Guests: Rand Simberg and William (Bill) Simon returned for this Space Show program to discuss Evoloterra, the ceremony honoring when we first set foot on another world. Please visit www.evoloterra.com to learn more about this ceremony and to download it. During our discussion, Rand and Bill explained the origins of Evoloterra and its purpose. We discussed many related aspects of it, including the exploration spirit.

Guest : Dan Linehan, author of "SpaceShipOne: An Illustrated History," was the guest for this Space Show program. We went through the book, which is a documentary on SpaceShipOne (SS1), its development, construction, and flights. During this show interview with Dan Linehan, we address many things and learn lots of new things regarding SS1. For example, the rumor that it was unsafe to fly again and thus off it went to the Smithsonian, as you will hear in the story near the end of the discussion, is not true.

Guest: Dr. George Nield, Associate Administrator for the FAA Office of Commercial Spaceflight, was the guest for this program. Please note that there is audio noise on this recording coming from the hotel phone line. I apologize that a better quality connection was not available. We began our discussion with a tribute to Apollo 11 landing on the Moon given today being July 20. Dr. Nield gave us a good overview and comparison of the evolution of aviation as compared to the evolution of spaceflight. You will not want to miss this part of our discussion.

Guest: Dr. Pat Patterson returned to The Space Show to discuss this year's SmallSat conference from August 11-14 in Logan, Utah (www.smallsat.org). Dr. Patterson started out with a general description of the conference and provided us with an update with what is new from last year's conference. We then addressed the programming, specifically the keynote speak from ATK Systems, plus the panels, the audience participation programs, the award opportunities for students and much more.

Guest: Dr. Jim Logan was the guest for this Space Show program. Dr. Logan kicked off the discussion with a reality check of the body of evidence that we have accumulated during the 47 years of human space flight. He talked about two major potential showstoppers, micro/hypo gravity and radiation. As we discussed during the show, we know quite a bit about these two areas, but we do not yet have a solution for the problems they create for long-term human spaceflight or settlement. Dr.

Guest: Robert Zimmerman returned for this Space Show program. In addition to our discussion, we talked about Bob's new book about Hubble, "The Universe in a Mirror," and his terrific older book, "Leaving Earth." We started the interview by discussing a recent Washington Post article in which the author suggested the ISS be used as a spaceship for going someplace interesting rather than just hanging out in LEO. Mr. Zimmerman wrote about this idea years ago in his famous book, "Leaving Earth," so we talked about the feasibility of actually doing something like this with the station.

Guest: Eva-Jane Lark was the guest for this special Space Show program. Given Eva-Jane's financial and investment expertise (see her website bio below), we began our discussion with the historic approach used to finance major exploration efforts, eventually moving forward in time and extrapolating to space. Ms. Lark has a terrific paper on this subject which I am able to send to listeners, or since it is available on the web, you might find it using Google.

Guest: William Watson, Executive Director of The Space Frontier Foundation, was the guest for this special program to discuss the important upcoming NewSpace 2008 Conference, July 17-19, 2008 at the Doubletree Hotel, Crystal City, Virginia (please see their website www.space-frontier.org/Events/NewSpace2008/).
