We welcomes Bob Zimmerman back for a two hour wide ranging discussion on space news, company updates, sequestration, policy, and more.  Be sure to check out his blog, http://behindtheblack.com.   Bob started out talking about the e-book release of his book, “Genesis, The Story of Apollo 8.”  He then talked about the upcoming Falcon 9 launches, their importance and significance.  Bob mentioned ILS and the Proton rocket which is having its problems causing insurance rates to rise. He said the Russians will absorb all insurance cost increases to keep Proton at a price advantage point.  This opened the door to a discussion about SpaceX and price competiveness in the launch industry.  Bob switched gears to the suborbitals and said we should be seeing Virgin powered tests soon.  He also talked about Stratolaunch per a recent Parabolic Arc article.  Bob was talking reusability and the RLV so I asked him if he was aware of economic analysis and data that was not supportive of an RLV short of a substantial increase in launch demand. Bob had much to say about this with his opinion. The RLV economic issue continued to be discussed in both segments of our program. Tim called in about it as well.  We talked about Sen. Rubio and his budget amendment suggesting NASA divest itself of unused assets & use the saved money for commercial space.  Bob then brought up sequestration and the announcement that NASA will be shutting down all public outreach but they will keep their PR arm going for their projects and missions.  We also mentioned Sarah Brightman and both her ISS and Virgin space tourism efforts.  Near the close of this segment, Inspiration Mars was discussed and as you will hear, Bob is skeptical, citing human factors & other reasons for his opinion.  Larry asked about North Korean rockets and threats to the U.S. west coast.  Bob said he took them seriously though their rocket was not yet ready for prime time. Bob also threw in Iranian rockets and threats and said he was more concerned about advances by Iran than N. Korea at this time.

In segment two, we talked about both the science side of NASA and the HSF side.  I’m sure you will find the comparison and mission summaries of interest.  John called in from Atlanta to raise yet again the question of reusability.  He thought it would be enhanced with the use of orbiting fuel depots. Bob was skeptical.  Don’t miss this discussion.  I asked both Bob and John about Inspiration Mars, Jim emailed in a comment about Falcon 1 relative to comments being made by Bob, and we talked about the upcoming Orbital Sciences Antares launch.  We got into the subject of risk taking and Bob and I talked about mining risks as well as caving risks.  As Bob is an accomplished caver, he had much to say about both mining and caving.  Near the end, we got a call about various spaceports in different states and spaceport commercial success so far.  Bob concluded saying that we are in an unstable world which could absolutely adversely impact all aspects of space and commercial space development and progress.

Dr. Vadim Rygalov, Annie Wargetz, Sunday, 11-4-12

Guests:  Dr. Vadim Rygalov, Annie Wargetz.  Topics:  Dietary impact & related nutritional issues for extreme habitats & spaceflight. Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, https://thespaceshow.wordpress.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.

We welcomed back Dr. Vadim Rygalov and for the first time UND SpSt graduate student Annie Wargetz to discuss her exceptional research regarding dietary & nutritional requirements for deep space mission astronauts.  Using Earth models such as submarines, extreme habitats, historical explorations, the Antarctica habitats, plus the ISS, our two guests shined an important light on a seldom discussed set of issues regarding astronaut nutritional challenges for deep space missions.  In the first segment of this two hour discussion, Dr. Rygalov introduced the subject to us & then he introduced us to Ms. Wargetz to discuss her work, research, & findings.  Many topics & issues were covered in this segment ranging from a broad discussion about extreme historical exploration missions, Earth habitats, submarines, the ISS, & more.  We learned what is known about deep space nutrition & astronaut food, eating, & caloric issues.  Annie talked about what we have learned from the different terrestrial models referenced in our discussion, plus many other issues presenting challenges such as food preparation, the lack of anything fresh, the lack of color in food, & the use of processed & chemical foods as is the standard for today.  She also talked about plans to mitigate these challenges on deep space mission flights. Bringing fresh vegetables, seeds, even small animals on a mission are plausible & were addressed.  One caller asked for a definition of a closed life support system.  Both our guests went into detail about this, including partially closed systems, bioregenetive systems, physical/chemical systems, & hybrids.  Vadim brought us current with our existing technology & what is likely to be available in the near term.  This is a comprehensive discussion pertaining to deep space environmental systems.

We started the second segment with our guests answering a question from the firsts segment about married couples in space.  Don’t miss their response & what Vadim said was his choice for the first crew for a deep space mission & why.  Mars 500 & Biosphere 2 were mentioned in their response.  Two other issues that were discussed were transit times to Mars with the faster travel time mitigating some of the human factor challenges including nutritional issues.  Also, it was clearly stated that to take on board the right type of nutrition, fresh items, seeds, perhaps small animals like chickens, a heavy lift launcher such as SLS was needed as the nutritional/food items will consume payload on the mission.  Vadim said heavy lift was needed to carry out the mission in one launch given the need for substantive payload dedicated to food/nutrition & astronaut well being.  Gender differences were discussed which is why Vadim suggested an all male first crew.  Other questions were asked about artificial gravity, developing & using a nutritional pill for space missions, issues about why astronauts don’t eat much on the ISS & more.

Open Lines, Tuesday, 6-12-12

http://archived.thespaceshow.com/shows/1794-BWB-2012-06-12.mp3

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, https://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.
