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.

Welcome to this two hour open line discussion covering a wide range of space topics.  During the first segment which was half an hour, I introduced the program and some possible topics, plus I spoke about having attended AIAA Space 2014, the SmallSat 2014 Conference which was held the same time as AIAA, and I referred back to my having also been at the NewSpace 2014 conference.  Some possible topics of interest for discussion included a recent news story about astronauts usage of sleeping pills while on orbit.  Nobody seemed interested in that topic as it was not discussed during this program.  I also noted the huge gap between those working SLS or having an interest in it and those on the side that hate it and think it’s a huge waste.  As I said, the gap was wider than the Grand Canyon with no signs of narrowing.  This issue was raised during the second segment of tonight’s program.  You can read Duane’s article on the lessons learned astronaut panel I mentioned on air at http://www.aiaa-space.org/Forum.aspx?id=24589.

We paused for a short break and we opened the second segment with a call from John in Ft. Worth.  John remained on the phone for quite some time and we covered lots of topics.  Initially, SLS John, as I like to refer to him, went over his SLS place holder theory again.  We did spend lots of time talking about SLS, the gap between supporters and haters of the project, its operational plan, congress, and more.  We also talked Falcon Heavy which John suggested was potentially less real than SLS though I countered that thought.  We talked about the RD-180 rocket motor problem, and I told him & the listeners about some of my AIAA discussions, interviews including my breakfast with Dr. Mike Griffin & Frank Van Rensselear of Schafer Corp.  We also talked Dream Chaser and the press conference SNV held at AIAA, plus I talked about my interview with Larry Price, Deputy Director of Orion.  John said his real interest in space was advanced propulsion, specifically nuclear. Somehow our conversation ended up talking about Area 51 and the Clinton era lawsuit against the government by workers exposed to toxic materials.  As soon as John got off the phone, Dwayne called in.  He clarified the Area 51 story for us as well as the old litigation that the workers won but then Pres. Clinton used an Executive Order to overturn the court decision.  Dwayne also spoke about 3D printing in space and the recently concluded NRC 3D Printing In Space(http://www.nap.edu/download.php?record_id=18871  note you may need to open a free account to download the report for free).  There are also lots of news stories about the report should you care to research it.  We talked about 3D printing in space, how it might be used, and the possibility of a later metal printer in space.  Dwayne then spoke to the old Coke and Pepsi wars in space several years ago and he addressed the gap with SLS supporters and those that are against it.  He said it was a huge gulf and that he thought both sides may have less than a firm grip on reality regarding SLS.  In addition to the two calls, we fielded an email from Doug who brought up space settlement, the value of attending space conferences, and the commercial crew down select process.  Tim was our last caller and he brought up SLS again, we talked about the congressional candidate on the independent side in the Huntsville district, Mark Bray in that Mark works on the SLS project and that it would be interesting to know his space policy views since he might win the congressional election.  Tim also mentioned a article about Elon Musk in the NextBigFuture.com re an eighty thousand person Mars City by 2040.  You can download the article at http://nextbigfuture.com/2014/08/elon-musk-timeline-and-extrapolation-of.html.  The final email was from Joe in Houston wanting to know the NASA down select process & who might be responsible for it.  I could not answer his question but please, if any listeners know the answer, post it on the blog.

As always, please post your comments/questions on TSS blog above.  You can reach any of the email listeners or the callers through me.

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.
