We welcomed Dr. Paul Spudis back to the program for a 2015 space year in review. During the first segment of our 1 hour 31 minute discussion, we covered much ground reviewing key events of 2015 including European, Russian, & Chinese space accomplishments & missions. Dr. Spudis got several emails on a wide range of topics from space advocate rhetoric to Orion, CST 100, Dragon V2 and more. Regarding advocate mission plans and projects, he said the technology people talk about and want to use in their various space mission designs does not really exist. He used going to the Moon to harvest water ice for water and fuel as an example of where we are today. That said, he indicated that there are only so many wants to do certain types of space projects so it was likely that which advocates called for could end up in actual mission plans and real projects. Budget issues were also discussed as well in this segment. Listener Christa asked if the return to the Moon and cislunar development will become a future policy priority. Dr. Spudis had much to say on this topic so don’t miss it. This included the possible impact of the 2016 presidential election on space policy. Jeff in Boston inquired about the aging process and other human factors as challenges/obstacles to doing BLEO projects. Dr. Spudis offered us an interesting perspective on the human factors issues. Jack in Portland inquired about our guest’s views on asteroid mining and the language used in the new commercial space law recently signed b the president. Our guest shared his views with us on these issues. We talked public-private partnerships and government procurement. Kim called from Mexico to inquire about the Lalande Crater on the Moon & the cracks or fissures seen in the photos, plus impact melt and more. She also talked about young and old craters which Paul defined for us upon my request. A young crater would be less than a billion years old! Near the end of the segment Paul talked about the challenges in closing a business case for going to the Moon at this time, plus the proper role for government in this situation. Sandra asked about the lunar space elevator.

In the second segment, Kim called back to inquire some more about Lalande crater, thorium bright spots, and more. BJohn emailed in asking about lunar landers, then Rodney brought up space settlement. Paul had interesting comments on space settlement you will wan to hear. A good portion of the second segment was spent on Mars. Back to the budget, he said the challenge was to do more in the most efficient ways possible while reducing the need for more funding. The Mars-Moon debate came up again with Paul explaining why returning to the Moon before going to Mars was important Solar power for missions and habitats was discussed along wit ISRU usage. Don’t forget to reach Paul’s article on Air and Space about the asteroid mining section in the Commercial Space Law just signed into reality by President Obama. See Paul’s writings at www.airspacemag.com/author/paul-d-spudis/?no-ist as well as at www.spudislunarresources.com.

We welcomed Jon Goff back to the show for Altius Space-Machine updates and more. Make sure you follow along with us at his website, www.altius-space.com. During the first segment of our 90 minute discussion, Jon brought us up on Altius activities since his last time as a guest on the show in March 2013. We discussed the projects listed on his website home page, Prospector, Lisa, the Robotic Manipulator, and EMBARC-2. I asked him for updates on Sticky Boom and how the new projects related to Sticky Boom. As you will hear, Jon and his team are engaged in several innovative projects. Listeners wanted to ask Jon about fuel depots so that topic contributed to both our first and second segments. Later in the first segment, Doug called to compare the Falcon Heavy with the use of depots, suggesting the Falcon Heavy would be more cost effective to LEO than using depots. This was an interesting discussion on this topic so don’t miss it. ISRU was discussed as was aerobraking coming back from the Moon.

In the second segment, Joe had the lead off question asking Jon if they were planning to engage in cubesats and Earth-imaging. Jon’s reply included a discussion of his Big Vision concept for his company and how he wants to contribute to the space industry. Carl in Tucson asked Jon about using Sticky Boom or one of other concepts to get rid of LEO space debris. Following that discussion, Jon told us about his Private Placement plans for his MAGE (Mechanical Assistant for Glovebox Experiments) project, where Altius is trying to adapt some COTS robotics and 3d vision solutions for use inside the Microgravity Science Glovebox on the ISS, and on the 3DOF STEM Arm testbed that they wanted to use for testing various Sticky Boom capture mechanisms on an air-bearing table. Another listener asked Jon about building launch vehicles for cubesats. Wayne asked about SBIRs, exceptions for those from outside the U.S. and foreign government funds for companies like Altius. As we were nearing an end to our program, I asked Jon for his five year forecast for the cubesat industry, then the same for his company. Jon had much to say on this topic, including talking about ADS-B ground stations, SpaceX, One Web, smallsats beyond LEO into MEO and GEO. As we were ending, Harry asked how independent Jon was from NASA policy, the administrator, etc. We concluded our discussion with Jon mentioning possible future hiring needs and his thoughts on having started up his own business five years ago.

