We welcomed Dr. Frank Martin to the program to discus the NRC human spaceflight study along with all aspects of human spaceflight including various destinations and missions.  During the first segment of our 1 hour 39 minute show, Dr. Martin introduced us to the NRC Pathways study which you can download for free by using Google.  He suggested it was a dose of reality as well as optimism.  He said the study was very clear in saying “show me the money” for those wanting to do humans to Mars missions now or fairly soon and then explained some of the high costs and trades involved in these missions.  One of his overriding themes throughout our discussion was the need to manage a very large mass in LEO in order to accomplish the goals of long duration human space mission.  During our segment, we kept coming back to the need to manage a large mass in LEO and how this translated to costs as well as the need for technology advancement.  Both myself and listeners asked our guest about doing human missions cheaper by using the private sector.  This subject kept coming up during both segments of the program.  We also addressed the rational for human spaceflight.  In addition, the issue of walking away from HSF was looked at for the US as a nation as that is an option. The report attempted to address this and related issues.   Joe sent in an email about the mice on the ISS and using them to determine the gravity RX for HSF.  He sent us several additional emails on this subject as well.  This prompted comments about the need to use the ISS for research in support of long duration HSF missions.  Dr. Martin said Mars was an horizon goal.  In this context, he talked about only a few other possible destinations near us, either the Moon or an asteroid.  He then proceeded to address the issue of managing the risk for a Mars mission.  Beverly asked a budget question and taking the lead from the most recent Mike Griffin interview, she asked Frank if it really was just a choice to be constrained by budget issues.  While Frank agreed it was a choice, he said there were very good ways and choices to spend taxpayer money so he did not see significantly more money for space in the future.  Another listener talked about nuclear propulsion which also crossed into the second segment.  Near the end of the first segment, we got a call from a New Zealand listener.  During his call, the idea of the Buzz Aldrin Mars cycler came up and there was a question or two about fuel depots.

In the second segment, I asked Dr. Martin why the study took 18 months, then SLS John called the program.  John wanted to talk nuclear propulsion thinking it would be a cost saver but what was not known was the accurate cost of the R&D program or the cost for jumping through political hurdles.  John suggested a new administration would make a difference and I challenged that.  I asked Frank given all his years of space industry experience if it was reasonable to expect big changes in space policy due to a change in administrations.  Don’t miss Frank’s reply.  Dwayne called back to question the HSF rational. One of the points made by Dwayne was that cooperation with the Russians on the ISS does not modify Russia’s behavior other than for space.

We welcomed Stewart Money to the show to discuss his new ApogeePrime published book, “Here Be Dragons: The Rise of SpaceX and the Journey to Mars”  You can get much more information by visiting http://www.innerspace.net along with http://www.apogeeprime.com/prime/bookpages/9781926837338.html, and http://www.amazon.com/Here-Dragons-Rise-Spacex-Journey/dp/1926837339/ref=sr_1_1?ie=UTF8&qid=1411235694&sr=8-1&keywords=here+be+dragons+the+rise+of+SpaceX+and+the+Journey+to+Mars.  Remember, if you buy this great book through Amazon, use the OGLF Amazon portal (instructions on the OGLF & Space Show websites plus all archived programs on the blog and The Space Show website) & Amazon will make a contribution to The Space Show.  During the first segment of our 90 minute program, Stewart explained why he wanted to write a book about SpaceX to tell the story from the beginning up to current SpaceX history.  We spent lots of time talking about the early days including the Mars Oasis Project, the forming of SpaceX in 2002 and the three questions that Elon asked prior to starting the company.  Stewart’s book and our discussion take you step by step through the emergence of SpaceX through each stage of its development.  Even if you are familiar with the SpaceX story or the basics, you will learn much from the book as well as listening to Stewart as he narrates the SpaceX story and responds to listener email questions along with my comments.  Some of the questions asked him were for the biggest challenges Elon and SpaceX faced plus the most important successes.  He was asked for the origin of Elon’s interest in Mars and if the Mars interest was a company wide passion and belief.  In response to a question about the biggest SpaceX failure, Stewart said it was the inability to enter the EELV national security launch program on his timing.

