Welcome to our Open Lines show and my return to broadcasting given my post surgery recovery from my Oct. 1 spinal sugary. It was great to be back on the air. During the first segment of our two hour show, I updated everyone as to my post surgery recovery progress, I dedicated the show to the memory of our near friend Declan O’Donnell who passed away October 1 of this year, then I updated everyone on the progress being made on our new website development project and my ability to start fulfilling Indiegogo perk orders. As I stated, there have clearly been delays due to the first two weeks post surgery but we are getting back on track and I expect reasonable progress moving forward. As I explained I continue to have mobility limitations and sitting issues but things are improving all the time so I expect the delays will soon be a thing of the past. Several times during the program I mentioned booking future guests now that I am back on the air and suggested those of you that selected the co-host perk or the host your own show or be your own guest perk take advantage of the available dates for the balance of 2015 to bring your co-host guest to the program, or your host your own show to the schedule. Let me know and I will support you in invitations, etc. to get these programs booked with you even before the new website is launched. I also read an email from Matt from Switzerland who wanted to follow up from the earlier show with Ally regarding some sort of online virtual space advocacy training. If this interests you, post comments and your ideas on The Space Show blog. Matt will see them and maybe interested parties can get something going. Our first caller was Dr. Rowe who expressed misgivings about all the talk about being able to have humans walk on Mars by 2030. Dr. Row cited some of his well known and highly regarded medical research in support of his statements but as usual, committed space advocates challenged him. One was by text message to me which I did not read on air but was highly critical of Dr. Rowe wondering who he was and why in the world he would be talking about such things. Via a reply text I did tell this listener who Bill was and briefly listed his credentials for his research. I know his work is controversial and many listeners to this show do not support Bill’s conclusions but that does not invalidate his work. Doug asked Bill about running the numbers for what propellant it would take to spin up a craft with a tether long enough to get one gee but relatively low RPMs as the subject moved to needing to be in 1g and maybe even marginally less gravity would not work for humans. Lots of discussions followed about the gravity prescription issue, the need to know it for BLEO spaceflight, then Doug expressed his ideas of why it was not so important to know the gravity prescription at this time. Don’t miss Doug’s full comments on this subject and see if you agree with his perspective or not. Bill had some other medical issues to talk about, especially cardiology issues with Irwin and Armstrong. I have tremendous respect for Dr. Rowe’s work though I am not qualified to do any type of due diligence on it as I am not a medical doctor. Still, knowing it is controversial, especially with segments of The Space Show audience, I urge space cadets to be more open minded rather than married to agendas. In the end, Dr. Rowe’s work may prove more valuable and important than many think or would like to think. After a decent discussion with Dr. Rowe and listeners on related topics to Bill’s phone call, we started talking about the movie “The Martian.” This discussion took us through the rest of the show with breaks here and there for different or related topics. Everyone who called to talk about the movie like it and we did have some fun discussions about the movie and maybe some different scenarios.

In the second segment, John from Freemont, CA called to talk about the movie. he also talked about the gravity prescription and the plans by the SSI to do some sort of gravity prescription experiment. I talked about that as I have done shows on it and spoken to Gary Hudson about their efforts to fund this experiment,. He also mentioned the SpaceGAMBIT Organization which sounds very interesting. Check it out at www.spacegambit.org. June from Tucson emailed us wondering why there was criticism of the NASA Roadmap To Mars. I started answering her somewhat reluctantly but Doug called and I passed the response to Doug who handled the reply to June with a few side comments from me. In the process of talking about the roadmap, we talked about going to Phobos, cislunar development, SLS launches & much more. Doug then spoke about the movie which was the main reason for his call. During the conversation I incorrectly referenced a Dr. Lurio text to me over the weekend but fortunately Charles was listening to the show, sent me the correct text which I read on air. Charles then called the show and we had a good discussion about the movie, sci fi in general, and certain issues surrounding the movie. He also went into detail on the three items that made him see Hermes in the context of 2001. Advanced propulsion came up and several us wondered why nuclear propulsion was not a NASA solution to the rescue of the Martian. Here, we talked about the movie being about a NASA government program, not focusing on commercial or Newspace. Dr. Lurio offered a reason for this and I reminded listeners of this topic on the interview we did with Andy Weir several months ago. John Hunt called and we talked about audience and age differences with the movie. The last caller was Tim from Huntsville who saw it with friends, including non-space cadet friends. The non-space cadet friends liked the movie as much as the space oriented people liked it.

