We welcomed Dr. Robert Kooima to the program to discuss his 3D imaging and software work, especially for the Moon and planetary bodies. Visit his website and www.kooima.net, then click on Applications, then click on Panoptic. This will enable you to follow along with our discussion. In the first segment of our 1 hour 22 minute program, Dr. Kooima started out by telling us how he developed the software he uses for his 3D renderings and images. Note that the software is freely downloadable from his website on the Panoptic page. Also, its Open Source and Dr. Kooima is interested in your feedback if you use it. His email address is on most pages of his website. Keep in mind if you do download the software, you still have to download the database & those are very large files as you will hear toward the end of the first segment. Dr. Kooima shared with us his motivation for doing this, then he explained the pixels and resolution and why the object needed to be spherical. Our guest was asked about side effects using 3D including Oculus Rift and here, our guest had much to say, plus he explained many of the problems by helping us to understand human brain perception. Listeners asked about computer power and faster speeds, latency and rover motion.

In the second segment, our guest told us about his YouTube channel and how to find it. He suggested we watch the “LRO & The Real Time 3D video as well as the “Tour of the Moon on the Oculus Rift.” BJohn wanted to know about the ability to image irregularly shaped objects such as Comet 67P. Be sure to listen to what Robert said about this. Other listeners wanted to know the ease of rendering 3D from the Moon or Mars, then someone asked about using all the radar and other data to create a 3D image of the surface of Venus through the clouds. Our guest talked about the complexities of atmospheric rendering and the fact that Moon had much more data available so it was by far the easiest to render. Dr. Kooima then brought up issues revolving the focus of an object as this is very important to the imaging. Another listener wanted to know if the path to this work was through computer science and graphics or astronomy. You might be surprised by his answer. Our guest also mentioned other software available including the USGS Isis Planetary Image Processing Software and the Celestia Planetary Software. near the end, I asked or guest where this field might be in ten years from now. Don’t miss what e said about the future, the time table, even the investment. Don’t miss his closing comments.

Please post your questions/comments on TSS blog above. You can reach our guest through his email address which is on most pages of his website.

Welcome to this Open Lines program in which many space topics were discussed by those emailing and calling today’s show. During the first segment of our very long 2 hour 37 minute program, I suggested several topics for discussion including Gliese 581d, topics suggested by listener Kirk in a before the show email, the SpaceX vs. Blue Origin patent litigation, and the recently held Pioneering Space National Summit with space settlement and cheap access to space as the consensus goals of the summit. To begin the program I read an email from a Portland listener wanting information about Mars One. Our first caller was Michael Listner who explained in some detail the ruling recently handed down by the court regarding the SpaceX vs. Blue Origin patent challenge regarding landing a first stage on a floating barge and restarting the rocket engine. Michael did a great job in walking us through the decision, what it means and what to expect next so don’t miss what he had to say about this important case. Blue Origin was granted the patent in 2013. Marshall called to talk about this being the year of the Dwarf Planet with Dawn and Ceres plus later on New Horizons reaching Pluto. Jon from NJ called and we talked about communicating over interstellar space given the story I reported on regarding Gliese 581d 22 light years from earth. We lamented the amount of time it would take to send signals back and forth were it an inhabited planet. Jon thought there might be faster ways of communicating using packets of data. He also suggested a themed Open Lines show, “Confessions of a Space Cadet.”

In the second segment, Kelly Starks called and was extremely controversial. First, let me say that Kelly’s statements, perspectives and views are not those of The Space Show, One Giant Leap Foundation, or me, David Livingston. They represent only Kelly and nobody else. The controversy came when Kelly compared working for old space as compared to New Space companies and then accused NewSpace companies of cutting corners for safety, compromising designs, etc. I strongly disagreed with Kelly through the length of his call and at times cautioned him in making unfounded accusations against his former employer. He said he could back up his accusations but as you will hear, I was very skeptical of his ability to do that and told him so. Toward the end of his comments, he mentioned his old ArcJet space plane project which died for lack of funding, interest, and support. He called back before the end of the show getting in the last call of the show to tell us more about ArcJet plus I told him if he had any material on it that was handy, I would upload it to the blog. For those of you interested in Kelly’s ArcJet project, I have uploaded two of his papers to the blog for this specific show so you can download them as you please. John from Ft. Worth called in to give a different “spin” and take to Kelly’s comments but I was not really accepting of John’s take on what Kelly had to say. Doug called to also talk about dwarf planets and suggested we might be in a golden era of planetary science. He said the Ceres white spot might prove to be very interesting if its water. Doug and I also talked about his concept of going directly to the Moon. At first I misunderstood what he was talking about but in the end we were both on the same page as to what he had to say about the issue and I thanked him for clearing up my confusion over his comments. I asked him for his views on what Kelly had to say but for the most part he just said it was not something he was interested in.

Please post your comments/questions on TSS blog. For those of you wanting to take issue or support what Kelly had to say, civility is required when posting on the blog. Ideas can be held up to the light of day and are fair game. Any posts lacking civility will be removed from the blog.

