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 Space Museum 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.
