Undoubtedly, the quote most associated with the moon landing is Neil Armstrong's iconic line, "It's one small step for man, one giant leap for mankind." But those weren't the only famous words spoken on July 20th, 1969. About 30 minutes before Armstrong took his first lunar steps, he coined another phrase that would prove to have lasting impact: "Houston, Tranquility Base here. The Eagle has landed." ("Eagle" is capitalized because it refers to a literal part of the spacecraft - the lunar module that transported Buzz Aldrin and Armstrong to the moon.) Today the phrase is used to describe the arrival of pretty much anything - or anyone - of note.
With those words, the dream President John F. Kennedy's voiced in 1961--putting humans on the Moon by the end of the decade--had at last come true.
From the launch on July 16 atop a powerful Saturn rocket, Apollo 11 and its crew of three astronauts performed flawlessly. While Michael Collins orbited the Moon in the Command Module, Armstrong piloted the Lunar Lander, named the Eagle, to a safe landing in the Moon's Sea of Tranquility. He and his copilot, Edwin "Buzz" Aldrin, soon became the first humans to tread on another world. They spent nearly 21 hours on the lunar surface, collecting samples of rock and soil and setting up remote instruments.
