Please note that I had some difficulty adding in the second segment sponsor messages at the end of the program so I apologize in advance for the editing issues. We welcomed Dr. Mark Brodwin to the program for a comprehensive discussion on galaxies, galaxy clusters, stars, and gravitational waves per the recent LIGO announcement. During the first segment of our 1 hour 56 minute program, Dr. Brodwin started out by providing us with a working definition for a galaxy, galaxy clusters, and galaxy groups. We talked about Andromeda, spiral galaxies, elliptical galaxy, the Milky Way, and the characteristics of galaxy stars and the light to mass ratio to determine the stellar mass. Our guest said there were lots of galaxies but galaxy clusters (his area of interest) were harder to find and much rarer. Dr. Brodwin then talked about how galaxy clusters are found, largely with x-ray telescopes and infrared telescopes such as Spitzer. Listeners sent in many email questions. James wanted to know about the possibility of seeing galaxies closer to real time or extrapolating what the galaxy might be like today given we are seeing them from 7-8 billion years ago. Ben wanted to know if telescopes would continue to improve to enable us to see even further back in time. Dr. Brodwin had much to say about telescopes and their capabilities now and under development. For a change in pace, BJohn asked about galaxy rotational information, citing the Backwards Galaxy. Tim in Montreal asked if a spiral galaxy might be better suited for life than another type of galaxy. While there was no information to support what Tim was asking, our guest did say that spiral galaxies seemed to have higher particles of dust in them and the dust helps make rocky planets so possibly a spiral galaxy might be more likely to have life on some of its planets but this was pure speculation though an interesting question. We discussed the cluster galaxy 1426 as we did with Dr. Brodwin on the recent Hotel Mars Program from Jan. 13, 2016. This show is archived and since it is short, I suggest you listen to it for more information on 1426 (www.thespaceshow.com/show/13-jan-2016/broadcast-2623). Additional discussion in the first segment talked about red shift, the value of studying galaxies from the public's perspective & the definition of a scientific theory. Here, our guest explained what theory means in science compared to the use of theory in the non-science world. This came up as a result of listener question pertaining to The Big Bang Theory.
Tom from Seattle called in about a picture and article on Wikipedia about our place in the universe as it caused him to have several questions for our guest. You can visit the Wikipedia page at https://upload.wikimedia.org/wikipedia/commons/b/b6/Earth%27s_Location_in_the_Universe_%28JPEG%29.jpg and https://en.wikipedia.org/wiki/Local_Group (scroll to the bottom of the page).

Anatoly Zak, Debra Werner, Friday, 02-12-16 (23.15MB; download) -- Guests: Anatoly Zak, Debra Werner; Topics: Astronaut safety issues per their Aerospace America October 2015 article, "Maximizing Safety." Please direct all comments and questions regarding specific Space Show programs & guest(s) to the Space Show blog which is part of archived program on our website, www.thespaceshow.com. Comments and questions should be relevant to the specific Space Show program.

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed Anatoly Zak back to the show and for the first time we welcomed Debra Werner to this 94 minute discussion on astronaut safety based on their Oct. 2015 article Aerospace America, "Maximizing Safety." You can read and download the article at www.aerospaceamerica.org/Documents/Aerospace%20America%20PDFs%202015/October2015/AA_Oct2015_MaximizingSafety_Feature1.pdf. We started the first and only segment off by asking Anatoly to provide us with the background for their story and research. As you will hear, our two guests wanted to more fully understand the odds of a fatal astronaut accident or illness, plus they wanted to know what both NASA and the industry were doing to minimize these risks and bring them within acceptable risk tolerance levels. Part of their research focused on the 1968 congressionally mandated Aerospace Safety Advisory Panel (ASAP). Our guests referred to the ASAP crew loss ratios and safety recommendations throughout their Space Show discussion. Before delving into the details of astronaut safety, I asked if their research included the suborbital industry or if it was only focused on orbital. Our guests said that suborbital needed serious attention to safety citing recent accidents and the always present launch risk. That said, most of our discussion was about orbital and BLEO human spaceflight. Our guests also pointed out the difficulty in comparing safety with the new spaceflight vehicles with that of the now retired Space Shuttle. Given such wide ranging differences in the vehicles, the missions, and even potential destinations, it was like comparing apples and oranges in terms of crew safety issues. Much of our focus was on the ASAP and SLS/Orion. They talked about the need for more testing but this and other safety implementation recommendations were challenged by insufficient budgets. Because of this, I asked our guest if they met with or discussed this subject with Congress and staff but unfortunately, they did not do so. An issue that came up many times was the proposed SLS flight rate. Most believe the flight rate is too low to maintain safety but our guests described the NASA approach to the low flight rate issue. Let us know what you think of the NASA way with your blog comments. I also compared this approach to needing specialized medical surgery. Would you want your surgeon to do only one or two surgeries a year and the rest of the time do simulations while waiting for the next real patient? That said, our guests were quick to point out the low flight rate for the Chinese human spaceflight program which the Chinese seem to handle without incident. This could serve as a model for the NASA approach regarding this issue. Listener Joe sent in an email asking about Russian Soyuz safety since NASA has no say so with the Russians yet they flight NASA astronauts on the Soyuz all the time.

