We welcomed Dr. Lewis Dartnell to discuss his book, “The Knowledge: How To Rebuild Civilization In The Aftermath Of A Cataclysm,” then applying it to starting up a space settlement regardless of where the settlement might be located. During our 68 minute discussion, Dr. Dartnell started out by giving us the background to his having written the book, some of the applicable constraints for the book, and that it was written for terrestrial events though there were ways to extrapolate some of it to space settlement issues. Dr. Dartnell explained what it would take to reboot civilization depending on why it was destroyed. He listed three possible sources of destruction. One was a viral epidemic or pandemic, another was nuclear war, and another was being hit by a large asteroid or something similar. He also said it might be easier to reboot after a pandemic because infrastructure would still be standing and largely available for use whereas with the other two, destruction would be overwhelming. We talked about skill sets needed to reboot, then we talked about the minimum size for a new community to start over. Here we extrapolated to space, exploring what it would take to start a space settlement. The initial numbers were high but not as high as what would be needed later on. The need for genetic diversity was also high. Several times he referred to needing more women than men for breeding to seed the new settlement, but without genetic diversity and in light of possible in-breeding to get the early numbers up, generations of humans might be born that were genetically weak and that could be a problem. Genetic diversity, needing more women than men, microgravity and radiation issues were just a few of the challenges for the new space settlement. Past the initial number to get the settlement going, to sustain it there would be a need for thousands in the community. You don’t want to miss this discussion as it was an eye opener. Don’t miss why he said he would rather start a new Earth settlement even after a horrific cataclysm than a Martian settlement. He said the Earth settlement would be far easier no matter what the challenges than the Mars settlement. Dr. Dartnell then talked about the possibility that someday an Earth-like exoplanet would be discovered so we compared starting a settlement there as opposed to Mars. To make this comparison, we zeroed out all issues relating to space transportation. You might be surprised by what Dr. Dartnell concluded. Later we compared a lunar settlement with the other two. Much of our discussion revolved around the fact that Earth was and is habitable and even after the horrific event, would remain habitable. Mars is not habitable nor is the Moon. That fact alone is a huge contributor to complexity and challenges. Listeners emailed and called to ask Dr. Dartnell questions ranging from the number of skilled people needed to start a space colony to having sperm banks in space for the genetic diversity required for the new settlement to how free floating habitats might be different in their requirements as compared to planetary settlements. Questions were asked about the problems resulting from human exposure to unfamiliar biology, human contamination of the planet, and the planet contaminating the humans. These were all interesting discussions so you definitely want to hear the full 68 minute program.

We welcomed Gerald Driggers to the program to discuss his theories about Mars settlement but his science fiction book series Earth-Mars Chronicles.  You can find out more about his work and books by visiting http://earth-mars.com.  During the first segment of our 100 minute program, Mr. Driggers talked about his early interest in space exploration, his early work in the industry & then his becoming a space age dropout as he described it.  He told us why he embarked on the Earth-Mars Chronicles series.  Listeners sent him email questions asking him why Mars was so important & why it should be the choice for human settlement off the planet.  Gerald responded to these early “why” questions.  A listener asked if he would do a one way mission to Mars. You might be surprised by his answer.  Next up was Mars One given Gerald was one of the early supporters of the organization.  Gerald had much to say about Mars One and the Mars One model for humans to Mars.  He also discussed other HSF to Mars Models but their was lots of listener interest in discussing Mars One with our guest.  Later, Gerald said we would need to be at the Technical Readiness Level 7 (TR7) to go to Mars, be it the private sector or with the government.  June emailed to ask about the minimum viable size for a Martian settlement,  including genetic screening.  Evon emailed about landing large payloads on Mars & how Gerald addressed that problem in his books.  Gerald  brought up the need for humanity to be off Earth in case Earth is destroyed so I asked him if we needed to be in a hurry to develop an off Earth presence on Mars.  Our guest suggested it would be a very long time in coming as there was no forcing function for HSF to Mars, nor is fundamental research being done regarding human survival on long duration spaceflight trips.  Doug called to ask about the economic justification for settlements on Mars & to ask if the Moon was not a better and more economic choice than Mars.

In the second segment, Kirk from Trinidad phoned in to ask about the online presence for Mars One.  We also asked him about space in Trinidad and if it was a hot topic or area of interest.  More emails came in & Christine wanted to know what was next for Gerald in Earth-Mars Chronicles.  Tony wanted to know if there was a spiritual component to HSF to Mars.  Our guest responded in the context of religions.  Judith’s note  inquired if one of greatest blockades to space exploration were the entertainment options today including video games, computers, & other forms of entertainment.

