Fifty years since JFK's call was realized-
" . . . this nation should commit itself to achieving the goal, before the decade is out, of landing a man on the Moon and returning him safely to the earth."
And one of my favorite lines from his speeches-
"We choose to go to the moon. We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too."
