Guest: Dr. John Jurist: Topics: Marine Corps SUSTAIN Project, winged suborbital vehicle, suborbital tourism, point to point space transportation, US Space Policy, and UND Space Studies. Dr. John Jurist joined us to talk about the Marine Corps SUSTAIN project, which wants to be able to deliver a fully equipped Marine squad anywhere in the world within two hours. Dr. Jurist talked about some of the ways this would be possible, the physics, orbital dynamics, engineering, and costs involved in such a project, as well as the type of space policy that would be needed to see such a program developed. Questions came in about SUSTAIN being a space weapon and there was quite a discussion about weapons in space, including side arms on the Soyuz, shuttle and the ISS. Thanks to several listeners, we found out that side arms are aboard the Soyuz, although we do not know about the shuttle or the ISS. I suggested that such weapons would likely be opposed by most people, even in a survival kit for use back on Earth. If you have comments about this one way or the other, let us know. In addition , Dr. Jurist also talked about the energy needed to do a SUSTAIN mission, suborbital tourism vehicles and winged suborbital vehicles. You will want to hear what he has to say about these various vehicle types, their capabilities, and their mission profiles. Toward the end of the show, he was asked about the UND Space Studies program being a good base for a career in space medicine. Dr. Jurist talked about space medicine programs in general and we discussed multidisciplinary space studies programs and the space policy reports calling on an improvement in space leadership, management, and organization which opens the doors to a good space studies program which addresses the areas that the reports highlight as a need for the nation. If you have any questions or comments for Dr. Jurist regarding SUSTAIN or other discussion topics on this show, please send them to me at and I will forward them to him.
