We welcomed back Dennis Wingo for this 93 minute discussion. PLEASE NOTE THAT WE ARE NOW CONDUCTING OUR ANNUAL FUND RAISING DRIVE.  WE NEED YOUR SUPPORT FOR THE SPACE SHOW AND ITS PROGRAMMING EFFORT.  During our first segment, Dennis talked about his recent blog article at http://denniswingo.wordpress.com, To ARM or Not To ARM: Is That Really Our Question.  I urge you to download and read this article as Dennis refers to it many times over during our discussion.  He started out with an analysis of what was thought to be the NASA ARM mission as compared to what it has become today.  As you will hear, he was supportive of the initial mission, not the current evolved mission.  He explained why the shift in his position which was based on making the ARM mission a minimalist type mission.  He explained the differences in detail.  Budget reasons were cited as a primary reason for the mission being downgraded.  Dennis offered us an historical analysis & perspective of the NASA budget.  SLS, Falcon Heavy, & lots of space policy made it to this segment.  Dennis talked about solar electric propulsion for ARM, then he was asked about the likelihood of the next president initiating an RTM program.  Doug emailed about a COTS like program with ULA & Masten for a lunar lander.  Dennis had much to say about a lunar lander dating back to the Gemini era up to new, lower cost ideas coming from the commercial space industry.

In the second segment, Dennis continued talking about the upcoming new Congress and what might emerge as a different type program with a different budget though he thought we were more likely to entertain the status quo.  Several listeners wanted to know if it would boil down to the Moon vs. ARM or the Moon vs. Mars.  Don’t miss his response to these questions.  Our guest suggested we all watch the “Wanderers” video which you can see at http://vimeo.com/108650530.  Dennis mentioned that we did not need a government program as such for space but he did speak in favor of public/private partnerships.  We spoke much about the need for space and lunar infrastructure.  Sally asked him to explain the difference with the economic development of the solar system and space settlement.  He said space settlement was very much a part of a space economic development effort.  In response to another set of listener questions, Dennis talked about the 90-10 rule when has about robots in space as compared to astronauts.  Doug called to talk about investment capital for commercial space plus other issues.  I then asked Dennis if Lunar Cots or industrialization was included in solar system economic development and if so, at what stage?  Kirk emailed in a question challenging the role played by offering prizes.  Don’t miss what Dennis had to say in response to Kirk’s email.  Before we ended the program, Dennis mentioned his latest blog article about Apollo betrayed by the very people who made the Apollo mission happen.  You can read this article at http://denniswingo.wordpress.com.

We welcomed author Frank White back to the show to discuss the 3rd edition of “The Overview Effect” and a philosophy of space exploration.  Special pricing is available for the book at http://arc.aiaa.org/page/25for25sale.  During the first segment of our 93 minute program, Frank said that he had interviewed 29 astronauts plus three future astronauts.  He then talked about new interviews for the newly released 3rd edition of the book, highlighting interviews with Helen Sharman in the UK, Sandy Magnus, Akihiko Hoshide, Sir Richard Branson, George Whitesides & Loretta Hidalgo Whitesides among others.  He also spoke about his interview with Loren Acton.  One of the significant differences from the earlier editions was the focus on the New Astronauts.  One theme that was repeated during the show was based on the interview with Dr. Sandy Magnus and her comments about their being a difference in understanding the overview effect intellectually as compared to experiencing it.  This opened the door to listener emails about the type of communication among people who have experienced the overview effect with those who have not experienced it.  Later in the segment, Frank mentioned there was no philosophy of space exploration, suggesting that the overview effect might be able to create such a philosophy.  As the segment was ending, Marshall called to ask about gender differences as well as differences among engineers & those with other backgrounds.

In the second segment, we heard from Joey in the UK about the overview effect with Chinese and Russian taikonauts and cosmonauts.  Carl sent in a note to challenge the peace and harmony picture being presented by bringing up  today’s reality with a focus on those wanting to destroy others.  He did not think such groups would be particularly open to transitioning from their ideology to one supported by the overview effect.  Don’t miss Frank’s response to Carl.  Frank took a few minutes to talk about his Kindle book, “The New Camelot.”  The book looks into the King Arthur and Knights of the Roundtable story, suggesting that President Kennedy was Arthur sending out astronauts on a quest.  Like Arthur, JFK was hoping to unify the realm (so to speak).  This topic came up later in this segment in more detail.  We did talk about human spaceflight and global advocacy, commercial spaceflight, & the benefits of simulation for getting people to “get it” about the overview effect.  Listeners emailed Frank asking if overview effect training was being included in the many personal spaceflight training programs now available on the market.  Near the end, Frank talked about a possible 4th edition of his classic book.

