"Our current exploration of space makes the point vividly: Here is testimony to man's vision and to man's courage. The journey of the astronauts is more than a technical achievement; it is a reaching-out of the human spirit. It lifts our sights; it demonstrates that magnificent conceptions can be made real. They inspire us and at the same time they teach us true humility. What could bring home to us more the limitations of the human scale than the hauntingly beautiful picture of our earth seen from the Moon?"
