The Blue Marble is a famous photograph of Earth, taken by the crew of Apollo 17 on December 7th 1972, as they traveled to the moon. On January 23th, 2012, the Suomi NPP satellite snapped a similar, high definition photo, called Blue Marble 2012. By sure to check out the other side of the Marble, how the photos were taken and a PDF that describes the NPP project.