Please post your comments/questions on TSS blog above. You can reach Jon through his website, me, or the private placement address he gave out on air.

We welcomed Dr. Doug Plata back as our guest to discuss his paper which is on TSS blog for your perusal, “Achieving Early Earth Independence Through ISRU and Sufficient Supply.  During the first segment of our 1 hou 45 minute program, Doug told us the genesis of his ideas and concepts culminating in his submitting his paper to the NASA Challenge InnoCentive Challenge (www.innocentive.com/ar/challenge/9933746).  After referencing the NASA Challenge, Doug started describing his ideas in detail.  Much of what he described he said was summarized in the Introduction of his paper.  We talked about both the Moon and Mars but Doug explained that the competition was focused on Mars so he also focused on Mars though he still supports the Moon and cislunar development as the rational and initial starting points.   Issues he discussed included supplies, types of potential habitats, the definition of and clarifications for mass independence including defining both self-sufficient and self-sustaining.  He also brought up the earth return option and more.  BJohn sent in several questions but his initial one asking about becoming 90% Earth independent led to a most interesting discussion.  While Doug’s paper does not have page numbers, check out Table 3, “Estimated Equivalent Mass Independence.  Doug took us through the critical numbers and his analysis so don’t miss this important discussion.

 

In the second segment, Doug suggested three rationales for the settlement.  One was to push technologies needed for sustainable living in space.  The second was the big one according to his perspective and focused on reducing the resupply costs for the settlement.  The third one was also big and focused on assuring survival of the human species.  He discussed each rational in detail.  As part of the discussion, he referenced a space settlement as an insurance policy for humans, he talked about the earth return option, radiation, GCRs,  and more.  He also showed that by leaving the crew on Mars for an extra year, the mission would be less costly.  Listen to his discussion about this and see if you concur with him.  Doug was asked about the previous program with Al Globus and LEO settlements, especially over the equator.  He said that such settlements, while potentially interesting, cannot be self-sufficient or Earth independent and his focus was on gaining Earth independence.  Again, don’t miss this discussion.  Gravity, artificial gravity and spin rates were discussed as was the concept of self-sustaining versus self-sufficient for a colony.   Doug advocated for using the word colony rather than settlement but I took issue with that, especially if one hopes to communicate with people including Congress outside the space industry.  As the show was ending, Paula asked Doug about the fact that space settlers may not want to achieve Earth independence and it seemed his work was formulated around the assumption that everyone wanted Earth independence ASAP.  This was a great last question and discussion.  Doug provided a good summary of today’s discussion as we closed the show.

We welcomed Dr. Erik Seedhouse back to the show for a variety of timely discussion topics. During the first segment of our 1 hour 37 minute program, Erik started out making comparisons with past polar exploration and going to Mars. He also said that going to Mars anytime in the foreseeable future would be a survival trip. We talked about Erik’s books on Virgin Galactic, Polar Exploration and Mars which will soon be released, and additional books on Dragon, Mars One, Mars via the Moon, and XCOR, all to be released over the coming months. Erik then spoke about his ISDC talk re comparing polar exploration to going to Mars and commented on the speaker following him, Dr. Logan (he was not sure of the first name but we think it was our friend, Dr. Jim Logan). He talked about radiation shielding and water per what Dr. Logan had to say including the need for 10 meters of water shielding to equal the protection here on Earth. Erik had much to say about radiation and shielding which prompted multiple emails from Dr. Doug in S. California seeking clarification and adding to Erik’s comments. I read all of Doug’s radiation themed emails throughout the first and second segment of today’s program. Don’t miss Erik’s conclusions regarding the radiation risks and shielding needs for a Mars mission, how astronauts would live and work on Mars as well as the Moon. Erik next talked about Virgin Galactic and XCOR saying he thought XCOR would be the first to fly commercially. When asked about the biggest passenger risk on a suborbital flight, Erik said it would be the cardio-vascular risks. Erik got questions regarding SpaceX, Elon Musk, and the Mars Colonial Transporter. He again stressed the way to go to Mars was via the Moon and that would be his preferred space policy. He also put forth his Mars simulation study plan. Don’t miss it, I think it’s a good one.

