The first lunar images were taken more than 40 years ago by five Lunar Orbiter spacecraft that took more than 2,600 images that cover 99 percent of the lunar surface. These Lunar Orbiter images have been cataloged and digitally mastered by the Lunar and Planetary Institute (LPI) and are available on their website here.
The digitally scanned images from both the USGS and LPI are cataloged by individual orbiter and by coordinates. The images are accompanied by details such as spacecraft position, photograph position, and lunar surface illumination.
Because of the extensive coverage of these photographs, they are being used again in preparation for Project Constellation that is designed to renew U.S. exploration of the Moon.
