John Batchelor and I did a quick 2015 year in review. We both agreed that the latest Falcon 9 launch by SpaceX was a potential game changer with the success of their flyback booster landing upright at the Cape. We also talked about the rest of this particular SpaceX mission which was just as impressive. For planetary science, we selected several mission for our 2015 best including New Horizons, Dawn, Akatsuki which started orbiting Venus after being lost for five years, and the Japanese Hayabusa 1 and 2 missions,. We commented that we were disappointed in the suborbital industry progress other than for Blue Origin and their recent successful test flight with their rocket return to the pad. John liked the European Rosetta Mission for Comet 67P and specifically the Philae lander. We summarized our short discussion by wishing everyone a very Merry Christmas and Happy New Year, plus we look forward to 2016 being another exciting year for space.

We welcomed back Dr. Chris Impey for a one hour one segment discussion about his two recent books, “Dreams of Other Worlds: The Amazing Story of Unmanned Space Exploration,” and his newer book “Beyond: Our Future in Space.” We started our discussion with Dr. Impey describing “Dreams of Other Worlds” which describes 11 unmanned space missions that have made a difference in our understanding of distant worlds. We focused on a few of the 11 missions including Viking, Cassini, Voyager, & the WMAP mission. I asked Dr. Impey what would have been included had the book been written later. The Dawn Mission would have made it, so would the Kepler Space Telescope, New Horizons, Curiosity, and probably others. We then switched to the use of ground based telescopes and here Dr. Impey talked about how many of the telescopes are being repurposed for a new life doing different types of observation astronomy. Dr. Impey was asked about his favorite missions. He mentioned Viking and the WMAP microwave telescope mission and this led to his talking about The Big Bang, dark matter, and dark energy. I asked Chris about the recent article in The Economist about the two Chicago area scientists proposing a new theory on dark matter. Chris had read the article and had some interesting commentary on it and the proposed theory. Robert sent in an email asking our guest why there have been no life detection experiments on the NASA and other planetary missions. This sparked a good conversation on the subject which you do not want to miss. Chris proposed a very plausible reason why no suck experiments have been carried out but let us know what you think by posting on the blog. Another topic discussed was planetary protection. Linda from Austin asked our guest about the UofA astronomy and cosmology programs and students, then Bill asked our guest if he had read “The Martian” or seen the movie. Chris had both read the book and seen the movie which we discussed for several minutes. Don’t miss this discussion as Dr. Impey made some interesting points about both the book and the movie and the plausibility of the story line including the initial dust storm which caused the problems for The Martian. Before the end of the program, Chris fielded some questions about future missions. We addressed the Europa Clipper mission but he said many may be disappointed for what was not being included on the mission so again listen to what he had to say. He suggested a Titan mission would be interesting. In his book “Beyond” Our Future In Space,” Dr. Impey addressed the new commercial missions & human spaceflight. Chris guided us through all sorts of possibilities for future human spaceflight. Nuclear propulsion came up with Dr. Impey having much to say about how beneficial it would be if we had it though it was still futuristic. We spoke of advanced technology & the Decadal Survey and its impact on the type of science projects that get undertaken due to funding. Will sent in a note asking about the recent article about Elon Musk wanting to get to Mars in 10-15 years given the various risks Earth faced, including extremism. Dr. Impey also said it was probably unrealistic to think that one could have a $500k ticket price for Mars, another part of the Elon Musk article. Dr. Impey offered us good summary comments so don’t miss them. The last question dealt with a possible science backlash and referenced the following Huffington Post article: www.huffingtonpost.com/entry/solar-farm-suck-up-the-sun_566e9aeee4b0e292150e5d66.

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. While there, check out his “Close but no Cigar” article we discussed on air (www.spudislunarresources.com/blog/the-new-space-resources-law-close-but-no-cigar).

