Apollo Imagery
The silicon disk left on moon by Apollo 11

S69-39148 (July 1969) --- Close-up view of the one and one-half inch silicon disk which will be left on the moon by the Apollo 11 astronauts. The disk bears messages of goodwill from heads of state of many nations. The process used to make this wafer is the same as that used to manufacture integrated circuits for electronic equipment. It involves making tiny photographic images and depositing metal on the images. The Kennedy half-dollar illustrates the relative size of the memorial disk.
