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.

Welcome to our Golden Oldie Decade of Review, this year with the space year 2011. Tom Olson was our reviewer for this 2011 review, aired live on Dec. 27, 2011.  We had much to cover in this 105 minute program. Tom started out reminding us that 2011 was the 50th anniversary of human spaceflight. He told us about the banner year for Yuri’s Night parties around the globe celebrating this important milestone and specifically about the even he attended in New Your City. Next, he pointed out the recent National Press Club talk given by Elon Musk on going to Mars and building the rockets to take us there, plus his recent New Scientist interview which you can read in full on the Mars Society website. Tom commented that the sky was actually falling in 2011 with two large junk satellites coming back to Earth. We also talked about the return of Phobos Grunt to earth probably in early to mid-January 2012. One of the big events we discussed for 2011 was the retirement of the shuttle. This led us to discussing the recent Chinese space rendezvous and the fact that China is now the number two launching country behind Russia having overtaken the U.S. this year. Planetary missions were part of our year in review with Vesta and Dawn, the Kepler Space Telescope, MSL with Curiosity. New Horizons continued its journey to Pluto and Explorer 1 continued beyond our solar system. Tom talked about SLS and the ORION MPC Vehicle, plus the James Webb Space Telescope and its cost issues in the context of its impact on the NASA budget. Soyuz rocket problems along with all the Russian rocket failures this year were fair game for our discussion. I asked Tom what he thought of the idea of SLS as a place holder for skill sets and technology until our space program improves. Don’t miss his answer. He brought up Virgin Galactic’s drop tests this year, especially the last one where trouble showed up. Making news for 2011 were NASA and space industry workforce layoffs and the successful Falcon 9 and Dragon launch. At the end of the first segment, Bigelow Aerospace was in our spotlight. In segment two, Tom led off with XCOR news, Terry called wondering about CCDEV3 and Tom suggested program winners! Don’t miss his prediction. He also was asked to predict the cancellation year for SLS. Don’t miss this prediction as well. We talked about the upcoming New Space Business Plan Competition for 2012, the prizes which are the largest ever, and the timing. If this interests you, make sure to stay tuned for more information. Later in the segment we began a summary of our discussion and 2011. Tom was asked about the space elevator and the Lunar Space Elevator. We wrapped up our discussion talking about growth in the space conferences even in the tough economic year of 2011.

We welcomed Robert Sackheim to the program to discuss NASA, commercial space, the current state of rocket propulsion and advancements in the field.  During our first segment of this 1 hour 47 minute discussion, Mr. Sackheim talked about his background and experience at TRW, NASA MSFC, and his current consulting.  I asked him several questions about the current state of rocket propulsion. Bob had much to say about this, focusing on chemical rocket propulsion, satellite propulsion, electric propulsion, and the need for nuclear propulsion.  He talked about booster rockets, various rocket stages and their propulsion, rocket engines, and even SRBs.  Several questions came in asking him if we had the current technology for HSF to Mars or even the Inspiration Mars flyby mission talked about so much in the recent press.  Listeners wanted to know if our current levels of propulsion were up to the task.  After a rather thorough propulsion discussions, Bob turned to commercial space, lowering total space mission costs, regulatory policy, and commercial spaceports.  He also talked about budget issues and raised the question a few times as to why ten NASA centers were needed given their often overlapping, competitive, and duplicate work.

In our second segment, commercial space took the lead with a discussion on public/private partnerships & the belief that Americans can do anything if we set our mind to it, including space travel.  Of course here the problem as we know lies in leadership and today it appears that leadership in space & other areas is sparse at best.   Bob then focused on geo satellites and the increasing development and capabilities applicable to cubesats.  HSF came up for discussion as did the robotic missions. You might be surprised by what our guest had to say about HSF.  Other issues in this segment included the lunar space elevator, the congressional and NASA track record in canceling ongoing projects & taking lessons from history, SSP, & ways to reform & move NASA forward.  Bob spoke about evolving toward the old NACA model.  I asked about the impact of space advocacy from his perspective given his leadership experience and past positions in leading organizations and projects.  We also asked him about space tourism and hybrid rocket engines. He had much to say about hybrids, don’t miss the discussion.  Bob talked about the Falcon rockets, testing including static fire tests, and SRBs as related to the Constellation project and safety.  Toward the end, our guest was asked about NewSpace, fuel depots, & cryo transfer.  For closing comments, he talked about commercial space being the way to go & the path to our space future.