John Batchelor and I welcomed back Chris Carberry of Explore Mars, Inc. to tell us about their upcoming annual event, Humans to Mars Summit, which will be held in May of this year at GWU. Not only did Chris tell us about this year's Summit, but he also mentioned several of the speakers for the event. John asked him about rocket reusability and 3D printing for future Mars missions. Chris had much to say about these advances but he was extremely confident about the possible contribution to Mars flights via 3D printing. I asked if Explore Mars was focusing on the 2016 presidential campaign. Chris said they would be working to make sure all the candidates knew the facts about going to Mars to help assure their support for future human missions to Mars. John asked about the private sector doing humans to Mars flights, settlements and more, either alone or with NASA. Don't miss how Chris responded to this subject.

Dr. John Brandenburg, Tuesday, 2-9-16 (29.41MB; download) -- Guest: Dr. John Brandenburg; Topics: Potential climate change, shifting to nuclear power as a solution, fission-fusion hybrid power sources. Please direct all comments and questions regarding specific Space Show programs & guest(s) to the Space Show blog which is part of archived program on our website, www.thespaceshow.com. Comments and questions should be relevant to the specific Space Show program.

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed back Dr. John Brandenburg for Part 2 of his Space Show Trilogy for early 2016. The focus of tonight's discussion was moving to a nuclear powered energy source to ward off any consequences from the possibility of climate change/global warming and the continued use of fossil fuels. Dr. Brandenburg made it clear that it was extremely difficult to assess the facts and the probability of climate change happening, along with all the disastrous results attributed to it, given the mess with the source data, the politics, corruption, and money involved in the discussion. That said, he believes that the continued use of fossil fuels is a bad thing regardless of climate change and global warming, and it would be better to start the shift to the solution now rather than waiting for a total crisis to hit the country and the world. John's solution is nuclear power and most of our discussion explained why nuclear power and ways to accomplish it safely. He cited many symptoms pointing him to his realization that we need to start the transition to nuclear power. One of the symptoms he talked about was the O2 depletion in the atmosphere, a topic he referenced several times during both segments of our program. John referenced the French nuclear power system over and over again given about 87% of their power is derived from nuclear power. He talked about modern waste removal processes which involved burning the wastes using Tokamaks referencing a University of Texas - Austin study. In making the case for nuclear power, he talked about the characteristics and limitations of wind and solar energy, plus he addressed the need for energy in the developing world and for the U.S. to continue with economic growth and development which requires enormous amounts of ongoing energy.
In the second segment, we picked up on a question from Bill in Virginia at the end of the previous segment asking about carbon in the atmosphere from the nuclear weapons testing in the atmosphere in the early 60's. Bill wanted to know about carbon dispersion from the atmosphere. John spent some time addressing this question, said it was an important one but was not aware of research specifically addressing what Bill was asking. In the context of this question, we talked about C14, C12, and C13. John From Ft. Worth called to discuss the sustainability of societies. Our caller advocated the need to eventually phase out carbon and fossil fuels. He also brought up the Fukushima accident in Japan and wanted to address nuclear power safety. Dr. Brandenburg again made the cause for using fusion energy to burn up nuclear waste. In response to my question about our not having B/E fusion energy, he said It was not necessary to have B/E fusion to burn up the waste. Read the rest of this summary @ www.thespaceshow.com.

