“[Carl] Sagan was a member of the Voyager Imaging Team. He had the original idea in 1981 to use the cameras on one of the two Voyager spacecraft to image Earth. He realized that because the spacecraft were so far away the images might not show much. This was precisely why Sagan and other members of the Voyager team felt the images were needed — they wanted humanity to see Earth’s vulnerability and that our home world is just a tiny, fragile speck in the cosmic ocean.” Nasa.gov: Voyager 1’s Pale Blue Dot