     We welcomed back Michael Laine for LiftPort Group updates regarding the lunar space elevator.  For more information, visit www.liftport.com.  Michael started our two hour discussion talking about his very successful Kickstarter campaign last year.  LiftPort started the campaign asking for $8,000 but raised $110,000!  During this first segment, Michael talked about the plans to use the $110K, the experiments LiftPort would do and why additional funding was needed to advance the lunar space elevator project.  I asked Michael lots of questions about the lunar space elevator market, his time table for transitioning away from being a Power Point project, & the LiftPort labor force.  LiftPort is mostly volunteer labor. For now it is working on tether and balloon experiments.  We talked extensively about using Kickstarter and even talked about the tax consequences for Kickstarter revenue.  Michael did say that he thought the project would be a private project in that government would not be a major supporter, if at all.  Michael then talked about his fact finding global missing seeking new financing and partners after the Kickstarter campaign. He had much to say about his visit to Iceland and the company CCI Games.  When pressed, Michael suggested 8 years from last August to completion. Listen to the details supporting this timeline.  Michael also outlined four areas needing resolve to move the lunar elevator project forward.

     In our second segment, Michael described more of the elevator project, including the use of EML1 and why & how the elevator ribbon would work, including its logistics from EML1 to the lunar surface and EML1 back toward Earth.  He also talked about their lunar surface elevator contact point on Sinus Medii.  A listener asked him about the Google Lunar XPrize & Michael told us how a GLXP mission could benefit the LiftPort project.  Also in this segment, we talked about costs.  Michael estimated about $800 million for a robotic mission and maybe up to $1.2 billion for three astronauts roughly every three weeks.  He compared these costs to the cost of shuttle launches and flights to the ISS.  When asked about lunar markets that might economically justify the lunar elevator, he talked about the potential of HE3 mining and new uses for the material here on Earth, plus lunar SSP and solar panel manufacturing.  Alex asked Michael to be specific about the transitional steps from Power Point to the beginning of a systems engineering project to develop the elevator.  Emory emailed in more questions about tether use, Tim called (sorry for phone line issues on Tim’s call) regarding tethers and more.  David Ben wanted to know about the Falcon Heavy and I expanded that to include SLS.  A question came up about LiftPort’s interest in a Mars space elevator. Our discussion concluded with Michael suggesting that Kickstarter & similar crowd source funding organizations will play a bigger & more important role in funding space ventures in the future.

During the first hour of the webinar, Dan took us through the trajectory analysis to Earth-Moon L2 per his PDF document.  We talked about why EML2, libration points in general, and how such missions are planned.  If the resolution on the webinar video for the charts and tables used during this segment are difficult to read on your computer, please bring the document up on the PDF on The Space Show blog and follow along that way.  Dan took us through Table 1, HALO orbits, and the HOI as well as the Trans-Lunar Insertion points.  We talked about orbital characteristics, delta V, rocket size, and more  We also talked about the position of the Earth, launch windows, the Moon, & other factors influencing the planning of the mission.  While at times the discussion may seem a bit technical or overwhelming for those of us having never done mission planning at this level before, all of us will certainly have a better understanding of the factors considered and influencing both robotic as well as human spaceflight missions.  Near the end of the segment, we talked about the SLS and heavy lift & how payload capacity interacts with mission & trajectory analysis. 
 
     In the second hour of our webinar, Dan took us through his HD movie of the orbital trajectory talked about during the first segment, stopping it at intervals for specific explanations and questions.  The movie is in the QuickTime format but you can see it both on the webinar or by using the URL provided on the blog.  We took several listener calls & questions.  One asked Dan about the differences in planning for the robotic vs. the HSF mission using MSL & Curiosity as an example.  Dan pointed us to a YouTube video he made a few years ago with Dr. Logan using these tools for a Deimos mission (www.youtube.com/watch?v=X10GAqA4Ky4). Another listener called wanting to know the likelihood of an EML2 mission actually happening.  Dan explained why he believed this mission to be the next stepping stone in HSF.  More was discussed about SLS with Dan raising some concerns about its real capabilities & wondering if Congress is being sold unrealistic expectations. We talked about heavy lift in general & with the support of properly placed depots.  SLS and the difference with a Falcon Heavy were also discussed in terms of what the differences would mean in payload, number of launches, costs, risks, etc.

