The Day the Earth Smiled refers to July 19, 2013, the date on which the Cassini spacecraft turned to image Saturn, most of its visible ring system, and Earth, during an eclipse of the Sun. The spacecraft had done this twice before (in 2006 and 2012) in its previous nine years in orbit. The name is also used to refer to the activities associated with the event, as well as to the photographic mosaic created from it.
