Guest: Paul Breed. Topics: Lunar Lander Challenge (LLC), rocket technology, space vision and policy. We welcomed Paul Breed back to The Space Show to discuss his recent LLC experiences. We started our first segment with Paul giving us an update as to this year's LLC and the Unreasonable Rocket effort to win both phases, the 90 second and the 180 second phase. You can learn more about his efforts and work at his blog and website, http://unreasonablerocket.blogspot.com.

Guest: Jim Crisafulli. Topics: Hawaii commercial spaceport, aerospace development and commerce. We welcomed Jim Crisafulli, Director of the Hawaiian Office of Aerospace Development to the show. In our first segment, we focused on Hawaii's plan to develop a commercial spaceport to service spaceplanes for space tourism. We learned that Hawaii is in the process of preparing for an environmental assessment regarding expanding the usage of several of their commercial airports to include the horizontal takeoff and landing of a spaceplane.

Guest: Dr. Jim Vedda. Topics: Space policy and goals. We were most fortunate to have as our guest for this program, Dr. Jim Vedda. Our two hour discussion was wide ranging over many aspects of both U.S. and global space policy. In our first segment, Dr. Vedda talked about the "why" of space policy in the final chapter of the Augustine Commission Report but suggested this information relating to the goals of our space program should have been at the front of the report given its importance. This opened up our discussion on space goals being about our capability, not a destination.

Guest: Edward McCullough. Topics: Advanced technology, launch vehicles, space and lunar solar power. As we started our first segment of tonight's program, we focused on launch vehicles and Ed said up front that the launch vehicle companies must be profitable. With insufficient flights and fewer and fewer flights, it's hard for them to be profitable but were we to build and deploy a space solar power system, that would change things.

uests: Dr. Ted Bateman, Dr. Jeff Willey. Topics: Microgravity environment of space and bone loss in astronauts due to radiation. Our guests for today, Dr. Ted Bateman and Dr. Jeff Willey, both of Clemson University, are involved in bone loss studies at the radiation levels astronauts will probably encounter on long duration spaceflights, space settlement, and possibly even on a flight to Mars. Their research flows from a project funded by the National Space Biomedical Research Institute (NSBRI) in Houston.

Guest: Mel Marsh: Topics: Informed consent, space tourism, minor children, technology evaluation, anthropology, and astrosociology. Mel Marsh returned to The Space Show for this program. In the first segment, we focused on Mel's paper, "Ethical Issues Regarding Informed Consent for Minors for Space Tourism." You can find this paper and more of Mel’s work at his website: www.melsmarsh.com .

Guests: Dr. Robert (Bobby) Braun, Robert (Rob) Manning. Topics: Entry and descent for landing large Martian payloads. Our guests for this program, Dr. Bobby Braun and Rob Manning, are conducting research on how to land large payloads on Mars. Their paper, "Mars Exploration Entry, Descent and Landing Challenges" was prepared for the IEEAC, #0076 in December 2005. I strongly recommend that you obtain a copy of this paper and read it. Dr. Braun's website for the Space Systems Design Lab at Georgia Tech University is www.ssdl.gatech.edu/.

Guest: Douglas Mallette. Topics: space exploration for humanity, space vision, talking to the non-space community. Douglas Mallette was our guest for this show to talk about his new book, "Turning Point: How Space Exploration and Development Will Determine the Rise or Fall of Humanity." This book is available on the One Giant Leap Foundation Amazon partners book page, http://www.amazon.com/dp/0557091233?tag=onegialeafou-20.