Open Lines, Sunday, 10-7-12

http://archived.thespaceshow.com/shows/1867-BWB-2012-10-07.mp3

Guest:  Dr. David Livingston.   Topics:  Open Lines discussion on various space topics per the choice of the listeners calling today’s show.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://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. Welcome to today’s two hour 15 minute Open Lines discussion.  The program was in three segments but as we focused on just a few topics for the entire discussion, this summary will not be divided by segments.  I started the discussion by describing upcoming Space Show programs, then putting out a few discussion topics.  As it turned out, the dominant topic discussed by the listeners had to do with astronaut safety and the recent program with guest Rand Simberg from Monday, Oct. 1, 2012. Rand talked about our being too risk averse, the need for more lives to be at risk to do valuable space missions, etc. You can hear his program at http://archived.thespaceshow.com/shows/1863-BWB-2012-10-01.mp3. Several callers took issue with much of what Rand said and for the most part thought that space missions were valued and that human spaceflight was already risky.  Listeners went back and forth on this topic across all segments of the program, talking about shuttle accident rates, proposed accident rates for Constellation, Orion, Dragon, and more.  Some listeners even talked about aviation safety rates, military jets, and the track records of the Atlas 5, Delta IV, and Arianne V rockets.  For part of this discussion, we also talked about the liability limitation laws passed in spaceport states including California which recently signed into law its version of law. We talked about what this might mean for the industry, for spaceflight participants, and even if the would hold up in an accident.

As part of the HSF safety discussions, we also talked about launch abort and escape systems.  We took a call at the first of the second segment from Charles in Oregon who  wanted to talk about the lunar space elevator, SLS and propellant depots, our second most talked about topic for the day.  Charles is a strong proponent of the lunar space elevator and depots, but others called in from the skeptical side of things which was my position.  At times the discussion switched to the space elevator here on Earth but everybody agreed that the lunar space elevator was much more doable. I kept challenging Charles and proponents of this and the depots to show me the complete and thorough financial analysis and trades for these missions with assumptions as that would be the only way to know if these concepts had legs to stand on.  If Charles does get me some of this documentation and its viable, I will use it in a future Space Show program.  Tim in Huntsville wanted to know my thoughts on various alternative launch systems & my preferences for which type of space missions.  There were other topics scattered throughout our program including the 23 mile skydive by Felix Baumgartner with Red Bull scheduled for Oct. 8th, fusion propulsion, and the SpaceX launch going to the ISS later today.

     If you want to email any of the callers to this program, send your note to me and I will forward it for you.  Please post your comments/questions on The Space Show blog URL above.

http://archived.thespaceshow.com/shows/1851-BWB-2012-09-09.mp3

Guests:  Dr. Bryan Laubscher, Victor Cummings.  Topics:  The space elevator screenplay, “High Lift.”  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://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 and for the first time Victor Cummings to discuss the space elevator screenplay, “High Lift.”  This screenplay won the ScriptVamp 2011 Dream Quest: Feature Screenwriting Competition and was the Grand Prize Winner.  Visit

https://scriptvamp.com/Victor_E.html for more information about the screenplay and the competition. Visit the High Lift website at www.highlift.us.   Victor started our discussion by providing us with his background that took him into the screenwriting profession. He talked about challenges & screenplay issues plus the differences in a screenplay compared to other forms of writing.  Both Victor and Bryan told us some about the story line, the plot and as a result of my pressuring them, the villain!  The space elevator is considered to already be in existence in the story and there are space elevator centers for different purposes and destinations.  As you will hear, using the space elevator is key to solving the global warming problem and saving the Earth.  Both our guests talked about reviews and oversight from professionals, agents, etc.  They told us how they had to remove much of the science jargon and focus the screenplay on a younger and more generally educated audience.  Listeners asked several email questions about the science fiction genre in screenplays as well as target audience and marketing concerns.  Our guests talked quite a bit about the issues in getting an agent, making that first sale, and capturing an audience.  We also talked about science fiction usually being bigger in the budget area and more costly, probably due to technical special effects.  Near the end of the first segment, a listener wanted to know if a successful screenplay and movie would further interest, funding, and development of the space elevator project.

