Fifty years ago on Christmas Eve (December 24, 1968), the crew of Apollo 8 entered lunar orbit and began circling the moon — the first time in history for humans to visit another world.
That evening, the crew’s astronauts Bill Anders, Jim Lovell, and Frank Borman, transmitted a live television broadcast including spectacular pictures of the moon just 60 miles below them, and of the Earth — a quarter of a million miles away.
