We welcomed Dr. Bruce Damer back to the show to discuss his 3D real time simulations, the human NEO mission study & design project, planetary protection, astronaut safety and much more. Here are the websites Bruce mentioned on air: www.damer.com, www.levityzone.com, and www.digitalspace.com. In addition, later in our discussion Bruce also talked about a Dave Brody YouTube video that was relevant to our discussion. You can find this video at www.youtube.com/watch?v=UAm9escDxu0. In the first segment of our 1 hour 31 minute discussion, Dr. Damer talked about the renewed interest in asteroid projects within NASA and by others, especially after the Russian event a few months ago. Dr. Damer had lots to say about a recent meeting he attended at AMES, budgets, and the renewed interest in the subject. Listeners started asking him questions early on, including questions about docking with an asteroid with little or no gravity, the use of aerogel to collect micrometeorite particles, plus the recently announced commercial asteroid missions being planned. Robots versus humans came up many times, Curt asked about the use of the ISS, prioritizing budgets, lunar basis, etc. Doug called in regarding the incremental approach Dr. Damer had mentioned or as referred to in our discussion, stepping stones.
In the second segment, we talked about the designs on www.digitalspace.com and the Brody YouTube video per the above URL. Also discussed was planetary protection with the use of the gravity tractor. We talked about needed lead times to interfere with a potentially dangerous NEO that might be headed for Earth, then more questions came in about a lunar base and what Bruce thought to be more important, the lunar base, Mars, or the NEO mission. Doug called in to discuss and challenge some of the mission planning ideas Bruce put forth, especially around trial and error, R&D, incremental development and long time lines. Near the end, we talked about human spaceflight safety & the ideas put forth by Rand Simberg & others that we needed to take more risks, not make safety the extreme priority. Bruce had many relevant & important comments on this subject. Final comments focused on 50-100 years in th future with asteroid & other capabilities but only if we keep moving forward today.

We welcomed Dave Ketchledge back to the program to discuss Mars precision human spaceflight lander choices. During the first segment of our 2 hour 13 minute discussion, we covered Dave’s basic thesis and analysis regarding landing large payloads on Mars and the need for very accurate and precise landings for the human spacecraft. While at times the first segment was technical and perhaps complicated, it provided the necessary groundwork and foundation for our discussion during the second half of the program. During the first part, Dave explained the need for a precision human landing on Mars, the difficulties in doing that, the pros and cons of the various shapes to use for the human spacecraft, and why the Pershing 2 missile nosecone offered the best shape and design. Dave cited his references for his analysis and conclusions.
In the second segment, we started with a listener question about the origin of the DC-X vehicle design as it was related to the analysis, conclusions, and explanations Dave provided earlier in the discussion. Dave continued his comparison and analysis of the three potential vehicle designs, then I asked a series of questions sent in by listener Curt from the recently held Humans to Mars conference regarding issues in landing a large payload on Mars. Dave also spoke about heavy lift and the need for an SLS type vehicle, speaking to the additional needs for using smaller launches. These needs include planning on replacement launches and payloads which must be figured into the costs as all the advance launches of supplies & materials to Mars will be mission critical launches. The crew should be the last launch to the planet. Listeners both emailed in questions for Dave and additional listener phone calls were received. Dave continued to reference the NASA Mars Design Study, work done by JPL, Dr. Robert Manning, and others. We talked about the Mars One program & how it might land its human crew on Mars. We also talked about HSF to Mars policy &the absence of political leadership for a human mission to Mars. Dave addressed media issues but largely stayed with the shape of the human spaceflight spaceship, the need for a precision landing, and what might work best.

