NASA's early lunar images, in a new light
Pictures from the mid-1960s Lunar Orbiter program lay forgotten for decades. But one woman was determined to see them restored.
Altogether, nearly 2,000 frames were photographed by the five missions, each of which ended with a silent crash onto the lunar surface.
Although the original high-resolution images were saved on 2-inch-wide tape, those pictures weren't seen by the public.
