Alfred Worden quotes:

Now I know why I'm here. Not for a closer look at the moon, but to look back at our home, the Earth.

Quietly, like a night bird, floating, soaring, wingless. We glide from shore to shore, curving and falling but not quite touching; Earth: a distant memory seen in an instant of repose, crescent shaped, ethereal, beautiful, I wonder which part is home, but I know it doesn't matter... the bond is there in my mind and memory; Earth: a small, bubbly balloon hanging delicately in the nothingness of space.
