NASA's Cassini spacecraft, currently in orbit around Saturn, will be turned to image that planet and its ring system during an eclipse of the sun, as it has done twice before during its previous nine years in orbit. But this time, the images collected will capture a glimpse of our own planet alongside Saturn, in what will be the first time the Earth's inhabitants know in advance their picture is being taken from a billion miles away.

And now, even Morgan Freeman is getting ready for that splendid and brief moment of cosmic self-awareness and global celebration of us and our lush, life-giving planet coming this Friday. Join with him to celebrate The Day The Earth Smiled.
