The Only Photograph That Has Ever Made Everyone Quiet

On December 7, 1972, the crew of Apollo 17 were about 29,000 kilometres from Earth when one of them — probably Harrison Schmitt, though no one ever confirmed it with certainty — pointed a Hasselblad camera back toward home and pressed the shutter.
The photograph showed the whole Earth, fully illuminated, suspended against absolute black. It became known as the Blue Marble. It is possibly the most reproduced image in the history of photography.
What makes it unusual is what it does to people. There's a documented phenomenon called the Overview Effect — first named by writer Frank White in 1987 — describing the cognitive shift that astronauts report when they see Earth from space for the first time. The borders disappear. The conflicts seem small. The fragility of the atmosphere, a thin blue line at the horizon, becomes viscerally clear.
The Blue Marble arrived at a particular moment. The environmental movement was gaining ground. Earth Day had happened two years earlier. The image of a whole, finite, vulnerable planet gave the movement something it had been missing: a picture.
Apollo 17 was the last crewed mission to the Moon. No human being has been back since 1972, and no human being has taken another photograph like this one. Everything since has been composites, or images taken by unmanned probes. The Blue Marble is still the only photograph of the whole Earth taken by a human hand.
