Ranger 7 B-camera image of Guericke crater (11.5 S, 14.1 W, diameter 63 km) taken from a distance of 1335 km. The dark flat floor of Mare Nubium dominates most of the image, which was taken 8.5 minutes before Ranger 7 impacted the Moon on 31 July 1964. The frame is about 230 km across and north is at 12:30. The impact site is off the frame to the left. (Ranger 7, B100)

The Ranger series of spacecraft were designed solely to take high-quality pictures of the Moon and transmit them back to Earth in real time. The images were to be used for scientific study, as well as selecting landing sites for the Apollo Moon missions. Ranger 7 was the first of the Ranger series to be entirely successful. It transmitted 4,308high-quality images over the last 17 minutes of flight, the final image having a resolution of 0.5 meter/pixel.

Ranger 7 was launched July 28, 1964 and arrived at the Moon on July 31, 1964.
