The Loneliest Photograph
As part of the three-man crew that made up NASA's 1969 Apollo 11 mission, Command Module Pilot Michael Collins may not be remembered in the annals of space flight to the extent of his fellow mission members Buzz Aldrin and Neil Armstrong; the televised mission famously broadcast the first humans to ever step foot on the moon, and Michael Collins was not one of them.
Collins does have a unique claim to fame, though. While Armstrong and Aldrin roamed the lunar surface, Collins spent over 21 hours alone in the Command Module, with Mission Control famously stating "Not since Adam has any human known such solitude." And more, Collins created something astoundingly unique: the above photograph. When he captured this image, Collins was the only human being, living or dead, not contained within the frame of this picture.