In the second segment, a listener wanted to compare the SLS, Falcon Heavy, and MCT with one another.  Questions were asked about the unveiling of the Dragon V.2 as Stewart attended the ceremony.  Others wanted to know about SpaceX launch sites at the Cape & in Texas.  Andrew asked about SpaceX PR & damage control when necessary, Dana asked if SpaceX was interested in space tourism & Larry asked about reusability.  Stewart said it was a core value for the company.  Stewart provided us with a good, brief summary of our discussion and what he considered to be a priority take away from our discussion.

Please post comments/questions on TSS blog. You can reach Stewart through me.

We welcomed Dr. Bill Rowe back to the program to discuss cardiovascular issues for human spaceflight & EVAs, plus many other issues pertaining to long duration spaceflight.  Note that we experienced serious phone line issues with Bill about 12 minutes into the program forcing us to stop for repairs.  Evidently the fiber phone lines now serving Dr. Rowe cause broadcast equipment problems.  Bill was able to go to a neighbor’s house to do the show but you will hear some line issues plus unusual cuts as I spliced together part of his opening to the point we were able to resume with a good phone line.  Once past that point, there were no further phone line issues.  During the first segment of our 2 hour 11 minute program, Dr. Rowe introduced us to his discussion main points and we began using his website for references throughout the show.  It is important to be on his website and go where he points at various times in the discussion (see http://www.femsinspace.com).  While parts of the discussion relied on medical terms and descriptions, our guest did an excellent job of breaking it down for us non-medical types to easily understand the information he was sharing with us.  Among the issues we talked about were cardiac issues that don’t present symptoms, plus the problems with increased adrenalin secretion in the body which happens in space.  Dr. Rowe spent significant time discussing the adrenalin issues citing known astronaut examples.  In fact when talking about the adrenalin levels in space, he said that within five days of being in space the levels are twice that of being on Earth.  Another issue brought up was possible cardiovascular damage for excessive exercise and here he cited the research projects he had been involved in with marathon running athletes.  He strongly suggested the use of regularly taken electrocardiograms on the crews while in space.  Next, Dr. Rowe talked about EVA issues, specifically cooling.  He explained other risks and made the case for future robotic EVA missions instead of human mission.  Before the segment ended, he had much to say about exercise in space.

In our second segment, Bill reviewed for us his comments on oxidative stress and suggested we follow along with his website submarine model, http://www.femsinspace.com/Oxidative_stress.htm.  A listener then emailed in that the ISS did have an ultrasound on board which could be used for the purposes Dr. Rowe suggested (see http://www.nasa.gov/mission_pages/station/research/benefits/ultrasound.html).  Bill talked more about lunar dust toxicity plus magnesium and calcium usage in space and in general.  He referenced former astronaut Jim Irwin losing consciousness for a brief time on the Moon & he provided the reference for that fact.  Rodent research on the ISS was discussed, then he got a listener question about possible different health standards for government trained and fit astronauts as compared to space tourists and possible private sector astronauts.  Near the end of our discussion, space tourism came up and he pointed out risks for the middle age, overweight segment of the space tourism market.  Bill spoke to pharmaceutical use in space and the issues with it.  Just before ending our discussion, he pointed out that for Mars he thought an all female crew was best given the advantages they have over men.  He did explain his comment.

If you have comments/questions, post them on TSS blog above.  You can reach Dr. Rowe through his website or me.