John Batchelor and I welcomed Dr. Robert (Bob) Zubrin to the program to discuss the NASA Road to Mars per the Evolvable Mars Campaign: Status Update as published Sept. 22, 2015 by NASA Spaceflight.com at www.nasaspaceflight.com/2015/09/sls-manifest-phobos-mars-2039. John and I asked Bob about parts of the plan including 41 SLS launches, cislunar development missions, a mission to Phobos and then finally in 2039 a Mars surface landing. Bob was highly critical of all stages of the plan. He also said it was the subject of a big debate at the recent Mars Society Conference. You can see the debate Dr. Zubrin referenced at www.youtube.com/watch?v=Oo4-ros2yEk&list=PLn0lnGc1SaimPHpRoH0XlwiCih-jYjC7F&index=11. Bob called the NASA plan absurd, was highly critical of plans to go to Phobos saying the science was at Mars, not on Phobos, plus he described orbital challenges and difficulties created by going to Phobos. Several times he said the plan was nothing more than a way to spend money on NASA projects. Near the end of the segment I asked Bob about the plan being sustainable and also leading to the settlement of Mars. You can imagine his response to my questions. In summary, he said a humans to Mars mission needs to be done from start to finish within the two terms of a president, not spread out over 25 years as is the case with the NASA Road to Mars program.

We welcomed to the show Dr. Jens Biele of the DLR to discuss the Philae Lander as part of the Rosetta Mission to Comet 67P. During the first segment of our 1 hour 27 minute discussion, Dr. Biele summarized the Rosetta mission going back to its planning and development days, the flight to Comet 67PM and the Philae Lander’s anchor landing failure which he talked about at length. He also talked about communications from the lander to the orbiter and the narrow window for successful communications. We talked about solar and battery power, the type of data it can still transmit and related issues. Later, he was asked about other forms of propulsion including ion thrusters and advanced propulsion, plus he was asked if it would have been better to power the spacecraft by an RTG. He summarized some of the trades involved in making these types of decisions so don’t miss the discussion. BJohn asked about other DLR missions so MASCOT was discussed and later he discussed AIDA and AIM. As part of this discussion flyby missions were detailed and trojan asteroids were discussed. The subject of searching for life came up along with the discovery of organic molecules. Near the end of the segment, Roger from Rutgers asked if they considered Philae a success. Don’t miss his answer to this one. Other topics in this segment including drill samples, mission operating cost considerations, launcher choices and the shape of 67P which was a puzzle yet to be explained.

In the second segment, I asked our guest about the extremely long mission planning and design times coupled with the very long flight time and how that impacted people wanting to work space projects. As you will hear, it is not much different in Europe than here in the States with the same issues with NASA missions here. BJohn asked additional questions about future DLR missions and robotic exploration. This is the discussion that talked about both the AIDA and AIM European missions. Listener Helen asked about general European public support of ESA and space. You might be surprised by what our guest had to say in response to Helen so don’t miss it. In this context, Dr. Biele talked about ESA PR and its limitations and constraints. Toward the end of our program, he talked about human spaceflight, referenced Mars and going to Phobos as an initial part of human Mars exploration. When I asked our guest for closing comments, he said “If you dare you win. Take Some risks.” His final comments were ” Landers are cool!”

