We welcomed Dr. Arlin Crotts back to the show to discuss his new book, “The New Moon: Water, Exploration, and Future Habitation” plus lunar related science and development issues & concerns. For more information, visit Dr. Crotts website, http://user.astro.columbia.edu/~arlin/research.html.  In the first segment of our 93 minute program, I asked Dr. Crotts to summarize lunar science and development progress since his last appearance on TSS, Oct. 27, 2009 through today.  Dr. Crotts had much say in this summary, especially with lunar water, hydroxyls, minerals, LCROSS, volatiles, and more.  Don’t miss this summary. Listeners asked many questions about INSITU Resource Utilization on the Moon, polar ice, water ice, volatiles, fuel possibilities, and more.  I asked if he had detected an increase in the public’s awareness of the Moon and many of these issues plus I wanted his thoughts on the private sector commercial opportunities and plans opening up for the Moon.  The balance of this segment featured calls and listeners emails asking about the lunar poles, volatiles, craters & the Resolve Mission.

In the second segment, Dr. Crotts was asked about the Lunar Mission One Kickstarter project and their wanting to drill 100m into the Moon.  Dr. Crotts did not comment on the project but did talk about why we needed more and deeper lunar drilling exploration.  Our guest also talked about his book in detail in this segment, saying it was very detailed, well documented and supported, and that readers would learn things about the Moon not previously known or written about given his access to original lunar exploration and Apollo documents.  Other topics in this segment addressed humans to Mars or the moons of Mars, the timing of human lunar settlement which he supported but not until we know much more about the Moon to do it safely and correctly.  We talked about this approach in some detail.  Space settlement was discussed and he said it would happen sooner or later but that we needed more lunar science first before we settled the Moon.  Near the end of the segment, Dr. Crotts was asked about NASA’s ARM project.  Space mining came up and then just before the program ended, Eric inquired about Transit Lunar Phenomena (see http://user.astro.columbia.edu/~arlin/TLP).  Tim was our last caller asking about the use of RTGs.  Dr. Crotts talked about reactors on the Moon and mentioned the smaller Toshiba 4G reactor.

We welcomed Les Johnson back to the show to discuss his latest books on popular science & science fiction, solar sails, and much more. In the first segment of our 1 hour 45 minute show, Les began talking about solar sails and their use to go to go around our solar system and eventually to the stars.  There was much interest in the solar sail subject so Les gave us a terrific somewhat technical lesson on solar sails.  We fielded many listener questions and we all learned much about solar sails, their potential, today’s capabilities, materials used, and more.  This was  an exceptional discussion so don’t miss it as solar sails are a very exciting technology for robotic spacecraft.

In the second segment, Les mentioned the Lunar Flashlight and Scout missions.  I asked our guest about the track record for solar sail missions.  If the mission launch was a success, the solar sail mission has been pretty good but there have been issues with the launches on some of the past solar sail missions.  I also inquired about solar sail work, research, and interest around the world and with other space agencies.  A listener emailed wondering if the use of a solar sail made a satellite or a mission more vulnerable to an ASAT type weapon.  We switched gears to talk about the science fiction work Les has done with Ben Bova  regarding mars with his book “Rescue Mode.”  Les talked about his parameters when writing science fiction plus I asked him about the feedback he gets as an author from both his popular science books as compared to his sci-fi books.  You might be surprised by his answer.  Nuclear propulsion came up for discussion and a few listeners wanted to know the human spaceflight awareness level of people when he gives lectures on the topic.  Interstellar flight was discussed as was the movie “Interstellar.”  As we were moving toward closing the program, Less said he believes HSF is going through a golden age and he explained why.

We welcomed Dr. Cameron Smith to the program to discuss interstellar spaceflight and our distant human future.  You can see his lecture on this topic, “Interstellar Voyaging: An Evolutionary Transition” at http://www.youtube.com/watch?v=CprziVZHqBk.  During the first segment of our 91 minute program, we talked about the biological and cultural challenges involving interstellar flight.  When asked why he was interested in this field and doing research in it, he talked about how important it was to influence for the good our distant human future.  He talked about human success over time in adaptation as humanity is adaptable.  He then spoke to the need for species insurance.  John in Florida called in with Mars archaeological questions, wondering what may be left of a civilization after a billion years or so. We also talked about models from Earth archaeology around the world in places like the Middle East.  Our guest said there were plenty of unknowns in trying to extrapolate Earth archeology to Mars.  Another listener asked about robots versus humans, a topic our guest had much to say about.  The bottom line is that humans are still a much better tool but robots are also needed.  We talked about ways to influence policy makers and the importance of influencing the public.  You might be surprised by some of our guest’s comments.  We talked about Mars and he said it was a good first step.  He was then asked about the Moon as a first step.  He cited a comment by Dr. Zubrin suggesting that regarding the Moon, “the cops are too close!” Listen to how our guest explained this comment.  I asked several questions about student interest in interstellar spaceflight.  Other topics in this segment included extra terrestrial life and questions about Cydonia which our guest said he had studied in detail and concluded it was not from a past civilization.

