Neil Armstrong in 1969, pasind pe Luna, intr-o perioada aflata in plin Razboi Rece:
“That's One Small Step For Man, One Giant Leap for Mankind”.

“Once again we have achieved a historic first. The United States is the first nation to reach Pluto, and with this mission has completed the initial survey of our solar system, a remarkable accomplishment that no other nation can match.”
