Earth's Moon - Ranger 8

Ptolemaeus and Alphonsus craters on the Moon

Earth's Moon
The first image taken by the Ranger 8 camera B on 20 February 1965 shows the 164 km diameter Ptolemaeus crater, top center, and below it Alphonsus crater (diameter 108 km). The Davy crater chain can be seen immediately to the right of the left-middle reticle mark as a dotted white line extending SWW to NEE. The picture was taken 23 minutes before impact from a range of 2545 km. The image is about 360 km across and north is up. Ranger 8 was the second successful lunar impact mission in the series.
