We welcomed back Dr. Madhu Thangavelu to discuss the Planetary Defense Team and their work at the ISU Summer Session which was held this year at Ohio University. About 20 minutes into the show, he was joined by one of the student participants in the session, Tihomir Dimitrov (Tisho). Madhu explained that he gave the team an impossible scenario to solve. The scenario was that a comet was heading toward Earth and would impact us in two yeas. The students had to come up with a mitigation strategy. The first segment of our program talks about the considerations, the plans, & the mitigation means which included directed energy and modified nuclear weapons. Listeners and I pushed both Dr. Thangalevu and Tisho on these two strategies, plus I challenged them on their goal of changing the world by engaging in planetary defense of the Earth, the Moon, and even Mars. I kept asking them why they don’t improve humanity in Africa and the Middle East because as host, I can play the part of the devil’s advocate to challenge their reasoning and thinking. In the end, it seemed that the solution to the problem was based on how much work was done in the time leading up to the discovery of the incoming comet. Our guests also talked about evacuation strategies and making touch decisions for the good of society and the planet but maybe not so good for the city, town, region or people that get hit by the comet. Its an interesting discussion and I am sure all of us would have enjoyed being in this summer session class. You can read the Executive Summary Report for this class at https://isulibrary.isunet.edu/opac/doc_num.php?explnum_id=719. The Final Report can be found at https://isulibrary.isunet.edu/opac/doc_num.php?explnum_id=722.

In the second segment, Madhu talked about his upcoming design studio class with the theme this year of exploring the role of the Moon in our future space activity. He talked about the role of governments in making the Moon part of our future in space as compared to the role of private companies and entrepreneurs. At one point he said the key would be in how we change the way we look at space. When asked by a listener, Dr. Thangalevu clarified that he was talking about the role of the Moon in human space activity, not just robotic missions. Madhu also directed us to his earlier articles in Mars Daily on this subject which you can read here: (1): www.marsdaily.com/reports/The_Moon_or_Mars_Flawed_Debate_False_Choice___Part_One_999.html; (2): www.marsdaily.com/reports/Flawed_Debates_begets_false_choices_beyond_LEO___Part_Two_999.html.

We welcomed Russell Cox to the program for our 92 minute discussion of the Lunar Initiatives workshops. Follow us at www.lunarinitiatives.com. Russell began the discussion by providing us with the background that led him to create the Lunar Initiatives workshop series. The start goes back to 2009 with the lunar missions that showed there was water ice at the poles. He said this changed the Moon and science for all time and opened up an entirely new realm of lunar possibilities and opportunities. He spent some time discussing the key lunar missions & their significance. Next, we turned our attention to the Lunar Workshops, Lunar Art, and the Lunar Challenges. All are described on his website so check them out. Regarding the workshops, he has a LunarCubes workshop, the Lunar Surface Applications workshop, the Lunar Scientific Opportunities in Cislunar Space (SOCS) workshop, and the Lunar Conference. Read about all of these events on his website but for our discussion, we mostly talked about LunarCubes and cubesats, Cislunar space, and near the end of the show, LunarArt. In addition to discussing The Lunar Initiatives events, Russell talked about returning to the Moon, lunar hackathons, prizes and contests, entrepreneurial efforts to go to the Moon, the Google Lunar XPRIZE, cubesats, the Do It Yourself (DIY) emerging markets, and more. Listeners asked him questions about lunar exploration, the technology readiness level of the entrepreneurs wanting to develop a business for going to the Moon, lunar settlement, lunar habitats, and using the Moon as a stepping stone for other solar system destinations. Don’t miss his response to these questions.

 

In the second segment, Russell spent more time on human lunar exploration and settlement and the need to push the technology today to do what we can today rather than waiting to be able to do more in future years. He said the road to the Moon is open! Russell described several existing opportunities including one by Space Systems Loral that you will find interesting. A listener asked him if we needed to focus on developing cislunar transportation, then our conversation switched to Lunar Art and their programs and contests in this area. He said poetry and short stories were included in this category and the contest. Late in the segment, Tim called in to raise questions about settlement given the possibility of gamma ray bursts plus comments from Dr. John Lewis regarding the Moon. Before the show ended, our guest addressed a few more listener emails, then spoke more about the LunarCubes program and website, www.lunarcubes.com.

