Here is one way to conceptualize NASA's heroic era: in 1961, Kennedy gave his "moon speech" to Congress, charging them to put an American on the moon "before the decade is out." In the eight years that unspooled between Kennedy's speech and Neil Armstrong's first historic bootprint, NASA, a newborn government agency, established sites and campuses in Texas, Florida, Alabama, California, Ohio, Maryland, Mississippi, Virginia, and the District of Columbia; awarded multi-million-dollar contracts and hired four hundred thousand workers; built a fully functioning moon port in a formerly uninhabited swamp; designed and constructed a moonfaring rocket, spacecraft, lunar lander, and space suits; sent astronauts repeatedly into orbit, where they ventured out of their spacecraft on umbilical tethers and practiced rendezvous techniques; sent astronauts to orbit the moon, where they mapped out the best landing sites; all culminating in the final, triumphant moment when they sent Neil Armstrong and Buzz Aldrin to step out of their lunar module and bounce about on the moon, perfectly safe within their space suits. All of this, start to finish, was accomplished in those eight years.

Only since the collapse of the Soviet Union have we learned that the Soviets were in fact developing a moon rocket, known as the N1, in the sixties. All four launch attempts of the N1 ended in explosions. Saturn was the largest rocket in the world, the most complex and powerful ever to fly, and remains so to this day. The fact that it was developed for a peaceful purpose is an exception to every pattern of history, and this is one of the legacies of Apollo.

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.

Histories of the Kennedy Space Center acknowledge without exaggeration that the obstacle posed by the mosquitoes was so serious that NASA quite literally could not have put a man on the moon by Kennedy's "before the decade is out" deadline without the invention of DDT. In this way, the challenges of spaceflight reveal themselves to be distinctly terrestrial.