We welcomed Michelle Cadieux to the show to discuss the space startup community, cubesat startups, space research, and much more. I suggest you listen with pen and paper as our guest mentioned several companies and resources that you might want to contact and use. During the first segment of our 1 hour 21 minute program, Ms. Cadieux started out by talking about the Minneapolis based Robotics Alley Conference (www.roboticalley.org). Michelle’s team placed in the investment and innovation category of this conference with a space project which she described on the show. As we learned, her team’s project was the only space project at the conference which caters to the general robotic science and engineering fields. Michelle then discussed the SpaceWorkBench (https://spaceworkbench.wordpress.com/). From this point forward, Michelle offered up organizations and companies doing interesting tings in the space startup community or reporting on it. We talked about cubesat opportunities and options, the possibility of future deep space cubesat, then the subject of the lunar space elevator came up. Michelle mentioned the company Lunar Lift Alliance. The lunar space elevator was mentioned many more times in this segment as well as the second segment of our program. The next topic focused on hackathons around the country. We talked about their market, what they do, crowd funding programs plus Michelle mentioned specific companies and resources for interested listeners. Later in the segment, I asked our guest about human spaceflight opportunities and we talked about space tourism.

In the second segment, Michelle told us about her Facebook site which lists & tells us about startup, hackathon-like and similar events on a national basis. You can find her site at www.facebook.com/creativecommunications?_rdr=p. One event that stood out was the Las Vegas AT&T Development Program with its cash prizes. Todd in San Diego asked our guest about the regulatory environment for the space startups. Next, we briefly discussed asteroid mining with our guest mentioning asteroid valuations. Space law came up, then I asked Michelle about relationships with the hackathon and startup community with the larger aerospace companies such as SpaceX, ULA, etc. Michelle mentioned that many of these organizations sponsor events in this entrepreneurial community. During the remainder of the second segment, cubesats were again discussed along with people’s interest in getting out of LEO and my asking Michelle if she wanted to go to space. Tim called with questions about the lunar space elevator and possibly a Martian space elevator. As the show was about to end, business plan competitions were brought up along with a focus on the need for innovation.

Please post your comments/questions on TSS blog above. You can reach our guest through me or through her Facebook site.

We welcomed back to the program Joe Carroll to update us on his work with artificial and partial gravity, plus his thoughtful considerations for what comes next for human spaceflight. I have uploaded three papers of Joe to The Space Show blog for today’s program. He does refer to these papers and presentations during the show so be sure to follow along by viewing them on the blog. During the first segment of our 1 hour 41 minute program, Joe said he preferred using the term partial gravity to artificial gravity. He talked 1 g issues, tests that can be done on the ground and the need to learn about gravity limitations for humans through ISS research. Centrifuge spin rates were a significant discussion topic in this segment. Here, he referred us to Appendix A page 8 for a two page discussion on early research on this subject. See his paper titled “Partial Gravity Biology Research Paper for Space 2015 Final” on TSS blog. Joe referred several times to the Twins & one year cosmonaut/astronaut study underway on the ISS, plus the Gemini 7 mission which answered several important microgravity questions. Later, Joe suggested we look at the chart on the third slide of his Power Point where he showed the gravity factor of major bodies in our solar system. This is an interesting discussion, don’t miss it. It also pointed to the importance of knowing the gravity prescription for Moon-Mars as it covers most of the solar system gravity ranges. Doug sent in an email about spin rates as high as 24 rpm. Don’t miss how Joe responded to Doug who then sent in a clarification email about upright exercise in a short-arm centrifuge. Again, don’t miss Joe’s reply. At this point, Joe started raising questions about why Mars, asking what were the economic reasons. He referenced our National Space Policy from 2010. Joe suggested the direction of the manned program was confusing at best. He talked about the remaining residual from the Apollo momentum and the Outer Space Treaty impact on future human spaceflight. BJohn emailed in about artificial gravity experiments with cubesats.

