#On_this_day 52 years ago The Blue Marble is a photograph of Earth taken on December 7, 1972, from a distance of about 18,300 miles from the planet's surface. Taken by the crew of the Apollo 17 spacecraft on its way to the Moon, it is one of the most reproduced images in history. There were no digital cameras, no Photoshop programs, no internet at the time yet this went viral around the world.