We welcomed Bruce Pittman back to the show to discuss the emerging commercial space industry. During the first segment of our 90 minute program Bruce said this was the most exciting time every for commercial space, certain in his 30 plus year career.  He talked about there being a paradigm shift underway, NASA challenges and the progress made in just five short years.  He cited examples with COTS, commercial payloads to the ISS, SpaceX, and lots of smaller companies working with small satellites.  Other examples included the 3D printer on the ISS, the growth of spaceports, the industry spreading out into multiple states, and investment capital coming to the industry.  I asked about human spaceflight (HSF) and he said it was more challenging and demanding but was optimistic that launch costs would come down, especially if reusability enters the market.  Reusability would greatly assist in bringing more commercial options to the table even for HSF.  Jerome in the UK emailed to ask about a commercial space industry outside the U.S.  Both Bruce and I commented on Jerome’s question.  Harry emailed Bruce to inquire if going public was essential for pushing the emerging commercial space industry forward.  Bruce was also asked what excited him the most in the industry.  Listen to his choices. I asked our guest if he saw SLS as an asset to the emerging commercial space industry, being neutral, or being a detriment.  He believes there will be synergistic enhancements for both SLS and the commercial space industry through the development of SLS.  Don’t miss his full comments. Bruce was asked about commercial space ventures being able to finally close a business case and having more than just government as the customer.  Allison emailed us asking Bruce to define paradigm shift.  This also proved an interesting discussion.  Near the end of the segment, our guest was asked bout NEOs and commercial opportunities.  We also talked about two NASA papers in this segment.  The first, “Pioneering Space: NASA’s Next Steps on the Path to Mars” from May 29, 2014 can be downloaded at http://www.nasa.gov/sites/default/files/files/Pioneering-space-final-052914b.pdf.  The second paper, “Emerging Space:  The Evolving Landscape of 21st Century American Spaceflight,” can be downloaded at http://www.nasa.gov/sites/default/files/files/Emerging_Space_Report.pdf.  Just before the break, Paul asked about fuel depots for the commercial space industry.

In our second segment, we started talking about space settlement, pioneering, and space exploration.  Bruce explained the differences with pioneering making it possible to have a permanent presence in space by getting in place needed infrastructure and the basics for living in space.  Space settlement would be established after pioneering.  Exploring goes forth to find out what is out there and to return to tell about it.  A listener asked if going to the Moon was a pioneering step on the way to Martian settlement.  Later, Bruce said that pioneering will be driven by economics. In this segment, we also talked about property rights and benefit sharing plus the impact these two issues might have on the emerging commercial space industry.  Risk averseness came up as well.  As we were drawing to a close, Bruce mentioned how all of the industry was in a transitional period, including traditional aerospace.  He suggested things to look for over the coming months included more commercial activities on the ISS, the upcoming Bigelow module for the ISS, & the Google Lunar XPrize.  In closing, we talked about Silicon Valley and the industry as well as the lowering of barriers to entry for emerging commercial space companies.  Bruce also mentioned the Next Giant Leap Conference in Hawaii, Nov. 9-13, 2014.  For more information, see http://2014giantleap.aerospacehawaii.info.

