We welcomed Dr. Erik Seedhouse back to the show for this 1 hour 28 minute discussion regarding suborbital space and Erik’s new book, “Suborbital: Industry at the Edge of Space.”  In the first segment, Erik started out by telling why he wrote the book and he gave us updates regarding the prominent suborbital space companies.  We talked about payload flights, science flights, academic flights and space tourism flights.  Dr. Seedhouse spoke to the need to lower the cost for the flights and the need to prepare for painful accidents.  Listeners asked him to describe the flight profile for SpaceShip2 and the training many of the passengers had taken at the NASTAR Center.  Erik then spoke about competing centers, the American Astronautic Institute in Florida and Waypoint 2 Space which is adjacent to NASA JSC.  Questions came up about Astronauts4Hire and & the need to self market to get a flight.  Erik talked about floating free during the microgravity part of the flight on Virgin, addressing the issue of getting back to your seat on time before reentry.   Near the end of the segment, a listener asked why it was taking so long for suborbital flight we it was done decades ago and the information is in the public domain.  Ham the Chimp got mentioned in this section.  As the segment was closing, the new topic of space motion sickness came up.

In the second segment, a listener wanted to know if it mattered to the passenger re medical issues if vertical launch was used or horizontal launch was used.  Erik said the g force was the biggest medical problem with suborbital space.  He also talked about long arm centrifuge training, then he went over the Anti-G Straining Maneuver to deal with g force issues.  Space suits came, space tourist physical conditioning was discussion topic as was space radiation which Erik said was not a problem for suborbital flights.

We welcomed back Drs. Jurist and Logan to this CLASSROOM program which addressed many issues of the 2 hours 1 minute broadcast.  We started out with Dr. Logan discussing fantasy or magical thinking going back to the influence of a 2001 Space Odyssey movie poster had on him.  From there, Jim went into a discussion about Constellation, then the Space Shuttle as examples of what he was talking about and as to how programs and faulty ideas grow and multiply.  He also talked about life science challenges.  A listener asked him about space politics, then Dr. Jurist offered additional examples with a focus on air launch.  Our guests then discussed thinking based on agendas and ideology.  One of the keys suggested for breaking out of this magical thinking mode involved surrounding yourself with really smart people.  Later, I offered my perspective on that given my own experiences early on in Space Show time and before.   Both Jim and John said a few times that one needs to know his or her limitations.  Our guests then talked due diligence with assumption building, fact checking, disclosures, and more.  I relayed my own wake -up call experience due to Al Zaehringer who was on the show several times years ago before he passed on.  Before the segment ended, Jim told us a story about the Wright Brothers and their Wright Flyer experience.  In our second segment, John Hunt called in to talk about Jim’s Space Shuttle comments.  This was a lengthy discussion with John, Jim, & John Jurist.  Jim talked about advantages with Saturn V including economic advantages over shuttle to LEO.  Subjects of reusability came up along with issues of getting a specific payload to orbit which our guests suggested advocacy often glosses over with facts and trades for payload mass fractions involved in reusability.  Dr. Logan brought up and discussed what he called NASA Brinkmanship Strategy.  Jim then talked about the reality of sending payloads to the ISS using shuttle.   Trent in Australia sent a message about magical thinking with Mars One.  Our last caller was Alan from St. Louis who said John and Jim were too negative in their discussion.  Alan then talked about using smaller rockets over heavy lift and was working to make the case that we have to work with what we have.  He also talked about evolving up from smaller, not starting off with the biggest.  Each of us responded to Alan.  It’s a discussion you do not want to miss.

Please post your comments/questions on either or both The Space Show Blog above or The Space Show Classroom blog, http://spaceshowclassroom.wordpress.com.  You can reach all of the participants including the callers through me at drspace@thespaceshow.com.

We welcomed back Dr. Marcelo Vazquez back to discuss space radiation and mostly human spaceflight to Mars though we covered much ground dealing with space radiation, the risk to humans, mitigation and shielding, as well as policy issues.  During the first segment of our 1 hour 38 minute program, we jumped right into it by my asking our guest about the radiation risks, exposure levels, and survival odds for both the Inspiration Mars mission and the Mars One effort to send settler to Mars on a one way mission starting late 2020 or 2021.  This was a detailed and comprehensive discussion of the issues for these missions, the state of the art shielding availability, possible technology advancements, and more.  We also talked about radiation & pregnancy on a Mars mission, radiation & a young child on Mars or in space, cosmic rays, solar events & extrapolations from radiation oncology.  Doug called to ask about the need for a solar storm shelter in case of a solar particle event. Before the end of the first segment, we talked about ISS analogs, antioxidants, and electromagnetic shielding possibilities.

