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.  Many times during the show Linda referenced building on the shoulders of the Voyager spacecraft and its Saturn system information.  Todd talked about the end of Cassini which prompted Linda to describe the final mission plan for this terrific spacecraft. You can read about this final mission at http://news.discovery.com/space/cassini-grand-finale-nasas-saturn-missions-daring-end-140707.htm.  John in Philadelphia was the last to ask a question as he wanted to know the size and shape of Cassini, what it looked like.  Linda did a great job explaining the size and shape, and schematic for Cassini.

We welcomed back to the show Dr. Doug Haynes for updates with his Haynes Saucer, Blue Ridge Nebula Starline, Blue Nebula company and his work to fly to Mars offering airline like service.  During the first segment of our 1 hour 16 minute program, Doug went over the history of his aviation and space business development.  He talked about Phase 1 in the 70s, Phase 2 in the 90s, and Phase 3 which is his current phase.  He said his Haynes Saucer was certified by the FAA and the number was 7111NH.  He also talked about his previous work with DARPA and composites.  In response to a listener email, he said he currently had an experimental certification but would transfer to a regular certification soon.  Jack asked him about visiting his facilities. Doug suggested attending his Open House programs which he holds a few times a year. He also talked about the potential of private visits to his Colorado facilities.  I asked him about the size of his operations and how many people he employed.  Doug listed the positions and team spots & said he was still growing.  Terry asked him about his saucer propulsion. Doug said it had three different aspects to it but in general it was ion propulsion with constant 1 g acceleration using gravitics. He said his hover craft used tip drive.  Later, I asked how he generated electricity for his saucer.  Don’t miss his response to this question.  Shelly asked him about human medical factors such as microgravity, radiation, etc.  He said he does not worry much about them due to his very fast transit times with his advanced gravitic propulsion.  Again, don’t miss his full response to this question.  As for vehicle size, it is roughly 9 passengers or less with a crew size of 2, all in his ejection pod which you can see in the pictures on the website as a huge glass like bubble on the top of the saucer.

 

In the second segment, he was asked about his pilots having space flight experience.  He said this was not necessary given they are running an airline plus his very fast propulsion.  Don’t miss all of what he had to say on this.  Clark in Chicago emailed in about the need for heavy lift re payloads & useful payloads to Mars.  He said he was running an airline so he goes orbit to orbit but again, don’t miss all of what he had to say n this topic.  He did explain how passengers would get to the Martian surface, then he was asked if he was cooperating or at least talking to other space companies for participation.  He mentioned Mars One several times as a possibility.  The next subject was ticket prices.  He explained that he was pricing his tickets using the same format as airlines, revenue per passenger mile.  He was going to charge $5 per revenue mile.  I pointed out what it would cost to do a one way 60 million mile flight (not including trajectory distance for reasons you will understand when hearing this conversation), then later he said he would be charging a flat fee of $2 million for the trip.  Spaceports were the next topic as he has been working on establishing the Colorado Space Port at the Front Range Airport near Denver International.  Doug talked about horizontal takeoff and landing only, his escape pod, his takeoff, igniting his engines about 45,000 feet to go to space.  Wayne asked about the Dept. of Defense interest in his project and he said he had been in touch with DOD officials and those channels were open.  Near the end of the show, I asked Doug to explain his E-drive AAMPP which he did.

 

Please post your comments/questions on TSS blog above.  You can reach Doug or subscribe to his email newsletter by using the email address on his websites in the right hand corner.  He uses the “dehas” email.  If you want to subscribe to his newsletter, which I strongly recommend for its entertainment and interest qualities, tell him you heard him on TSS.

John Batchelor and I welcomed back Bill Harwood of CBS Space News to discuss the recent successful SpaceX Falcon 9 double satellite launch of two Boeing satellites that will use ion propulsion to get to their designated orbit over several months. Given the all electric propulsion for these satellites, the payload mass was significantly reduced so both satellites could be launched together resulting in dramatically reducing launch costs. In addition, we discussed the latest glitch with Mars Curiosity that may be a short somewhere in the system which showed up this past Saturday when the Curiosity drill was being used.

