On November 19, 1969, the Apollo 12 lunar module Intrepid appears to float over the lunar limb, as photographed by Dick Gordon from inside the command module Yankee Clipper. The large crater occupying most of the lower half of this image is Ptolemaeus (with the smaller crater Ammonius within it); second largest is Herschel, at the right-hand edge of the photograph. At this time the lunar module (LM) was 69 miles (110 km) above the Moon’s surface.
