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 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.

We welcomed back to the program Dr. Dennis Bushnell, the NASA Langley Research Center Chief Scientist.  Dr. Bushnell discussed his paper, “Advanced-to-Revolutionary Space Technology Options-The Responsibly Imaginable.” which can be downloaded at http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20130011698_2013011376.pdf.  In the first segment of our 1 hour 26 minute show, Dr. Bushnell summarized the findings in his paper and talked about how we are still building on technologies from the 50’s and 60’s that were based on “living better with chemistry” and ICBMs.  We began talking about advanced propulsion including nuclear, but our guest made it clear throughout our discussion that what was needed was a reduction in the cost of space access by a magnitude of 10, not by two which is what is happening with new commercial rockets coming on line.  In fact, later in the show when discussing commercial space, Dr. Bushnell was clear that to close a commercial space business plan the reduction in launch costs by a factor of ten was absolutely essential!  I asked our guest to tell us where the bottlenecks were and he said it was in the culture & big cultural changes were required to move forward.  He also talked about the need to experiment and try lots of options and ideas, to triage them, down select, fly them, and choose the best based on the engineering process he described.  We talked about the low technology readiness level (TRL) of many of today’s space ideas and technologies, that we have become focused on instant or near instant gratification but that the process he was talking about would extend over a 25 year period.  Given this, his paper is a frank and factual discussion of many of our space industry segments, a no nonsense, no Kool Aid TRL analysis of much of what we talk about and say we can now do in space or will be doing in the near term.  Safety was discussed, including microgravity, radiation, plus a mention of unknowns regarding what we already know about gut bacteria exposed to radiation given our limited amount of research on this topic to date. A listener asked him about physics as a main reason for space exploration and contrasted that to settlement as the main reason for HSF. Another listener asked him about his mentioning USAF comments that indicated space was a mature and declining industry.  We began talking about commercial space, but we talked about it through the second segment as well.  In this segment, Dennis talked about how we have created economic growth in the past but now we have not only the challenge of economic growth but sustainable jobs and sustaining our standard of living.  Terraforming Mars was discussed as part of our discussion about Inspiration Mars and Mars One HSF missions to Mars.  As this segment ended, a listener asked him about suborbital space and citizen science projects.

In the second segment, John Hunt called in to talk about the high cost of many advanced space technologies, plus he wanted updates on LENR (this used to be called cold fusion).  Dr. Bushnell had much to say about LENR and it potential, we talked about Rossi, and the NASA work being done to better understand LENR effects. With an understanding of it, funding would not be as big a problem as it is today.  He also said LENR had the potential to be transmutational.  Our guest suggested that for more information, we visit the Larsen LENR slideshow:  www.slideshare.net/lewisglarsen/slideshows.  Again, he pointed to cultural issues as major stumbling blocks to this research.  In returning to the focus of his paper, he said there was no shortage of ideas but the culture was preventing them from being tried, tested, and exploited.  Rocket reusability was brought up, our guest mentioned the SpaceX Grasshopper work, and he was asked about SLS and fuel depots.  I asked about BLEO issues and radiation.  In response to another question, he said that were he the space guru, he would focus on “energy” and structural materials. You will want to hear this discussion. Later, Tim called from Huntsville about radiation and HSF to Mars, as well as the economics of the Big Dumb Booster.  I asked Dennis about the target audience for his paper and he said it was meant for NASA and the world since space fairing is a world endeavor. He again talked about potential revolutionary technologies which are needed and which would benefit all of us.  He repeated that we must do the difficult and take the risk and invest.  We also need to look forward with multiyear planning.  Near the end of the program, Dennis was asked about space elevators which he was not enthusiastic about.  Again, he repeated that we needed to make investments to raise our TRL levels.  At the end, I asked why space does not rise to importance in presidential campaigns & elections.  He said space was very good as an Earth utility but beyond that, there was no clear basis for most of it and that was the problem. Don’t miss his comments on this topic.  Our final topic was his assessment of commercial space given his years spent working on it with NASA including budgets into the hundreds of millions to find a way to close a commercial space business case for commercializing the ISS and other things.  This is a very important short discussion, don’t miss it.

Guest: Mark Sirangelo.  Topics:  Dream Chaser, hybrid rocket motors, human spaceflight & 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.  We welcomes Mark Sirangelo of Sierra Nevada Corp Space Systems to the program to discuss Dream Chaser, hybrid rocket motors, human spaceflight, space policy, budgets and more.  You can learn more about Dream Chaser at http://sncspace.com/space_exploration.php.  For those of you interested in learning more on the previous NASA HL-20 concept vehicle, visit www.nasa.gov/centers/langley/news/factsheets/HL-20.html.  We started our discussion by asking Mr. Sirangelo for a brief history and overview of Dream Chaser.  He talked about the lifting body design and the capabilities of a lifting body, including costs and reusability.  In response to questions he did say it was meant for LEO though later in the program he discussed the potential to scale Dream Chaser up if markets warranted it.  He was also asked to compare the Dream Chaser style of vehicle to a capsule.  Mark was asked about the choice of rocket, the Atlas V.  While he explained that choice, he also said Dream Chaser was rocket agnostic. Don’t miss his comments on the rocket question.  A listener asked him to clarify the current status with the SAA, the FAR, and a possible CCDEV 3 round of NASA support.  Mark said there would be a round three with a call for awards in February with winners announced later in the summer.  He talked about the companies going to the next level, the Critical Design Review (CDR) and what this means for NASA as well as the companies.  Mark talked about the switch back to the SAA but said at some point down the road, the FAR will likely be used, probably in the acquisition stage.  Again, you do not want to miss what he had to say on this important issue.  Yves from Canada asked about the launch abort system for Dream Chaser and its ability to land in places and the ocean instead of a designated runway.  We talked about test flights, the number of needed flights, and the view that testing is not based on the number of flights but on successfully completing the essential and needed testing/flight protocols.  In our second segment, Trent called from Australia and wanted to know more about the full history and struggles for Dream Chaser up to now.  This time around Mark provided us with a more comprehensive vehicle history.  We also talked quite a bit about the hybrid rocket motor so you will for sure want to hear this segment.  Mark was asked if the Dream Chaser hybrid was the same being used for the Virgin SS2 and he said essentially yes other than for size.  He was asked some more questions about his work on SS2 for Virgin but deferred those questions to Virgin .  Our guest received a few questions about the GAP, buying rides on the Soyuz, recent Soyuz issues, and speeding up the development of Dream Chaser.  Harry wanted to know about using Dream Chaser for various types of orbital space tourism, and much was said about certifying Dream Chaser as safe for human spaceflight.  Near the end, Robert wanted to know if Dream Chaser might be used for Point to Point travel.  John from Jersey City called to ask about multiple markets for Dream Chaser.  As our discussion was drawing to a close, our guest was asked about hypergolic fuels and reaction control systems and again about the thermal protection system.  Please post your comments/questions for Mark Sirangelo on The Space Show blog at the above URL.