Welcome to this 2.5 hour Space Show Classroom discussion with Dan Adamo, Dr. John Jurist, & Dr. Jim Logan regarding the recently released NRC “Pathways To Exploration: Rationales And Approaches For A U.S. Program Of Human Space Exploration.”  You can download the report for free at  http://www.nap.edu/catalog.php?record_id=18801.  In addition, the project referred to in the last part of this discussion by Dan and Jim, the “Aquarius interplanetary HSF transport” paper can be freely downloaded at  http://www.spaceenterpriseinstitute.org/2014/07/aquarius-a-reusable-water-based-interplanetary-human-spaceflight-transport.  Please note that our panel members used cell phones which caused audio issues which you may hear during the discussion.  Finally, as this program will also be archived on both The Space Show and The Space Show Classroom blogs, there will be two papers uploaded to each blog, one by Dan Adamo & the other by caller Dr. James Dewar. I will mention both in the summary below.  In the first segment, our panel members opened with their perspective on the NRC Pathways HSF study.  While there were similarities in their perspectives, there were also noteworthy differences.  After this comprehensive introduction, I asked our panel members about the study and space settlement or pioneering.  Each panel member had much to say on the settlement issue, including the need to solve the gravity prescription for long duration HSF or settlement.  Our panel members  said that for the most part, space settlement was out of scope for this report.  In this part of the discussion much was said about microgravity issues & the need to do on orbit experiments to determine the HSF gravity prescription.  Deimos was discussed as an initial better choice that the surface of Mars re microgravity issues.  Our guests spoke to the need of a short arm centrifuge on the ISS.  Jim spoke to the specifics of such an experiment such as 1 G at the head., 2.5 g’s at the feet for two hours a day to see how it serves as a microgravity countermeasure.  Our panel members mentioned that there already was such a short arm centrifuge built years ago by NASA and Wiley, http://www.nasa.gov/centers/johnson/slsd/about/divisions/hacd/laboratories/short-arm_centrifuge_laboratory.html.  The guests talked about unknown human factor challenges for going to Mars and long duration spaceflight.  Jim provided us with interesting statistics on human spaceflight totals since the beginning in 1961.  The panel members had much to say about the budget issues discussed in the NRC study.  Another point brought up was the study’s assumption that if we are not going to the surface of Mars, why even do HSF?  Near the end of the first segment, listener Carl brought up the well known plans for Mars settlement with Elon Musk & SpaceX.  This sparked quite the discussion so don’t miss it.

In the second segment, our panel talked about the value of the Pathways study, international partnerships and what they saw as contradictory statements, especially regarding the mission cost impact of such partnerships.  John mentioned the study’s reference to NASA education & public outreach which he thought was more focused on STEM & the development of more engineers rather than on educating the general public to be more knowledgeable about science.  The panel members  noted that there was little attention paid to the societal impact of not even having a human spaceflight program.  Dan & Jim agreed on the importance of educational outreach and shared their experiences with us from the employment with NASA.  Adrian in San Diego sent in an email suggesting the panel was being pessimistic and that China would not overthink issues and just do missions without full disclosure.  All three panel members had much to say in response to Adrian’s charge of being pessimistic.  They talked about being reality based, not pessimistic & why it was so important to be reality based.  The panel hit back hard on the charge of being pessimistic.  Dan & Jim said to be other than realistic was reckless and irresponsible.  Jim also said that being called pessimistic suggested to him that reality had violated the person’s ideology.  Jim would be happy to debate the issues with anyone in open forum.  This discussion brought Jim and Dan to talking about their Aquarius project which you can download at the above URL.  They spent some time discussing the benefits of their approach, noting how it addresses & mitigates many of the problems associated with a HSF mission to Mars.  They also spoke to the need for nuclear propulsion and talked about using water as fuel and very high ISP ratings with high temperatures.  During this discussion, Dr. Jim Dewar called in to suggest their ISP ratings were low, he explained why, and he talked about starting small to start flying and then improving as you go.  We did not know it but we lost John from the connection but Jim, Dan, and Dr. Dewar spoke to the NERVA project, and specifics about nuclear propulsion.  This advanced nuclear propulsion discussion was close to a half an hour near the end of the program.  Dr. Dewar was a guest on the program in 2008 & 2009 regarding nuclear propulsion & its history. He also authored two books on the subject.  Use the GuestSearch tool on our website to find his interviews which I suggest you listen to if you have not already done so.  I will also upload to both blogs the paper Dr. Dewar referenced in his discussion.  After the nuclear discussion, Adrian sent in another email titled “rebuttal.”  He challenged the panel members to do the experiments, not just to talk about them.  Jim, Dan & I challenged Adrian for his solutions to doing many of the needed & essential experiments. All of the panel members supported doing the needed experiments & have said so for decades.  Getting funding for the experiments, NASA approval, etc. is a challenge.  I then challenged Adrian to come to The Space Show as a guest with his solutions for doing the essential work & experiments rather than his just talking about how badly they are needed per his second email.  I hope Adrian does have answers and will contact me about coming on the show to discuss them with us.  Jim & Dan each provided closing comments focusing back on the study report.  They thought the report was worth it from the taxpayer perspective and that it would be used for references.  Jim did think the report was not as good as other government studies he had seen because it was so speculative, something all three guests addressed in their opening remarks.  An 11th hour call came from SLS John to talk about the ISP formula & temperatures Dan and Jim used in their paper Aquarius paper.  Dan authorized me to upload to the blog his written comments on the NRC Pathways study so you will find that document on both blogs as well.

