One of Earth’s most iconic images, 50 years on

The moment harkened back to another Christmas Eve, four years earlier, when the Apollo 8 astronauts — Frank Borman, Jim Lovell and William Anders — became the first humans to orbit the moon and witness “Earthrise” as our planet rose above the desolate, scarred lunar surface.

“We came all this way to explore the moon, and the most important thing is that we discovered the Earth,” Anders famously said.

The first photos taken of Earth by humans during the Apollo missions have become some of the most reproduced of all time, and 50 years later, their power and influence remain.

Still, the “Blue Marble” didn’t resonate immediately.
