Welcome aboard and thanks for the post. I can remember reading about project Rover when I was a kid. Too bad it was cancelled during the brain dead '70s! Anyway that report is a nice piece of work. We can sure use someone with your background on here.
Thanks very much for the link to the paper--and Welcome aboard, Jim! Project Rover and Project NERVA did some marvelous work--and the foundations they created will help boost us across the solar system one day.
I downloaded a copy of your paper, and after i get my daughter to school, I look forward to studying it!
