Earth's Moon - Ranger 9

Final two images taken by Ranger 9 before impact

Earth's Moon
This image shows the last two pictures taken by Ranger 9 before impact onto the lunar surface. The images show the floor of Alphonsus crater at 12.84 S, 2.39 W. North is at 1:00 in both images. The top image was taken by camera P3 at a distance of 600 m just 0.25 seconds before impact. The frame is about 70 m across. The lower frame is from camera P1. It includes most of the area on the left of the P3 frame and was taken from 1.2 km 4.5 seconds prior to impact. The image is approximately 50 meters across. Part of the P3 frame is missing because Ranger 9 did not finish transmitting before impact. These were the last images from the Ranger program, which ended with this mission. (Ranger 9, P012)
