Happy 45th birthday, Blue Marble! The famous Blue Marble photo was taken by Apollo 17 astronauts on December 7, 1972.
It’s become one of the most widely distributed photographic images in existence.
Although often seen as a depiction of Earth’s frailty and isolation amid the vast expanse of space, it’s also a reminder that this amazing place is where we all live. Lucky us, really.
Apollo 17 was the last manned lunar mission. No human since has been far enough from Earth to photograph a whole-Earth image like The Blue Marble.
