We welcomed Dr. Frank Martin to the program to discus the NRC human spaceflight study along with all aspects of human spaceflight including various destinations and missions. During the first segment of our 1 hour 39 minute show, Dr. Martin introduced us to the NRC Pathways study which you can download for free by using Google. He suggested it was a dose of reality as well as optimism. He said the study was very clear in saying “show me the money” for those wanting to do humans to Mars missions now or fairly soon and then explained some of the high costs and trades involved in these missions. One of his overriding themes throughout our discussion was the need to manage a very large mass in LEO in order to accomplish the goals of long duration human space mission. During our segment, we kept coming back to the need to manage a large mass in LEO and how this translated to costs as well as the need for technology advancement. Both myself and listeners asked our guest about doing human missions cheaper by using the private sector. This subject kept coming up during both segments of the program. We also addressed the rational for human spaceflight. In addition, the issue of walking away from HSF was looked at for the US as a nation as that is an option. The report attempted to address this and related issues. Joe sent in an email about the mice on the ISS and using them to determine the gravity RX for HSF. He sent us several additional emails on this subject as well. This prompted comments about the need to use the ISS for research in support of long duration HSF missions. Dr. Martin said Mars was an horizon goal. In this context, he talked about only a few other possible destinations near us, either the Moon or an asteroid. He then proceeded to address the issue of managing the risk for a Mars mission. Beverly asked a budget question and taking the lead from the most recent Mike Griffin interview, she asked Frank if it really was just a choice to be constrained by budget issues. While Frank agreed it was a choice, he said there were very good ways and choices to spend taxpayer money so he did not see significantly more money for space in the future. Another listener talked about nuclear propulsion which also crossed into the second segment. Near the end of the first segment, we got a call from a New Zealand listener. During his call, the idea of the Buzz Aldrin Mars cycler came up and there was a question or two about fuel depots.
In the second segment, I asked Dr. Martin why the study took 18 months, then SLS John called the program. John wanted to talk nuclear propulsion thinking it would be a cost saver but what was not known was the accurate cost of the R&D program or the cost for jumping through political hurdles. John suggested a new administration would make a difference and I challenged that. I asked Frank given all his years of space industry experience if it was reasonable to expect big changes in space policy due to a change in administrations. Don’t miss Frank’s reply. Dwayne called back to question the HSF rational. One of the points made by Dwayne was that cooperation with the Russians on the ISS does not modify Russia’s behavior other than for space.
