We welcomed the final 2011 Open Lines program. During our two hour discussion with one break, I outlined discussion topics up front but as you will hear, one topic struck home. Listeners wanted to talk about the New Scientist interview with Elon Musk entitled "I'll Put Millions of People on Mars, says Elon Musk." You can read the full interview on The Mars Society website, www.marssociety.org/home/press/news/illputmillionsofpeopleonmarssayselon.... Callers honed in on the reported development costs for the Mars spaceship ranging from the $2-$5 billion. Those that called the program thought this was inadequate funding. At one point I looked up the development costs for the Boeing 787 Dreamliner which so far was estimated at $32 billion. Since all of us thought a Mars spaceship was more complicated and involved in R&D than a new Boeing jetliner, listeners seemed to be more convinced that the projected costs were too low. One listener brought up the costs of military projects such as the F22, the JSF, nuclear powered carriers and submarines, etc. Another listener wanted to know if Space X was planning to open up additional launch sites to those that are publicly known. In the second longer segment, not only did the military hardware come up for cost comparisons, but John in Atlanta wanted to talk about the Space News Op-Ed by Christopher Kraft (http://spacenews.com/commentaries/111219-nasa-needs-wake-reality.html). Mr. Kraft wrote about the need to internationalize projects and make use of publicly available international hardware rather than build the SLS. Tim called in from Huntsville to talk about the Musk interview, the rocket development costs, and using space resources to lower the costs. He even suggested Elon make use of the QuickLaunch idea to put lox/kerosene in orbit for refueling. Dr. Jurist called in to talk about the human factors for a Mars mission and that they seem to be understated by the Mars advocates. Dr. Jurist speculated that it might take 5-10 years just to be able to address most of the human factor issues, not including what might be involved in implementing solutions. We then talked about Stratolaunch and air launch. We talked about the small payload capacity of the proposed vehicle and the need for multiple flight depending on the mission and the needed total payload. Our next topic was yet another Soyuz failure and what this might mean for the ISS if the Soyuz problems are not fixed. Terry called in again from Corpus Christi to talk about the Falcon 9 & Dragon flight in early February and how the success of the flight might become a driver for more commercial crew funding from the government. With Dr. Jurist, we also explored the idea of inviting a certain UC Davis aerospace engineering professor to the program to discuss horizontal versus vertical launch and reusability. I concluded this program with my own wish list for more civility within our space advocacy family and for real leadership with responsibility and accountability to emerge at all levels in Washington, DC, not just for space, but for the future of our nation.
