During the first segment of our 1 hour 33 minute program, Charles and Ed talked with us about the Microlaunchers concept and how that concept is depicted in the book. We also learned how Charles and Ed met and the role each had in writing and completing this book. Our first caller Jeff from Tucson won the give away copy of the book. Jeff also asked our guests about the role of cubesats in the Microlaunchers concept specifically for LEO and then GEO. This led to Charles talking with us about secondary payloads and why he does not favor them. Charles & Ed then described some of the Microlaunchers launch parameters, then we took a question from Paul in Boston who wanted to ask about market concerns for the Microlauncher concept. Doug from S. California was the next caller with three specific issues to raise with our two guests. We also talked about payload mass and the path to a larger system, including the GEO market. As the segment ended, Charles put forth his payload pricing goals for his system. In the second segment, we started out with Ed describing the organization of the book into three main sections. Next, our guests fielded questions about propulsion. Charles said they were using a bi-propellant fuel consisting of liquid propane and liquid oxygen. Hardware issues were also discussed and our guests raised issues of how to get more awareness and visibility for their concept. The last call came from Nels in London as we were about to end the show. Nels wanted to know about the trades considered and used regarding the fuels and the propulsion systems our guests talked about during the program. Both our guests left us with closing comments you will want to hear. Please post your comments/questions on TSS blog. You can reach our guests through the Microlaunchers website or through me.