Please post your comments/questions on TSS blog above.  You can reach Gerald through his website or me.

Guest:  Bas Lansdorp.  Topics:  The Mars One program from a business, financial, engineering, technical, & human factors perspective for Martian settlement.  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 Bas Lansdorp, founder of Mars One to the program to tell us about the program and respond to a wide array of questions pertaining to the Mars One plan.  For more information, visit their website at www.mars-one.com.  Also, check out their FAQ at http://mars-one.com/en/faq-en. If you want to ask Bas & his team questions, use info@mars-one.com.  Dr. John Jurist joined us as co-host regarding many of the human factors, technical, and media financing discussion topics.  Since our topic addressed many of the same issues with crossover for both segments, I have summarized the program without regard to segments.  We started by asking Bas about the Curiosity landing per the European media and the interest in Holland which is his home.  It was clear that Curiosity fever was strong and exciting across the pond just as it was here.  I then asked Bas to tell us about Mars One.  For the next half hour, Bas talked with us about why he started Mars One, plus he went over in some detail the Mars One plan, including financing, technical, engineering, human factors, and research issues.  After our introduction to Mars One, Dr. Jurist and I began asking questions about the Mars One media financing plan, human factors, micro and partial gravity issues, life support issues, and more.  We covered a broad range of issues including launches, launch state liability, family settlement on Mars, children on Mars, pregnancy, before the launch medical procedures, astronaut selection, etc.  We received several listener emails which we discussed with Bas throughout our 90 minute discussion.  After our initial introduction to the Mars One program, our discussion revolved around Bas responding to our questions and those asked by our listeners.  Some other issues discussed included time line, mission delays, the loss of a resupply mission & its impact on the overall Mars One timeline, RX medications on Mars, solar power as compared to nuclear power for Mars One missions, Mars EDL plans for both cargo and humans, outsourcing components for Mars One and payload integration services & needs, plus settlement sustainability issues with possible timelines.

Please tell us what you think by posting comments and questions on The Space Show blog.  For specific questions for Bas or his team, use the Mars One email address but also do post on the blog for the benefit of all listeners.

Guest:  Chris Carberry.  Topics: Explore Mars programs, space policy & presidential campaigns, HSF to Mars.  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 Chris Carberry back to the show to update us on new Explore Mars programs and also to talk about space policy & issues as part of a presidential campaign. You can follow along on their website, www.exploremars.org.  In our first segment, Chris started out talking about the Curiosity rover on Mars and its impact on policy and programming back here on Earth.  He also told us about a website created by Explore Mars, www.getcurious.com.  This additional site focused on Curiosity, but also as you will hear, described their Mars boulder program, what happened and where the thousand pound boulders went after Curiosity landed.  During this segment, we had a lengthy discussion about space as a political priority in presidential campaigns and Chris told us why in his experience space policy does not typically enter a presidential campaign.  Later we both said that the biggest issue facing our space program and HSF to Mars is the lack of political will.  Chris went on to tell us about their upcoming Space Blitz on Capitol Hill on Sept. 12, 2012, a joint program and effort with the NSS.  Chris concluded the first segment by telling us about an Explore Mars upcoming conference on Mars education scheduled for May 6-8, 2013.

In the second segment, a listener asked Chris why Explore Mars targeted women in its programming. Don’t miss the explanation offered by Mr. Carberry.  By the way, as far as I know, Explore Mars is one of only a few, maybe the only organization, that does programming specifically for women in space and for Mars activities.  Chris returned to Mars and space policy in political campaigns as well as political agendas, both in Congress and among the nation’s general population.  Since Chris is from Massachusetts, he got a few questions asking about congressional races in the state and the space policy/positions of the candidates competing for house and senate seats.  Chris was unsure of the various space/Mars candidate positions but noted that neither space or Mars had been or would likely be a discussion topic in anyone’s campaign this year.  I then asked Chris if he could design a space policy for a political candidate and he said yes though he would have to be very careful about how the policy was put forth and debated.  Don’t miss this discussion! I did encourage him to create such a campaign and post it on a blog or website for general information available to any candidate of any party who actually is interested in space or Mars.  Later in the segment, we talked about the importance of a Mars sample return mission, the potential for the private sector to fund an HSF program to Mars, and what he thought the Mars program in particular would look like in five years.  As the show was ending, he was asked about a Martian moon mission to either Phobos or Deimos.  In his concluding comments, he mentioned the upcoming 50th anniversary of our leaving the Moon and not returning.  He said we can certainly do better than that.

Please post your comments/questions on the blog.  You can email Chris through the Explore Mars website.