We welcomed back Dr. Bill Rowe to the program to discuss his important discovery regarding four Moon Walking astronauts. In our first segment of this two hour discussion, Bill explained his latest research findings& what his conclusions mean for human spaceflight. To find out more about Dr. Rowe’s research, to read his papers, & to learn more about telomeres, oxidative stress, & astronaut cardiac issues, visit his website www.femsinspace.com. In this segment, Bill talked about damaging the lining of the endothelium, too much or too little adrenalin & magnesium, & the four Moon Walking astronaut abnormal stress tests. Our discussion then turned to the Inspiration Mars flyby mission which our guest said was not survivable. Bill went over his reasons for his conclusion regarding this proposed 501 day mission& talked about 1G being the law & what that means for our bodies to be in less than a 1G environment. Bill then talked about telomeres & possible damage for the round trip Mars mission, plus he talked about the lack of an effective space exercise protocol as well as problems with prescription medications in space, including the need to deliver medicines subcutaneously but there is no such subcutaneous drug delivery system. Several times during our discussion, Bill said we might not be ready for humans to Mars for a long time, he kept asking what the rush was to go so quickly. He commented on the Buzz Aldrin cycler plan which he thought was doable 22 plus years from now assuming our research advanced in the time leading up to such a mission. Bill talked about radiation, including the recent data NASA released from the RAD instrument on MSL in space & on the Martian surface. Eric sent in a clarification comment about the possible death of an Inspiration Mars crew member& he asked Bill about his exercise statements which he said did not seem to be in agreement with statements made by other aerospace medicine professionals. Dr. Dear emailed in a question from the UK about Bill’s thinking that there will be no survival chance re Inspiration Mars. He compared that to the record in space held by the Soviet Cosmonaut on Mir, citing that record as reason to think that the crew could survive the 501 day Mars trip which would only be about 64 fewer days in space than the Mars flyby mission.
In our second segment, we talked about possible lessons learned from the Inspiration Mars flight & Dr. Rowe talked more about the Buzz Aldrin Mars plan. Bill then moved to the issue of females being better suited for spaceflight than men. He had much to say on this subject plus he has several papers addressing the subject on his website. Hint: Iron toxicity is a big issue. Dust issues were discussed in this segment& Bill talked again about his submarine analogy on oxidative stress from his website (www.femsinspace.com/Oxidative_stress.htm). When asked for some recommendations, Bill talked about the need for centrifuge studies & suggested rat studies with an on orbit centrifuge.

We welcomed Dr. Rowe back to the program to discuss his latest findings regarding four Apollo astronauts, lunar dust, microgravity, and cardiac conditions. His work is presented on his website so do check it out, www.femsinspace.com. Dr. Rowe’s latest findings came from his research using the Freedom of Information Act to get medical data from NASA after the recent passing of Neil Armstrong. During our first segment, Bill explained what he found, what specific blood pressure and other information strongly suggests, and his comparison of the Armstrong data with that of several other Apollo astronauts per available data. He also brought our attention to the problem independent researchers have in getting Apollo information and medical stats from NASA. Bill used stress test blood pressure numbers and other medical information from the astronauts in question to illustrate his points and to back up his conclusions. Most of our first segment was devoted to Dr. Rowe putting forth the information and his conclusions. Bill took several email questions and listener calls, often wanting more information than he could provide because the reality is that there is an absence of additional information or relevant studies suggested. One listener was asked if the ISS astronauts evidenced similar cardiac problems. Dr. Rowe was unable to answer that question due to the absence of information.
In the second segment of this 2 hour 20 minute program, Dr. Rowe connected problems of lunar dust with urban pollution, suggesting microgravity studies that would benefit millions on Earth given how widespread the problem of urban pollution is on the planet. One of the studies he proposed would use 30 female rats subjects to different calcium/magnesium rations on the ISS for six months. Bill spent time in this segment explaining the importance of the calcium/magnesium ratio and what this means in space and for us back here on Earth, hence the rat study. Dr. Rowe also talked about the difficulty of having a quality exercise RX for microgravity. A listener asked about studies related to the Mt. St. Helens eruption several years ago re dust exposure. Near the end of our discussion, Bill talked about their being no hurry to go to Mars, suggested many of the near term human spaceflight missions such as one way trips to Mars won’t happen for a long time because the human issues will not be resolved in the near term. He also advocated the Moon first. We talked about artificial gravity and I mentioned what other human factor gusts have said on air in that artificial gravity may not be the same as 1g here on Earth and may prove to not be a solution. Listeners did not like hearing that as they kept saying there would be an engineering solution to the microgravity issues. Listener disagreements about artificial gravity not being the same as earth gravity continued long after the program ended.