We welcomed back Jeremy Straub with several of the student participants in this summer’s UND undergraduate research program for small spacecraft satellites. Jeremy was joined by Delia, Davila, Wentong Zhang, Samuel Jackson, Alexander Layton, Emily Jenkins, and Matthew Russell. During the first segment of our 82 minute program, Jeremy introduced us to students Samuel Jackson, Matthew Russell, Wanting Zhang & Delia Davila. Each student spent a few minutes going over their research project and interests. I’ve listed each student & their project in the bio section of this archive program but we did focus on issues dealing with cubesats and higher orbits with the need to deorbit them without causing debris. Neural networks were discussed along with adversarial examples and training problems using a grass and a cow as an example. Don’t miss this discussion. Samuel talked about cryptographic algorithms and picture encryption, then Matthew talked about the adaptive attitude control systems for a small satellite or cubesat. He said he was focusing on intrusion detection security for existing satellite security solutions. Jeremy added in details for each of the student research projects and tied the focus to smallsats, especially since all were attending this year’s SmallSat Conference in Logan, Utah.

 

In the second segment, Alex Layton led off with his project to find new ways to measure distances with cameras using image processing techniques. He addressed X-Y coordinate issues and more. Emily focused her research on astrodynamics for maintaining orbits and deorbiting small satellites and cubesats from much higher altitudes such as 600 miles above Earth. She had much to say about cubesat orbits today and how they were evolving to higher orbits in a very short period of time. Throughout both segments, Jeremy and the students spoke about various NASA programs and funding opportunities, getting a launch and being placed on a ride share launch manifest. We also had quite the discussion on cybersecurity issues, at times comparing a cyber attack to a physical attack on a satellite. Don’t miss what Jeremy had to say on this subject. As our program was nearing the end, we talked about the SmallSat Conference this year, networking opportunities for the students and their future plans.

We welcomed Brent Sherwood back to the show to discuss the rational, potential, and economics for the use of space solar power (SSP). During the first segment of our 1 hour 27 minute discussion, Brent first introduced us to Dr. David MacKay from Cambridge University who in 2009 was appointed Chief Scientific Advisor to the Department of Energy and Climate Change. Brent talked about Dr. MacKay’s book during our discussion, “Sustainable Energy-Without The Hot Air” which is available for free on the internet. You should follow along in the book with Brent’s discussion, especially in the first segment, as our guest referred to pages and visuals frequently. Check it out at http://withouthotair.com. Most of the first segment was spent using information from Professor MacKay’s book to explain the current energy and climate situation on Earth and to justifying moving away from petroleum, eventually to SSP. Brent talked about CO2, energy disruption, the transition to something other than fossil fuels, and how to develop SSP. Dr. MacKay used modeling for the UK which Brent referenced, especially from page 215 with the UK map. Brent then talked economics, again referring to the work by Dr. MacKay suggesting an SSP system costing $1.4 trillion! Spread out over a number of years, that price was not much different from what is spent on several government departments and policies, including NASA at this time. Brent listed several examples of this so don’t miss this discussion. Brent then suggested the least path of disruption would focus on the key which would have to be electricity. This took us to our next topic which addressed how to generate the amount of electricity needed, including his identifying several newer technologies that could lower some industry costs. He talked about some of the main challenges including transportation, storage, transmission, & operations. Later in the segment, Brent delved into the cost per kWh for electricity. Marshal called to talk about key new technologies including advancements in related and applicable photo voltaics and more.

 

In the much shorter second segment, Brent talked about macro engineering projects and huge platforms in GEO space. He said that such SSP GEO platforms would be around 7,000 sq. km. or three times the size of the paved U.S. national highway surface. Brent then addressed why none of this ever happens and he pointed to this not being a purpose of NASA as an example. To counter this, he advocated for a serious demo project, even suggesting the use of the ISS for the demo. Our guest talked about the challenge in attracting private capital to this because it is so futuristic right now. However, private capital has flowed to the futuristic industry of asteroid mining. We both asked why to one and not to the other? The last email question of the day was from Carol who pointed out that government policy to regulate coal and CO2 over 30 years is off point. Instead, government policy should produce a serious demo project that confirms the technology and the potential market, then let the markets and industry self-regulate and invest for the future.

 

Please post your comments/questions on TSS blog above. Brent can be reached through me if you want to contact him.