In the second segment, John from Florida called to comment on delays and how long commercial suborbital flight was taking since the success of Spaceship 1. John seemed to compare the lack of progress with suborbital flight to how much progress was made with aviation and in particular jet travel. I took the first pass at responding to him, then Erik offered his comments. What do you think? Let us know on the blog. Erik was then asked about other human factor issues than radiation. Dr. Seedhouse went through a laundry list of health risks and concerns for astronauts in deep space and on long duration spaceflight. He was then asked about the regulatory regime for suborbital space, then he wanted to define space given Virgin Galactic may not flight beyond 50km which is not space. Don’t miss what he had to say about this and the overall health risks for astronauts in deep space. Near the end of the show, Erik addressed space settlement. He said it would be a natural expansion and would happen automatically with returning to the Moon and going to Mars via the Moon. In his concluding comments, he suggested that advocates and space enthusiasts need to adjust expectations and understand the technology involved because its harder and more costly to do things in space, including suborbital space, than originally thought and expected.

We welcomed Tom Olson back to the show for his annual end of the year review show for the space year at hand, 2014.  During the first segment of our last program for 2014, I asked Tom for positive memorable events in 2014 .  Tom came well prepared for this question.  Do you have the same memorable events list or a different one?  Let us know on the blog.  As Tom was going through his list of memorable positive events and developments for 2014, we took some email questions about Blue Atlas, the Delta IV and human rating it, and of course ULA.  Another listener wanted to know what Tom thought of the idea of a prize for an on orbiting demo propellant depot and fuel transfer.  Toward the end of the first segment, Dr. Lurio called in and talked about fuel depots, markets for them, NASA and more. We also talked about Virgin Galactic and SpaceShip2 plus what may be forthcoming from the NTSB report when it becomes available.  Antares was also discussed before the break.

In the second segment, Jeff from Tucson called in about a possible Netscape Moment.  Tom did not think much of a Netscape Moment, instead he talked about the concept of space scalable.  I got in on the discussion as did others and this led us to our discussing reusability with SpaceX and would it be a game changer.  Later in the segment, more was said about the Delta IV, ULA, Atlas and even SLS.  For 2015, Tom talked about Bigelow Aerospace getting their modules up to the ISS.  He also talked about Dragon V2 and Falcon Heavy.  In addition, Tom mentioned Power Beaming test for SSP in space beaming power from point to point but in space.  Of course SLS and Orion came up. Tom is not supportive of it, Dr. Lurio called in who is not supportive of it and holding up the fort for it was our friend SLS John.  The latter part of the show was an ongoing give and take with Lurio, Tom and SLS John highly engaged in a back and forth but as you will hear, there were no winners.  Tom and I did a bit of reminiscing because we go back with one another for more than a decade.  We wished everyone a very Happy New Year and a great 2015.  And remember, “y’all come back for more in 2015!”

