We welcomed back Erik Seedhouse to the program to discuss the new Second Edition of “Tourists In Space: A Practical Guide.”  In our first segment of our 1 hour 26 minute show, Erik told us that the second edition was about 80% new and that it would be released the end of August.  If you buy the book on Amazon, you can order it at the special pre-release price.  Also, be sure to use the OGLF portal explained in the archive summary statement, on the blog and on both TSS & OGLF websites.  If you purchase it using the OGLF portal, Amazon makes a contribution to The Space Show.  Erik opened with the manual part of the book and mentioned his suborbital training company, Suborbital Training located in Melbourne, Florida.  For more information on suborbital training, visit http://www.suborbitaltraining.com.  Next, Erik talked about the flight profiles for both the XCOR Lynx and the Virgin Galactic SpaceShipTwo.  I asked Erik for the top 3 or 4 challenges to the industry and he cited space safety as the largest challenge to overcome.  Other top challenges included the spaceship noise which will be very loud, vibrations, acceleration, and space motion sickness.  He talked about the impact mostly on the cardiac system.  Erik was asked about the use of spacesuits with by the various companies.  We also discussed orbital space tourism using the Dragon and then later using the Dream Chaser.  Erik was asked if spaceflight participant medical exams would be done by special doctors or one’s own doctor even if the doctor has no aerospace expertise or experience.  Before the break & in response to a question, Erik pointed out that the industry was on hold given the all the earlier “cry wolf” announcements about starting revenue flights.

 

In the second segment, Erik talked about going to space at the designated and approved altitude by the FAI in France, the official international record and standards keeping organization for space issues.  He pointed out that 50 miles was not space.  We talked some about the World View project, then our topic switched to spaceports here in the U.S. as well as those planned for outside the country. Erik raised some red flags given the spaceships are under ITAR control which might make it very difficult for them to be operated in a foreign country under present ITAR rules/regulations.   Orbital tourism came up for Dream Chaser, Dragon V2 and the Bigelow Aerospace habs.  In speaking about the industry, our guest pointed out how SpaceX was changing spaceflight by their success.  The Brownsville, TX proposed SpaceX spaceport got lots of discussion time and email questions.  Erik pointed out two commercial spacesuit design companies, Orbital Outfitters and Final Frontier Design.  Near the end of our program, point to point transportation was discussed as were the potential winners in the upcoming commercial crew NASA down select process.

We welcomed Dr. Ajay Kothari to the show to discuss first stage  and full rocket reusability.  During the first segment of our 1 hour 44 minute discussion, Dr. Kothari opened with references to his April 14, 2014 Space Review article, “Robust and Reusable.”  I suggest you read this article and have it handy as a reference as you listen, http://thespacereview.com/article/2490/1.  Dr. Kothari explained  his model and analysis process to evaluate the costs and economics for rocket reusability options.  Our guest goes through his models and scenarios for us, notes that they are only for TSTO rockets (2 stage to orbit), plus he identifies his analysis and software tools.  His analysis led him to understanding the importance of the First Unit Production Cost (FUPC) and how this is a killer without a high rocket launch rate.  Dr. Kothari then talked about the possibilities for space tourism.  As you will hear, he thinks much more of orbital tourism over suborbital tourism which is understandable when you see his costing, price points, percentage of net income being spent on the flight, & a few other parameters.  When asked if he thought orbital space tourism would be the economic driver for rocket reusability, he said he thought it had the potential to be a significant contributor to it.  Listener Paul asked him about the reusability penalty due to added mass for a reusable rocket.  Ajay said they addressed that in their model and suggested a reusable rocket capable of the same payload and destination as an expendable would need to be 2-4 times the size of the expendable!  John from Ft. Worth was a caller with many questions but near the end of this segment, he asked for Ajay’s thoughts on the SpaceX reusable system and process.  Our guest thought highly of the SpaceX effort, process, and concept.  We also talked about both flyback and boostback options.

In our second segment, Dr. Jurist called in and addressed efficiencies in the learning curve which benefit expendables over reusables though our guest was quick to point out that after decades we still cannot build on these learning curve efficiencies to move further out with expendables in technology and cost reduction.  Dr. Kothari and John spoke about the flight rate b/e point which is largely unknown.  I then asked our guest about full rocket reusability and his ideas for a hypersonic second stage to orbit and back.  Dr. Kothari spent time with us during the balance of our program discussing his concept.  We even discussed point to point transportation as a result of this model and he suggested the innovative idea of combining limited orbital space tourism with Point to Point to make it more acceptable. Don’t miss his explanation of this idea.  Tim called in wanting to know about landing large payloads on Mars , possibly using inflatables or magnetic fields generated by a hypersonic in the Martian atmosphere. Doug was our last caller asking about rarefied gas flow & possibly returning to Earth from the Moon with a lighter weight heat shield, even what bouncing off the Earth’s atmosphere meant for Earth capture of the incoming spacecraft.  Our guest talked with him about this along with steady flow or steady heat conduction.  To conclude our discussion, Ajay summarized his models that closed the business case for orbital space tourism, including the one model that could not close.  Note the parameters he talks about for each model.  For more information, check out Dr. Kothari’s website for Astrox Corporation (www.astrox.com).

