“It’s hard to appreciate the Earth when you’re down right upon it because it’s so huge. It gives you in an instant, just at a position 240,000 miles away from it, (an idea of) how insignificant we are, how fragile we are, and how fortunate we are to have a body that will allow us to enjoy the sky and the trees and the water ... It’s something that many people take for granted when they’re born and they grow up within the environment. But they don’t realize what they have. And I didn’t till I left it.”
—Jim Lovell, Apollo 8 and 13.
“...From up there, it looks finite and it looks fragile and it really looks like just a tiny little place on which we live in a vast expanse of space.”
—Winston Scott, two-time shuttle astronaut
“I left Earth three times. I found no place else to go. Please take care of Spaceship Earth.”
—Wally Schirra, who flew around Earth on Mercury, Gemini and Apollo missions in the 1960s.