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

We welcomed Brent Sherwood back to the show to discuss NASA planetary science missions and in particular the Discovery class missions.  During our nearly two hour discussion without a break, Brent started out by telling us how NASA selects Discovery class missions.  He talked about the two kinds of science but focused on the Discovery missions which have a $500 million budget not including launch or operating costs.  He said it was open season on the solar system other than the sun or Earth as they were covered by other NASA programs.  In speaking about the history of Discovery missions, he named a few that we are all familiar with such as Kepler, Grail, Deep Impact, Stardust, the Phoenix Mission, Dawn and the upcoming Insight Mission to Mars.  Brent then explained the proposed missions under the auspices of his team.  These proposed missions include VERITAS, BASiX, CORE, Pandora, Proteus, Psyche, Kuiper, and ELF.  Brent explained each proposed mission to us, talked about the P.I. for each mission, and the science to be gained from the mission.  Listeners had many questions for him including how the principal investigator (PI) was selected.  Brent explained the process, where the PIs come from, how a mission is proposed, is it coming from a university or academic setting, has it been proposed before, or is it coming from JPL or another NASA center or the Applied Physics Lab (APL).  Brent was clear that Discovery missions, given their limited resources, were not about developing and proving out new technology so in answer to my question about the TRL of completing these missions, he said they were all coming in with very high TRLs though the missions sound very futuristic, even bordering on science fiction.  As for timelines, Discovery missions approved now would fly in 2021 so they have about a six year time frame to be developed and flown.  In response to questions, our guest addressed this six year time line in some detail.  All of these missions sounded very exciting but as Brent said, it is a very competitive process and only one or two if any of them may be selected as other teams are proposing their Discovery projects as well and they are equally exciting.  Later in the segment, Brent was asked about the choice of launch vehicle for each project.  This was a very interesting discussion, don’t miss it as our guest explained in detail the role of the PI regarding the launch vehicle and how NASA actually selects a rocket for the mission.  In response to BJohn’s question about launch costs, they certainly factor into the mission planning. Doug asked a question about the Photos-Deimos mission and if the mission could identify a favorable small crater which could later be the site for a covered habitat and if it could identify frozen volatiles in the polar craters of those moons if they exist.  Brent said it might have such capabilities but that these missions only do the work specific to their actual project.  He had more to say on this so don’t miss all his comments.  BJohn asked why not a Uranus mission.  Brent said Uranus was too far out and too costly for a Discovery class project.  Near the end of the segment, BJohn also asked about the importance of miniaturization now and for the future with NASA and these missions.  Brent said it was very important and then updated us on all the cubesat opportunities and uses being integrated into NASA missions.  He spoke about the significance of cubesats for several minutes so don’t miss what he had to say about them.  Doug asked a question about realizing economic value from these missions or at least what was the rationalization behind these purely science missions.  Brent provided an excellent answer to Doug’s questions so don’t miss it.  We ended the show after Brent’s response.  See what you think of it and post your comments on TSS blog.  Doug sent in a final note saying “I agree with his answer re: the value of science.  I believe that it is worth a certain amount of our money to increase our knowledge for its own value.”

We welcomed Dr. John Jurist and Kobi Hudson to the program to discuss their recent experiences at the Orbital ATK 5 segment booster test in Utah and the ISS algae experiment Kobi and his teammates are working on at this time.  During the first segment of our 1 hour 58 minute discussion, John and Kobi talked about viewing the Orbital ATK 5 segment booster test this past March in Utah.  John has attended all the 5 segment booster tests but this was the first one for Kobi who is one of John’s students at Rocky Mountain College in Billings, MT.  Kobi described the test, what it looked like and how it felt from the viewing area, the networking opportunities he had with those attending the test including many executives from across our aerospace industry & NASA.  I asked John and Kobi if they sensed that the Orbital ATK team was aware of the controversy surrounding the final destination for the booster, SLS.  We talked about this for several minutes.  I think you will find what both John and Kobi had to say about this to be very interesting.  This discussion took us into an SLS discussion but from a slightly different perspective than our usual Space Show SLS discussions.  A listener asked our guests if either of them noticed a cultural difference in the test team given the Orbital and ATK merger.  Kobi was asked if the test and the experience inspired him to want to work in the aerospace field which it did.

 

In the second segment, Marshall called to inquire about the use of liquid rocket motors as compared to solids and wanted to know which type was more efficient. Both John and Marshall seemed to agree that it might depend on which type of propulsion system gets more launches and usage though the solids are far simpler.  As part of this discussion, the political dimensions of decision making were brought up as they play a role in the propulsion system and thus influence efficiencies.  Next, we turned to Kobi to explain to us the algae experiment he and others are working and which will fly to the ISS on the SpaceX 7 launch.  Behind this experiment is the goal of testing how well algae grows and how much carbon dioxide it consumes in a zero-gravity environment.  They want to see if it can influence the presence of oxygen in the spaceship.  The algae is grown in an agar solid media.  Kobi went into details on this experiment which I believe you will find of interest. When the team gets the data back from the 28 day test, Kobi will come back to the show to update us on what they found out.  Later in the segment, SLS John called in to follow up on our earlier SLS conversation and the proposed NASA ARM.  Several listener questions came in by email regarding both the issue of solids vs. liquids and the algae experiment.  Kobi also got a question or two about this work on the Firebird cubesat program.  He said it used a polar orbit , was then asked if cubesats could go to the Moon or elsewhere and he said probably but challenging. Doug called to talk closed loop life support and related issues.  The last question came from a high school senior asking Kobi about the need to attend a Tier One school and the consequences for going to a school not as well known and not as highly ranked.  All three of us, Kobi, myself, and John responded to this question saying about the same thing but in different words.  Both John and Kobi offered concluding comments you don’t want to miss.

