The late adventure photographer Galen Rowell called it "the most influential environmental photograph ever taken." Captured on Christmas Eve, 1968, near the end of one of the most tumultuous years the U.S. had ever known, the Earthrise photograph inspired contemplation of our fragile existence and our place in the cosmos. For years, Frank Borman and Bill Anders of the Apollo 8 mission each thought that he was the one who took the picture.
