Let me end with an explanation of why I believe the move into space to be a human imperative. It seems to me obvious in too many ways to need listing that we cannot much longer depend upon our planet's relatively fragile ecosystem to handle the realities of the human tomorrow. Unless we turn human growth and energy toward the challenges and promises of space, our only other choice may be the awful risk, currently demonstrable, of stumbling into a cycle of fratricide and regression which could end all chances of our evolving further or of even surviving.
Gene RoddenberryStar Trek was an attempt to say that humanity will reach maturity and wisdom on the day that it begins not just to tolerate, but take a special delight in differences in ideas and differences in life forms.
Gene Roddenberry'Star Trek' is a 'Wagon Train' concept - built around characters who travel to worlds 'similar' to our own, and meet the action-adventure-drama which become our stories. Their transportation is the cruiser 'S.S. Yorktown,' performing a well-defined and long-range Exploration-Science-Security mission which helps create our format.
