After orbiting the Earth twice, Apollo 8 fired the Saturn V third stage and broke free of Earth’s gravitational pull on a trajectory for the Moon. The photograph was taken with the 80mm lens after separation from the expended SIVB third stage.
“Already farther out in space than man has ever flown, Apollo 8’s crew at 3,500 miles gaze down on the shallow Bahama Banks (bottom of picture), turquoise against the darker, deeper Atlantic. Few clouds veil the southeastern coast of the United States and the West Indies (left of picture), but to the northeast a huge storm system swirls over the ocean. The spacecraft has now kicked out of Earth orbit toward the Moon” (National Geographic, May 1969, p. 609).
“The other thing [...] was that this particular spot, the Bahamas lowland, was a turquoise jewel that you could see all the way to the Moon,” observed William Anders. “It was like it was illuminated, like a piece of opal. And you could see that all the way. And I kept being amazed about that” (Chaikin, Voices, p. 26).