Please post comments/questions on The Space Show blog.  You can reach the panel members through me.

We welcomed former NASA astronaut Leland Melvin to the program to discuss Spaceship Earth Grants (SEG) (www.spaceshipearthgrants.com) as Leland is the president of the organization.  This program was a one hour show so there was no break as we had just one segment.  Mr. Melvin started out by telling us about SEG which he said was formed to do good in the world.  He talked about their contest for raising money to send people to space so that they will experience an orbital shift in perception (The Overview Effect) and upon return, do work and good with this new perspective of Earth.  They want this new perspective shared with others for the benefit of all.  He talked about the application for the contest and the fee structure which you will find fully explained on their website so see the above URL.  Leland explained that this was a crowd funding program though not like others that use specific crowd funding program such as Kickstarter or Indiegogo.  We also learned from a listener question that the contest winners will choose their own carrier for going to space and will need to comply with the rules & conditions set by that particular carrier.  Later, he mentioned that they would have a spaceflight training academy but details would not be announced until later in October.  The contest involves paying a fee which is on a sliding scale, submitting a video and writing an essay on why you want to go space.  I asked our guest why the average person needs to go to space.  Leland spent some time responding to this question so don’t miss this crucial discussion.  Leland was asked if students on a global bases seemed interested & inspired by space when he spoke to them.  He said yes & told us a great story about what happened with a Brooklyn student who slept through his talk.  We talked about international space cooperation, specifically with the Russians even when our non-space relationship with Russia was at a low point.  Regarding their contest, Leland talked about some of the benefits early adopters get by filling out an application, submitting the video, essay, and fee.  A listener asked if they would market their space flights for adventure as do the space tourism companies or are they only going after the change in perspective & Overview Effect benefits.  I asked Leland if he had experienced the Overview Effect on his two Atlantis flights. The same question was asked about his astronaut peers.  Leland had much to say in response to this question because when he went to space, he was not familiar with the Overview Effect but told us that what he experienced was the Overview Effect without putting a name to it.  Later in the program, we discussed SEG being founded on the principles of Muhammad Yunis, then Leland was asked by Kristin if SEG would focus on space settlement as well as tourism.  We learned that the organization was accepting applications from 156 countries.  In his summary, our guest talked about civilizations coming together through space, the orbital shift in perspective by just being in space, and the need to fund STEM programs/students.

We welcomed Dr. Mark Shelhamer, Chief Scientist of the NASA Human Research Program to the show to discuss the critical risks associated with BLEO long duration HSP. You can hear his FISO talk on this topic from April 2, 2014 at http://spirit.as.utexas.edu/~fiso/telecon/Shelhamer_4-2-14/Shelhamer.mp3.  His associated Power Point can be downloaded at http://spirit.as.utexas.edu/~fiso/telecon/Shelhamer_4-2-14/Shelhamer_4-2-14.ppt.  During the first segment of our 95 minute discussion, Dr. Shelhamer started off saying  we would be talking about beyond low earth orbit only and that many of the risks are unknown since we have very little experience with BLEO.  Much of what we do know is extrapolated from our current knowledge base plus our Apollo experience.  Next, our guest defined three major areas/issues.  First he listed medical issues which he later described as onsite medical treatments for various complications, illnesses, surgical needs and such.  He classified physical deconditioning issues such as muscle and bone loss issues, cardio vascular issues in a different category.  The second group he identified had to do with radiation, and the third group included psychological-social issues.  I asked about Microgravity not being in the top three and he said because those issues are likely a constant for both LEO and BLEO missions.  He then talked at length about the challenges needing countermeasures/mitigation.  He did not say these were showstopper challenges but they do require effective countermeasures.  For example, he said humans could probably survive a trip to Mars today providing the hardware & life support was up to the job but their goal is to get the crew there in good condition, to be able to do effective work, and to return safely.  He did not think those goals could be obtained today.  I asked if money was a primary issue and it was not though he said more money is always helpful. He talked about the time needed for some human studies, team studies, and research, sometimes extending even longer than a year.  He then took us through the three categories to tell us what NASA was doing & how it was doing in that research area. You might be surprised by what you hear.  I certainly was.  Later, we talked about ocular/vision issues which are now getting front page attention.  He explained the latest theory causing the problem as possible fluid shifts.  Listen to this discussion.  Note that once we start with BLEO HSF, we may find other problems that do not now show up now.  Also, we may develop a countermeasure for one problem but that opens the door to lots of other problems currently unknown.  One tool he talked about that was being tested on the ISS Russian sector was lower body negative pressure.  Artificial gravity was a big part of our discussion.  While everyone is enthusiastic about it, he made the point of saying we don’t know the needed spin rate nor do we know what level of gravity is needed for humans or for how long. Just spinning a spacecraft without knowing this information is unlikely to be successful let alone cost effective or economic. He also pointed out that artificial gravity is costly, requires lots of energy, a huge spacecraft which means lots of mass to orbit, & to do it, it needs to be done in a way that maximizes the benefits for the crew.  Without knowing the precise spin rate and gravity needs for humans plus how long the crew needs to be in artificial gravity, it is likely it won’t be done just for cost and economic reasons alone.  Charles emailed in about bed rest analog studies.  Joe sent in a question about lower back pain & spine issues.  As the segment ended, I asked him if humans were lousy candidates for BLEO spaceflight.  Don’t miss his answer.

