A camera built by Hughes Aircraft will probably be the first to explore the moon's surface, and cameras are also reaching far back into the past. A nine-lens aerial spy produced by Itek will soon begin searching out ancient Mayan and Incan ruins in the jungles of Mexico and Guatemala. It will also be used to study the behavior patterns of a timid tribe of Mexican Indians—believed to be direct descendants of the Mayans—by spying on them from 20,000 ft. up.