We welcomed Dr. Julie Robinson, ISS Chief Scientist, to the program. During our 71 minute discussion, Dr. Robinson provided us with an overview of science on the ISS, specifically identifying two goals: 1: Research for BLEO; 2: Developing LEO for long term space use and for benefiting life here on Earth. We discussed the logistics of science on the ISS, the ISS international partnership and how ISS resources are allocated to the partners for science as well as other projects. Our guest further broke this down between Russian and the U.S. and then said that for the U.S. segment, the U.S. has about a 76% usage allocation of ISS resources. We talked about the science done on the ISS, the mix with government and commercial projects, then we started talking about the 1 year study with the Russian cosmonaut and American astronaut while at the same time doing the Twin Study with astronaut Scott Kelly on the ISS with his brother Mark Kelly here on the ground. Dr. Robinson spent much of the balance of our interview time going into the specifics of these concurrent studies, the investigation categories for each study, and more. Our guest fielded questions about the length of time for the study being fixed at one year rather than being longer and objective oriented. As you will hear, ISS logistics, using the Soyuz as a lifeboat, and the overall ISS operations and other experiments going on all contribute to why a one year study was settled on rather than a long duration study or one based on achieving certain accomplishments or objectives. Dr. Robinson talked about the possibility of future studies given that they anticipate issues and information from this first study suggesting more refined studies to be undertaken in the future. Listeners emailed our guest several questions including asking her about the assumed low science productivity on the ISS, a statement Dr. Robinson refuted with evidence. BJohn also asked about low gravity issues. Later, in a follow up question, BJohn asked about a Phobos mission and doing human spaceflight mission simulations on the station. Don’t miss Dr. Robinson’s response to these questions. Dr. Bill Rowe called to talk to her about CO2 buildup, oxidative stress, EVAs, and possible magnesium deficiencies in astronauts while in space. We talked radiation issues, the OSHA rules for maxing out on radiation, and finding astronauts for the long mission that would not be disqualified due to the OSHA radiation rules. Vision problems, fluid shifts and other complications were discussed throughout our interview with Dr. Robinson. A listener commented that both participants in the 1 year study were men and wanted to know about gender differences which Dr. Robinson addressed. Another listener wanted to know about shared access of the information and if it would be made available to the commercial industry, the space tourism industry, even Mars One as an example. Later in the segment, Dr. Robinson went into much more detail regarding the investigation categories for both the 1 year and the Twin Study. When talking about fluid shifts, she was asked about differences in the Russian approach as compared to the American approach. One example that she provided us was the Russian use of their Chibis suit which sucks fluid back down to the legs. In making additional points in reference to space settlement questions, Dr. Robinson talked about comparisons with space to early oceanic exploration and said that people are not living at sea for their entire life even today. Don’t miss this discussion. Based on other questions, the human gravity RX was discussed along with the use and challenges regarding centrifuges in space, alternative propulsion to get to a destination much quicker, and the fact that even a low gravity body is better for people than no gravity. Again, don’t miss the discussion. We talked more about behavioral studies, Dr. Doug asked a series of three questions that took us through to the end of our program with other listeners asking questions in-between Doug’s. For example, cognitive issues came up as did timelines and influences to making rapid research progress including money and financing. As we were about to end, I did ask about genetic screening, experimentation, and modification. Don’t miss what our guest had to say about this and why. As we were ending, I inquired about research plans once the ISS was deorbited. Again, don’t miss the options that were discussed with us. Dr. Robinson left us with thoughtful concluding comments you will want to hear, plus she provided us with the social media contact information to follow ISS research on a regular basis.

Please post your comments/questions for this show on TSS blog above. You can reach Dr. Robinson at NASA or through me.

We welcomed Michael Mackowski to The Space Show to discuss his book “Adventures in Space Advocacy,” space advocacy in history through to the future, spacecraft model building and much more. During the first segment of our 90 minute program, Michael talked about growing up as a “child of Apollo” and being inspired by our early space program. He went on to get an EE degree and to work in the industry. He said it was an exacting time, especially when the Galileo Jupiter mission finally happened. He talked about the start of organizations such as L5, The Planetary Society, AIAA, and his own early ventures into space advocacy which are detailed in his book, available at Amazon at www.amazon.com/Adventures-Space-Advocacy-Personal-Activism/dp/1511564911/ref=tmm_pap_swatch_0?_encoding=UTF8&qid=1438189701&sr=8-1. He talked about moving, heading to Phoenix and engaging in space advocacy once again after a brief pause when he was in Washington, DC. This led us to a discussion about individual advocacy efforts as compared to group or organizational efforts. Michael was asked how he has sold human spaceflight to a general audience, his most receptive audience, and lobbying congress. Our guest spent some time discussing the challenges in advocating human spaceflight to the general public so don’t miss this discussion. Space tourism came up as a probable kick starter once the industry starts commercial operations. Michael thought that space tourism could provide a crucial boost for industry support even outside the space community.

