VIKING I EXPEDITION ANNIVERSARY

This is the first coilor photograph ever taken on Mars, snapped July 21, 1976. The rocky wasteland, colored by iron oxide, at last provided an image to match the nickname "red planet." Viking I touched down on the surface of Mars 30 years ago on July 20, 1976. (UPI Photo/NASA)