We welcomed Dr. Richard Binzel to the show to discuss asteroids, the NASA ARM, and completing the NEO survey.  During the program, Dr. Binzel referenced two items. The first, his article in Nature is at http://www.nature.com/news/human-spaceflight-find-asteroids-to-get-to-mars-1.16216.  The National Academies study he mentioned is at http://www.nap.edu/openbook.php?record_id=12842.  During the first segment of our 90 minute program, Dr. Binzel introduced us to the asteroid topic, the asteroid belt, 1 km size asteroids and he responded to my questions about Asteroid UR 116.  Our guest then addressed the NASA ARM and explained why he is not supportive of it.  He referenced his above article in Nature on the subject.  You can get this article at the above URL.  He talked about visiting asteroids in their natural orbit rather than bringing a small one back to orbit the Moon.  He had much to say that was positive about visiting an asteroid, explaining as well why such a visit is on the path to HSF to Mars.  He then explained his program for completing the NEO survey which is to find and catalog specific NEOs.  Listeners asked him many questions including if radar was a good tool for finding asteroids.  He said no because it uses a very narrow beam.  He also said that were the NEO survey completed, most of the most accessible destinations for HSF and science missions would be cataloged and would open up space.  He goes into detail on this near the end of our show.  We talked about international NEO survey and planetary defense issues.  While the U.S. remains the leader, ESA is doing more and more.  He also said that rather than spending just $20 million on asteroid detection, we should be spending $200 million annually until the survey is completed.  Joe in Houston sent in a series of questions starting in this segment and ending when the show ended.  His questions, all of which were read on air, centered around ways to bring an asteroid into orbit around the Moon.  Listen to what our guest had to say about his multiple suggestions/questions.  Professor Binzel clearly likes and welcomes fresh ideas & also insists on running the numbers and doing the trade analysis.  John called from Ft. Worth asking about the size of an asteroid that should be getting our attention.  Time lines were brought up as we need time for the best way to deflect an asteroid on an Earth collision trajectory.  Near the end of the segment, our guest talked about a NASA Grand Challenge Mission around asteroid detection and intervention methods starting first with the survey, the concepts on how best to deflect an asteroid and then about 30 years out, a contest on an ISRU test for resource extraction on an asteroid.

 

In the second segment, Doug sent in multiple questions, then after I asked our guest a few of them, he called in to talk about some of the other questions on his list.  Doug asked Dr. Binzel good questions so listen carefully to their discussion.  One thing of note was that the size of an asteroid presenting the greatest risk to Earth is 140 meters.  Joe continued emailing evolutions of his initial three questions from the first segment.  Asteroid ISRU was again discussed in this segment, so was the likelihood of a comet impact on Earth, & a privately funded mission to complete the NEO survey was also discussed. As the program was ending, Dr. Binzel spoke to the issue of the NEO survey being a game changer and opening the gateway to our future.  This is important so do listen to his comments on this issue.

 

Please post your comments/questions on The Space Show blog above.  You can reach Dr. Binzel through me or his MIT faculty page.

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.

We welcomed both Dr. John Jurist and Dr. Jim Logan back to the show to discuss spacewalks (EVAs), spacesuits, human missions to the Moon and Mars, to the Martian Moon Deimos, the newly created Space Enterprise Institute, & the new Aquarius Reusable Human Spaceflight water based launch vehicle.  During the first segment of our 2 hour 5 minute program, our guests started talking about EVAs.  Early in the discussion, Dr. Logan provided us with important & interesting statistics regarding EVAs, then we discussed the challenges with them and spacesuits.  We talked at length about the difference in EVAs and spacesuits for the Moon, LEO, asteroids, & Mars.  We also talked economics for spacesuits given the need for a specific spacesuit depending on the destination/mission.  We talked about new designs for one size fits all & for mitigating dust problems.  Jim talked about the medical complications regarding both lunar and Martian dust.  Our guests then suggested that EVAs will likely be phased out for robotic missions.  Doug asked several questions about this via email.  Also, Jim suggested that EVAs will evolve to the concept of Forward Deployed Humans in the Loop for Telerobotic Operations.  This concept was discussed several times throughout our program.

