That Christmas Eve message from Apollo 8 is still one of the most moving moments from the entire space flight endeavour.
Frank Borman got the idea from a friend and loved it. He took it to Jim Lovell and Bill Anders and took them a short second to agree to the idea. When they got back, Madldyn Murray O’Hare tried to sue the crew and NASA for mixing religion and government. She lost that case, badly.
Years later, I got to see the original flown flight plan that had the Genesis reading in it. That was special. The Apollo 8 command module is in the Museum of Science and Industry in Chicago.