We welcomed Dr. Paul Davies to this 65 minute discussion about his contribution to the excellent book, “Starship Century: Toward the Grandest Horizon.” Other topics included interstellar travel, microbiology, human spaceflight, Mars, ET and much more.  We started our discussion with his Afterword in the “Starship Century” book and I asked him about his comments regarding microbes.  One quickly learns from reading his Afterword that it is not the propulsion and engineering that presents the greatest challenge to interstellar travel but what happens to essential microbes needed for life in microgravity and the space environment.  We learned that even in LEO such microbes can transform and become toxic to life.  This is a fascinating microbiology discussion regarding deep space missions to Mars, the Moon, and long interstellar travel. Don’t miss what Dr. Davies said about microbes as it opens up an entirely new study in human factors for human spaceflight.  Other issues we talked about included planetary contamination, microbial ecosystems, figuring out the minimal needed for sustainability regarding the good microbial environment.  Also, what microbes are crucial and those that might be irrelevant for the spaceflight passengers as well as for animals and plants needed for sustaining the mission.  Dr. Davies was asked that given microbiology being a bigger challenge than propulsion and engineering, were we close to having propulsion and engineering for interstellar travel.  You will appreciate his very “witty” answer to this listener’s question.  Faster than light travel came up and so did the work being done around the Alcubierre Drive.  Dr. Davies had much to say about faster than light travel, the speed of light, physics, and related disciplines.  In this discussion, we also talked about both black holes and worm holes.  Later, we talked about the possibility of life in the solar system other than on Earth.  You might be surprised by some of what Dr. Davies said, including the probabilities that Earth might have been visited over 100 million years ago.  Don’t jump to conclusions, listen to the discussion first.  Helen of Atlanta asked why bother with interstellar travel when we can’t even return to the Moon. Again, another terrific response by our guest.  More came up on the Fermi Paradox, the need to stay grounded in fundamental science but to have a vision and healthy skepticism.  Viking and Gil Levin came up regarding the possibility of life on Mars and the reluctance of NASA to do biological experiments regarding the possibility of life on Mars.  A listener asked our guest about ET conspiracy theories and government cover-ups.  In closing, Dr. Davies reminded us to have and conduct healthy speculation which means always staying in tune with fundamental science.  That is what separates speculation from fantasy, Kool Aid, and La La thinking.  As the program was ending, we talked some about his work in cancer research. Make sure you visit his website, http://cosmos.asu.edu.

Please post your comments/questions on The Space Show blog.  You can reach Dr. Davies through his website or me.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information.  We welcomed Kimberly (Kim) Arcand and Megan Watzke to the program to discuss their new book, “Your Ticket To the Universe: A Guide To Exploring The Cosmos” published by Smithsonian Books.  Visit their website for more information our guests and this amazing book, www.yourtickettotheuniverse.com/Index/Home.html.  Also check out this YouTube video for the book, www.youtube.com/watch?v=3-KamC0Plro.  If you order the book using this Amazon URL, Amazon will make a contribution to The Space Show:  www.amazon.com/Your-Ticket-Universe-Exploring-Cosmos/dp/1588343758/ref=onegiantlea20.

During the first part of our 90 minute discussion, our guests explained why they wrote this book and how they came up with its unique structure, format & famous person quote at the beginning of each chapter.  We talked about the pictures used in the book and a few of the items that stood out to me including “Taking an Alien to a Baseball Game” which helps us understand visible light along with all of the other types of light.  A listener with a copy of the book emailed in to ask about the use of the terms light second, light minutes, and light hours when describing objects in our Solar System.  Their discussion of Pluto as a dwarf planet came up in addition to my talking about the book as an excellent teaching tool for school libraries, students of all ages, even adults.  Our authors talked about art and I noticed the inclusion of the famous painting Starry Night in the book.  Don’t miss what Kim and Megan had to say about why Starry Night was used in their book and the overall subject of art, space science, aesthetics, and the night sky abundant with stars.  As our segment was ending, we talked about Mars analogs here on Earth such as Svalbard and Rio Tinto among the many Earth Mars analogs referenced in this book, plus the book’s astrobiology focus.

In our second segment, I asked our guests if space exploration was worth it and why.  Don’t miss what each had to say in answering the question.  We talked about the NASA budget, what is accomplished with the budget, and general population misunderstandings about the actual amount of the NASA budget.  I mentioned a TV documentary on the Dutch East Indies Company and the necessity of human exploration.  I asked our guests what they thought our world would look like had we sent robots out instead of humans in those very early and risky exploration missions.  A listener asked about the description of the book as both a coffee table book and a science book, and we talked about that hybrid description.  Near the end of our discussion, I asked each guest for their favorite place mentioned in the book where they would want to hang out.  You might be surprised by their choices.  Both Kim and Megan signed off with excellent closing comments that you will want to hear and remember.

If you have comments/questions, please post them on The Space Show blog.  You can contact both guests through their website, Twitter, and Facebook, as well as through me.
