Cassini’s been in orbit around Saturn since 2004, and it’s never coming home. Late last month, NASA organized the “Wave at Saturn” event in which it asked folks to submit photos of themselves waving at the spacecraft. The images came from 1,400 folks across 30 states and 40 countries. With an image of earth as the base, NASA turned the submitted images into a mosaic, and it’s a stunning example of space’s power to bring people together. You can check out the full size image here.
