Since, in the long run, every planetary civilization will be endangered by impacts from space, every surviving civilization is obliged to become spacefaring–not because of exploratory or romantic zeal, but for the most practical reason imaginable: staying alive… If our long-term survival is at stake, we have a basic responsibility to our species to venture to other worlds.That’s one small step for [a] man; one giant leap for mankind.The powered flight took a total of about eight and a half minutes. It seemed to me it had gone by in a lash. We had gone from sitting still on the launch pad at the Kennedy Space Center to traveling at 17,500 miles an hour in that eight and a half minutes. It is still mind-boggling to me. I recall making some statement on the air-to-ground radio for the benefit of my fellow astronauts, who had also been in the program a long time, that it was well worth the wait.