In the second segment, we talked about markets and the need to break the circular loop of needing to have a sale but needing to have an agent but first needing the sale.  We talked about their winning the ScriptVamp competition per above and raising money for their project through crowd sourcing, particularly Kickstarter.  A listener suggested our guests attend the well known Maui Writers Conference and another brought up the Darpa 100 Year Starship Program.  As our program was drawing to a close, Victor and Bryan asked for help with Hollywood type contacts for their screenplay.

If you want to contact Victor and Bryan, send your note to me and I will forward it to them both.  Please post your comments/questions on The Space Show blog per the above URL.

Homer Hickam, Friday, 4-13-12

http://archived.thespaceshow.com/shows/1751-BWB-2012-04-13.mp3

Guest:  Homer Hickam.  Topics:  We discussed his new book “Crater” & how he developed the technologies & systems to make living on the Moon credible.  You are invited to comment, ask questions, & discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, & any discussion must be relevant & 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 Homer Hickam to the program to discuss his new book “Crater” & his new Kindle book, “Paco: The Cat Who Meowed in Space.”  You can buy each book from Amazon using these special URLs & Amazon will make a contribution to The Space Show/OGLF:  For “Crater,” use www.amazon.com/Crater-Helium-3-Novel-Homer-Hickam/dp/1595546642/ref=onegiantlea20.  For “Paco,” use www.amazon.com/Paco-Meowed-Kindle-Single-ebook/dp/B007K1OC6K/ref=onegiantlea20.  Homer explained that Crater (set 120 years in the future) was a teenage orphan working to mine HE3 which was sent back to Earth as Earth desperately needed it for fusion energy.  While telling us about his book, we learned that Homer created solutions to many of the challenges to living on the Moon.  For example, microgravity & radiation – listen to how he solved the problems.  Muscle deterioration? He solved that one too.  Transportation back & forth between Earth & the Moon?  That one too.  Spacesuits, the use of one atmosphere, all sorts of other challenges to our having a lunar settlement have a solution to make the Crater story credible.  As you will hear, not only does Homer go into detail about the storyline, but he focused on the solutions & this makes the story both believable & credible.  Issues such as lunar dust, children on the Moon, even pregnancy, well, there is a solution.  Food & water too.  We did go off the topic of his books to ask about space policy.  As you will hear, Homer thinks the Moon will be developed by entrepreneurs for commercial value.  He sees companies such as Space X changing the game for our space policy & does not see government space programs being what they once were though development of needed infrastructure is part of what government can & should do.  The lunar transportation systems he talked about will be private commercial businesses.  When asked how he came up with solutions to problems encountered when living on the Moon, he talked about a study he did in the 1990s which is on his website, www.homerhickam.com. Homer was asked why the Moon & not Mars.  Don’t miss his response to this listener question. We also talked about the space programs for other countries such as China. Homer then told how he envisioned the world to be 120 years in the future. As you will hear, countries have broken up into smaller, more manageable nations, including the United States.  The world is not as we know it today.  Toward the end of the first segment, Homer was asked about the difference in times from when he grew up in W. Virginia to today given the listener said his son could not even fly an Estes rocket in their city. Part of his reply stressed the need to join rocket clubs today.  Before the break, we talked about insitu resources, water, food, law, & justice on the Moon.

During our short second segment, Homer was asked about strip mining on the Moon & he had much to say about it. Don’t miss this discussion.  He was also asked about other uses for the Moon besides HE3 including solar, radio telescopes, & manufacturing.  As the show ended, he commented on the need to have better political leadership to lead us forward in space development. He also had more to say about slime mold which plays an important part in his book.

Please post your comments/questions on The Space Show blog.  Mr. Hickam can be contacted through his website.