In the second segment, Michael sent an article about the LRO analysis suggesting light weight materials and plastics might shield astronauts on the Moon.  Dr. Vazquez said this was in keeping with what was known.  Joel sent a note asking about RLIP76 and spaceflight, a subject on which our guest had much to say. Our guest went into detail about the radiation impact on a human system, including the destruction of blood vessels.  In this light, I asked him about radiation and epithelial cells & if this was a show stopper for HSF, especially to Mars.  Another question came in on antioxidants and while they might be helpful to some degree, they might also need to be taken at levels that are at or near toxic to humans.  Another listener asked about radiation & telomeres, then we talked about valid analog space radiation studies here on Earth.  I asked our guest about other nations doing HSF radiation research, then Jeff called in to discuss the Curiosity radiation findings and the regulatory questions involved since a person going to Mars would exceed the radiation dose allowed by existing OSHA & other regulations.  We talked about the validity of Inspiration Mars as a research study & as the program ended, we talked about neurological and cognitive radiation impact & some tests Inspiration Mars crews could do in this area on the mission.

Our program today was a 2 hour 5 minute Open Line discussion.  I started it out with some Space Show announcements, suggested topics for today’s discussion, then I opened the phone lines for listener participation.  Dr. Doug Haynes was our first caller. Doug is celebrating the tenth anniversary of Blue Ridge Nebula Starline (www.blueridgeairlines.com) and his sister site, www.bluenebula.com.  Dr. Haynes talked about his vehicles, missions, propulsion, AST, orbital, suborbital and all HSF, his issues with zero gravity, green space technology, spaceports with the Front Range Airport as well as Denver International. Follow our discussion about his vehicles and pods via his Blue Nebula website above.  Doug also told us about his books through the 3rd Wave Air Books which is linked to both his websites.  I did mention Doug’s very well known newsletter & how to visit his operation for those in and around the Denver area.  Our next caller was Dr. Doug Plata from Southern California to discuss space radiation and our Monday guest, Dr. Marcelo Vazquez.  Doug took us through several radiation risks and mitigation strategies.  We talked about radiation and the Mars missions plus what might & might not be appropriate regarding taxpayer money or the cash equivalent regarding helping a private company do a HSF to Mars.  Just before the break, questions came up about the upcoming SpaceX Falcon 9 Vandenberg launch.

In our second segment, Tim Weaver was our first caller to talk about Skylon.  There has been some recent press suggesting that the UK government my be interested in some funding with Skylon (www.sen.com/news/uk-pledges-fresh-support-for-revolutionary-space-engine.html).  We talked about the UK space interests and program along with the astronaut safety issue mentioned earlier and by Rand Simberg in his recent program.  John Hunt called in to talk about the Zubrin article on NASA’s asteroid retrieval mission, then he said he doubted anything would become of Skylon.  His last point pertained to astronaut safety per the Rand Simberg show and comments.  He suggested that since the government flies astronauts for national prestige, safety would be extreme given the potential prestige damage resulting from an accident.  Before the end, Doug sent in a note saying the Falcon 9 Vandenberg launch is currently set for Sept. 5th.

We welcomed retired Skylab astronaut Jerry Carr back to the program to discuss the Astronaut Scholarship Foundation (www.astronautscholarship.org) and the 40th anniversary of the Skylab space station.  Jerry the discussion with an overview of the Astronaut Scholarship Foundation, the STEM college scholarships it awards each year, auctions held to support the scholarship program as well as sales off the gift store on their website.  We then switched over to Skylab nothing that there will be a 40th anniversary celebration at KSC on July 27.  You can find out more about this celebration on the Astronaut Scholarship Foundation website.  I asked Jerry to describe for us one of his most memorable Skylab experiences and he talked about going into the command module flying over the Pacific and the views he saw as Skylab traveled in its orbit from Japan to the Pacific Northwest and more.  This is a great description of his view, don’t miss it.  Listeners asked Jerry multiple questions about Skylab, his experiences on board, comparing Skylab to the ISS and Skylab to the Mir.  We even talked about Skylab food and butter cookies, 0 g adaptation, close calls, and getting stuck in the center of Skylab.  Later in the segment, Jerry talked about consulting for space station human design factors for the ISS, then budget issues for Skylab as compared to NASA budget issues of today. We also talked about lessons learned throughout the program.  He was asked about inflatable commercial space stations & the time capsule they left on board when they departed the station.