We welcomed Dr. Pat Hynes back to the program to discuss this year’s ISPCS.  During the first segment of our 1 hour 58 minute program, Dr. Hynes introduced us to this year’s symposium which is in Las Cruces from Oct. 16-17.  For detailed symposium information, registration, and more, please visit http://www.ispcs.com.  Pat started by telling us about attending a Virgin Galactic event in Mojave last week, including aspects of space medicine applicable to Virgin and human spaceflight.  Next, Doug called on his way back from Vandenberg and he told us about seeing the Falcon 9 launch and his impressions, then he asked Pat about the suborbitals ramping up for orbital spaceflight and if that was in their plans.  Pat said yes, talked about Point to Point Travel, some of the challenges, and orbital HSF in general.  I also added some information to the discussion.  During the balance of the first segment, Pat went through the first day of panels at the symposium offering highlights and insights not listed on the website.  Later, she talked about speaker John Gertner and his book, “The Idea Factory,” which addresses Bell Labs and innovation.  Pat referred to this book, Bell Labs and Innovation several more times during our discussion.

In the second segment, we picked up with the Wednesday afternoon program featuring Sandy Magnus, Executive Director, AIAA.  The importance of Innovation remained a key thread in our discussion and it is a major theme of the symposium.  During the balance of the second segment, Pat guided us through the agenda, again providing us with insights not listed on the website.  We also talked about the social and networking aspects of the conference which are outstanding!  IP was also discussed and the subject, including patents, is part of the symposium agenda.  We also talked a lot about NASA Flight Opportunities.  Near the end of our discussion, Pat talked about the tour of Spaceport America for Friday, Oct. 18.

Please post your comments and questions on The Space Show blog URL above.  You can contact Pat’s office for more information by calling (575) 646-6414.

We welcomed Rob Lowe to the program to introduce us to and discuss ShipInSpace, a new entry in the suborbital space tourism industry.  During the first segment of our 1 hour 24 minute program, Mr. Lowe introduced us to ShipInSpace, he described their proposed space tourist flight adventure program, we talked about the vehicle, the entry and reentry g forces, the stacking system for passenger pods and the safety escape system.  Rob also described a typical parabolic flight profile for ShipInSpace once it starts operations in five years.  Rob answered questions about vehicle safety and certification, their two year passenger training program, the vertical launch and horizontal landing design, the hatch closure and opening procedures, plus the use of space suits for the occupants, and their pricing model which is significantly lower than their competition.  Rob also addressed listener questions about ShipInSpace financing, budgets, and the start of ticket sales.  Crowd funding was brought up in the financial discussion, our guest was asked about the competition not only from Virgin and XCOR but from other companies in the U.S., Canada, and across Europe. One of our listeners in India wanted to know how ShipInSpace was different from the AXE APOLLO space project.

In the second segment, Rob was asked about choosing one’s pod mates for the flight given each stacked pod had room for four passengers.  We also learned that initially the flight frequency would be weekly but that might increase over time.  Rob digressed to tell us about his book which is available on Amazon, “The Eccentric Universe.”  Remember, if you buy the book using The Space Show/OGLF Amazon portal (instructions are in all show summaries on the website and the blog plus the blog has a specific link to our Amazon portal), Amazon will make a donation to The Space Show/OGLF.  His book sounds most interesting so check it out. Later, our guest was asked about the possibility of their using Spaceport America and our guest indicated that it was a possibility, as was the use of spaceports in Europe and elsewhere.  Near the end of our discussion, Rob gazed forward with an assessment of the potential of a future space tourism and development industry, then a listener asked them about plans to move toward orbital tourism.  We asked our guest about their proposed flight test program, Point to Point transportation, and a few more questions about their competition.  The last listener sent in an email saying he was a skeptic and wondered about their Plan B if the marketing survey they are counting on turned out to be invalid.  In response he said that the company and the spacecraft were designed to do other types of mission so not to worry. He also cited the demand Mars One has experienced in opening up the application process for their mission as solid evidence of the interest in space tourism and travel.

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, 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 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.
