, and more. A listener asked about cislunar development and how that was represented on the ISP. Frequent Space Show guest Gerald Driggers called in with many interesting comments so make sure you listen to his discussion. His call was followed by John from Ft. Worth asking about actual markets & customers for the businesses.  Our guests talked about the key to customers would be lowering the cost to orbit, then they mentioned space tourism and specific payloads. As our program was ending, both guests offered closing comments and take away statements.   Both made a final appeal for listener participation and feedback as the ISP is a continuingly evolving plan.

We welcomed to the show Dr. Jens Biele of the DLR to discuss the Philae Lander as part of the Rosetta Mission to Comet 67P. During the first segment of our 1 hour 27 minute discussion, Dr. Biele summarized the Rosetta mission going back to its planning and development days, the flight to Comet 67PM and the Philae Lander’s anchor landing failure which he talked about at length. He also talked about communications from the lander to the orbiter and the narrow window for successful communications. We talked about solar and battery power, the type of data it can still transmit and related issues. Later, he was asked about other forms of propulsion including ion thrusters and advanced propulsion, plus he was asked if it would have been better to power the spacecraft by an RTG. He summarized some of the trades involved in making these types of decisions so don’t miss the discussion. BJohn asked about other DLR missions so MASCOT was discussed and later he discussed AIDA and AIM. As part of this discussion flyby missions were detailed and trojan asteroids were discussed. The subject of searching for life came up along with the discovery of organic molecules. Near the end of the segment, Roger from Rutgers asked if they considered Philae a success. Don’t miss his answer to this one. Other topics in this segment including drill samples, mission operating cost considerations, launcher choices and the shape of 67P which was a puzzle yet to be explained.

In the second segment, I asked our guest about the extremely long mission planning and design times coupled with the very long flight time and how that impacted people wanting to work space projects. As you will hear, it is not much different in Europe than here in the States with the same issues with NASA missions here. BJohn asked additional questions about future DLR missions and robotic exploration. This is the discussion that talked about both the AIDA and AIM European missions. Listener Helen asked about general European public support of ESA and space. You might be surprised by what our guest had to say in response to Helen so don’t miss it. In this context, Dr. Biele talked about ESA PR and its limitations and constraints. Toward the end of our program, he talked about human spaceflight, referenced Mars and going to Phobos as an initial part of human Mars exploration. When I asked our guest for closing comments, he said “If you dare you win. Take Some risks.” His final comments were ” Landers are cool!”

Please post your comments/questions on TSS blog above. You can reach Dr. Biele through me or his DLR website.

Welcome to our last Open Lines program for June 2015.  During the first segment of our 2 hour 9 minute program, we started off with my customary suggestion of a few topics including the Falcon 9 launch failure and a Space Review article from June 8 of this year by Dr. Sam Dinkin, “How much money would it take to launch enterprise into space? (See www.thespacereviewe.com/article/2766/1).  Our first caller, Dr. Dwayne Day, wanted to talk about Sam’s article and analysis.  We had an interesting discussion on its contents but see what you think after reading the short article.  Dwayne also talked about the coming Pluto flyby by New Horizons.  I then asked Dwayne for his thoughts on the Falcon 9 launch failure.  Dwayne offered us several interesting observations about the launch failure and SpaceX.  Our next caller was Tim from Huntsville and he too wanted to talk about the Falcon 9 launch attempt.  He kept repeating we have to do better than chemical rockets.  Before the break, I read an email that came in from Kelly.  Kelly is not a fan or supporter of SpaceX but as you know, The Space Show is willing to air all sides of an argument so I read Kelly’s email on air as it had much to say that was critical about SpaceX.

 

In the second segment Kelly was our first caller.  I put it to Kelly to support his critical comments about the company.  Kelly then talked about lots of issues about SpaceX processes ranging from parts, manufacturing, cutting corners, safety and more.  Several listeners sent in emails asking Kelly direct questions about what he was saying.  I made it clear that I did not agree with much of what he was saying but you give it some thought and decide the issue for yourself. Keep in mind that it is not unusual for a new rocket to have problems, even to fail to reach orbit.  Sometimes many flights have to take place to discover a problem. As I said, I have every confidence that SpaceX will fix whatever the problem is and resume launches as soon as possible.   Kelly sent in a few additional emails during the balance of the show to support the claims he was making.  Our next caller was Dr. Doug from S. California. Doug wanted to talk about the Falcon 9 launch and the need for multiple launchers which he said were a good thing.   Listner Karen emailed us with a question about the Falcon 9 debris field, then Tim called back, then Michael Listner called to continue talking about New Horizons and Pluto.  During Michael’s call, he got a listener question asking if the money would have been better spent on a Uranus mission.  He also talked about the possible regulatory impact of the Falcon 9 loss including RD180 engines, ULA, Air Force certification, and fallout with Senator McCain on his subcommittee regarding the RD180 engines.   Dwayne called back to talk Pluto, the Decadal Survey and planetary missions, plus he talked about the Applied Physics Lab (APL), the Uranus mission mentioned earlier by a listeners and more.