We welcomed Dr. Marc Rayman to the program to discuss the Dawn Mission to both Vesta & Ceres.  To find out more about Dawn, visit http://dawn.jpl.nasa.gov.  Also check out Dr. Rayman’s blog The Dawn Journal @ http://dawn.jpl.nasa.gov/mission/journal.asp.   Visit the DS1 site & archives by Dr. Rayman @ http://nmp.jpl.nasa.gov/ds1.   During the first segment of our 91 minute program, Dr. Rayman introduced us to the Dawn mission which first went to Vesta & is now closing in on its second destination, Ceres. We talked about the mission being specifically chosen to visit both Vesta & Ceres & that Vesta data is still undergoing analysis.  Dr. Rayman described Vesta’s Rheasilvia Crater 300 miles in diameter formed by an impact about one billion years ago.  We also talked about Vesta meteorites on Earth.  Dwayne called regarding competing theories about Ceres, planets having changed positions at one time, & Dawn mission limitations.  Perry wanted to know what information the team most wanted to get from Ceres. Dr. Rayman said they wanted to know basics such as what it looks like, what it was made of, ice, etc.  Other listeners wanted to know about Ceres compared to Mars access.  Here, Dr. Rayman had much to say as the subject came up again in the second segment.  Doug wanted to know about the large bright spot on Ceres plus other questions.

 

In the second segment, Dr. Rayman told us about his Dawn Journal (blog) per the above URL.  I asked our guest if he thought of Dawn & other science missions as competitive with human spaceflight missions.  Don’t miss his reply as I believe it was very special. BJohn sent several emails asking for Dr. Rayman’s favorite targets, especially for future missions. He also asked about using nuclear power rather than solar.  Our guest described the solar arrays & why solar was chosen for Dawn.  Ion propulsion came up & was a major discussion topic for the balance of our program.  Dr. Rayman described how ion propulsion worked, why it used a slow but steady acceleration, & its advantages over chemical propulsion.  Matt asked about RTG development for future missions .  Doug sent us another question based on the low Ceres gravity & landing on Ceres to pre-position supplies in advance of a crew.  Our guest pointed out it was far more complicated than Doug implied given that the Ceres orbit was tipped more than 10 degrees from the ecliptic.  Make sure you hear this explanation.  Among the many questions Matt asked, he wanted to know about the German component of the Dawn mission.  As we approached the end of our show, Dr. Rayman gave us a preview of what to expect as we get very close to Ceres, gradually getting as low as Earth & ISS.

We welcomed best selling author Andy Weir to the program to discuss his book “The Martian.”  For more information, visit his websites, http://www.andyweirauthor.com and http://www.galactanet.com.   During the first segment of our 100 minute show, Andy started out by telling us how he came up with the story idea, & his three years spent in writing the book.  I asked if he used consultants, NASA, or other aerospace experts.  He said no & that most of the feedback and help came through suggestions from people who read the chapters he put up on his website.  Andy also did his own research, math work, physics, and engineering analysis.  He talked about a few errors that were pointed out to him & indicated that the most challenging work were the times and orbits regarding Mars and the missions described in the book. During the show, Andy got lots of email questions and phone calls regarding certain story lines and sections of the book.  He was also asked about life on Mars but that issue was not relevant to his story.  He did get questions about the human waste recycling carried out on Mars & why he chose Mars and not the Moon or another destination.  Sandra asked him about the private space company plans to visit and/or settle Mars given how hard it was for Andy’s character, Watney, to survive.  Andy had very interesting comments on this question including the Elon Musk Mars plans and then Mars One.  Human factors were brought up including radiation, microgravity, vision problems, and more.  Andy did address these issues in the book so listen to his reply to this line of questioning.  As the segment ended, we talked about using Phobos and Deneb for Martian navigation along with Watney’s trek to get to Pathfinder to use its parts for communication.  NASA came up several times in the segment as readers get a pretty good “view” of NASA problem solving, information, data, and PR control, plus amazing creativity.

