Four days shy of the photo's 45th anniversary, NASA on Friday (Dec. 20) released a new simulation of the eventsÂ that led to the creation of the image known as "Earthrise." The new video was created using topographic data from the space agency's Lunar Reconnaissance Orbiter (LRO), which has been circling the moon since 2009. "This new simulation allows anyone to virtually ride with the astronauts and experience the awe they felt at the vista in front of them," NASA said in a release teasing the video. It was Christmas Eve 1968, and the first lunar voyagers in all of history â Apollo 8 astronauts Frank Borman, James Lovell and William Andersâ were emerging from behind the moon for the fourth time. What followed was an impromptu photo opportunity, first in black and white (building on the first "Earthrise" captured by NASA's Lunar Orbiterprobe two years earlier) and then after quickly locating the proper film cartridge, in stunning full color.