Guest:  Andy Weir.  Topics:  We engaged author Andy Weir in a thorough discussion of his best selling book, “The Martian” along with the essential engineering & needed technology for survival.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, https://thespaceshow.wordpress.com.  Comments and questions should be relevant to the specific Space Show program.

We welcomed best selling author Andy Weir to the program to discuss his book “The Martian.”  For more information, visit his websites, http://www.andyweirauthor.com and http://www.galactanet.com.   During the first segment of our 100 minute show, Andy started out by telling us how he came up with the story idea, & his three years spent in writing the book.  I asked if he used consultants, NASA, or other aerospace experts.  He said no & that most of the feedback and help came through suggestions from people who read the chapters he put up on his website.  Andy also did his own research, math work, physics, and engineering analysis.  He talked about a few errors that were pointed out to him & indicated that the most challenging work were the times and orbits regarding Mars and the missions described in the book. During the show, Andy got lots of email questions and phone calls regarding certain story lines and sections of the book.  He was also asked about life on Mars but that issue was not relevant to his story.  He did get questions about the human waste recycling carried out on Mars & why he chose Mars and not the Moon or another destination.  Sandra asked him about the private space company plans to visit and/or settle Mars given how hard it was for Andy’s character, Watney, to survive.  Andy had very interesting comments on this question including the Elon Musk Mars plans and then Mars One.  Human factors were brought up including radiation, microgravity, vision problems, and more.  Andy did address these issues in the book so listen to his reply to this line of questioning.  As the segment ended, we talked about using Phobos and Deneb for Martian navigation along with Watney’s trek to get to Pathfinder to use its parts for communication.  NASA came up several times in the segment as readers get a pretty good “view” of NASA problem solving, information, data, and PR control, plus amazing creativity.

In the second segment, we had lots of listener emails and phone calls.  Andy was asked what science fiction had influenced him, then he got an interesting email from Andrew in Tucson who had actually worked on the Pathfinder hardware.  Andrew said Andy was spot on accurate!  Dr. Doug called on many topics including using the Hohmann Transfer Orbit which Andy did not use as he designed Hermes, the big spaceship, to work with constant acceleration using ion propulsion.  The Aldrin Cycler was also mentioned.  Listeners mentioned the new movie Interstellar and made some comparisons if they had read “The Martian” and seen the move.  In both segments, we talked about “The Martian” being made into a film for release in a year.  Andy said so far the scriptfollowed the book but he did say he has no editorial input to the movie.  We got a call from Curt in Taiwan who wished there was a PG version of the book given he wants his kids to read it and some of the language is course.  Sara emailed us from Denver asking if Andy had considered making the hero character Watney a woman instead of a man.  Tim was the last caller & he wanted to know if the hard science & engineering would be in the movie.  During this final segment, Andy was asked about how he got to Mars without a transfer orbit.  He suggested we view his animated video on this at http://www.galactanet.com/martian/hermes.mp4.  In addition, he referred us to his Google talk.  You can easily find it by searching for “Andy Weir Google Talk.”

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

We welcomed both Dan Freyer and Tabor MacCallum to discuss the upcoming Space Tech Expo to be held in Long Beach, CA from April 1-3, plus Tabor told us about World View near space balloon rides and their work on HSF missions to Mars.  There was only one segment for this one hour program.  We started with Dan who gave us an overview of the Space Tech Expo (www.spacetechexpo.com).  He talked about the free program, the paid program, the exhibits, and the B2B focus of the conference.  We went through the paid Expo agenda which you can find at http://www.spacetechexpo.com/conference/conference-program-2014.  Dan stressed the business 2 business focus of the expo, talked about the mix of aerospace, defense, military, satellite, launch vehicle companies and executives that will be attending. We also talked about the exhibitors and their ability to tell attendees about their products and services.  Taber jumped in to talk about the World View near space balloon rides which they will be talking about at their booth #4042.  Dan also went over the conference logistics and fielded several questions asking about NewSpace representation at the expo, the possibility for students & interviews, networking opportunities, lunches with the paid program, plus more.  Later in the segment, Tabor received several email questions about his work on the life support systems for human spaceflight missions to Mars.  He talked about going to Mars, Inspiration Mars, Mars One and a stepping stone approach that might include going to an asteroid and the moons of Mars.  We discussed the possible need to first go to the Moon to learn how to go to Mars.  We talked about closed loop systems, radiation & microgravity issues, plus the complexity of landing large payloads on Mars. We concluded our hour discussion by reviewing the Expo logistics, registration on their website, and the strong business focus for this conference.

