We welcomed Dr. Erik Seedhouse back to the show for a variety of timely discussion topics. During the first segment of our 1 hour 37 minute program, Erik started out making comparisons with past polar exploration and going to Mars. He also said that going to Mars anytime in the foreseeable future would be a survival trip. We talked about Erik’s books on Virgin Galactic, Polar Exploration and Mars which will soon be released, and additional books on Dragon, Mars One, Mars via the Moon, and XCOR, all to be released over the coming months. Erik then spoke about his ISDC talk re comparing polar exploration to going to Mars and commented on the speaker following him, Dr. Logan (he was not sure of the first name but we think it was our friend, Dr. Jim Logan). He talked about radiation shielding and water per what Dr. Logan had to say including the need for 10 meters of water shielding to equal the protection here on Earth. Erik had much to say about radiation and shielding which prompted multiple emails from Dr. Doug in S. California seeking clarification and adding to Erik’s comments. I read all of Doug’s radiation themed emails throughout the first and second segment of today’s program. Don’t miss Erik’s conclusions regarding the radiation risks and shielding needs for a Mars mission, how astronauts would live and work on Mars as well as the Moon. Erik next talked about Virgin Galactic and XCOR saying he thought XCOR would be the first to fly commercially. When asked about the biggest passenger risk on a suborbital flight, Erik said it would be the cardio-vascular risks. Erik got questions regarding SpaceX, Elon Musk, and the Mars Colonial Transporter. He again stressed the way to go to Mars was via the Moon and that would be his preferred space policy. He also put forth his Mars simulation study plan. Don’t miss it, I think it’s a good one.

In the second segment, John from Florida called to comment on delays and how long commercial suborbital flight was taking since the success of Spaceship 1. John seemed to compare the lack of progress with suborbital flight to how much progress was made with aviation and in particular jet travel. I took the first pass at responding to him, then Erik offered his comments. What do you think? Let us know on the blog. Erik was then asked about other human factor issues than radiation. Dr. Seedhouse went through a laundry list of health risks and concerns for astronauts in deep space and on long duration spaceflight. He was then asked about the regulatory regime for suborbital space, then he wanted to define space given Virgin Galactic may not flight beyond 50km which is not space. Don’t miss what he had to say about this and the overall health risks for astronauts in deep space. Near the end of the show, Erik addressed space settlement. He said it would be a natural expansion and would happen automatically with returning to the Moon and going to Mars via the Moon. In his concluding comments, he suggested that advocates and space enthusiasts need to adjust expectations and understand the technology involved because its harder and more costly to do things in space, including suborbital space, than originally thought and expected.

We welcomed Dr. Erik Seedhouse back to the show for this 1 hour 28 minute discussion regarding suborbital space and Erik’s new book, “Suborbital: Industry at the Edge of Space.”  In the first segment, Erik started out by telling why he wrote the book and he gave us updates regarding the prominent suborbital space companies.  We talked about payload flights, science flights, academic flights and space tourism flights.  Dr. Seedhouse spoke to the need to lower the cost for the flights and the need to prepare for painful accidents.  Listeners asked him to describe the flight profile for SpaceShip2 and the training many of the passengers had taken at the NASTAR Center.  Erik then spoke about competing centers, the American Astronautic Institute in Florida and Waypoint 2 Space which is adjacent to NASA JSC.  Questions came up about Astronauts4Hire and & the need to self market to get a flight.  Erik talked about floating free during the microgravity part of the flight on Virgin, addressing the issue of getting back to your seat on time before reentry.   Near the end of the segment, a listener asked why it was taking so long for suborbital flight we it was done decades ago and the information is in the public domain.  Ham the Chimp got mentioned in this section.  As the segment was closing, the new topic of space motion sickness came up.

In the second segment, a listener wanted to know if it mattered to the passenger re medical issues if vertical launch was used or horizontal launch was used.  Erik said the g force was the biggest medical problem with suborbital space.  He also talked about long arm centrifuge training, then he went over the Anti-G Straining Maneuver to deal with g force issues.  Space suits came, space tourist physical conditioning was discussion topic as was space radiation which Erik said was not a problem for suborbital flights.

Please post your comments on The Space Show blog above. Erik can be contacted at DrEricSeedhouse@hotmail.com.  Erik’s website is www.suborbitaltraining.com.