 

In the second segment, we talked about Michael’s interest in spaceflight models. If you visit his website, www.space-city-mike.net, you can click on scale models on the right side menu bar (http://space-city-mike.net/modeling). Michael described the industry, licensing challenges, specialty model builders and more. He also talked about using models in the form of make and take kits when talking to young students about space. Model building through 3D printing was discussed, then I switched the topic to inquire about his success in outreach with adults and children. He said 5-7th grade was the best group to talk with as high school was probably too late. As for speaking to adult groups, he said it was usually about entertainment but that it seldom produced advocacy action on the part of the adults hearing the talk. I seconded that experience given my talks with adults on space this and that. Near the end, we talked trends, the increasing influence of social media, passion, and connecting pace to our future.

We welcomed Dr. Robert Pappalardo to the show to discuss Europa and the upcoming Europa Mission by JPL which is now in the development phase. During the first segment of our 1 hour 27 minute program, Dr. Pappalardo talked about the origins of the NASA JPL Europa mission now in the development phase. He briefly described the experiments & instruments planned for the mission, then answered questions about the mission such as will the mission search for life. In response to this question, he said it would search for simple life through an indirect means which he described more fully in the second segment of the show. Our guest talked about having learned lots from the earlier Galileo spacecraft, especially about the Europa magnetic field and the likelihood of the oceans consisting of saltwater. Dr. Pappalardo also talked about the structure of Europa with the icy surface, oceans under the ice ad then a rocky base under the oceans. Dr. Pappalardo brought up the tidal heating of Europa and spoke to that quite a bit during the show. He talked about chemical energy and nutrients which may support simple life in the Europa oceans. Listener Joe asked how Europa could be in a habitable zone, even for simple life, given its cold temperatures. Our guest said Europa was expanding the definition of habitable zone & that the tidal heating was crucial to the possibility of finding simple life molecules. Don’t miss his complete response to this question. We talked mission timeline which was from about 2022 to the mid-2020s. We also learned that the Europa launch window was every 13 months. Our guest was asked about transit time to Europa. He said it depended on the rocket. With SLS it would be less than 3 years. Another rocket would take at least 3.5 years or longer. We also discussed bandwidth issues for getting data, images, and video back to Earth. I asked about the possibility of using cubesats as part of the Europa mission, then Bob talked about the radiation challenge which he said was significant because Jupiter acts as a giant particle accelerator. Don’t miss this discussion, especially the part abbot how much ice would be needed for effective shielding. Also, the Europa satellite will come as close as 25KM to the surface of Europa.

In the second segment, Bob went into detail about the scientific instruments that will comprise the Europa mission. He took us through each one in detail so don’t miss it. The radar pushes the technology envelope. So does the mass spectrometer. Harry wanted to know if a plutonium RTG would be used for power and if they were anticipating Cassini like protests. Bob said that they would be using solar power. Again, don’t miss the discussion. Cindy asked Bob about the length of the Europa day and year, another listener asked about Europa volcanoes and we learned that Europa has icy volcanoes. Amber wanted to know if the ice on Europa was the same as ice here on Earth. A UK listener wanted to know why Europa was not sucked into Jupiter by the planet’s huge gravity field. Don’t miss Bob’s explanation of this. Toward the end of the segment, he talked about the significance and importance of the search for simple life molecules/organics. Final questions concerned specific Europa classes at the college level & more on the European JUICE Mission and its plans for Europa. We agreed to stay in touch with one another regarding Europa and the upcoming mission so Dr. Pappalardo will be returning to The Space Show.

Please post your comments/questions on TSS blog above. You can reach Dr. Pappalardo through me or JPL.

We welcomed Rex Ridenoure back to the show to discuss Ecliptic Enterprise, LightSail, the NewSpace Conference & more. During the first segment of our 1 hour 33 minute discussion. I started our discussion by asking Rex how Ecliptic got the LightSail contract from The Planetary Society. Rex relayed the story to us of their involvement with LightSail & I am sure you will find it interesting. This discussion led Rex to update us on Ecliptic activities with their size reduction program for their avionics and their work on cubesat projects. Rex talked about their customer and project base and why they don’t have foreign launcher contracts or relationships. ITAR!! He talked about their having been denied ITAR clearance in the past so they don’t even bother obtaining it anymore. Rex talked about some of their camera space projects including LCross, transmitting data back via the DSN and the limitations because their cameras could work all the way to Pluto and beyond but the data transmission rate and capacity to do that for video is not available. We then returned to the LightSail project which Rex described in some detail during the balance of our segment. Rex also has suggested we read the blog articles on LightSail via Jason Davis on The Planetary Society website. www.planetary.org/about/staff/jason-davis.html and look for his posts on LightSail. By the way, it is an excellent blog and I recommend you add it to your regular reading list.

