The Moon's jagged horizon in the 1968 Earthrise photo, and the Earth's place beside it, only look like that from one spot on Apollo 8's path, and that spot gives away the moment. Claude traced 2,781 points along the horizon, matched them against lunar elevation data, and worked out the time and place: 16:39:39 UTC on Dec. 24, 1968, about 69 miles above the Moon. Then it rebuilt the scene in 3D and blinked it against the original. Photo: NASA, Apollo 8 frame AS08-14-2383 (film scan: NASA/JSC/Arizona State University).
