LEWISTON, ME – AUGUST 22: This Planet Earth Balloon, piloted and owned by Doug Grimes, is made of 436 panels made from digital photographs taken of the earth by astronauts in the Apollo 17 and Space Shuttle. Taking over nine months to print the panels, that were then stitched together, it is the only digitally printed ballon in existence, according to Grimes. It stayed tethered to the ground at the Great Falls Balloon Festival in Simard-Payne Park in Lewiston. (Photo by Gordon Chibroski/Staff Photographer)