Guests: Open Lines with Dr. David Livingston. Topics: A short film – Angelfish, human factors for space travel, artificial gravity, space communications, science fiction movies & long term science projects, risk taking. You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. This is about a 2.5 hour Open Lines discussion. We started by talking to Michael Tyburski, an independent film maker who made a short film, Angelfish, and used The Space Show clips in the background. Michael described his film, why he put The Space Show in it, and more. Visit www.michaeltyburski.com for more information. Next, Dr. Jurist talked with us about artificial gravity & the chart he created to show just how big the radius would have to be to spin at 1G & other levels including lunar as well as Martian gravity. This chart is on The Space Show blog so you can follow along with what Dr. Jurist talked about regarding artificial gravity and spin rates. Our last caller for the first hour long segment was Jay who discussed the Space Literacy Foundation (www.spaceliteracy.org). Jay talked about the need for better space communications with the public as a way to facilitate more support for space. He also responded to questions I asked him about myths dealing with our early space program and the general population. If you are interested in what Jay is doing, contact him through his website.
In our second longer segment, Ron called in to talk about the history of the wheels on the Lunar Rover and an ad campaign by Goodyear that incorrectly describes the history of the rover wheels. Ron talked about the use of piano wire, how the original wheels were made, who made them, and more. The paper about this important history that we mentioned on air can be read at www.hq.nasa.gov/alsj/lrv_historical_origins.pdf. We talked about the history of the lunar rovers, the cosmic radiation impact on them over time on the Moon, and their design which included harmonic drives and engineering to shield from lunar dust problems. He mentioned a good source of information, a journal edited by Eric Jones & Ken Glover, the Apollo Lunar Surface Journal. You can find this journal at www.hq.nasa.gov/alsj. Ron directed listeners to the document section for Apollo 15, 16, and 17. John from Atlanta followed Ron, had much to say about the recent success of the Dragon & Falcon 9, then he talked about human factors, one way Mars missions as being suicidal, the regulatory environment & the possibility of excessive or restrictive regulations. We also talked about the new sci-fi movie, Prometheus. The article I mentioned about the movie can be read at http://cavalorn.livejournal.com/584135.html. If you plan on seeing the movie, I suggest you see the movie first, then read the article which is titled Prometheus Unbound: What The Movie Was Actually About. It is written by Cavalorn. Tim was our final caller. He took issues with human factors medicine & Dr. Rowe. Also the risk of over regulation, especially if someone dies going to space. He expressed his thoughts on other things as well. While our discussion was civil, as you will hear, I did not agree with much of what he advocated. I urged him and other space enthusiasts to be more inclusive of other ideas for space exploration and development rather than just believing their way is the best or even the only way.
If you have comments/questions, post them on the blog. If you want to email those that called us, send your note to me & I will forward it for you.

Homer Hickam, Friday, 4-13-12
Guest: Homer Hickam. Topics: We discussed his new book “Crater” & how he developed the technologies & systems to make living on the Moon credible. You are invited to comment, ask questions, & discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, & any discussion must be relevant & applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed back Homer Hickam to the program to discuss his new book “Crater” & his new Kindle book, “Paco: The Cat Who Meowed in Space.” You can buy each book from Amazon using these special URLs & Amazon will make a contribution to The Space Show/OGLF: For “Crater,” use www.amazon.com/Crater-Helium-3-Novel-Homer-Hickam/dp/1595546642/ref=onegiantlea20. For “Paco,” use www.amazon.com/Paco-Meowed-Kindle-Single-ebook/dp/B007K1OC6K/ref=onegiantlea20. Homer explained that Crater (set 120 years in the future) was a teenage orphan working to mine HE3 which was sent back to Earth as Earth desperately needed it for fusion energy. While telling us about his book, we learned that Homer created solutions to many of the challenges to living on the Moon. For example, microgravity & radiation – listen to how he solved the problems. Muscle deterioration? He solved that one too. Transportation back & forth between Earth & the Moon? That one too. Spacesuits, the use of one atmosphere, all sorts of other challenges to our having a lunar settlement have a solution to make the Crater story credible. As you will hear, not only does Homer go into detail about the storyline, but he focused on the solutions & this makes the story both believable & credible. Issues such as lunar dust, children on the Moon, even pregnancy, well, there is a solution. Food & water too. We did go off the topic of his books to ask about space policy. As you will hear, Homer thinks the Moon will be developed by entrepreneurs for commercial value. He sees companies such as Space X changing the game for our space policy & does not see government space programs being what they once were though development of needed infrastructure is part of what government can & should do. The lunar transportation systems he talked about will be private commercial businesses. When asked how he came up with solutions to problems encountered when living on the Moon, he talked about a study he did in the 1990s which is on his website, www.homerhickam.com. Homer was asked why the Moon & not Mars. Don’t miss his response to this listener question. We also talked about the space programs for other countries such as China. Homer then told how he envisioned the world to be 120 years in the future. As you will hear, countries have broken up into smaller, more manageable nations, including the United States. The world is not as we know it today. Toward the end of the first segment, Homer was asked about the difference in times from when he grew up in W. Virginia to today given the listener said his son could not even fly an Estes rocket in their city. Part of his reply stressed the need to join rocket clubs today. Before the break, we talked about insitu resources, water, food, law, & justice on the Moon.
During our short second segment, Homer was asked about strip mining on the Moon & he had much to say about it. Don’t miss this discussion. He was also asked about other uses for the Moon besides HE3 including solar, radio telescopes, & manufacturing. As the show ended, he commented on the need to have better political leadership to lead us forward in space development. He also had more to say about slime mold which plays an important part in his book.
