* Do not go gentle into that good night; Old age should burn and rave at close of day. Rage, rage against the dying of the light.

* We've always defined ourselves by the ability to overcome the impossible. And we count these moments. These moments when we dare to aim higher, to break barriers, to reach for the stars, to make the unknown known. We count these moments as our proudest achievements.

*Murphy's law doesn't mean that something bad will happen. It means that whatever can happen, will happen.

* We're still pioneers, we've barely begun. Our greatest accomplishments cannot be behind us, cause our destiny lies above us.

I'd like to point out that, for those who don't know, this is not an original quote from the movie, but is actually a villanelle by Dylan Thomas.
Nevertheless, they used it perfectly in the movie. And all the quotes are brilliant.

I say none of the above. I liked the early quote of "We used to look up at the sky and wonder our place in the stars. Now we look down at the ground and wonder our place in the dirt."