We welcomed back Bob Zimmerman to discuss current and hot topics happening in space at this time.  During the first segment of our 2 hour 6 minute discussion, Bob asked me about the recent Bay Area-NAPA earthquake on Sunday morning, August 24, then we switched over to space topics starting with SpaceX and the Falcon 9R test launch explosion.  Next, Bob talked about the failure of the ESA Galileo GPS launch involving the Soyuz-Arianne.  Several questions came up regarding the ESA GPS system. We also talked about other regional GPS systems.  Bob moved us to the launch failure (booster rocket) for the Air Force Hypersonic vehicle, then to the decision by Sea Launch to take a break.  Bob had much to say about the Sea Launch partnership now involving mostly Russia and the Ukraine.  Russia and the ISS came up and here Bob also had much to say, including going over the news that Russia may now be interested in extending the life of the ISS.  Bob suggested some important Russian reasons for wanting to do this, see what you think.  The Atlas RD-180 rocket engine came up for discussion as did the upcoming NASA down select for commercial crew with Dream Chaser, SpaceX, and Boeing with their CST 100.  Next up was SLS which I permitted to be discussed for a while, including a call by SLS John in Ft. Worth, then I stopped it and said that SLS was a beaten to death topic on the show and that listeners and I were sick of it.  I said no more SLS talk unless there was something new on one side or the other of the SLS issue.  At one point I even assigned SLS John a new topic to research and call in about.  Let us know with your blog comments, are you sick of SLS discussions on TSS? Do you want to keep hearing them or not?  Luis emailed in about having GPS redundancy and backup systems re the European system as an example. Bob had specific ideas about this but thought the better route would be to be able to quickly replace a lost or destroyed satellite.  As the segment neared its end, Joe asked about CST and Falcon 9/Heavy & Bob had more to say about ISS modules & Doug asked a series of questions about the benefits of extending ISS to 2028.  Don’t miss Bob’s response.

In the second segment, Joe asked about small sats taking over market share from the previous big satellites.  Bob provided an interesting short discussion on this topic.  SLS John called back about the Falcon Heavy flying and then somehow the discussion focused in on presidential candidates and their space policy in upcoming elections.  After a short non-partisan review of what Bob thought might unfold depending on which party wins in November, we moved on to Rosetta and 67 P.  Bob talked about the lander and the landing sites.  Tim called in to talk about a proposal announced for space debris tracking with Lockheed and Electro Optic Systems in Australia (see http://www.lockheedmartin.com/us/news/press-releases/2014/august/0825-ss-electro.html).  Also discussed was nuclear propulsion, the Space Fence, then we got emails about fusion energy progress.  Near the end of the program, Bob talked about Curiosity, some of the electrical issues with using the on board drill, and of course the tire problem.  As the show was about to end, Kirk emailed about the recent Chinese ASAT test and Bob suggested we look for an end of the year Dragon abort test, another Falcon 9 flight and more flight tests, and the Rosetta landing on 67 P scheduled for November.

We welcomed NASA Astronaut Dr. Rick Linnehan to the program to discuss animals and their place in space in history, the present, and the future, plus human concerns for long duration spaceflight.  During this one hour program, we stared off by asking Dr. Linnehan for an overview of the role played by animals in space, including looking to the future for animals for agriculture, research pathology work, comfort, & other purposes.  We talked about microgravity issues and countermeasures, then I asked specifically about taking chickens to Mars for feed purposes.  Our guest talked about the effect of microgravity on chickens and the egg laying process.  He said a few times that while we might likely evolve over many years, decades or even longer to having a larger role for animals in space, most of the ideas and concepts today are pie in the sky.  We talked about some of the animals that had been and are in space including lab rodents, fruit flies, some small fish and others.  Our guest talked about the space acclimation process for animals, including the small fish, and we learned that in many instances the animals acclimate to microgravity faster than humans.  Our guest mentioned the need for advanced propulsion for long duration human spaceflight and suggested that Mars was on the edge of the possible using chemical rockets.  Rick mentioned some of the other human factors issues such as radiation and psychological challenges.  We also discussed astronaut exercise routines and the countermeasure exercise equipment currently being used with efforts underway to redesign the equipment to be more effective and lighter.  Several questions came up about private sector humans to Mars missions and crew health.  When asked if we could do a humans to Mars mission now or by the early 2020s, our guest said yes but listen to the details of this discussion.  Also, with regards to the private astronaut missions to Mars or elsewhere, several questions arose about the conditioning of the private astronaut crew, what microgravity countermeasures and exercise equipment they would have on board, what routines they would strictly follow and more.  Our guest was mostly referring to space agency astronauts in terms of our readiness to do human spaceflight to Mars now or the very near future.  He was unable to address private astronaut missions or their details because they are unknown.  We did talk about gravity and the absence of it in spaceflight, both for humans and animals.  Advanced propulsion questions and comments kept coming up during the entire show. At one point, I asked how essential advanced propulsion was for long duration human spaceflight and he said there would be no long duration spaceflight without.  Listen for the details regarding his opinion on this issue. Doug called to ask about bacteria, DNA, cat implants and more.  Artificial insemination came up with regards to surrogate species.  Doug also raised questions about the size for a minimum viable population.  After Doug’s call, I asked what our guest thought the priorities should be for Mars human spaceflight.  He listed advanced propulsion technology as first followed by human quality of life issues which he described for us.  I also asked questions about crew compatibility for psychological reasons as well as the probable command structure for the crew on a long duration human spaceflight.  One listener asked Dr. Linnehan about the differences in a zoo vet as compared to the typical vet we use for our dogs and cats.  Larry emailed in to ask if an animal had ever been on a space walk.  Rick said not his knowledge, talked about the need for an animal EVA suit of which there are none, and when I asked about taking an animal with an astronaut on an EVA for research purposes, he explained why that was impractical.  The microgravity simulation work in the NASA neutral buoyancy pool came up and our guest said that for about every hour he spends on an EVA, he would have spend about 12 hours in the pool.  Near the end of our hour long discussion, Jack emailed in for the best goals for human space flight.  Our guest suggested evolving stage by stage with cislunar, La Grange points, lunar settlement and out further and further to other destinations as our capabilities and technology improved.  B John had emailed in a few questions about microbes and the sea plankton announced by the Russians as existing on the outside of the ISS.  While we discussed these questions earlier in the show, near the end I asked our guest his question about microbes traveling greater distances in space than humans have and if our missions that have entered interstellar space carry microbes with them.  In his summary, Dr. Linnehan stressed the importance of continuing to explore space, to leave our planet, set up settlements, and to do what we can to keep pressure on the policy makers as we know the importance of space development and exploration.  He supports the private/commercial efforts and missions and even suggested he would do a one way Mars trip to help open up a Martial settlement.