 

In the second segment, Rex provided us with an overview of the SFF NewSpace Conference and I totally agreed with what he said having also attended it. In my opinion, it was the very best of all the SFF-NewSpace conferences I’ve attended since the late 90’s. As part of his summary of the conference, I asked his opinion on the Dr. Linda billings Scientific American article that attacked SFF, NewSpace, space settlement, etc. Here is the article in case you missed it: www.scientificamerican.com/article/the-inexcusable-jingoism-of-american-spaceflight-rhetoric. Let us know on TSS blog what you think of Dr. Billing’s article and what Rex had to say about it. Please be respectful and civil, no name calling, even if you strongly disagree with either Dr. Billings or Rex. Since our show ended, Shubber Ali, the original Space Cynic, posted a reply to Dr. Billings on the Space Cynics website. Check it out as I will add all of this to the Open Lines discussion for Sunday, August 2: https://spacecynic.wordpress.com/2015/07/27/the-inexcusability-of-poor-reading-comprehension. As the show neared the conclusion, Rex summarized key points & highlights of discussion.

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.

What Happens to your Brain on the Way to Mars

Guest: Dr. Charles Limoli. Topics: We discussed space radiation in the context of his paper, “What Happens To Your Brain On The Way To Mars?” Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, https://thespaceshow.wordpress.com.

This will help me bring better programming to the audience. We welcomed Dr. Charles Limoli to the program for this 90 minute discussion on space radiation and astronauts, especially flying in deep space, going to Mars or back to the Moon, evening residing on the Moon or Mars. You can read his paper which has been uploaded to The Space Show blog for this program. During the first segment, Dr. Limoli outlined the basics of his research. Before going deeper into the topic, I asked him several questions about the use of rodents and mice for the experiments, the possible use of other animals, the constraints and limitations of radiation simulation experiments, plus how these radiation experiments and doses differ from humans getting radiation treatment for cancer or other medical problems. We had quite the discussion on rodent brains compared to human brains, animal experiments in general, plus the protocols used in his experiments which were all carried out at Brookhaven. By the way, Dr. Limoli is a space advocate, he has received NASA funding for years, and he and his team have a great interest in radiation issues for human spaceflight. Dr. Limoli then took time to tell us how the experiments were conducted. Some of the discussion is technical so I suggest you read his paper which has been placed on TSS blog. Dr. Limoli went into significant detail to tell us how they conducted the experiments, applied the low dose radiation to the subjects, and how they evaluated the results. Don’t miss his description and analysis of the experiments. He said the changes were subtle measured 6-8 weeks out but he also said future papers may show that the cognitive changes continued to happen over a much longer period of time. In response to one of my questions, he said there was no sign of recovery. The primary changes that were observed and reported in the paper had to do with cognitive impairment which we discussed in detail throughout this program. I asked our guest about age, gender, race, and cultural differences. I also asked if NASA was now doing or might do in the future some genetic screening to find those best suited for a high radiation environment. Space settlement risks were talked about as was childbirth and pregnancy. Dr. Doug from S. California called to talk about GCR shielding. He wanted to inquire about using the stuff on the mission, food, water, supplies, etc. for shielding. He suggested the strategic placement of the stuff to maximize shielding. Dr. Limoli did say this was all factored in but that GCRs are non-directional so they come in from everywhere so such “stuff” shielding would only be partially helpful in protecting against radiation. For now, it would have to remain an unanswered question pending getting more research data. In this discussion, Dr. Limoli did explain the components of GCR and what they do to the body and the brain’s cognitive ability.

In the second segment, we took listener questions including several from our friend Dr. Logan. One such question wanted to focus on how deep you would need to go into the Martian surface to equal the protection of Earth’s radiation shielding. Our guest was not sure of the actual calculation but estimated 4-5 meters. Tim in Boston sent in a note quoting what Dr. Zubrin said about Dr. Limoli’s research project per his critique of the paper published in The Space Review May 11, 2015. Dr. Limoli said that what Dr. Zubrin was saying was wrong regarding the details of the experiment. It was a very interesting discussion so don’t miss it. Rhonda wanted to know what Dr. Limoli would say to Elon Musk were he charged with consulting for Elon for his Mars plan and desired mission. Don’t miss what he said he would tell Elon. Later in the segment, I asked our guest to connect the dots with radiation issues and the other human factors medical conditions. This too proved to be an interesting discussion so don’t miss this one either. Charles was asked to talk in more detail about the observed cognitive changes and the actual tests used to reach their conclusions. In his closing remarks, he stressed how important continued research was and strongly urged listeners to support science research, write our congressmen and women, lobby for and advocate more research as it is the research that will give us more information to mitigate and resolve our spaceflight challenges.