In the second segment, Tim asked several questions including one about using weighted clothing to offset microgravity. The subject of radiation exposure came up and here, Joe talked about the side effects of “fixes” which may cause even more problems than just the original problem being mitigated. He again referenced the Twin and cosmonaut/astronaut studies on the ISS now underway. Doug called regarding my earlier comments where I reference a past show in which many listeners did not think we needed to know the gravity prescription. Doug corrected what I said about his position but Joe thought there were solid advantages to know the gravity RX and to do so in LEO. You will find this discussion to be very interesting. In the latter part of this segment, we talked about being serious about humans going BLEO if we are not serious about finding out the gravity RX for humans. Safety came up and here Joe had much to say about the approaches regarding Orion and Dragon. Jack emailed in about our lack of seriousness on HSF BELO since we are not trying to learn the human gravity RX for long duration spaceflight or settlement. Joe went so far as to suggest convening a panel discussion to open up the discussion channels on what should be next for HSF. He listed potential participants but also invited listeners to send in to me or post on the blog their suggestions for participants. He said this was the perfect time for such a discussion as we entered the last year of the current administration. Doug sent in the final email saying that the challenge was more about how we go about deciding who’s vision gets the funding, suggesting this challenge took precedent over figuring out the next vision for HSF.

Please post your comments/questions on TSS blog above. You can reach Joe through me.  The papers Joe referenced can be found below.

We welcomed Charlie Chafer back to the program to discuss commercial space, the Celestis space memorial services and flights, plus much more. During the first segment of our 88 minute program, Charlie started out by providing an overview of the commercial space history since he played a huge role in its start decades ago. For example, he talked about the fist ever commercial launch that was done by his company, the regulatory and permit process back then, and how the industry has evolved since those early days. It’s a most interesting discussion with one of the major founders of the commercial space industry. We then changed topic to talk about the space memorial services and how this industry has changed since 1994 when Charlie co-founded Celestis. As for today, Celestis has a global customer space offering several categories of space memorial services, all of which are described on the Celestis website, www.celestis.com. There launches are far more routine today with more launch vehicle availability. Regarding the lunar service, he talked about sending Eugene Shoemaker’s remains to the Moon, then later in the second segment, he talked about the commercial space significance of having done this. Celestis offers four services including Earth Rise which is suborbital, an orbital service known as Earth Orbit or Earth view, the Lunar Service, and the Voyager Service which is a deep space mission. He described each service but also he talked at length as to how Celestis carries out a memorial spaceflight starting with advance work before the launch, tours of the launch pad, a special Celestial memorial service, and the launch. Listeners asked Charlie several questions about the service including listener Judy who had seen rocket launches before and wondered how those attending a memorial service launch viewed watching a rocket launch. Before the segment ended, Charlie was asked about pet memorial services. Celestis offers the Celestis Pets Memorial service. Check out www.celestispets.com for more information on this service.

In the second segment, we focused on commercial space, customers, markets, commercial waves and more. Our guest pointed out some thoughts that might suggest a possible commercial space “bubble” ahead. He also talked about & described the three waves of commercial space history. Charlie talked about his interest in opening up commercial markets in the space weather field and we talked about the value of data as a product. Regarding SSP which he mentioned, he said it has not developed but may do so down the road in the future. The same for pharmaceuticals and other energy related possibilities. We talked about the many commercial applications, customers, and uses for GPS, truly a successful commercial space field and product. A listener asked Charlie how he thought the commercial markets might change if we had low cost commercial launches available to go to private, commercial space stations instead of the ISS. Jake wanted to know Charlie’s thoughts on SLS and Orion. I asked Charlie if he saw any possibilities for human spaceflight commercial products or services in the near to intermediate term. Other points of interest included space tourism and adventure travel, especially for orbital flight which might be 15-17 years in the future. A listener then asked Charlie about the lunar memorial service and if you had to be a special person to get permission to be have remains sent to the Moon. Charlie described the process they went through with Gene Shoemaker and why they did it the way they did it because they wanted to set a commercial space precedent for the future. Among his closing comments, he said space is hard and take action to follow your dreams.

