Neil Armstrong Quotes

Astronaut Neil Armstrong, who lived from 1930 to 2012, is widely regarded as an American hero. His bravery and skill earned him the honor of the first human to ever set foot on the Moon. As a result Neil Armstrong has been looked to for insight into the human condition as well as commentary on the state of technology and space exploration. Here are some comments he made on everything to landing on the Moon to space travel in general.

"That's One Small Step For Man, One Giant Leap for Mankind."

His most famous quote is one that actually doesn't quite make sense since "Man" and "Mankind" have the same meaning. Neil Armstrong actually meant to say "... one small step for a man..." referring to himself setting foot on the Moon and this event having deep implications for all people. The astronaut himself mused that he hoped that the annals of history would analyze his words for what he meant to say during the Apollo 11 mission's lunar landing.

"Houston, Tranquility Base here. The Eagle has landed."

The first words Neil Armstrong said when the Apollo landing craft settled onto the surface of the Moon. That simple statement was a huge relief to the people at Mission Control, who knew he had only a few seconds of fuel left to complete the landing.

"I believe that every human has a finite number of heartbeats..."

The full quote is "I believe that every human has a finite number of heartbeats and I don't intend to waste any of mine." Some report that the phrase ended with "running around doing exercises." though it is unclear if he actually said that.

"We came in peace for all mankind."

In an expression of mankind's higher moral hope, Neil Armstrong stated "Here men from the planet Earth first set foot upon the Moon. July 1969 AD. We came in peace for all mankind."  Neil was reading aloud the inscription on a plaque attached to the Apollo 11 Eagle lunar module.

"I put up my thumb and it blotted out the Earth."

I can only imagine the view from the Moon. We become so accustomed to our view of the heavens, but to turn and see the Earth in all its blue glory; it must be a sight to see. This idea came to a head when Neil Armstrong found that he could hold up his thumb and completely block the view of Earth.

"...we're going to the Moon because it's in the nature of the human being..."

"I think we're going to the Moon because it's in the nature of the human being to face challenges. We're required to do these things just as salmon swim upstream."

"I was elated, ecstatic and extremely surprised that we were successful."

The complexity of traveling to the Moon is immense even by today's technology. But remember that the computing power available to the Apollo landing module was less than what you now have in your scientific calculator. The technology in your cell phone simply puts it to shame. In that context, it's still amazing that we were successful in putting people on the Moon.

"It's a brilliant surface in that sunlight."

"It's a brilliant surface in that sunlight. The horizon seems quite close to you because the curvature is so much more pronounced than here on Earth. It's an interesting place to be. I recommend it." As much as he could explain a place very few people have ever been, Neil Armstrong tried to explain this amazing place the best he could.

"Mystery creates wonder and wonder is the basis of man's desire to understand."

"Humans have an inquisitive nature, and that manifests itself in our desire to take that next step, to seek out the next great adventure."Going to the Moon wasn't really a question in Neil Armstrong's mind, it was the next step in the evolution of our knowledge, of our understanding. For him — and for all of us — going there was necessary to explore the limits of our technology and set the stage for what mankind could achieve in the future.

"I fully expected that... we would have achieved substantially more..."

"I fully expected that, by the end of the century, we would have achieved substantially more than we actually did." Neil Armstrong was commenting on his missions and the history of exploration since then. Apollo 11 was looked upon at the time to be a starting point. It was proved that people could achieve what many considered impossible, and NASA set its sights on greatness. Everyone fully expected that we would soon be off to Mars. The colonization was a near certainty, probably by the end of the century. Yet nearly five decades later, the Moon and Mars are still being robotically explored, and plans for human exploration of those worlds, plus the asteroids, are still being put in place.

Good Luck, Mr. Gorsky!

I'm including this bonus quote just to set the record straight. Neil Armstrong was rumored to have said this immediately following his famous small step for man quote. However, it was merely part of a humorous (and slightly naughty) joke and he never actually said it, even though it is widely attributed to him.