We welcome you to these two interviews recorded at the AIAA Space 2014 Conference in San Diego, CA from August 4-7, 2014.  The first segment or interview on this nearly two hour program features Larry Price, Deputy Director for Lockheed on the Orion project.  In the second segment or the second interview, I recorded a Sierra Nevada Dream Chaser press conference featuring Dr. Mark Sirangelo.  As you will hear from my introductory comments on tape, both segments faced audio challenges.  Also, I missed the full opening statement by Mark re Dream Chaser and I apologize for the perhaps 1 minute omission.  I joined the press conference in session.  Regarding Orion, Larry provided us with an update on Orion’s progress, we talked about the heat shield, the coming December flight test on the Delta 4 Heavy, Atlas 5 issues, the type of missions Orion can fly including lunar and cis-lunar missions along with Mars, Martian moons, and asteroid missions.  This was a broad ranging discussion regarding Orion and deep space human missions.

In the second segment, or the press conference regarding Dream Chaser by Sierra Nevada, Mark provided us with scheduling and testing information and flight status reports.  He also carefully defined the Dream Chaser mission, goals, and objectives.  We talked about launch vehicles should Atlas 5 RD-180 issues for a launcher change.  This included the possibility of using a Falcon rocket.  Mark took audience questions. Several wanted to know Dream Chaser’s intention of NASA did not down   select them in the commercial crew process.  I raised the volume on the audience questions as much as I could but if you do have a problem hearing the question, I believe you can figure it out based on Mark’s answer.

Please post comments/questions for either segment and guest on The Space Show blog above.  I will make sure to forward your comment to the appropriate guest.

We welcomed back Bill Harwood, veteran CBS Space Reporter, to talk with us about the recent success with the Orbital Sciences Cygnus ISS resupply vehicle plus the last ESA ATV 5 resupply mission now in orbit and due to dock with the ISS on August 12.  We spoke in general about ISS resupply and the download capability of the SpaceX Dragon.  Bill was also asked about the US goal of extending the ISS to 2024 but we wondered if Russian and the other ISS partners would go along with that extension.  At this time, it is an unknown.  The subject of US sanctions against Russia came up and Bill said that so far the sanctions had not impacted the ISS but that the station needs both the American and Russian sides to fly and maintain the station.  Bill did not know if the terrestrial politics would remain outside the space and ISS relationship with the two countries.   Bill also explained why ATV5 was the last ATV resupply mission.  We covered other topics as well during this Hotel Mars segment.

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.