Dr. Erik Seedhouse, Monday, 2-8-16 (21.78MB; download) -- Guest: Dr. Erik Seedhouse; Topics: We discussed Erik's book, "SpaceX's Dragon: America's Next Generation Spacecraft" & humans to Mars. Please direct all comments and questions regarding specific Space Show programs & guest(s) to the Space Show blog which is part of archived program on our website, www.thespaceshow.com. Comments and questions should be relevant to the specific Space Show program.

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed back Dr. Erik Seedhouse to discuss his new book, "SpaceX's Dragon: America's Next Generation Spacecraft." During the first segment of our 1 hour 35 minute program, Dr. Seedhouse opened up by saying that SpaceX had one purpose only, for Elon to go to Mars and bring others there to settle on the Red Planet. During our discussion, Erik received numerous questions by email from Tony and Rome who used the website Disqus program posting on the comments section as his email questions for the guest. Their questions continued through the entire discussion. Also during this initial segment, other listeners had questions about the Dragon V2 flight schedule, other models of the Dragon including those planned for use in Mars missions, Orion, and the Boeing CST 100.
Jack sent in a question asking if the SpaceX-Musk Mars mission and settlement rhetoric was different from the rhetoric put forth by the Mars One group. Don't miss how our guest responded to this question. Erik then received questions about the SpaceX Draco rockets but as you will hear, Erik was clear in stating that Dragon V2 was not for Mars and the Mars version of the Dragon was still an unknown. Erik spent a good amount of time discussing the various Dragon configurations so don't miss this discussion. One point Erik made over and over again dealt with the rapid development time SpaceX has incurred for Dragon, especially when compared to the time it has taken the government to develop Orion. In addition, our guest talked about the high costs for developing Orion plus the fact that the CST 100 is for the ISS only, not for going to Mars. In the second segment, Dr. Seedhouse said a goal was needed and Mars was the goal. He was asked about SpaceX plans for Mars, human factors, artificial gravity, and such. Erik said that information was not known but we both talked about anxiously awaiting the SpaceX Mars plans when they are announced later this year at the IAC in Mexico. In this segment, Erik mentioned using a Dragon for a Mars Sample Return Mission. Dr. Dwayne Day called and wanted to know who would pay for the Mars Sample Return Mission. Erik mentioned that NASA might join in given what he has been reading and hearing in the space world but Dwayne pointed out there was no funding for a sample return mission and the Decadal Survey had not planned for the actual return of Mars samples, just the collection of them with Mars 2020. This resulted in an extensive discussion with our guest and caller over assumptions, what SpaceX may or may not be able to do including landing on Mars using EDL techniques. Retro-propulsion came up and was discussed. Dwayne pointed out that SpaceX did not have this talent so he would have to partner with those that had it or bring on employees with this talent.

Jim Funaro, Sunday, 2-7-16 (20.11MB; download) -- Guest: Jim Funaro; Topics: Contact Conference 2016, special speakers & programs, anthropology, on and offworld plausible contact. Please direct all comments and questions regarding specific Space Show programs & guest(s) to the Space Show blog which is part of archived program on our website, www.thespaceshow.com. Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed Jim Funaro back to the program to discuss the 2016 Contact Conference to be held at the Domain Hotel in Sunnyvale, CA from April 1-3, 2016. For full conference, hotel, and registration information plus a list of speakers and topics, visit www.contact-conference.com. For the fist part of our discussion, I asked Jim to provide us with the history of the Contact Conference which goes back 27 years when Jim founded the conference and organization. He also talked about the significance of anthropology and the focus of Contact which may not be what you think it is so listen carefully to Jim's introductory comments. For the balance of our discussion in both segments, Jim went over the conference for this year, guest speakers and topics, the Keynote address and the simulations provided for students on the last day of the conference, Sunday, April 3. He talked about conference structure as it is a one track event, the focus this year on Mars and why so with the special Mars speakers including Kim Stanley Robinson, Andy Weir, Chris McKay, and Larry Niven. Conference logistics were discussed with news of the upcoming change in conference and hotel prices set for March 1 so if you can attend, you certainly want to register and sign up by the low price deadline. In the second segment, Jim stressed the diversity of the conference in terms of topics, speakers and those attending, along with the interdisciplinary content. He was asked about focusing on ET but said Contact was more of a professional conference, modeled after an academic conference and it was not a fan club type of conference. He went over many of the other speakers and their topics, all of which served to illustrate the uniqueness of the Contact subject matter and talks. He also stressed the networking opportunities for everyone. In response to a listener question as to the conference being appropriate for a ten year old, Jim talked about their educational programs and willingness to talk with school kids, plus he mentioned the age appropriate simulations. Before the program ended, we talked about remembering Contact supporters and contributors no longer with us including Dr. Al Harrison and Dr. Marvin Minsky. Al was a true personal friend of mine and a gust on the program several times. He was one of my favorite guests and a person I had lots of fun with at conferences and even went up to Davis, CA to meet him for lunch a few times (about a 90 minute drive for me). Personally, I miss Al very much and I miss his being on the show and his books. Unfortunately, I never knew Marvin nor was he a guest on the show but still a great loss to us all. Before our discussion ended, we summarized the conference and registration logistics. Please post your comments/questions on the comments section for this archived program on TSS website. Jim can be contacted through me or the Contact website. Selected by: David Livingston [ stations ], Mon, 08 Feb 2016 16:27:05 UTC