We welcomed Dr. Farrand back to the show to talk about Opportunity’s 10th anniversary on the surface of Mars, Mars rovers in general and Martian science.  During the first segment of our 1 hour 37 minute discussion, Dr. Farrand was asked about 10 years for Opportunity effective Jan. 24 and to why he thought Opportunity was still going strong after ten years.  He gave credit to the JPL engineers that designed and built the rover and those that keep the systems going.  We talked about the loss of a few of Opportunity’s instruments over the past ten years plus the current science being done by the rover.  We also talked about its path to Endeavour Crater.  In response to one of my questions, Opportunity has traveled about 38 KM since it first landed on Mars ten years ago.  He also said the science was as exciting today as it was when Opportunity first started.  Listen to how he described the rover’s evolution with science and its work over the past decade.  From time to time, other Mars rover science questions and comments came up, especially related to comparing Curiosity to Opportunity.  Our guest was asked about Earth analog sites for Mars, then water on Mars.  Cathy asked how they kept the solar panels clear of dust for maximum solar power to the rover.  He said they rely on Martian winds to dust off the panels.  We also talked about bandwidth communications and the use of the Deep Space Network (DSN).

In the second segment, we talked about our guest’s, www.farrviewconsulting.com plus the pictures posted on the site. We also talked about the special rover exhibit now underway at the National Air & Space Museum in Washington, DC.  You can see some photos from the exhibit along with a picture of our guest on the website.  As you will hear, some of the photos in the exhibit were taken by Spirit before it suffered its untimely demise.  Bill was asked several questions about technology advancement from rover to rover and Mars in general.  Later, we talked about humans on Mars, the use of Phobos, and then Doug called in to ask if it was worth the cost to put humans on Mars given how many more rovers we could put on Mars for the cost of just one human mission.  As the program was ending, Dr. Farrand summarized his thoughts on ‘Oppy” and ten years, again giving a shootout to JPL engineers.  He said the outcome of Oppy was paradigm shifting!  The final question was from Sally asking about Martian fossils.  Don’t miss Bill’s final comments regarding this question.

We welcomed Howard Bloom back to the show for this two hour 6 minute complex space policy, leadership, commercial space and more discussion.  During the first segment, Howard worked us into discussions about space and pop culture, space leadership and policy issues, commercial and private space issues, and the SLS as representative of extreme pork taking down the space program.  This conversation included many side tracks including space art for inspiration, Von Braun, Chesley Bonestell, and more.  We talked about The Space Development Steering Committee, their focus on private space as well as space solar power (SSP).  As you listen to this program, you will realize this is not an ordinary Space Show discussion on these topics as Howard brings to us very unique and very broad important perspectives with important information.

In the second segment, Chuck Lauer called in to talk about the Darpa XS1 suborbital program and his company submission.  Later, Howard talked about Dragon and Cygnus plus the significance difference between the two.  He advocated for fuel depots and space infrastructure.  I asked Howard about a timeline for realizing the development/implementation of the project he was talking about.  He also talked about the ISS, Mars, Phobos, and L1.  Near the end of the discussion, Howard talked about his two Kindle books available on Amazon, “How I Accentually Started the Sixties” and “The Mohammed Code:  Why a Desert Prophet Wants You Dead.”

