The webinar can be viewed at We welcomed Dr. Jurist to this special two hour webinar on rocket mission, planning, risk, & cost analysis. Dr. Jurist developed a series of copyrighted spread sheets for this discussion. Callers had the opportunity to "massage" the numbers to see what happened with costs, success probabilities, & how many launches might be needed depending on the rocket being evaluated. We relied upon published data for all rocket systems discussed, even when only theoretical. Much of the discussion during this webinar focused on comparisons of Falcon 9, Falcon Heavy, SLS, and the Liberty Launch Vehicle. We also used a Falcon 1e as a baseline for comparison. Dr. Jurist and the callers planned missions to LEO and the ISS, the Moon, and Mars. We also looked at costs of total payloads delivered into LEO as a function of launch vehicle reliability and cost for multiple launches into the same position in LEO. Even with our two hour discussion, we did not get to cover several spreadsheet pages that rough out launch vehicle configurations and costs as a function of payload and total production runs. We will cover more of this material in the upcoming parts of this webinar series through early next year. Dr. Jurist addressed questions dealing with simultaneous launches and third party depot operations including fuel sales and space tug services. Some other subjects were also discussed in the webinar including the recent high altitude jump by Felix Baumgartner and combating the spin. We also talked about the recent statement made by Felix about not spending money on Mars missions in favor of saving the Earth. Please post your comments & questions on The Space Show blog. Dr. Jurist and I will respond to your blog posts. If you want to talk to Dr. Jurist about his spreadsheet and your possible use for it, you can email him at