We welcomed Michael Laine for updates on his company LiftPort & their latest space elevator plans.  Michael started the discussion with an overview of his involvement in the space elevator project, his company LiftPort up through its fiscal problems, the reestablishment of the company with intellectual property, & a lunar space elevator study from 2010-2011.  He brought us current with LiftPort plans into 2012 plus what the company & his team have planned for the balance of the year.  Michael talked about his team, issues relating to a lunar space elevator, how the Moon rotates/spins differently than the Earth, & how an elevator would be different than an Earth-based elevator which he said cannot be built at this time.  He made the point that the lunar elevator could be built now, does not need a carbon nanotube ribbon & will likely go from Sinus Medii on the Moon to an orbiting spaceport at the Earth-Moon L1 point where there might be a Bigelow station with EELV or Falcon 9 flights coming up from Earth.  He also said the early flights would be robotic but that both capability and capacity would expand to include humans.  He was of the opinion that the basic lunar space elevator could be completed within a decade.  Eric called in to challenge some of Michael’s technical analysis.  Michael offered to send the math analysis of the project to anyone requesting it.  His email address can be found at the end of this summary.  Later in this hour long segment, I asked Michael about business issues, the market, financing (public, private, both), ROIs, & more.  As you will hear, this part of the LiftPort plan is unfinished.  Michael’s team has been confirming the math analysis for the project & has yet to refine their business plan/due diligence analysis. When pressed, he said the cost might be around $700-$800 million but they were increasing that to $1.5 billion to be a bit conservative.  He also said this was for a small elevator with a payload capacity of 40-240 kg.  In speaking about the commercial aspects of the project, he repeated many times throughout our discussion that they were focused on cash flows and the commercial aspects but first they needed certainty about reaching the technical “go” point.

In our second segment, Michael continued his theme that they do not yet have the business plan components in place.  I then asked if this was nothing more than a feasibility project?  That seemed to summarize our discussion so far.  Michael did point out that LiftPort already had two intellectual property (IP) assets so the company was positioned to make money even before the elevator project got going beyond the study phase.  I pressed him for his public finance plans.  His idea was based on the Railroad Acts which included bond sales guaranteed by the government with the government providing sufficient business revenues to support the bond guarantee.  A listener brought up the issue of space debris & climbers.  Michael pointed listeners to their YouTube channel to see their climber in action.  Mars elevators were mentioned near the end of the program as well as LiftPort internships.  We also talked about the recent Japanese company’s announcement of their own elevator plans (Obayashi Corp.).  Michael also suggested the space elevator conference (http://spaceelevatorconference.org).

Welcome to this 2 hour 20 minute Open Lines discussion largely driven by listeners calling the program.  In our first hour segment, I listed the usual possible discussion topics which I won’t repeat here. As to be expected, listeners had their own ideas as to what they wanted to talk about though we did address some of the issues I previewed including NASA & the treatment of their chimps in the early space program given that PETA wants to establish a chimp empathy museum at KSC,  NASA budget cuts & the recent congressional hearings, the Defense Intelligence Agency Chinese space program wake up call, & more. The congressional hearings of last week made it to our discusses as listeners focused on what was said by Senator Nelson, Senator Hutchinson, NASA Administrator Bolden, & Dr. Tyson in his short presentation. Listeners also talked about the comments by Texas Congresswoman Eddie Johnson regarding commercial space/crew on the House side. Also in the first segment, Tim called in to inquire about a possible IPO for Space X.

In our second segment, Dr. Jurist called in to express his disappointment at the elimination of funding for the Operationally Responsive Space office/program.  This took us to a discussion about national security space & I asked Dr. Jurist about the Defense Intelligence Agency wake up call regarding the Chinese space program as expressed by their director Ronald L. Burgess.  Somehow we then got off on the topic of the planned retirement of the B-52 in 2040, about 88 years after it became operational.  While Dr. Jurist was talking with us, Tim sent in several email questions for him on microgravity experiments to determine what level of gravity was needed for humans for space settlement & long duration flights.  John Hunt followed with comments about VASIMR, nuclear propulsion, & even fusion powered spacecraft down the road in our future.  Tom Hanson of the Living Universe Foundation called in to let people know they are seeking Foundation board members (www.luf.org/contact).  I then introduced another topic from a current article in Popular Science, a 20,000 mph train to space (www.popsci.com/technology/article/2012-03/all-aboard-20000-mile-hour-low-earth-orbit-express).  This article refers to a newer version of StarTram & this brought in several more callers including Trent from Australia. Other listeners chimed in on the train to space idea as well though most did not take the article very seriously.  I introduced the news that Turkey had agreed to the Moon Treaty & then Terry called in at the end to talk about the X-37C & that it might become a crewed vehicle.