Dr. Jens Hauslage, Friday, 2-5-16 (14.30MB; download) -- Guest: Dr. Jens Hauslage; Topics: The DLR C.R.O.P Project & new approaches to closed loop life support for space missions. Please direct all comments and questions regarding specific Space Show programs & guest(s) to the Space Show blog which is part of archived program on our website, www.thespaceshow.com. Comments and questions should be relevant to the specific Space Show program.

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed Dr. Jens Hauslage, DLR specialist in bio-regenerative life support systems for space, to discuss the DLR's C.R.O.P Project (Combined Regenerative Organic Food Production). You can find out more about this project and closed loop life support for space by visiting these DLR websites: www.dlr.de/irs/en/desktopdefault.aspx/tabid-9328/15375_read-39519 which focus on the C.R.O.P. Project in addition to www.dlr.de/me/en/desktopdefault.aspx/tabid-10394 which focuses on the DLR test mission EU CROPIS. The reviewed and published paper we referenced during our discussion, "Natural microbial populations in a water-based biowaste management system for space life support" can be found at www.ncbi.nlm.nih.gov/pubmed/26553636. During our one hour discussion, I first asked Dr. Hauslage how he got his interest in space, in particular in the subject of closed loop life support systems and bio-regenerative life support. His story is interesting in that the path to becoming a leading scientist in this field was not that different than the paths many of us and many of our younger listeners are following with regards to their space interests. To me, it confirms the enormous opportunity people have in the space and science fields, opportunities in my mind that should not be overlooked. He was interested in space at an early age, was inspired by the different space missions and programs, films, also by Biosphere 2 and more. Don't miss his personal story. Next, I asked Dr. Hauslage to describe the C.R.O.P. project to us which he did for our one hour discussion. He went into detail about life support issues, specifically closed loop life support issues, nutrients, fertilizer, recycling of human waste, the biofilters being used including lava rock, nitrification, soil bacteria and how it is impacted by different levels of gravity, say Earth, the Moon, Mars, and microgravity. He was asked about time lines for advancement to operational systems such as he was developing plus he was asked if more money was the answer. As you will hear, developing, researching, testing, and demonstrating takes times so while more money would be helpful for financing the projects and research, it would not necessarily speed up the development timeline. A few listeners, especially Harriet, emailed in that the entire idea of human waste recycling was disgusting so she asked if astronauts and researchers had to go through any special type of de-sensitizing training to either work in the field or use the products. Our guest had much to say about this subject for the future of human spaceflight but also for developing countries here on Earth. Please read the rest of this summary @ www.thespaceshow.com.

Other contract winners included SpaceX and Orbital ATK. Jeff went over the history of Dream Chaser, we talked about the capsule vs. the mini-shuttle design, as well as Dream Chaser being reusable with a proposed 60 day turnaround. John and I asked our guest to compare the Dream Chaser return cargo capacity to that of the SpaceX Dragon capsule. As the segment was ending, we asked Jeff about the Falcon Heavy schedule and delays being encountered with the Falcon 9 launch schedule.You can email Mr. Batchelor or Dr. Foust through me at drspace@thespaceshow.com.