We welcomed back Debra Facktor Lepore to this special one hour one segment program in which we discussed numerous space industry topics.  We started out getting an historical overview of Ball Aerospace, including our learning about some of their new projects with S. Korea and new technologies.  We did a 135  year overview in just a few minutes.  The company really does have a fascinating and most interesting history, including the Ball jars dating back to the 1880s when the company started.  The aerospace part of their history dates back 60 years.  Debra did a good job in summarizing their aerospace history, including moving forward with NewSpace, non profits, cubesats and more.  Listeners asked our guest many email questions including her view of the trends in the space industry, especially among the entrepreneurial segment.  Other topics discussed included disruptive markets and technology, the launch industry, SpaceX, ULA & others, plus the need for viable, productive space  markets.  One market she talked about that was in demand was the market for space data.  Debra had much to say on this subject so don’t miss it.  Debra was asked about human spaceflight which she classified as exploration, discovery, and human nature.  Listener Jack asked Debra about space projects based on the “coolness factor” rather than commercial or national security value.  This proved a very interesting conversation so again, I urge you not to miss it.  Another listener asked about trends toward public only projects, public/private projects, and international cooperative space projects.  Near the end of the show, we had a few listener questions about kids studying engineering but preferring something like an Apple employment to NASA or the space industry because space projects take so long and are often cancelled.   Debra had much to say about this subject plus the potential of space to impact so many other fields.  This prompted an email from a listener who drives part time for Uber.  She pointed out how it was disruptive and based on space technology.  This too was a most interesting discussion that I am sure you will appreciate.  In conclusion, Debra paid her respects to the late George Mueller who recently passed away.   George was a great influence on her life , her career, and the space industry as far back as Apollo.  You can read about Mr. Mueller at http://spacenews.com/george-mueller-apollo-manager-and-kistler-founder-dies.

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!”

We welcomed Charlie Precourt back to the show to discuss SLS-Orion progress and milestones, human spaceflight, technology advancement, & much more. During our one segment 63 minute discussion, I first asked out guest about the Orbital ATK merger and business under the combined companies. We soon shifted to the SLS-Orion discussion which included information on the 5 segment solid rocket booster (SRB), tonnage to escape which our guest explained, possible missions, and opportunities that will become available as a result of having this heavy lift rocket available for missions that need the lift & high energy capacity of SLS. We talked about shorter travel times, larger payload mass & volume, plus higher energy transfer orbits using SLS as compared to an EELV. Charlies was asked about SRB safety for human spaceflight. Don’t miss his comments on this issue. He talked at length about the benefits of marrying the SRB for lift out of a gravity well to liquids for propulsion once in space. Our guest provided statistics on SRB launches and uses to support what he was telling us. Charlie also talked about his Space Shuttle flight experience and the Shuttle’s SME, especially when there was an SME problem on one of his shuttle flights. We talked about going BLEO and he introduced us to the concept of One Space. As a result of listener questions, our guest talked about SLS costs, its design for multiple destinations and missions, and the launch “sweet spot” that it would fill. BJohn asked if there were uses for an SRB or solid rocket motor in space. Charlie said for liftoff from a gravity well, yes, but otherwise the SPI for a solid was likely too low for in-space propulsion. I asked our guest about Orbital ATK meeting the SLS -Orion milestones and upcoming flight testing. Jeff from Tucson called in about the use of modern technology including light weight epoxy material for SRBs & other spaceflight hardware. Near the end of the program, I asked Charlie about the justification for HSF to see what he had to say about it. Don’t miss his reply. We then talked about technology challenges in going to Mars, choices that were made to do the shuttle and ISS over deep space missions, and destinations that were still Earth dependent as compared to those being Earth independent such as Mars. Jack emailed in a question based on a show earlier in the week where the guest said that for putting SPS infrastructure in space, SLS was too sophisticated. What was needed was big rockets that had a 2% failure rate as that rocket would be lots cheaper than an SLS. Charlie did not specifically comment on SPS infrastructure but did take issue with the notion that it would be fine to have a rocket with a high failure rate to make it cheaper than something like SLS. Listen to how he explained this. Tell us what you think on TSS blog. As the show was about to end, a listener ask Charlie, based on his F15, Air Force, and test pilot experience, what he thought of the new F35 Joint Strike Fighter and the shortcomings of the new fighter that are reported in the press. Charlie had interesting comments about this so don’t miss them.
