We welcomed Dr. Bryn Laubscher back to the program for our 2 hour 22 minute discussion about carbon nanotubes and the Space Elevator.  During our first segment, Dr. Laubscher talked about carbon nanotubes, the manufacturing process, how to move the process and technology forward, end uses for the product, possible timelines for advancement and the current day use of Chemical Vapor Deposition (CVD) in the process.  Bryan talked about the need to find a better process for making carbon nanotubes than CVD.  Later is this segment, Dr. Laubscher was asked about the potential relationship to space other than with the space elevator.  This was an interesting discussion , don’t miss it.

In our second segment, Bryan talked about how hard and challenging the space elevator was and later in the segment, due to a call from Pooley, we went through many of the top challenges faced by the elevator with a status report on each one.  As this segment was opening, I did ask Bryan for a time line for space elevator advancement.  Our guest suggested that at some point, there would be significant demand for the elevator.  Next, we talked about the upcoming International Space Elevator 2014 Conference to be held at the Museum of Flight in Seattle, August 22-24, 2014.  For conference info, visit http://www.spaceelevatorconference.org. John from Ft. Worth called to talk about materials, composites and much more. We also talked about the strength needed for the elevator ribbon and John asked about SSTO.  Blaze emailed us about nuclear waste and Bryan had an interesting take on it. This was another valuable discussion, don’t miss it.  Dr. Laubscher talked about ribbon length, characteristics, strength needed, and its location in space, plus the counter weights it would need.  Adrian emailed several questions to us about the ribbon breaking and related issues.  He also asked our guest radiation issues.  Doug emailed about ways to climb up and down the ribbon.  Some of the other issues that came up were wind, lightening, ribbon oscillation, space debris, policy & regulatory issues.  As our program was ending, Bryan offered us words of wisdom and said his company website was http://www.odysseustech.com.  In addition, Dr. Peter Swan emailed us about his paper on the elevator which you can download and read at  http://www.virginiaedition.com/media/spaceelevators.pdf.

Open Lines, Tuesday, 8-21-12


Guest:  Open Lines with Dr. David Livingston.  Topics:  Space policy, STEM, Curiosity, Mars Society Conference, SLS, heavy lift, sequestration, & more.  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. As I started the first segment of this 2 hour plus Open Lines program, I identified some news items suggesting that some listeners might be interested in discussing them.  Not so.  Our first caller, Patrick from Quebec, debriefed us on the Mars Society Conference in Pasadena, the Curiosity landing & JPL as well as some of the main conference keynote speakers.  You can see the videos of all the keynote speakers from this conference at www.youtube.com/playlist?list=PL57B8D5FFF5B55A62. In telling us about the conference, Patrick focused in on the talk given by Elon Musk.  Later, Patrick mentioned his visit to the largest ground based optical telescope on the East Coast, the Megantic Observatory.  Charles Pooley called in next to continue to raise issues about the NASA Nanosat Challenge.  If anyone knows anything about it, do let us know.
We started the second segment with a call from Brett in Philadelphia to talk about his efforts in STEM and student space outreach.  Check out the website he talked about regarding “How to be a Rocket Scientist or Aerospace Engineer” at www.squidoo.com/how-to-be-a-rocket-scientist-or-aerospace-engineer. Your suggestions on additions to his lists are welcome.   Our next caller, Doug from S. California, offered us some comments from the recent program featuring Chris Carberry and humans to Mars.  He talked about going back to the Moon but as part of a mission to Mars.  He also talked about the Carberry comments regarding the upcoming 50th anniversary of when we left the Moon for the last time, suggesting we turn it into a positive statement for the future.  In addition, we talked about the viral JPL video, “We Are Nasa And We Know It” at www.youtube.com/watch?v=QFvNhsWMU0c. Our next caller was John from Atlanta.  He responded to my request that listeners tell us if they thought space would make it into the presidential campaign as an issue. John did not think it would but check out his comments on this subject.  John also took issue with an earlier caller pertaining to Elon’s comments regarding rocket reusability, Falcon Heavy, a reusable Falcon 9, and SLS.  Our next topic was sequestration and I talked about the report by Dr. Fuller at George Mason University which details job losses in all states in DOD and space related work if sequestration is allowed to take place.  You can download this excellent study/report at www.aia-aerospace.org/assets/Fuller_II_Final_Report.pdf. As we were drawing to a close, both John and Doug called back to clarify statements and positions spoken about earlier in the program.
Please post your comments on our blog.  If you want to email anyone who participated in our discussion, send your note to me and I will forward it to them.

Dr. Bryan Laubscher, Monday, 7-16-12


Guest:  Dr. Bryan Laubscher.  Topics:  The Space Elevator and the upcoming annual elevator conference.  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. Bryan Laubscher for our annual space elevator update program.  Our first order of business was to discuss the upcoming Space Elevator 2012 conference.  Check it out at www.isec.org/sec.  Registration, hotel, programming, speaker, and session information is provided on the website.  Dr. Laubscher noted some differences this year including its location, the Seattle Museum of Flight.  Also, the Family Science Fest on the conference first day.  Bryan highlighted some of the sessions including those dealing with elevator operations and alternative launch options including Stratolauncher.  We fielded several email questions from listeners and then Michael called in to ask about security requirements for the elevator.  This turned out to be a most interesting discussion but one leaving us with lots of unanswered questions. In discussing elevator security, we talked about international law, the proposed Law of the Sea Treaty, offshore oil platforms, territorial water issues, DOD and department of Navy defense actions, and more.  Tony emailed in a series of questions including one that asked about the rotovavtor.  Later, I asked Bryan if elevator security should be a taxpayer responsibility and he said yes, noting that revenues from the elevator along with taxes paid would be in excess of security costs.  We then talked about the elevator being an international project or an American project.  Bryan preferred American but we talked about both sides of this issue.  Bryan also had lots to say about materials and the CNT ribbon.  He told us about the detangler and the size of the ribbon, plus the incremental plan in ribbon development.  We asked Bryan timeline questions and it was also said that the biggest problem other than materials waiting to be solved was the surface to LEO transportation.

In our second shorter segment, we talked about inspiration, the need to learn systems engineering, and the absence of congressional political support for the elevator.  A listener asked about the payload capacity which Bryan said was 20 tons.  He mentioned spinoff technology including energy storage.  Terry wanted to know how scalable the elevator concept was and Bryan mentioned progress with climber reusability issues. In our summary, he said the overall biggest challenge still remained the materials.
