And if any of you were alert and coherent during the 1960s -- and we'd forgive you, if you weren't, OK -- you would remember this very famous picture taken by the Apollo 8 astronauts in 1968.
Om några av er var klara i skallen på 1960-talet... Ni andra är förlåtna. Om ni var det skulle ni minnas den här bilden. Den togs av Apollo VIII 1968.
