说明NASA - NATIONAL AERONAUTICS AND SPACE ADMINISTRATION 400 MARYLAND AVENUE SW, WASHINGTON, D.C. 20546 FOR RELEASE: Immediately PHOTO NO.: 64-Ranger B-23 THIS PHOTOGRAPH IS USED FOR ADVERTISING PURPOSES COPY AND LAYOUT MUST BE SUBMITTED TO NASA FOR APPROVAL PRIOR TO RELEASE. Photograph taken by the Ranger VII spacecraft prior to its impact on the moon at 6:25 A.M. PDT July 31. Viewed with the partial picture and line of receiver noise at the top, North is at the top of booth pictures. The top partial picture was the last taken by the P-3 camera with a 25mm. lens f-1, before Ranger VII crashed onto the Moon. The spacecraft was destroyed while transmitting, resulting in the receiver noise pattern. The picture was taken 1,000 feet above the lunar surface and is an area of about 100-feet by 60-feet. It has a resolution one-thousand times better than seen by Earth-based observatories. The smallest craters are about three-feet in diameter and one-foot in depth. The lower complete picture, showing an area about 100-feet on a side, was taken by the P-1 partial scan camera with a 75mm, f/2 lens at an altitude of about 3,000 feet. Many of the craters shown have rounded shoulders in contrast with most large lunar craters. Ranger VII is a program of the National Aeronautics and Space Administration and its Jet Propulsion Laboratory.