We welcomed back to the show Greg Meholic to speak about advanced propulsion concepts, rocket reusability, and much more.  During the first segment of our 84 minute program, Mr. Meholic first defined what he meant by the term advanced propulsion.  Given this definition, we moved forward to discuss various concepts, propulsion methods, and propulsion research. During this segment, we talked about several propulsion technologies and Greg said thumbs up or thumbs down to their being advanced propulsion.  When it came to nuclear, Greg classified it as an alternative propulsion method, not an advanced propulsion.  Again, don’t miss his definition.  We talked near and intermediate term advanced propulsion concepts though it does not appear anything is really close at hand.  His timeline for a possible advanced propulsion technology was around 20 years.  He said not only do we need to understand the physics much better,  but the propulsion method much compete with current systems and produce benefits including cost benefits.  As far as choke points on advanced propulsion, he said understanding the fundamental physics involved was a big one.  We then talked about funding which is now mostly from companies and other private investor oriented sources.  I asked lots of questions about funding, especially how does one know when the point is reached to either kill the project or keep it going.  Don’t miss what he said about this.  Listeners also asked many questions.  In replying to one listener, he said it would be hard to beat chemical rockets to LEO but the door opens up BLEO though the Moon can be done with chemical rockets.  When asked about the anti-nuke movement and the impact on the nuclear rocket, he had some interesting observations, especially regarding the views of younger people.  When asked for leading advanced propulsion people and concepts, he mentioned former Space Show guest Dr. James Woodward and his work with Mach’s Principle several times during our show.  Greg was also asked about the work of Dr. Sonny White at JSC for warp drive and M drive.  Greg had much to say about his work including Q thruster and M drive.  John from Ft. Worth called in to talk about M Drive & Mach’s Principle along with gravity and magnetic frequencies.

In the second segment, Ashley sent in an email asking about going to the Moon and Mars for settlement and sustainability, wondering if advanced propulsion was needed for either location.  You might be surprised by Greg’s response to this question so listen carefully.  He did say there would be different requirements for the Moon and Mars.  With Mars, he also spoke about radiation and travel times.  Greg then had some things to say about artificial gravity.  One of his comments was that if we understood more of the physics, an eventual advanced propulsion system might enable an artificial gravity system without spinning or the need for tethers.  Brad in Tucson sent in a note asking about reusable first stage rocket launch systems.  Greg was delighted with the question as he works on such systems in his day job and he had much to say and offer about reusable first stage rockets.  He went through a brief summary of some of his work plus those attempting to design such systems including SpaceX.  I asked about a payload penalty with reusability.  Don’t miss his answer.  Our next caller was Marshall and he took us back to the artificial gravity discussion.  Marshal was asking questions about the amount of time spent in 1g as opposed to various fractional gravity loads.  As the program was ending, Greg received the final question which dealt with comparing the quality of government research to private sector research.  He reminded the listener that there very little to no government research funding for advanced propulsion, that it was almost all private sector funding.  He said the private funding was investor based so it comes with a commercial profit focus.

We welcomed Dr. Guillem Anglada to the show from the UK to speak with us about Gilese 581d, exoplanet detection methods, specifically Doppler spectroscopy, and more.  During our one segment one hour discussion, Dr. Anglada explained to us why Gilese 581d (G 581d) has become a benchmark for the Doppler technique for finding exoplanets.  In explaining this to us, we also defined and talked about the habitable zone and why the Doppler technique works better for nearby stars as lots of light is needed.  We talked about the G system red dwarf or low mass star.  I asked our guest about telescopes and just how big a telescope had to be to see G581d for example.  At this point in the discussion, we began getting a series of email questions from listeners that were technical and superb.  I read them all on air ranging from asking about microlensing to occulters, to questions about our Sun and much more.  I asked Dr. Anglada what Earth would be like were we standing on G 581d and trying to detect Earth.  Do not miss his answer, it might surprise you.  Listeners also asked about the impact of the exoplanet field on students and if it was driving STEM enrollment.  We got two emails from a new country during this show as Michael sent in questions from Slovenia.  In one question, he asked about a free-flying coronagraph that could occult stars for direct imaging, especially for ground based telescopes.  There was more to his question so don’t miss it.  His other question was about detecting Oort cloud objects.  Our emailers asked about the transit method for finding exoplanets and our guest discussed alternative methods as well.  We talked about future exoplanet finding missions similar to Kepler such as TESS and PLATO.  Near the end of the show BJohn in one of his questions asked about the use of radio waves for finding exoplanets. This is a very informative and high level discussion with our guest who we will certainly have back on The Space Show.

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.

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.

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.

John Batchelor and I welcomed Marc Millis (www.tauzero.aero) to discuss the movie “Interstellar,” worm holes, black holes, event horizons, folding space, advanced propulsion, and the realities of faster than light travel. We talked about some of the representations in the movie plus John also brought in some details from the older movie from the late 1990s, “Event Horizon.” Marc explained the theory behind worm holes, the need for massive amounts of negative energy, and the challenge in keeping the worm hole opening open once the starship has entered the worm hole. Also discussed were some of the liberties taken with science in representing science issues in the movie.
