William Anders and his crewmates James Lovell and Frank Borman became the first human beings to see the Earth as a sphere hanging in space. The photograph was taken 4 hours and 36 minutes after launch with the 80mm lens from about 27,000 km out in space.

The photograph graced the cover of Life magazine (The incredible year 1968; January 10, 1969).

“A striking view from the Apollo 8 spacecraft showing nearly the entire Western Hemisphere, from the mouth of the St. Lawrence River, including nearby Newfoundland, extending to Tierra del Fuego at the southern tip of South America. Central America is clearly outlined. Nearly all of South America is covered by clouds, except the high Andes Mountain chain along the west coast. A small portion of the bulge of West Africa shows along the sunset terminator” (original NASA caption for AS8–16-2593).

“To see the Earth as it truly is, small and blue and beautiful in that eternal silence where it floats, is to see ourselves as riders on the Earth together, brothers on that bright loveliness in the eternal cold—brothers who know now they are truly brothers.” Archibald McLeish (The New York Times, December 25, 1968).

From the mission transcript after translunar injection:

003:38:00 Lovell: Roger. Well, Mike, I can see the entire Earth now out of the center window. I can see Florida, Cuba, Central America, the whole northern half of Central America, in fact, all the way down through Argentina and down through Chile. 003:38:25 Collins (Mission Control): They picked a good day for it. [...] 004:06:36 Collins: How close to a radial burn can you get without losing sight of the S-IVB (booster), Frank? 004:06:41 Borman: Well, I don’t know because I can’t see the Earth now, Mike. [...] 004:06:51 Borman: We can pitch down some. Jim has the Earth in the optics so we could pitch some and get pretty close to one (a radial burn), I guess. [...] 004:17:11 Collins: Roger, Frank. You could help us out if you would explain where you are relative to the booster. In other words, with respect to the Earth and the radius back there, are you above or below or one side, or where exactly is the booster relative to you? 004:17:27 Borman: Well, it’s as I said before. We can’t definitely find the Earth. I think we are in front and a little bit above - a little bit above the - almost in front of the - directly in the front of the booster. [...] 004:36:00 Anders: Roger. If it will help you any, Mike, the Earth is plus-Y about 45 degrees in a minus-X. I can see it out my side window, and it’s a beautiful view with numerous cloud vortex. [...] 004:36:51 Anders: It’s behind us to the right, if that will help. 004:36:54 Collins: Roger. [Long pause.] 004:37:15 Borman: I can still see the Cape and isthmus of Central America.