In our second segment, Jim started with an announcement about the Space Enterprise Institute (SEI).  When it goes live in the next week or so, I will announce it on the show so you can follow it  He explained SEI, its purpose & goals.  He then talked about the concept that both Jim and Dan Adamo have developed over the past few years, Aquarius which is a reusable water-based interplanetary HSF transport.  As soon as the SEI website is online, listeners will be able to download their peer reviewed paper for free.  During this segment, Jim talked about Aquarius, John added in some details, we talked about the need for nuclear electric propulsion and why, plus the role of water with this launcher.  Both our guests explained the advantages of Deimos for the early missions, plus the return shielding and reusability as the return goes to a lunar orbit using existing water.  Radiation shielding was talked about, including the needed water and needed Radiation Protection (RP) levels.  John pointed out one advantage of Aquarius was the use of an open loop life support system.  John in Ft. Worth called about the temperatures that Jim said were needed.  Jim explained the need for 3,000 degrees C.  Both guests offered closing comments about EVAs & the direction we might be heading toward the forward deployed humans concept.  Both guests said the telerobotic concepts discussed would reduce risks, timelines, & overall mission costs.

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.

Please post your comments/questions on TSS blog.  You can reach Doug through me or his lunar cots page.

We welcomed Dr. Wendell Mendell back to the show for this two hour discussion (no break) about his 50 years at NASA JSC, lunar bases, commercial space, return to the Moon, the value of the Moon, our space program, space advocacy, commercial space, and lots more.  Dr. Mendell came to work at JSC in 1963 &will be retiring at the end of this year, culminating 50 years at JSC.  During our discussion, Dr. Mendell used lots of stories from his NASA and lunar base work experience to illustrate issues with space policy, NASA, our Congress, and space advocacy, & advanced technology.  Listeners had lots of specific questions for Wendell about lunar bases, water on the Moon and its commercial exploitation, commercial lunar programs, and NASA having a lunar program which Dr. Mendell said it did not.  Dr. Mendell spoke to some of the NASA organizational issues, congressional micromanagement issues and problems, and the nation’s overall economic problems as a reason for not doing this or that in space.  He cited such economic problems as a rational excuse for not doing something meaningful in space in almost every year of his 50 years of NASA experience. The same for threatened, proposed, or even real NASA budget cuts.  Later in the segment when caller Doug called in with his lunar water and development ideas, Dr. Mendell pointed to conflicting LCROSS analysis as to water being on the Moon. Russian instruments do not say the same thing as the Los Alamos instruments and he said this was & still is a hotly debated topic in the lunar community.  As Doug continued talking about his plan, Dr. Mendell backed him up, took him step by step through the process of accomplishing his many goals. This turned out to be a very valuable instructional discussion that all of us can and should benefit from.  Make sure you hear how Wendell breaks down Doug’s points to show the complexities and challenges of each incremental step in what Doug was proposing.  Our guest even showed Doug where some of his steps needed commercial technogly which does not exist! Doug’s rocket of choice is the Falcon Heavy, a rocket which does not yet exist, nor does it have real numbers behind it.  Wendell used this discussion to distinguish true believers from investor and commercial analysts.  He then said when the believer is also able to bring his own money to the venture, things can get done and he cited SpaceX as an example.  Later Doug asked by email if NASA could help private companies develop cislunar transportation as they have helped private companies provide launch services to LEO/GEO. The simple answer was yes but make sure you hear Dr. Mendell’s complete answer to this question.  Another issue discussed was the needed timeline to do a human Moon mission. Wendell described the times of Apollo as compared to the times of NASA today.  We talked about the importance of a better and different NASA and RTM story and again, Dr. Mendell illustrated his points with stories from his past experience.  Spanning 50 years of history and experience was not easy to do in even a two hour Space Show program. As you listen to the program, you will hear many more subjects, stories, and issues discussed than stated in this summary.  In the end, I believe NASA, our nation, and the effort to develop space has been served incredibly well by Dr. Wendell Mendell and his creativity, his drive, his analysis, his commitment, and his work will be genuinely missed by all.  The Space Show wishes Wendell all the best for his coming retirement, gives him a hearty THANK YOU for his service, and we will remain in contact with him and hope to have him back with us at a future time.
