Cassini spacecraft catches the Day the Earth Smiled Jul 22nd 2013, 15:00 High above the planet Saturn on Friday, Cassini took photographs of the backlit planet's rings and a twinkling Earth. If you looked at the skies, chances are you were photographed from space from NASA's Cassini spacecraft, almost a billion miles away. You're not the only one. For the first time in the nine years the spacecraft had been in orbit, Earth's inhabitants knew that their photos would be taken and came out to take part in "The Day that the Earth Smiled." Scientists knew this and a social media campaign had been waged in the weeks prior, urging Earthlings to participate in the worldwide event. Carolyn Porco, the leader of Cassini's Imaging Team and the founder of "The Day that the Earth Smiled," tweeted after the unique interplanetary photo-op, gushing. Back on Earth, photos were shared via a NASA Flickr gallery and Tweets hashtagged #DayEarthSmiled and #WaveatSaturn. Cassini began to beam down raw images on Saturday and fans began to produce unofficial color pictures. Guillermo Abramson, a physicist at Argentina's Bariloche Atomic Center, posted his attempts on his Facebook page. He then explained that the pictures are produced with both wide angle and telephoto lens. Each image has different filters, so they must all be combined to get cohesive colors. In addition, the spacecraft was moving between shots, so the images must be aligned. Val Klavans, an image processor and social-media leader for a film project, "In Saturn's Rings," uploaded her version of the finished product on Flickr. A mixture of Earth images are set to be used in a mosaic of Friday's cosmic event. Astronomers Without Borders are gathering photos of Saturn in an attempt to see the planet "as ordinary people do." An interactive image of Saturn's rings will be created, but "when you zoom in you'll see all the pictures from Earth that the mosaic is made of," the organization's website explained. According to the Cassini team website, Porco said that the first official images will be processed and released within the next few days and a mosaic – showing Saturn, its rings and Earth – will be completed in six weeks. "I can't wait to see the entire mosaic," Klavans tweeted, excitedly.