In the second segment, a listener asked if the time capsule was recovered or could have survived reentry.  Another listener asked about the Skylab data still coming under analysis, then I asked about his public speaking engagements and if he could spot trends over time in terms people’s interest in space and science.  Jerry had much to say in response to several questions on this theme so don’t miss them.  Tony wanted to know about space radiation issues, Mars One, & artificial gravity with tethers.  Near the end, a listener brought up the recent interview with Rand Simberg and his space safety argument in his new book, “Safe Is Not An Option.”  We talked about risk taking, the mission, even risk taking landing on carriers and flying combat missions with the Marines.  He thought there might be too much risk averseness out of politically correct thinking but don’t miss all of his comments on this subject.  Our final topic focused on art with his wife Pat.  Check out their exhibit, OUR FRAGILE HOME at www.camusart.com.

We welcomed back Dr. Madhu Thangavelu for a 1 hour 45 minute discussion on a wide ranging set of topics from space visionary concepts to HSF to Mars, radiation and other issues, fantasy vs. reality thinking, and the synthetic mind. Madhu provided us with these links relevant to our discussion:  1. AIAA talk slides:
https://info.aiaa.org/Regions/Western/LA/Lists/Presentations/DispForm.aspx?ID=6 ; 2. AIAA Space Architecture panel video on YouTube : www.youtube.com/watch?v=ig3FzB0bQnA, 3. USC Space Concepts Studio website : http://denecs.usc.edu/hosted/ASTE/527_20111, 4. latest USC Eng. magazine carries an article, p16-17: http://viterbistorage.usc.edu/Public/USCVITERBIMAG.pdf.  In our first segment, Madhu opened up by talking about students and space inspiration.  Based on his own USC teaching experience, he said students were fired up.  Our guest was asked to compare robotic missions to HSF missions and Madhu spent some time on this discussion.  He also talked about the NASA plan to capture an asteroid, referring to this as a possible wild goose chase.  He talked about the ISS and using it more and more to accomplish important space goal.  Madhu received several questions about Tito’s Inspiration Mars flyby mission.  Here, he had much to say, especially about radiation, deep space communications, food & nutrition, and even physiology degradation.  We talked about using nuclear propulsion for such a mission & he suggested a better mission profile using two Falcon rockets.

In the second segment, Paul asked about using nuclear electric propulsion as compared to the two Falcon rocket idea. Madhu talked about the nuclear propulsion history with NERVA & the use of nuclear fuel on many of our robotic missions. Michael called in and said there was no real political will for nuclear so it probably would not happen anytime soon.  Later, Madhu was asked many specific radiation questions regarding the Mars flight.  Madhu suggested possible mitigation strategies, including his favorite, self cellular repair.  Allison emailed in to inquire about his Studio students and how he holds the line from reality thinking as compared to Kool Aid thinking.  Madhu talked extensively about this issue, discussed the philosophy of idea generation, visionary thinking with some fantasy while at the same time being grounded in engineering, physics, financial and other subcomponents of the concept. Don’t miss this important discussion.  We also talked about disruptive technologies.  At the end, we talked about the synthetic mind.

Guest:  Bas Lansdorp of Mars One.  Topics:  The Mars One mission, a comprehensive discussion.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://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.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information.  We welcomed back Bas Lansdorp, CEO of the Mars One project located in Holland.  For more information, visit their website www.mars-one.com.

During the first segment of this 94 minute program, Bas took us through the basics of the Mars One concept and mission.  I asked him for clarification as to their company structure given some of the newsletters from last year regarding converting from a for profit to a nonprofit organization.  During the discussion, Bas fielded numerous email listener questions addressing a long list of issues relevant to the Mars One mission.  For example, we talked about why a one way mission, the flight time and launch windows for Mars, radiation, the differences with ISS and Mir crews in LEO as compared to going through the Van Allen Belts and entering deep space with cosmic radiation and possible solar flares.  Bas talked about using 25-40 CM of water shielding.  We talked about the psychological/emotional health of the crew, growing food on Mars, livestock, and a Martian greenhouse.  Resupply from Earth came up & we inquired about the need for Earth resupply as compared to being Martian self-sufficient, plus other life support issues.  Mars One plans on sending cargo missions and supplies to Mars well in advance of the first human mission so Earth resupply may not be what is needed.  Another listener asked Bas about the planetary protection rules and if Mars One was up on them. Bas said yes and appears to be supportive of planetary protection efforts & regulations.

