The Blue Marble
The Blue Marble is a photograph of the Earth. It was made on December 2, 1972, by the crew of the Apollo 17 spacecraft. At that time they were on their way to the Moon at a distance of about 29,020 kilometers (18,000 miles) from the Earth. It is one of the most reproduced images in human history.
The name, Blue Marble, has also been used by NASA for a 2012 series of photographs covering the entire globe at relatively high resolution. These photographs were created by carefully choosing pictures taken by satellites, and joining them together, to show the Earth without cloud cover.
