Guests: CLASROOM: Dan Adamo and co-hosts: Topics: Lesson 3: Orbital/Flight Dynamics. Lesson 3 discussed the basics of orbital and flight dynamics over a two hour plus period.

Guest: Rick Tumlinson. Topics: Space frontier development, private/public partnerships, Augustine Commission. Rick Tumlinson returned for this special two hour Space Show program. Each segment was one hour but an overriding theme went through the entire show. This theme was the need to develop the space frontier and that the private sector could do it, that the government civil space program should address space exploration from LEO and beyond, but Earth to Leo should be turned over to the private sector companies. As Rick said, NASA should buy the ride, not the rocket.

Guest: Mark Hempsell. Topics: Reaction Engines, Ltd., SKYLON, special heat exchangers, low cost space access. We welcomed first time guest Mark Hempsell.
