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.

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.
