"Blue Marble" The First Photograph of Earth..

On this date in history, Dec. 7, 1972, the Apollo 17 crew snap this iconic "blue marble" photograph of the Earth. This is the original caption: View of the Earth as seen by the Apollo 17 crew traveling toward the moon. This translunar coast photograph extends from the Mediterranean Sea area to the Antarctica south polar ice cap. This is the first time the Apollo trajectory made it possible to photograph the south polar ice cap. Note the heavy cloud cover in the Southern Hemisphere. Almost the entire coastline of Africa is clearly visible. The Arabian Peninsula can be seen at the northeastern edge of Africa. The large island off the coast of Africa is the Malagasy Republic. The Asian mainland is on the horizon toward the northeast.

The mission was the final in a series of three J-type missions planned for the Apollo Program. These J-type missions can be distinguished from previous G- and H-series missions by extended hardware capability, larger scientific payload capacity and by the use of the battery-powered Lunar Roving Vehicle, or LRV.
