The fully processed composite photograph of Saturn taken by Cassini on July 19, 2013Earth can be seen as a blue dot underneath the rings of Saturn.The photomosaic from NASA's "Wave at Saturn" campaign. The collage includes some 1,600 photos taken by members of the public on The Day the Earth Smiled.
The Day the Earth Smiled is a composite photograph taken by the NASA spacecraft Cassini on July 19, 2013. During an eclipse of the Sun, the spacecraft turned to image Saturn and most of its visible ring system, as well as Earth and the Moon as distant pale dots. The spacecraft had twice taken similar photographs (in 2006 and 2012) in its previous nine years in orbit around the planet. The name also refers to the activities associated with the event, as well as to the photographic mosaic created from it.[1]
Conceived by the planetary scientist Carolyn Porco, the imaging team leader for Cassini, the concept called for the people of the world to reflect on their place in the universe, to marvel at life on Earth, and, at the time the pictures were taken, to look up and smile in celebration.[2][3]
The final mosaic captured on July 19, processed at the Cassini Imaging Central Laboratory for Operations (CICLOPS), was released to the public on November 12, 2013.[4][5] The photograph includes Earth, Mars, Venus, and many Saturnian moons.[6] A higher-resolution image, depicting Earth and the Moon as distinct points of light, was taken with Cassini's narrow-angle camera and was released shortly afterwards.
