It’s difficult to determine the exact moment when history takes a turning point. But when it comes to really seeing the beauty, fragility, and loneliness of our world, there’s a specific moment we know of. On December 24, 1968, the Apollo 8 spacecraft, manned by Frank Borman, Jim Lovell, and Bill Anders, entered the lunar orbit. When they were on the fourth orbit and coming out from the far side of the moon, they saw a view of the planet and it was stunning. Lovell quickly found a color canister to capture the first full-color view of our planet from space. This photo not only started the environmental movement, but also made people realize how lucky we are in a big, uncaring universe and how easily it can all disappear. A constant reminder of how delicate and small our lives are.