In the second segment, Cydonia questions continued to come in and Dr. Smith elaborated on his studies and conclusions.  The Swedish website Glanta came up as our guest had an article published on the site. Their English language site is http://glanta.org/?page_id=2.  The ISS came up with listener questions and our guest was critical of it since it still does not have closed loop environmental and life support.  The field of exobiology was discussed as was the need for low cost space access.  Paula in Denver asked about the need to be inspiring and to inspire students and others regarding space, interstellar flight, and our distant human future.   Cameron said we needed to start with kids and that it was important to do so.  He also spoke to the need to make sure our students have and know how to use the skills of critical thought.  The ARM came up and Cameron said it make no natural sense.  He also said we should be getting serious about going to Mars.  During the show he was asked why this was important, going to Mars, human spaceflight, interstellar flight, all of it.  He cited the need to have a humanity insurance policy as from studying the past as he has done in his field, he is all too familiar with species, nations, cultures, and such becoming extinct.  It does happen and space settlement and interstellar human spaceflight are the insurance programs for our survival.  His concluding remarks repeated saying that space colonization was a responsibility, not a luxury.

We welcomed back Dr. Doug Plata to the show to discuss his ideas and concepts for an initial lunar base which he named Lunar Base One.  Follow along with this important website.   http://www.cislunarone.com/lunarbaseone.htm.  Be sure to click on the link in the upper left hand corner to download the Lunar Base One Reference Material. In the first segment of our 2 hour 1 minute discussion, Doug focused on introducing us to his Lunar Base One concept and Lunar Cots.  To follow this discussion, make sure you go to the Lunar Base One website per the above URL as he follows the information on that site for our discussion.  During Doug’s discussion, he took calls and emails from listeners on a wide range of associated topics, questions, and comments.  Listener questions covered telerobotics, wireless power transfer, artificial gravity & the use of a centrifuge at the base, wired power as in missile wire, laser beam power, battery usage, lunar dust, radiation, water, a lunar greenhouse, and check lists re solar panels, propellant, fuel cells, radiation, and more.

In the second segment, Eric called using a cell in Florida to discuss robotics over humans.  Later, Doug was asked if returning to the Moon would divert resources needed for going to Mars, the moons of Mars, or even an asteroid.  Don’t miss his response to this question.  BJohn asked about line of site communications with Earth or if there would be a need for lots of communication satellites.  Doug and John from Ft. Worth had an interesting discussion on several key points, then Doug spoke to lunar tourism, the transportation needs, then I asked him about changing space policy.  Specifically, I asked what he would say before Congress re changing our policy as to why the Moon were he to testify before both House and Senate committees.  Give your ideas on this on the blog because no matter how cool the technology and engineering may be, without a policy to go back to the Moon, most likely nothing will happen.  Rasmus called from Toronto suggesting the use of mylar over a small crater. You don’t want to miss this discussion.  As the show was drawing to a close, Doug spoke about his return to the Moon track at this year’s Space-Access Conference  which will be in Phoenix in late April.  He finished up his discussion talking about artificial gravity, the use of a long arm centrifuge on the Moon running at about a 5.4 RPM by the lunar team.  He also spoke about inflatables and what he learned in his discussions with the University of Maine professor.

Please post your comments/questions on The Space Show blog above.  You can reach Doug at the address on his website or through me.

We welcomed Dr. Edgar Bering  to the show to discuss the “Mars Rover Model Celebration and Competition ” and his undergraduate student balloon projects to study the Northern Lights and more.  During our one segment one hour program, we focused the first half on the Mars Rover Celebration aimed at both elementary and middle school students while in the second part of the segment, we talked about Dr. Bering’s balloon projects and even a possible cubesat to Mars project.  Dr. Bering explained the Mars Rover Model competition which has the students doing a six week Mars course in preparation for their rover mock-ups.  You can learn more about this competition at their website, http://marsrover.phys.uh.edu/about.php.  Dr. Bering took us through the requirements, differences in the competition for the elementary school students compared to the middle school students and he even responded to a question as to how to get a six week Mars curriculum into the school program.  He said the rover categories included a free form model rover made of “stuff” plus a solar power model, and for the older students a radio controlled model made from the parts of an RC model car.  Our guest would asked if the model rover program would work for going to the Moon, not just Mars.  He said yes but don’t miss his full reply.