We welcomed Dr. Jim Logan and Dr. John Jurist to this special 2.5 hour Space Show classroom in-depth discussion on space radiation. We focused our discussion on deep space, Mars, the Moon and BLEO missions. Note that on both The Space Show blog (see above) and The Space Show Classroom blog (http://spaceshowclassroom.wordpress.com),  Dr. Jurist has a Power Point presentation on radiation.  During the program, our guests referred to specific slides that you will want to check out.  In our first segment, Dr. Logan started out by telling us about his interest in the subject, why he has been writing a paper on the subject for publication, and how this Classroom show came about.  He cited our short duration spaceflight experience, the Apollo missions, Space Shuttle flights, and then how things started to change when we had six month ISS visits.  Dr. Logan also made it clear that space was not a benign emptiness type of environment.  He said the reality was that interplanetary space was a sea of disruptive ionizing radiation wrecking havoc on biologic systems.  We moved forward in our discussion from that point.  We talked about the findings of the MSL RAD instrument regarding radiation on the way to Mars and on the surface of Mars.  Both John and Jim spent some time putting the RAD numbers through analysis to let us know what this means for human missions to Mars.  We talked shielding, possible materials, passive and active.  We talked extensively about water and the use of hydrogen as well for shielding.  Our guests addressed the two types of radiation, the GCR (galactic cosmic rays) and the CME/solar flare.  Here, John suggested listeners look at his slide 13 as we talked about protons and neutrons.  Jim said there was no magic bullet and talked about shielding effects of Earth’s atmosphere.  Pay attention here as Jim introduced us to the  RP scale.  For being on the surface, he said nothing less than RP100 would suffice.  For the vehicle, an RP5 was required.  John introduced us to career limits for radiation for men and women astronauts of different age but the career limits are for LEO and not BLEO.  BLEO limits are expected to be more restrictive when made public in April 2014.  Earth Mars transit times were discussed, especially in the context of Brian’s email that suggested a 180 day transit time.  Both our guests said that was unlikely with chemical propulsion and all of us again stressed the need for nuclear thermal propulsion.  Microgravity was talked about, especially in the context of side effects due to the radiation environment.  Jim then brought up the EVA subject and spacesuits.  Briefly, Jim said that quite possibly the ISS construction represented the zenith of EVAs which may become a thing of the past.  Don’t miss why he said this plus his description of serious spacesuit limitations.  We talked about life support to Mars and here Jim suggested we should use Open Loop! Again, listen to the rational behind this recommendation.  Don’t miss what our guests said about theories & movies making it sound easy to go to Mars and that the radiation would be nothing more than just a few more cigarette packs a year.  Our last topic addressed informed consent issues.

In the second segment, I asked our guests for a readiness timetable were there sufficient funding and technology advancements.  I also inquired if Russia, China, and others assessed the radiation risks in a similar way to the U.S.  We then talked about radiation and space pregnancy, fetus development, birth, and informed consent for the fetus, a baby, and a child under 18.  Ethical issues regarding child birth and space pregnancy were talked about as well.  Curt had sent in email questions which our guests answered, especially about drinking irradiated water and microgravity DNA damage & what this may mean for radiation effects.  Next, I asked Jim and John to tell us their 2-5 steps for the start of designing a Mars human mission.  Jim went first and listed Day 1 and Day 2 activities, John listed his top three priorities which were different than those suggested by Jim.  Don’t miss this discussion as its very instructive as to how to do or at least start mission planning for a human mission BLEO.  Roger sent in a question asking if the crew should be senior citizens since they have more resistance to radiation.  Don’t miss what our guests said about this idea.  It may surprise you.  Our next topic was would going to Deimos be easier.  Yes, it would but it would be a very different kind of human  mission.  Jim had some great comments about Mars gravity.  Briefly, he said it was the “best.” Later, when asked to compare the Moon and Mars, our guests said lunar radiation was worse than Mars.  Also, the Mars atmosphere does provide limited shielding while there is no such thing on the Moon.  Jim had earlier talked about a sphere being the perfect shape for an interplanetary spaceship.  Shelia emailed in wanting to know if heavy lift made a difference and if the sphere was so good, why were capsules being used? Don’t miss the response.  We then talked about the complexities of rendezvous and docking, especially in the context of fewer launches (heavy lift) as compared to many more launches (smaller rockets).  Near the end, I asked our guests if either thought our nation, the public, NASA, our leaders and politicians were sufficiently motivated to do a human Mars mission.  Jim did not think so and had much more to say in reply to this question.  John was more pessimistic.  Both thought it was more likely that the private sector would mount a human Mars mission rather than our seeing a government mission, but raising the needed capital might turn out to be a show stopper.  The three of us then talked about what it was like growing up in the 40’s, 50’s, and 60’s as compared to today.  John and I (John is a bit more than 2 years older than me) were probably more harsh than Jim in our assessment of today, but we all realize that the younger generations will be taking us to space, building the next smartphone and more. I talked about my visits to Google, Apple, SpaceX, etc. and the excitement in the air in belonging in their work forces which does not seem to exist with NASA. This opened the door for Jim to put it on the line about his NASA experiences and the potential opportunities providing NASA can somehow reorganize.  He did not think the type of reorganization he was talking about would happen.  Both our guests left us with excellent takeaway points and concluding pearls of wisdom.
