blue marble (10. 368)

Photographed by one of the crew, likely Harrison Schmitt or Gene Cernan but ever member took turns taking pictures with the Hasselblad camera, of the Apollo XVII mission on its way to the Moon from a distance of just under thirty thousand kilometers on this day in 1972. Backlit and slightly rounded—gibbous and hence the name—from the astronauts’ perspective and after Earthrise only the second whole planet image captured by a human photographer, the Blue Marble is among the most widely reproduced and circulated images in existence, it was received by the public at a moment of increased environmental activism and awareness and helped focus the movement by framing Earth’s uniqueness and vulnerability set against the endless expanse of space. Although recreated by satellite imagining, there have been no crewed excursions since that taken us high enough aloft—yet—to fit the entire planet in the view-finder.
