Guest: Open Lines with DrSpace. Dr. David Livingston (DrSpace) conducted an Open Lines show for this Space Show program. The theme for this show was a look back at the seven years of programming with more than 1,000 shows. In the process of sharing my reflections on trends, changes, and strong and weak points of the space industry, we had lots of callers and online questions. We covered many topics ranging from educational issues, to business planning and due diligence to hard core engineering and scientific analysis of ventures and rhetoric often heard in the industry.

Guest: Rand Simberg, who blogs at Transterrestrial Musings (www.transterrestrial.com/), was the guest on the show. Rand recently wrote an article about the possible space policies from each of the three leading American presidential candidates and we wanted him to talk about his views on this subject right here on The Space Show. This was a comprehensive discussion on space policy, not just the possible policy of each of our presidential candidates, and you will find this information most valuable.

Guest: Dr. Robert Conger was the guest for this Space Show program to discuss the upcoming Responsive Space Conference, April 28-May 1, 2008 at the LAX Westin Hotel, Los Angeles, California. Dr. Conger started out with a definition and explanation for the term "responsive space", then later he did the same for operationally responsive space.