We welcomed back Dr. Erik Seedhouse for this 1 hour 34 minute discussion of his new book, “SpaceX: Making Commercial Spaceflight A Reality.”  During the first segment, Dr. Seedhouse talked in general about the book, the fact that it addresses other commercial space companies and the suborbital field as well as SpaceX, plus Mars missions, funding, investment, and government support through COTS, Commercial Crew and other programs.  In fact, he said that 80-90% of funding for commercial launch companies was government funded at this time.  When asked if this suggested something other than a commercial company, he said no.  Lots of listeners both emailed and called in with questions about SpaceX and their projects.  One listener wanted to know if Dr. Seedhouse thought SpaceX might be spread too thin with so many projects.  Another wanted to know about meeting launch timelines and slippage, while another wanted to know about the new version of Falcon 9 about to be launched.  There were lots of questions and much discussion around the Falcon Heavy and the SpaceX manifest per their website.  Erik talked about ULA as a major SpaceX competitor and Doug called in wanting to know if Erik thought Falcon Heavy might actually be too much rocket for the market at this time.  He also inquired about the potential Falcon Heavy impact on human spaceflight.

In the second segment, Mars One, Inspiration Mars, and Dream Chaser came up for discussion.  Dr. Seedhouse talked about SpaceX and Mars but he also stressed the need for resolving EDL problem regarding future large payload missions to Mars.  Another listener wanted to know if Falcon Heavy or even the Falcon 9 could launch the Orion and then Doug emailed in and then called to ask about the SpaceX Mars Colonial Transporter.  Several times in both segments, Dr. Seedhouse stressed that his book was upbeat and written as a devoted fan of SpaceX accounting for the company’s first ten years.  He also said that he had no support nor did he have any interviews with anyone from SpaceX regarding the book.  Toward the end, Jacob sent in an email asking our guest why some in Congress still seemed opposed to commercial space, SpaceX and others.  Erik made it clear he did not include politics in his book but he suggested that Congress does tend to work toward reelection, often over the national interest.  Of course defining the national interest may not be as objective as we would like so it’s a tough question to answer, for sure.  The last listener question asked Erik if there was a commercial space effort of any significance coming from any other country.  Erik’s simple answer was no but you will want to hear what he said in response to this question.

Please post your comments/questions on The Space Show.  If you want to contact Dr. Seedhouse, you can do so through me.

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 Dr. Erik Seedhouse back to discuss his latest book, “Pulling G: Human Responses to High and Low Gravity.  I strongly recommend this book as it is a terrific resource on the subject of G-force on the human body.  If you buy it using this URL from Amazon, Amazon will make a contribution to The Space Show:  http://www.amazon.com/Pulling-Responses-Gravity-Springer-Popular/dp/1461430291/ref=onegiantlea20.  Our 1 hour 42 minute discussion was in two segments but as our topics overlapped segments, there will be no part one and part two for today’s program summary.  Dr. Seedhouse began the discussion talking about the different types and sources of gravity on the human body.  This included acceleration, lateral, reentry, vibrational, and more. We talked about helmet restraint issues, Formula One race cars and taking corners at high speed producing a high lateral G force, jet fighters, rocket flight, roller coasters, and more.  Erik went over the proposed flight profile in g terms for Virgin Galactic and other proposed vehicles.  He also talked about centrifuge research and findings with the general public at the NASTAR facility.  He then switched to g-load force, fighter pilots and the Anti-G straining maneuver and breathing that they do to help counter excessive g’s.  Suborbital flight came up and here, Dr. Seedhouse had much to say given the small amount of suborbital human spaceflight history.  We also talked about bone loss and density issues, osteoporosis, and obesity.  Erik said the best physical profile for resisting high g force was short and stocky.  The worst was tall and thin.  Don’t miss his explanation for this. He also said smokers do better in high g’s over nonsmokers.  Erik got lots of question about the Bill Weaver SR-71 ejection.  Then he mentioned the Armstrong Line and said above that point, blood boils without a pressure suit. Erik also talked about orthostatic intolerance (OI) in the context of g tolerance.  He talked about professional astronaut training for suborbital missions such as with Astronauts4Hire.  We then discussed the financial problems hitting the Canadian aerospace industry with layoffs, closures, and the possible sale of valuable space hardware.  Listeners wanted to know about anti g countermeasures, if any, and laser eye surgery was discussed although Erik said it was no longer a problem.

Contact Dr. Livingston for questions about our copyright and trademark policies.  We welcomed Dr. Erik Seedhouse back to the program to discuss his new book, “Astronauts For Hire: The Emergence of a Commercial Astronaut Corps.” You can order the book from the following link & when you do, Amazon makes a contribution to The Space Show/OGLF:  www.amazon.com/Astronauts-For-Hire-Commercial-Exploration/dp/146140519X/ref=onegiantlea20. While our program was in two segments, again, our topics crossed segments so this summary is written without regard to segments.  Dr. Seedhouse introduced us to the organization, Astronauts4Hire.org which is also their website.  On their home page, you can subscribe to their newsletter and news alerts for the organization as they strive to build a commercial astronaut corps. Erik told us how to join up, the difference with Flight Members and Associate Members, what the flight qualifications consist of, and how they envision their role in flying citizen science experiments on the upcoming suborbital flights.  While we did mention orbital flights, Erik said the difference was significant with suborbital and for now the focus was completely on suborbital.  As you will hear, the book is much broader than the organization as he goes into many of the human factors impacting HSF, both on the suborbital level and the orbital level.  His book addresses the leading companies in the industry, NASTAR training for suborbital astronauts, and forward looking potential commercial space businesses.  One of the issues that can negatively impact suborbital human flight is space sickness and Erik spoke about this in some detail.  He also talked centrifuge training and G-forces on launch as well as the reentry. Near the end of the program, we talked about suborbital vehicle safety, launch abort, and crew escape.