In the second half of our segment, we talked about his high altitude undergraduate student balloon projects to study the Northern Lights and its effect on the upper atmosphere.  He will be taking his students to Alaska to  see the Northern Lights and to conduct the balloon studies.  He talked about the significant improvements in miniaturizing with the needed electronics, sensors, and cameras, plus today’s high reliability of these components.  He point out that instruments capable of doing the work of today’s instruments would have weighed around 120 lbs. in previous years.  Now they are shooting for a total mass for the instruments of less than 6 lbs for doing meaningful science.  In 1985, the ultra-lute instrument package would have been 50 lbs.  Dr. Bering was asked if his students did cubesat projects and he told us about a possible Mars cubesat project.  He was confident they could get telemetry back from Mars with a cubesat and talked about new antenna improvements.  Toward the end of our discussion I asked if he had any stats on students doing these programs from elementary and middle school and if they went on to careers in space, science, etc.  Don’t miss his response.

We welcomed Dr. Marc Rayman to the program to discuss the Dawn Mission to both Vesta & Ceres.  To find out more about Dawn, visit http://dawn.jpl.nasa.gov.  Also check out Dr. Rayman’s blog The Dawn Journal @ http://dawn.jpl.nasa.gov/mission/journal.asp.   Visit the DS1 site & archives by Dr. Rayman @ http://nmp.jpl.nasa.gov/ds1.   During the first segment of our 91 minute program, Dr. Rayman introduced us to the Dawn mission which first went to Vesta & is now closing in on its second destination, Ceres. We talked about the mission being specifically chosen to visit both Vesta & Ceres & that Vesta data is still undergoing analysis.  Dr. Rayman described Vesta’s Rheasilvia Crater 300 miles in diameter formed by an impact about one billion years ago.  We also talked about Vesta meteorites on Earth.  Dwayne called regarding competing theories about Ceres, planets having changed positions at one time, & Dawn mission limitations.  Perry wanted to know what information the team most wanted to get from Ceres. Dr. Rayman said they wanted to know basics such as what it looks like, what it was made of, ice, etc.  Other listeners wanted to know about Ceres compared to Mars access.  Here, Dr. Rayman had much to say as the subject came up again in the second segment.  Doug wanted to know about the large bright spot on Ceres plus other questions.

 

In the second segment, Dr. Rayman told us about his Dawn Journal (blog) per the above URL.  I asked our guest if he thought of Dawn & other science missions as competitive with human spaceflight missions.  Don’t miss his reply as I believe it was very special. BJohn sent several emails asking for Dr. Rayman’s favorite targets, especially for future missions. He also asked about using nuclear power rather than solar.  Our guest described the solar arrays & why solar was chosen for Dawn.  Ion propulsion came up & was a major discussion topic for the balance of our program.  Dr. Rayman described how ion propulsion worked, why it used a slow but steady acceleration, & its advantages over chemical propulsion.  Matt asked about RTG development for future missions .  Doug sent us another question based on the low Ceres gravity & landing on Ceres to pre-position supplies in advance of a crew.  Our guest pointed out it was far more complicated than Doug implied given that the Ceres orbit was tipped more than 10 degrees from the ecliptic.  Make sure you hear this explanation.  Among the many questions Matt asked, he wanted to know about the German component of the Dawn mission.  As we approached the end of our show, Dr. Rayman gave us a preview of what to expect as we get very close to Ceres, gradually getting as low as Earth & ISS.

John Batchelor and I welcomed Dr. Ashwin Vasavada to Hotel Mars to discuss the latest findings announced by NASA in December 2013 regarding methane discoveries, organics in rocks, and indications that there had been flowing water on Mars, perhaps during the first billion years of Mars. As we learned, the first billion Martian years were likely to have been more supportive of microbial life than later times on Mars for a variety of reasons which our guest discussed during our 20 minute Hotel Mars segment. During our two part segment, we talked about free flowing water on Mars, the Mars methane as detected by Curiosity, and the organics found in Cumberland Rock. We asked Dr. Vasavada, the new Chief Scientist for MSL and Curiosity, many questions pertaining to these three end of the year 2013 NASA announcements and our guest guided us through the science, discoveries, plus he responded well to our inquiries. This is a Hotel Mars segment you will not want to miss! Note that the two parts of this segment are joined together as I eliminated the break.

