But for all that the Apollo astronauts saw and did on the moon, it was their home planet that shocked them with its beauty. Bill Anders of Apollo 8 says the first Earthrise he saw nearly knocked him off his feet. "Because we were being trained to go to the moon... We were trained to get there. So, getting there was the big event." It wasn't 'going to the moon and looking back at the Earth.' I never even thought about that! In lunar orbit, it occurred to me that, here we are, all the way up there at the moon, and we're studying this thing, and it's really the Earth as seen from the moon that's the most interesting aspect of this flight."