For those listening to archives using live365.com and rating the programs, please email me as to why you assign a specific rating to the show. This will help me bring better programming to the audience. We welcomed Robert (Bob) Zimmerman back to the show to discuss a variety of space and space related topics. During the first segment of our 1 hour 58 minute program, Bob started out by discussing the presidential candidates and their positions on space and science per a recent Science journal article. Bob reported this on his website, www.behindtheblack.com. If you want to read about it and see the actual Science article, visit http://behindtheblack.com/behind-the-black/points-of-information/the-candidates-take-on-science. Bob's website reports on more than just space news and it’s a good one so I suggest you check it on a regular basis for interesting and timely articles. Bob's next topic was an exhaustive discussion about SpaceX recovering their fist stage back at the Cape, plus he described what he said would be the impact of reusability on other launch providers, governments, and the industry. Bob's assumption making was quite generous but assuming reusability does become commercially operational, the potential is there to change the industry and commercial space in ways that Bob suggests. It also has the potential to impact the foreign launchers, especially if the foreign launch providers stick with old business models that SpaceX and reusability may over time weaken or even destroy. Listen to what Bob said and see if you agree. Post your thoughts in the comments section for this show on our website. Marshall called to talk about the RD 180 engine issue, Senator McCain, the future of ULA. Bob had much to say on this topic so don't miss the discussion. Politics entered into it as the RD 180 is made in the Ukraine by a Russian company and Russia is currently invading the Ukraine, plus the US wants to sanction Russia for the Ukrainian invasion yet the Atlas 5 needs reliable engines for USAF & national security launches. I know, it sounds like a SNL skit, right? NASA budget issues came up, especially looking on into the future. I used the opportunity to talk about the risk for NASA and others in the discretionary part of our budget due to rising interest rates. The James Webb Telescope was also mentioned so Bob gave us a short progress report on it. Bob had much to say about Blue Origin and its success with its reusable program, including flying the same fist stage a second time. He said Blue was clearly in the lead in the suborbital industry, then he spoke his mind on Virgin Galactic and XCOR.
In the second segment, Tim from Huntsville called (the first of his many calls during this program) to ask Bob for his opinion on Dr. Brandenburg's nuclear explosion on Mars theory.

We welcomed back Dr. John Brandenburg who advanced his theory and discussion that at one time long ago in the history of Mars there were two giant nuclear air burst explosions that left Mars pretty much as we see it today. For more information, visit his website at http://lifeonmars.pub. He said these blasts were in the range of 1 billion megatons. During this segment, he put forth his theory and the evidence which he said supported his conclusion. Much of this evidence revolved around isotopic radiation and findings in the Martian atmosphere, areas of thorium on Mars, Trinitite, neutron radiation, Argon, Xenon 129 and more. Listeners asked him many questions about his data and his conclusions. You will hear it all in the first segment. Also in this initial segment, Dr. Brandenburg challenged other scientists to a Space Show debate about his theory. He explained the history and the nature of academic debate and the place it has had in science history. He even referenced debates with Alfred Einstein and Niels Bohr. He said Einstein lost the debate which resulted in the establishment of rules for quantum mechanics. You can read about the debates here: http://uh.edu/engines/epi2627.htm. John was wanting to make the point that through robust academic debate, science can evolved. Thus, he challenged other scientists to debate him about his nuclear bomb explosion theory on Mars rather than just attack him from the shadows and those often mysterious space-themed blogs. For the balance of the first segment, John answered listener questions via email and phone calls. At one point he compared the development of Mars with that of Earth at the suggested time of the explosions. He also talked about validation of his theory would mean there had been life on Mars at one time. In the second segment, Tim from Huntsville called to ask John about the Martian atmosphere based on the data received so far from the NASA Maven satellite orbiting Mars. This opened up a large discussion about the Martian atmosphere which he said was likely blown away in large part by the nuclear bombs. Other listeners asked Dr. Brandenburg why there were no nuclear explosions elsewhere in the solar systems. Venus was a topic that he addressed at some length in both segments. He was asked why Mars and not Earth. Again, our guest talked about different rates of evolution between Mars and Earth, suggesting Mars was far more advanced than Earth . He provided reasons for this as well. Later in this segment, Joy in Boston asked Dr. Brandenburg what type of evidence would be needed to completely confirm his theory. John talked about scientific theories never being 100% confirmed. Read the balance of the summary @ www.thespaceshow.com. Selected by: David Livingston [ stations ], Tue, 02 Feb 2016 14:21:05 UTC
