Guest: Norman J. Gerstein was the guest for this special Space Show program. Mr. Gerstein was deeply involved in Rover/NERVA and we discussed these programs in detail. He was part of the KIWI-TNT team and involved in the cleanup by picking up the debris with a wheelbarrow and tongs. Norm described these programs in detail along with the nuclear rocket which we compared to chemical rockets. Norm made it very clear that one needs a mission to do these programs. Another way of saying it, is to make sure there is a need. Since there was no need (no mission), the programs were cancelled.

Guest: Winston E. Scott (Capt. USN Ret.), former NASA Astronaut, returned for this Space Show program to discuss his "Win An Afternoon with Winston E. Scott, The Astronaut" contest. When a school buys his book, "Reflections From Earth Orbit", they enter the contest to win Capt. Scott for an afternoon. Capt. Scott will come to the school to talk with the students about space. Parents, grandparents, and others can buy and donate his book to the school and enter the school in the contest. The contest ends Oct. 31, 2008.

We started our discussion with the basics of the space elevator concept and why at this point in time convergence is necessary for the space elevator's development. Our two guests covered these issues in some detail and then more when listeners starting asking about why we need a space elevator.

Guests: Brian Mosdell, followed by Bill Dowdell and Jon Cowart. Brian Mosdell is the Director of Florida Launch Operations for SpaceX.
