Today is the 40th anniversary of the Apollo 11 moon landing. It is not often told, but one of the first things Buzz Aldrin did after landing on the moon was to take communion. He originally planned to quote scripture (John 15:5 - "I am the vine and you are the branches..."). He was asked by NASA not to do this because they were involved in a legal dispute with Madelyn Murray O'Hare. So Aldrin simply asked for a moment of silence, and then privately gave thanks to God.
