" If someone asked me to sum up what is great about my country, I would probably tell them about Apollo 11, about the four hundred thousand people who worked to make the impossible come true within eight years, about how it changed me to see the space-scarred Columbia capsule in a museum as a child, about how we came in peace for all mankind. "