 We welcomed Dr. Andrew Rader to the show to discuss his aerospace engineering lectures and other material on his website, http://www.andrew-rader.com as well as his YouTube channel.  You can access all his material, his YouTube channel and his book through his website.  During our one segment one hour discussion, Andrew talked about his Mars cooking video regarding his eating bugs.  We had quite the discussion about this.  Crickets anyone?  Next, we talked about going to Mars and he introduced us to his YouTube channel which has 74 videos and more on it.  His aerospace engineering class lectures are there too and very popular with students, especially those wanting to see if aerospace engineering might be the path for their studies.   Joe asked our first email question about the necessity for a flyby or human orbital mission of Mars prior to humans landing on Mars.  We then discussed Mars, why a one way mission, and the Moon vs. Mars.  Other topics included spacecraft and rockets in general, Apollo, robotic missions, and more about human spaceflight.  At one point I asked Andrew how he stated the purpose for our going into space.  Bethany asked Andrew to explain what was meant by the term ecliptic. In response, Andrew offered a short explanation using basic orbital mechanics.  We talked about several specific videos on his YouTube channel including the Sagan Darkness video, the Ambien Space Music videos and the Star Trek and Darth Vader videos.  I asked him what he liked best and he said it was systems engineering because he liked putting and seeing how everything works together.  Human factors came up and he made an interesting statement to the effect that if we require 21st century medical care on our space missions, the technology itself may be an impediment to the mission.  We talked about the multi-systems failure risk being the biggest risk in his opinion and the steps taken to mitigate this risk.  I also asked about crew failure risks including medical and psychological issues.  Andrew offered us interesting observations about crew risks and issues so don’t miss what he said.  As the show was drawing to a close, we talked about his introduction to spacecraft videos.

Welcome to our first Open Lines show for 2015.  During the first segment of our two hour program, I made a few topic suggestions as usual.  In my suggestions, I asked for listener ideas for both debate and webinar topics plus guests to invite for the suggested programming.  In the second segment listeners sent in many good suggestions but for those of you listening on archives, please send in more.  Sending in guest suggestions for the debate and webinar topics would be very helpful.  The first call was from John in Florida.  He wanted to talk about several topics including the SpaceX effort to land the first stage on the barge.  He also talked about Blue Atlas, Orion, Apollo, the NASA risk averseness and more.  Dr. Lurio called next to tell us where we could see photos of the barge after the crash landing of the first stage.  He also commented on news relating to Blue Origin & the Elon Musk interview on Bloomberg.com.

In the second segment, John called from Ft. Worth, commented on my comments re the email I read about the movie “The Principle” and his thoughts on doing a show with the people behind the movie.  John also asked about the SpaceX refurbishment plans for the first stage once they recover it.  Furthermore, he talked about Elon’s plan for satellites and more.  He asked if SpaceX might be overextending with all the ventures and projects it and Elon are involved in or announcing.  Several listeners sent in debate and webinar topic suggestions including nuclear propulsion, Is Mars The Goal, Mars vs. Europa, National Competition versus International Cooperation, Space Shuttle debates and more.  Pooley called in and we talked about Microlaunchers and other issues.

We welcomed back Professor Haym Benaroya to take us through the steps necessary to establish a lunar settlement, the challenges, our initial TRL and more.  During the first segment of our 97 minute program, Dr. Benaroya advocated for the Moon before Mars and stated his reasons which he repeated several times during the interview.  We talked about the size of the launch vehicle needed for establishing a lunar outpost and then launch costs came up, especially with regards to the proposed Falcon Heavy.  Our guest was asked about one way lunar missions which he did not think possible anytime soon and here he referenced the history of psychological problems encountered by many in spaceflight.  At this point, let me say that we received a few cell phone calls with unacceptable audio on their phone.  Since Dr. Benaroya could get most of what the caller was saying (I could not), I tolerated the poor quality calls for as long as possible and then terminated them.  Listeners, please, use a quality phone line to call the show.  If your call is garbled, I will disconnect you.  Doug called from S. California to talk about consumables being the largest part of the mass. He talked about reducing the mass by using lunar water, recycling, etc.  Dr. Benaroya explained that would not happen right away so for the early stages of an outpost, mass from Earth will be the name of the game. Other topics in this segment included the use of lunar robotics, TRLs today and for the future, & incremental engineering. Dr. Bill Rowe called to talk about medical issues such a heart attack in space, mall absorption of drugs in the GI system, & the need for subcutaneous pharmaceutical administration in space.  Lunar dust was an issue & John from Ft. Worth called to ask our guest to talk about the dust & why it was so challenging to deal with re astronauts and equipment.

In the second segment, we talked about the role of structural and civil engineers, how they go about defining the environment they will be working with and more.  All of this was in response to the question of how does one actually go about building a lunar outpost given one does not exist.  Haym talked about radiation, microgravity and the likelihood that the first crews would be there for six month and return and live in a pressurized cylinder of some sort.  Lunar manufacturing was a discussion topic as was ISRU, 3D printing & the maintenance and repair of lunar equipment.  Haym responded to a question about possible Moon-Mars synergy.  Doug email in questions about inflatable structures and Haym talked about the need to make them rigid.  Doug also asked about duplicating 1/6th g here on Earth and the use of a short arm centrifuge.  Near the end of the show, Haym said the barriers were really political decisions, not the engineering, physics, medical, etc.  He also said it would a long time to build out a lunar outpost and we should be patient.
