We travel together as passengers on a little spaceship, dependent on its vulnerable reserves of air and soil; all committed for our safety to its security and peace; preserved from annihilation only by the care, the work, and I'll say the love we give our fragile craft. We cannot maintain it half fortunate, half miserable, half confident, half despairing, half slave to the ancient enemies of man, half free in liberation of resources undreamed of until this day. No craft, no crew can travel safely with such contradictions. On their resolution depends the survival of us all.
