Today, we are on a path of decay. We are seeing the book close on five decades of accomplishment as the leader in human space exploration.

If the guidance failed or started to stray or went somewhere we didn't like or the ground didn't like, I could flip a switch, and I could control seven, over seven and a half million pounds of thrust with this handle and fly the thing to the Moon myself.

OK, let's get this mother out of here.

When you head on out to the Moon, in very short order, and you get a chance to look back at the Earth, that horizon slowly curves around in upon himself, and all of sudden you're looking at something that is very strange, but yet is very, very familiar, because you're beginning to see the Earth evolve.

Some astronauts describe the routine flushing of urine into space, where the freezing temperatures turn the droplets into a cloud of bright, drifting crystals, as being among the most amazing sights they saw on an entire voyage.

I'm quite disappointed that I'm still the last man on the moon.

We leave as we came, and, God willing, as we shall return, with peace and hope for all mankind.
