We welcomed Chris Newman to the show to discuss British space policy, programs, their space industry and British space law.  During the first segment of our 88 minute program, Dr. Newman talked about space law and the space industry within the UK.  At times we compared British space law with that in the U.S., talked about the British interest in commercial space, space entrepreneurism and British government space as opposed to commercial space within the country.  As you will hear, British space is more about business and returns than government policy.  We also talked about social media and its value with some criticisms and supportive comments from me.  Mike Listner called and we did some comparisons with the British space law perspectives compared to American space law perspectives.  A listener asked if the British were fearful or concerned about the Chinese program and if they thought we might be in a space race with China.  Chris had interesting things to say in response to this question.  Chris talked about the role of the European Space Agency (ESA), competition from SpaceX with the Arianne rockets, and the ISS.  Toward the end of our segment, Alex emailed a question about the impact of our ITAR regulations on the British space, science, and technology industry.

In the second segment, I asked Chris how British citizens influence their government for space policy and matters as compared to what we do in the States.  Chris did explain the British system to us which is quite different , including their budget process.  Later I asked if the British government and people were enthusiastic about space companies, including Skylon with Reaction Engines.  You might be surprised by his response, especially when I asked if he thought the desired Skylon funding was possible.  We also talked proposed British spaceports and the possibility of British regulations on their developing space industry.  Later, George emailed in to ask if various segments of the British government competed for funding similar to what happens with the discretionary items in our budget.  Chris explained the process in more detail but the short answer was no as their budget process is quite different from ours.  Another listener asked more questions about competition in Europe from SpaceX.  Chris had much to say about this.  Other subjects discussed included a guess as to what future space missions will look like from the British perspective, more on the threat from NEOs, the global launch rate and Arianne making unrealistic market share projections, and the militarization and weaponization of space. Near the end, we talked about commercial space balloon/airship  projects like World View.  As for 2015 for British space, Christ told us to be aware of the May elections as that may set the tone for the space debate and programs for the future.  We agreed to follow up with Chris after the election to check on this.

Guest:  Keith Henson.   Topics SSP using laser rockets to lower the cost of space access.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com. Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

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 Keith Henson to the program to discuss the use of laser powered rockets for launching space powered satellites to help eliminate the use of fossil fuels as well as lower the cost of space access.  To assist in your following our discussion, check out this laser rocket graphic at http://bit.ly/Uj9Vw9.  Also, Keith has several related published articles on the OilDrum blog.  You can download and read his articles at www.theoildrum.com/search/apachesolr_search/keith%20henson. Finally, our guest has permitted me to upload his recent PPT conference presentation to The Space Show blog, “Laser Propulsion and Space Based Solar Power.”  Please be sure to check out this presentation by visiting our blog, http://thespaceshow.wordpress.com. During our first segment, Mr. Henson talked about the need for low cost energy and said that by using laser rockets and his SSP ideas, the cost for electrical power generation could be as low as 2 cents/Kwh to GEO.  We spent a good portion of our discussion debating Keith’s assumptions behind the 2 cents/Kwh.  I referenced my costs per my PG&E invoice and other listeners emailed and called in regarding their electrical costs per their utility bills.  Keith has asked for people disagreeing to let him know where he may be going wrong so please post your comments on our blog and Keith will respond. He said several times that he wanted your critique and comments.  Many listeners as well as myself pushed him on his assumptions, wanting more factual information on how arrived at his conclusions.  He has this information pending publication with the British Interplanetary Society so for the moment, its under pre-publication boycott but as soon as Keith clears it, I will post his material on the blog and announce it on air. Later in our initial segment, we talked about the laser rocket being a weapon. This discussion sparked lots of listener participation. We also talked about SSP for insitu use rather than power beaming back to Earth.  Keith brought up the new developments with Reaction Engines out of the UK. Here is there recent press release in case you missed it: www.reactionengines.co.uk/news_updates.html. Listeners did call in to tell Keith that SSP did not make sense for a variety of reasons, including not closing a business case, with or without laser rockets.  Jerry offered such comments as did Charles. Also, without consent, AT&T installed call waiting on the toll free line. I finally figured this out & edited out several of the comments & my complaint.  The matter should be resolved for all toll free calls moving forward but about 1hr 30 minutes into the program, you will hear a rough edit where I removed the call waiting rants.
     In the second segment, we continued debating Keith’s costs plus his ROI assumptions. Fusion came up for discussion as well as already existent successful powered sat beamed energy back to Earth.  Toward the end of our program, Keith talked about his target of reducing dollars per gasoline by using laser rockets and SSP.

Guest:  Mark Hempsell.  Topics:  Reaction Engines, LTD & their Skylon space propulsion system.  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 Mark Hempsell for Skylon updates and progress reports since his last visit on August 6, 2009.  During our first segment, Mark started with an update saying they are nearing the end of the technology development stage for their space vehicle system.  We then went back to the basics and he described the Skylon project for us.  Mark talked at length about the Sabre engine, the radiator, their SSTO plans, and more.  Several listener emails came in wanting to know about the market and business plan model for Skylon, the space tourism module and profile, and if it could be used for point to point transportation.  We learned that for cargo, Skylon flies without a crew.  With passengers on board, there will be a crew.  Also discussed were orbital characteristics for the vehicle, docking with the ISS and the new ISS docking standards which may present problems for Skylon. You can check out these standards at http://internationaldockingstandard.com.  Mark mentioned the various rocket fuels, tonnage to LEO and GEO, crew and passenger configuration, and the two day turnaround period.  In the second segment, we resumed talking about the vehicle operating costs.  Michael called in to talk about emergency landing options given runway constraints discussed in the first segment.  Next up was the thermal protection system (TPS) and we learned that the skin was a type of glass, silicon carbonate that can take1,000 C and that is why Skylon is black.  Later, we talked about funding, government subsidies, & private investment.  Mark got a question about using scramjet technology and he had much say about this.  Another topic was the flight profile and G-loads to be placed upon Skylon occupants.  Near the end, we talked about ITAR and potential U.S. investor investment.  Skylon test flights will likely be in 2020.  Our guest also talked about ESA and other organizational oversight.

If you have comments/questions, please post them on The Space Show blog.  Visit Skylon’ s website, www.reactionengines.co.uk.