Guest:  Dr. Erik Seedhouse.  Topics: Ocean outposts, living underwater, and the oceans as an analog to space.  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. Dr. Erik Seedhouse returned to discuss his book “Outpost: The Future of Humans Living Underwater.  If you buy the book from Amazon with this URL, Amazon will contribute to The Space Show: www.amazon.com/Ocean-Outpost-Underwater-Springer-Popular/dp/1441963561/ref=onegiantlea20. In our first segment, Dr. Seedhouse introduced us to the subject of living underwater.  We discussed some of the basics per the outline suggested by the contents in his book.  You can see the book’s contents at www.amazon.com/Ocean-Outpost-Underwater-Springer-Popular/dp/1441963561/ref=onegiantlea20#reader_1441963561. Follow along for the general topic discussion. He received questions about comparing living underwater to living in space or perhaps on the Moon or Mars.  I asked our guest about human factors issues such as those experienced in long duration spaceflight.  Dr. Seedhouse talked about bone necrosis with the saturation divers.  Other issues in this segment dealt with scuba as a pre-requisite for spaceflight training, the recent deep dive in a small submarine by James Cameron, and the amount of money spent on ocean habitat R&D compared to that being spent in space.
      In our second segment, we went into detail on many of the topics in his book including biochemical decompression, liquid breathing, vasculoid, and artificial gills.  We compared space suits to dive suits, specifically the ADS2000 hard suit.  Several listeners called in asking about time lines for operational ocean outposts and habitats as well as many of the advanced technologies Dr. Seedhouse was telling us about.  Near the end of the program, our guest went into more detail about budgets for developing the capacity to live underwater as compared to the NASA budget and what the private space sector is now doing.  Erik also compared the amount of press, media , & PR given to space matters as related to ocean matters.

Guest:  Dr. Erik Seedhouse.  Topics:  We discussed his book, “Interplanetary Outpost: The Human and Technological Challenges of Exploring the Outer Planets,” the human factors issues & the technical issues for such missions.  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 Dr. Seedhouse to discuss his new book on interplanetary missions.  Remember, if you buy the book using the following Amazon URL, Amazon will make a contribution to The Space Show/OGLF (www.amazon.com/Interplanetary-Outpost-Technological-Challenges-Exploration/dp/1441997474/ref=onegiantlea20).  Dr. Seedhouse began our discussion by talking about the interplanetary mission research that has been done over the years and is still continuing though in a greatly reduced mode.  In this discussion, he referenced the HOPE Study for mission architecture to travel to Callisto, one of the moon’s of Jupiter.  He also talked about research going on with ESA regarding human hibernation and on this subject, we spend a considerable amount of time. Artificial gravity and radiation were discussed along with vision problems for astronauts having spent at least four months on orbit.

As we started the second segment,Marshall called in and wanted to know about athletic and sports games to pass the time for the crew on long spaceflights.  Dr. Seedhouse thought more of the idea to have some sort of sport or athletic game at the destination rather than on the spaceflight.  We also talked about what it would take to change attitudes and policy to undertake an interplanetary mission.  At one point in the discussion, our guest suggested we might be too soft in modern times to explore and that we were no longer as interested in exploring as we once were.  Make sure you hear this entire conversation.  We fielded more listener questions and calls, talked about humans being able to adapt to the space environment over a long period of time and genetic screening for crew selection.  We covered crew selection in some detail which then took us to the subject of bioethics which do not yet exist in any formal way for an interplanetary mission. Erik did include his version of an Interplanetary Bioethics Manual as Appendix II. We talked about pregnancy, pre-emptive surgery, death of a crew member, death of a family member back on Earth, waivers that would need to be signed by both crew and family members, and much more.  Toward the end of the program, our guest was asked about interplanetary propulsion systems and multigenerational crews.  Erik talked about the VASIMR and we asked lots of questions about the 2nd and 3rd generation members of the multigenerational crew and how to be sure they become doctors, engineers, and other positions needed for the crew’s survival and success.  We also talked about modernizing space suits and Erik told us about Blue Suit Days as a requirement for Canadian astronauts for space outreach support.