In our second segment, I asked him about his PR given that Mars One gets so much positive PR.  Crew selection questions came in & Bas said the most important qualification for the crew would be to get along in groups.  They plan on teaching the crews all the needed skills so they do not have to select engineers, doctors, etc.  He said that when they hire the first crew, it will undergo the comprehensive training for the mission over 7 years.  Bas got questions about the costs and using a reality TV model for funding purposes.  Bas corrected the listener as their model is the Olympics, not a reality TV show.  Another listener wanted to know about the possibility of their being denied an FAA launch license.  Still another set of questions came in about a Mars One failure leaving an unsupported colony on Mars.  Bas had much to say about this issue so don’t miss his comments.  We also talked about nations implementing the Astronaut Rescue Treaty if Mars One went under & there was no other company in its place.  More was said about the applicants, about 80,000 so far.  He told us most want to go to do something useful to improve humanity and the world. Going because you are unhappy on Earth or something like that will not get you accepted as a Mars One crew member.  Bas said he would be at two upcoming California events for those wanting to meet him, the Space Tech Conference in Los Angeles (www.spacetechexpo.com/conference-program-2013) and ISDC at the end of May in San Diego (http://isdc.nss.org/2013).

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information. We welcomes Dr. Roger Launius back to the program to discuss his latest book, “Coming Home: Reentry and Recovery from Space” which is a free download at www.nasa.gov/pdf/695726main_ComingHome-ebook.pdf. During our first segment, our guest provided us with a short history of resolving challenges with reentry from space with human spaceflight.  We discussed winged vehicles and capsules from a historical, practical, and engineering perspective.  We also talked about DOD influence and the advantages as well as disadvantages of both types of space vehicles.  One listener question asked about winged vehicles evolving from suborbital to orbital HSF.  Terry called in with ballistic reentry questions about the V2 rocket & we mentioned museum locations where people can see a complete V2 on display.  Another listener wanted to know if there were any winged vehicle concepts for Mars. Here, our guest talked about some science fiction examples but nothing for real on the drawing board.  Our guest then introduced us to magical thinking and we talked about reality in space exploration as compared to fantasy.  As this segment was ending, we talked about RLVs and reentry issues.

In our second segment, we started off talking about the NASA budget and the potential impact of sequestration.  Our guest said human spaceflight is the biggest challenge and in fact at one point he said we were just one banana peel away from losing HSF!  This was in the context of access to the ISS with only the Soyuz and how fragile the access was until we had multiple ways of getting to the station.  We then discussed risk and some of the issues raised on this subject by other Space Show guests that believe we need more risk to advance human spaceflight. Risk was also discussed in the context of hypothetical ISS recue missions with HSF vehicles not yet ready for prime time. We also talked about the value and purpose of HSF, including should settlement really be the purpose of it.  We had a lengthy discussion on this subject. Both Roger and I suggested the purpose of HSF is a challenge, can be illusive, and is probably something larger and broader than space settlement.  Don’t miss his explanation behind his thinking.  We also talked about spinoffs as a reason for HSF, the we addressed the lack of needed infrastructure, radiation issues, etc.  Toward the end, we took some questions about SLS and heavy lift.  Jane asked our guest about the visitors to the Air and SpaceMuseum at the Smithsonian & if Roger could infer an increase or decline in the interest in space by the visitors or if the visitors had an awareness of the challenges facing NASA and HSF.

Erik told us how to join up, the difference with Flight Members and Associate Members, what the flight qualifications consist of, and how they envision their role in flying citizen science experiments on the upcoming suborbital flights.  While we did mention orbital flights, Erik said the difference was significant with suborbital and for now the focus was completely on suborbital.  As you will hear, the book is much broader than the organization as he goes into many of the human factors impacting HSF, both on the suborbital level and the orbital level.  His book addresses the leading companies in the industry, NASTAR training for suborbital astronauts, and forward looking potential commercial space businesses.  One of the issues that can negatively impact suborbital human flight is space sickness and Erik spoke about this in some detail.  He also talked centrifuge training and G-forces on launch as well as the reentry. Near the end of the program, we talked about suborbital vehicle safety, launch abort, and crew escape.