In the second segment, we took a call from Dave about nuclear submarines as an analog for HSF studies.  Our next topic was space radiation which our guest discussed in detail.  I then took two email questions from B John in Sweden.  He asked about the benefits of microgravity for disabled folks, then I read a longer email from him suggesting solutions for the microgravity, psychology, and radiation issues already existed and why was NASA not proposing and developing “these simple non-medical solutions to the problems you describe.”  Dr. Shelhamer responded to his email item by item. For the most part, he agreed with what B John was saying except that his information and perspective were limited and missing key components of the scenarios he was talking about.  Mark explained why our listener’s comments were way too simple and cited some scenarios to illustrate this.  It was a fascinating reply to what many of us believe are already effective countermeasures.  Unfortunately, while what many of us suggest is correct, what we suggest does not go far enough and does not contain the specifics and details of what is actually required to make a specific countermeasure work.  Otherwise, the countermeasures are far more complex than what B John asked about in his email which you will hear me read on the program.  I asked Mark about genetic modification and that took us to the subject of personalized countermeasures.  We talked about pioneering/space settlement, childbirth & children in the space environment, even gender differences for BELO HSF.  I asked about the differences from his perspective of doing HSF to the Moon, an asteroid, Mars, or Deimos.  There are differences, don’t miss his response.  As the program was ending, I asked if a commercial company without gov. funding could decide to do a BLEO mission without all the costs and safety concerns of NASA.  Mark said it might be possible though the costs of the missions and the technology needed would make it very hard for a commercial company to carry out.  He said a short cut bare bones mission might be achieved by a commercial company but the risks for the crew would be extreme.  If you were running a commercial company and funding such a mission, would you accept these risks, plus the risk the crew might not be able to do much or be effective once they got to their destination? As the commercial company CEO, would that be a good use of company money or would you dismiss what people like our guest today have to say about these issues.  Let me know your thoughts by posting them on the blog.

Please post comments/questions on TSS blog above. Mark can be reached through me or through his PPT presentation address.

We welcomed back Dr. Doug Plata for this two hour two minute discussion.  NOTE THAT THREE SUPPLEMENTAL DOCUMENTS FROM DOUG WILL BE UPLOADED TO THE BLOG.  During the first segment, Doug introduced us to the topics he discussed at the recent ISDC conference in Los Angeles.  He talked about SpaceX and both the Falcon 9 & Heavy, Lunar ice, hollow ice, a concept he calls Moon for Mars, and more.  He also suggested that the Moon was not necessary for a Mars mission.  Additionally, while he certainly support a return to the Moon, he does not believe bringing back the VSE and Constellation is the way to do it.  I asked him how he got is interest in and start in space advocacy about 4 years ago.  Doug told us an interesting story, including how he was influenced by the LCROSS mission.  Michael Listner called to ask Doug about the WHY for the missions & projects he was advocating.  This was an interesting discussion though Michael got cut off due to a glitch at his end.  Tony wanted to know if Doug might be considering a start-up around his ideas in the near future.  Other first segment topics included ISRU, what makes space sustainable, and gaining the public interest and trust.  I asked him what among his ISDC topics was the least popular.  Listen for the answer.

