The “Blue Marble” is a historical photograph taken on December 7, 1972, by the crew of Apollo 17 – Eugene Cernan, Ronald Evans and Jack Schmitt -, and is the first clear image of an illuminated face of Earth.
The photograph’s official designation is AS17-148-22727.
Apollo 17 was the last crewed lunar mission. No humans since have been at a range where taking a whole-Earth photograph such as the “Blue Marble” would be possible.
NASA archivist Mike Gentry has speculated that The Blue Marble is the most widely distributed image in human history.
