August 23, 2013 – On July 19 the Cassini orbiter photographed Earth from Saturn at 5:27 p.m. EST. NASA not only asked people to look up to the sky and wave at that time–they also asked the people of the world send them pictures of themselves waving to Saturn for a reason that was unknown until Wednesday.
On Wednesday NASA released a mosaic of Earth made up of 1,400 photos they received from over 40 countries! NASA published the mosaic to their Facebook page with the caption "Did you wave at Saturn and send us your photo? Then here's looking at you!"
Linda Spilker, Cassini project scientist for NASA, said "Thanks to all of you, near and far, old and young, who joined the Cassini mission in marking the first time inhabitants of Earth had advance notice that our picture was being taken from interplanetary distances."
"While Earth is too small in the images Cassini [took] to distinguish any individual human beings, the mission has put together this collage so that we can celebrate all your waving hands, uplifted paws, smiling faces, and artwork."