In the second segment, Doug said people could find the lunar cots petition at http://www.lunarcots.com.  Doug addressed a question submitted by Tony regarding the use of water for radiation shielding.  Doug corrected some misunderstandings from his previous comment & went through the calculations in support of his conclusions.  We talked about a recent Mars One announcement for payloads for their planned 2018 mission.  Doug talked lunar cots, telerobotics, & benefits which he had sent me on an earlier show.  It is the three benefits documents that I will upload to the blog.  Doug had more to say on LCROSS & its impact on him.  He also told us about his newly made NASA HQ and commercial space contacts regarding lunar cots and cislunar.  As the program was ending, he talked about doing a special Flagstaff conference next year with a media event at nearby Meteor Crater.  Several times during our discussion, Doug cited Hops Blog for lunar and Mars lander/hopper ideas.  See http://hopsblog-hop.blogspot.com.

We welcomed back to the show Dr. Paul Spudis to discuss the NRC Human Spaceflight Study report recently released. You can download the report for free at http://www.nap.edu/openbook.php?record_id=18801.  Please note that this program was broadcast and recorded live on Wednesday, June 18, 2014.  It is being archived on Friday, 6-20-24 as there will be no live show on Friday due to the host travel schedule.  During the first segment of our 1 hour 36 minute program, Dr. Spudis first walked us through the NRC nearly 300 page study, hitting the highlights, raising questions, talking about what was good in the report and disappointing in it.  We talked about the rational for human spaceflight, for Mars, also the Moon.  We noted the absence of economic development in the report and this gave Dr. Spudis several openings to talk about his ideas for cislunar economic development.  Listeners asked lots of email questions ranging from budget issues, to SpaceX and rocket reusability.  Paul described much of what the study suggested as a form of “Apollo to Mars.”  Near the end of this segment we talked about public/private partnerships and learned that the Pathways study was only addressing public programs.  A listener asked Dr. Spudis what he thought the impact of the study might be and sitting on a shelf somewhere seemed a plausible answer.

In the second segment, Dr. Spudis focused on the response to the report and ways to actually develop a quality space program.  He talked about the need for a space transportation system, space infrastructure, and to use an incremental approach.  Robotics were discussed, we talked about the space media, and Dr. Spudis reminded us a few times that if there is no infrastructure, there can be no institutional use and capability.  We also compared the Apollo period and JFK’s goal for the Moon compared to now.  Its an interesting discussion, especially since we no longer have many of the skill sets we had back then.  The value of the Moon and commercial space came up & we talked about promoting the value to policy makers.  In supporting his incremental approach, Paul referenced a bit of US naval history.

We welcomed Ed Wright back to the show to discuss Citizens in Space and the new U.S. Rocket Academy Lynx Cub Payload Carrier they developed with the Texas A&M Space Engineering Research Center.  For more information, visit http://www.citizensinspace.org.  During the first segment of our 1 hour 34 minute program, Ed talked about space settlement per his recent talk at ISDC 2014 in Los Angles.  After introducing us to the topic, he talked about how space settlement needs to evolve to a permanent base by starting smaller and boot strapping along the way.  He explained the process as he visualized it and outlined how such a process, including how both suborbital and orbital flights would lead to job creation, eventually job creation in space.  As part over his overall strategy, he includes the Maker Faire movement and contrasted Maker Faire to a typical space conference where Maker Faire draws thousands of people and a typical space conference draws a few hundred to maybe a thousand people.  We talked about the role to be played by ISS, military space, and the challenges presented by the human factors medical issues as well as other technical challenges.

In the second segment, Doug emailed asking about the ISDC reception Ed got regarding his talk at ISDC.  Also, Charles emailed in during both segments to suggest the Microlaunchers approach and to once again voice his doubt about suborbital tourism becoming a successful industry.  We also talked about the Citizens In Space New Space Research Platform which is ready for flight testing, the Lynx Cub Payload Carrier developed with the Texas A&M Space Engineering Research Center and XCOR.  The carrier will be used on 10 Lynx mission and made available to XCIR customers as ready to fly hardware or even as open-source hardware.  You can read about it at http://www.citizensinspace.org/2014/05/lynx-cub-payload-carrier-ready-for-flight-test and at http://www.citizensinspace.org/2014/05/lynx-cub-payload-platform-will-be-unveiled-at-makercon.  Ed then explained how Citizens In Space is broader than his earlier program, the original Teachers in Space program, and that now preference for being flown to space goes to those submitting science experiments for the upcoming suborbital flights using the Lynx Cub Payload Carrier.  He offered excellent closing comments.
