We welcomed back John Strickland for this two hour discussion on a wide range of topics of interest to the NewSpace, commercial space, and space settlement audiences.  John started out by talking about the upcoming NSS ISDC Conference in San Diego from May 23-27.  For more information visit the NSS website, www.nss.org and click on the ISDC link.  Some tracks are still open for submitting abstracts so if this interests you, click on the appropriate link at the ISDC site.  During this part of our discussion, John talked about the NSS Roadmap and the planned coverage of it at ISDC 2013.  John was then asked about the deep space commercial and Mars ventures announced in 2012 and so far this year.  He said they were helpful to the overall space settlement agenda and explained how in his discussion comments.  He added that the Mars missions and Golden Spike were “laudable” but suggested we may not be ready by the time the projects give for doing the venture. He later said he would have spent the money differently.  Don’t his miss all his comments on these new commercial and HSF missions to Mars.  Our conversation then focused on the problems of sequestration and then John talked about heavy lift and SLS.  Our next discussion topic was Space Solar Power (SSP).  Here, John took us through a detailed analysis of why terrestrial solar and wind is not the best way to go, then he went through some of the characteristics of SSP and why it is the preferred way to acquire much of our energy. This is a detailed and at times marginally complex discussion but one you will want to hear.  In the end, he suggested we delay until we have the bigger launchers such as Falcon Heavy or bigger to make the launch component more economical.  His analysis included total energy needs for a city, Texas, the U.S., globally, etc.  It is a very instructive discussion.  Near the end, he said we should not put all our eggs in one energy source basket.  Listen to his solid explanation for this suggestion.

In our second segment, John talked about launcher reusability and more regarding SSP.  He introduced us to space logistics, commercial docking with cargo to the ISS, & the need for reusable deliveries, thus the RLV.  From here, he talked about fuel depots, mostly at Earth-Moon L1 and L2.  He explained the boil off problem, the cryogenic transfer problem, and the need for good insulation plus a cryo cooler.  Other issues in this segment addressed a lunar base, plausible time lines for accomplishing much of what our guest talked about, the Chinese space program and the complicated US-China relationship.  Near the end, a listener asked about a possible Texas spaceport per suggestions of SpaceX.  Tim called just before the end of the show to talk fuel depots, types of propellant for the depots and then he mentioned the VAPAK process (see http://ralph.open-aerospace.org/PDF/2009.04.14%20-%20HCG%20White%20Paper%20-%20VaPak%20Overview.pdf.)

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 John Strickland to the show to discuss cislunar space development, economics, transportation, SSP, and much more. You can read his latest The Space Review article, “Cislunar transportation: the space trucking system” at http://www.thespacereview.com/article/2221/1. We have also placed on The Space Show blog several images John referred to during our 96 minute discussion. We started the first segment by discussing what is needed in terms of supporting space infrastructure to establish a Cis-lunar space economy. In addition, we talked about heavy lift launch vehicles in general, expendable rockets, the need for RLVs and more. John said there were three basic vehicle needs, a crew vehicle, cargo vehicles, and tankers. At one point he said he would like to see a Dragon model as a tanker. This discussion then went to orbital fuel depots and our guest had much to say on the depot topic. Here, he brought up the idea of a lunar ferry and robotic missions using the RLV. A listener asked him for the biggest challenge to the ideas he was sharing with us and he said money!

     In the second segment, Doug called in and talked about John’s Space Review article per the above URL. Doug had several questions and challenges for John. Another listener emailed in questions relating to John’s trucking system comparisons. Later, Tim called to ask about electric propulsion and this took us to the Falcon Heavy topic, the need for RLVs, etc. Also, John referred quite a bit to Image #2 on The Space Show Blog, the LMO Waystation. We then addressed Space Solar Power (SSP).Guest:  John Strickland.  Topics:  Cislunar transportation and economics, SSP, and more.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com.

He said it would take from $50 billion to $200 billion for a 1GW base load, Ground based Solar or wind system. He then discussed what would have to change about how we do space to see SSP become a reality.  Tim also wanted to know about bypassing the Moon and going directly to a NEO.  John had much to say about using the incremental approach which included the Cis-lunar economic development we have talked about on this program and on other programs.  John’s closing comments with the Teddy Roosevelt statement were important one so don’t miss it.  Please post your comments/questions on The Space Show blog per above.  You can email John Strickland for his materials and with your questions at jkstrickl@sbcglobal.net  He then discussed what would have to change about how we do space to see SSP become a reality.
