Now, more than ever, we need people in space... The events of September 11 show us how vulnerable we and our civilization are down here on Earth... So let us use our strength, our awareness of mortality as a civilization, to do something truly lasting and earth-shaking for humanity. Let us join with the peoples and cultures of this planet, the diversities of its perspectives and religions and science, so we can leave it-not behind, but as a springboard to something better.
