You can order this book and find out more about it by visiting his website, www.rocketengineer.bravehost.com/. During Segment 1, Dave talked about the need for space engineering and rocket education, how his book fills this need, and what it means for future engineers in all disciplines, not just those related to space. He focused on the nuclear industry in his engineering examples. In Segment 2, we talked about more specifics, engine gimbling, guidance technology, subsonic flight as well as supersonic rocket flight characteristics. In Segment 3 which was extended by half an hour, we talked about the use of nuclear power for space and went into some detail about NERVA and VASIMIR, and radiation issues.
