Look Back with SkySafari as Saturn Probe Images Earth

App sale for iOS, Mac, Android tracks Cassini event on July 19th

San Francisco, CA, July 16th, 2013 - On Friday, July 19th, 2013, the Cassini spacecraft - now in its 8th year orbiting the ringed planet - will image the Earth from the far side of Saturn. As the Earth prepares for its first interplanetary photo shoot, Southern Stars has released brand new updates to its SkySafari apps for iOS, Android, and Mac OS X, to let viewers all around the world follow the occasion.

This will be the first time that the Earth's inhabitants will know in advance that their picture is being taken from a billion miles away. Carolyn Porco, leader of the Cassini imaging team, originated the idea and led the effort to get the picture taken with her cameras on Cassini. Ms. Porco writes, "It is a rare opportunity for people the world over to stop what they're doing, go outside at the moment the picture is being taken, and celebrate their own existence on our beautiful, lush, life-giving planet."

SkySafari's basic version will be free on the iTunes Store from July 19th through July 21st; it's normally USD $3 on the iTunes Store and Google Play. With SkySafari, observers around the globe can easily use their iPhone or Android's GPS, compass, and accelerometer to easily locate Saturn in the sky. A brand new release of SkySafari Plus and Pro (3.8.1) lets mobile app users fly to Saturn, and simulate the view from Cassini. These powerful apps will be offered at up to 25% off regular price on July 19th, the day of the event, through Sunday July 21st.

Because the public outreach surrounding The Day The Earth Smiled has global scope, Southern Stars will donate 15% of all app proceeds on July 19th to Astronomers Without Borders. AWB is coordinating grassroots outreach programs around the world in association with the event. All three version of SkySafari for iOS have recently been internationalized to Spanish and French, as well as English, making them an even better choice for Saturn-watchers worldwide.

Southern Stars has created a short video which shows how to view Saturn, and simulate the Cassini event on July 19th, with SkySafari Plus on an iPad. The event is shown both from California, USA, and from Cassini itself, looking back on Earth from Saturn.