In the second segment, we had lots of listener emails and phone calls.  Andy was asked what science fiction had influenced him, then he got an interesting email from Andrew in Tucson who had actually worked on the Pathfinder hardware.  Andrew said Andy was spot on accurate!  Dr. Doug called on many topics including using the Hohmann Transfer Orbit which Andy did not use as he designed Hermes, the big spaceship, to work with constant acceleration using ion propulsion.  The Aldrin Cycler was also mentioned.  Listeners mentioned the new movie Interstellar and made some comparisons if they had read “The Martian” and seen the move.  In both segments, we talked about “The Martian” being made into a film for release in a year.  Andy said so far the scriptfollowed the book but he did say he has no editorial input to the movie.  We got a call from Curt in Taiwan who wished there was a PG version of the book given he wants his kids to read it and some of the language is course.  Sara emailed us from Denver asking if Andy had considered making the hero character Watney a woman instead of a man.  Tim was the last caller & he wanted to know if the hard science & engineering would be in the movie.  During this final segment, Andy was asked about how he got to Mars without a transfer orbit.  He suggested we view his animated video on this at http://www.galactanet.com/martian/hermes.mp4.  In addition, he referred us to his Google talk.  You can easily find it by searching for “Andy Weir Google Talk.”

Please post your comments/questions on TSS blog above.  You can reach Andy through his websites or me.

We welcomed back to the show Dr. Jason Cassibry from the University of Alabama Huntsville to discuss nuclear propulsion of all kinds.  In our initial segment of this 1 hour 30 minute discussion, I first asked Dr. Cassibry about a fusion drive project as reported at www.youtube.com/watch?v=r-jlv1x3ov4.  Dr. Cassibry spoke about the work going on at the University of Washington which was mentioned in the fusion drive video above.  We then talked about transit times to and from Mars and the differences with chemical propulsion, nuclear thermal, and then fusion.  During this discussion, Jason also described the differences in nuclear thermal and nuclear electric propulsion.  A related issue we discussed dealt with the nuclear regulatory environment.  We talked about the nuclear climate, protests, and how best to overcome such protests.  Doug called asking about timelines and said it was moving at such a slow pace, for his projects that he thinks about, he dismisses nuclear propulsion, instead opting for analysis and mission planning using chemical rockets though many are not much further along than a Power Point at this point in time.  Doug also thought it might be easier to do nuclear propulsion by partnering with Russia as they might be easier on the regulatory environment than the U.S.  Our caller asked about ion propulsion and thrusters as well as thermal protection needs.

In the second segment, Jerry emailed about nuclear propulsion in other countries plus more about possible consumer protests.  Ben asked if we could substantially improve chemical rockets and I inquired as to why the recent nuclear program Prometheus was killed.  VASIMIR was next brought up for discussion.  I asked Jason about nuclear accidents in space or on Mars and would they be as destructive as nuclear reactor accidents here on Earth.  Jason provided a most interesting answer saying he thought nuclear reactors in space would be accident proof!  Christine in Dallas suggested we need a better story for more support for nuclear propulsion.  Don’t miss the reply offered by Dr. Cassibry. Near the end of our discussion, I asked our guest about suborbital propulsion.

Welcome to this 2 hour 14 minute set of three interviews recorded at AIAA Space 2013 in San Diego (except for the last interview).  Please note there were audio issues as there was background noise both at the San Diego Convention Center and the restaurant where I met Michelle Evans for her interview regarding her X-15 book.  The NASA Press Conference, while conducted in a private room, also consisted of a conference call through NASA with media reps not at the conference.  Some of the participants at the table and on the phone spoke with a very low voice.  The interviews follow one another with about five seconds of dead air space between each one.  When the interview with Michelle Evans ends, so does our recording.

We started with Dr. Doug Plata who presented two papers at an AIAA Technical Committee Meeting Monday night.  His two presentations covered space advocacy unification ideas and his Lunar Cots and Cislunar transportation ideas.  Doug reports interesting and sometimes challenging feedback from those listening to his presentations.  And it was not all supportive of his idea.

Next, we have the NASA Press Conference.  As part of the background to this press conference, the keynote at lunch was a panel moderated by NASA’s William (Bill) Gerstenmaier with four other NASA participants charged with leading different parts of the NASA Asteroid Redirect Mission.  At lunch, these individuals made a presentation, showed animation and video of the mission, charts and graphs, then took questions from the AIAA lunch audience.  The NASA participants got tough questions about SLS, mission dependency on SLS, the use of large quantities of Xenon, and even if the civil space program for human spaceflight would disappear if this mission failed for any reason given the dysfunction many see in NASA at this time.  I think you will find Bill’s response to my question about SLS issues and dependence on it for the mission to be interesting. I learned a few things about SLS and I suspect you will also learn a few things about this program.  Let us know your thoughts on both SLS and the asteroid redirect mission by posting on The Space Show blog.

The last interview was at a Fuddruckers Restaurant off I-5 as I was driving through Orange County on the way back to Hollywood.  I met Michelle Evans and Cherie for a different type of discussion about Michelle’s excellent book, “The X-15 Rocket Plane: Flying the First Wings into Space.”  Michelle was recently a guest on the program about her book.  We talked about those she interviewed for the book and their thoughts on today’s current space program.  I also asked if Michelle thought a program such as X-15 could be initiated today.  Michelle also told us about the global interest in the X-15 as she has heard from people in Nepal, Austria, and many other faraway places.

Please post your comments/questions on The Space Show blog.  If you purchase Michelle’s X-15 book, please do so though The Space Show/OGLF Amazon portal.  You will find instructions on all archive summaries and the blog.

Open Lines, Tuesday, 9-4-12

http://archived.thespaceshow.com/shows/1848-BWB-2012-09-04.mp3

Guest:  Open Lines with Dr. David Livingston.  Topics:  Life outside the solar system, Philadelphia light pollution, ion propulsion, U.S. economy, NASA, space program funding.  You are invited to comment, ask questions, & discuss the Space Show program/guest(s) on the Space Show blog, https://thespaceshow.wordpress.com.

In our second segment, John from Atlanta called in to discuss ion propulsion & fuel plus he wanted to address the economic issues I raised in the introduction to tonight’s program.  Regarding the economic issues, John suggested we were still not so bad where the economy would start to impact NASA funding but if thing worsen, it is likely that NASA & all space funding will be impacted.  John & I went back & forth for several minutes discussing the economic situation, the national debt, space & more, both from the U.S. domestic perspective as well as the global perspective. We talked about the total budget going to NASA being so small as a factor.  John & I talked about the Republican platform suggestion that despite the language, commercial crew to the ISS would continue.  John suggested an early down select to SpaceX but I advocated for at least another round of competition with Sierra Nevada & Boeing, possibly others too.  Our final call was from Tim who talked about ion propulsion & space nuclear propulsion.  He introduced the idea of carbon nano tubes for use in rocket materials & I suggested that was way out in the future.  Tim also suggested the private sector bypass NASA & do its “own thing.”

Dr. John Lewis, Monday, 5-28-12

Guest:  Dr. John Lewis.  Topics:  Asteroid mining, Chinese space program.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, https://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed back Dr. John Lewis to discuss asteroid mining and the Chinese space program. You can order Mining The Sky: Untold Riches From The Asteroids, Comets, And Planets by Dr. Lewis as we talked about his book throughout our program.  If you use this Amazon URL, Amazon will make a donation To The Space Show/OGLF:  www.amazon.com/Mining-The-Sky-Asteroids-Planets/dp/0201328194/ref=onegiantlea20. Our first segment focused in on asteroid mining, where are today, its future, legal issues to be settled, risks, and more.  Near the end of this segment, we also talked about the Law of the Sea Treaty, the common heritage of mankind and revenue sharing ideas, all of which would be detrimental to asteroid mining and expanding space commerce.  Earlier Dr. Lewis referenced the Keck study, The Asteroid Retrieval Feasibility Study which says we can capture a certain size NEO and put it in orbit around the Moon. Dr. Lewis carefully went through the pros and cons of doing this.

In the second segment, Tim called in and continued the revenue sharing and common heritage discussion.  Dr. Lewis then cited his family history dating back to 1625 coming from theNetherlands with the West Indies Company, then staying here and moving west rather than returning to theNetherlands.  He drew parallels with this and potential space settlement and risk taking.  Next, we talked about the Chinese space program, their space station, the upcoming taikonaut launch in June and the fact that they are actually “bending metal” in making hardware for going to the Moon, unlike the Indian program which is still largely talk.  Near the end of the segment, we talked about lunar mining, the needed future vision and leadership, the need to be a multi-planet species and why.  Our discussion with Dr. Lewis is full of important information so I urge you to carefully listen to this program and use the internet to follow up on many of the topics and issues he brings to our attention.  For example, you might find it interesting to see the 1926 Plan of Space Exploration as developed by Tsiolkovsky (www.informatics.org/museum/tsiol.html).
