Not quite all the craters on the Moon are natural features. About
28, and possibly as many as 36, according to Ewen A. Whitaker of the Lunar
and Planetary Laboratory, University of Arizona, have been caused by man.
Only about five of these artificial craters have been visually identified.
One of them (centered in the small rectangle) is shown in this enlarged
portion of a panoramic camera frame (about 6 km wide) in western Mare Cognitum.
The more than 2400 craters visible in this small area are typical of the
density of craters in many areas of the Moon. First located by Whitaker
(1972), the manmade crater is easily identified by its pattern of dark
rays interspersed with a few light rays. It was created in February 1971
by the SIVB stage of the Apollo 14 launch vehicle, which was directed to
crash onto the lunar surface to generate seismic waves for detection by
seismometers set up at the Apollo landing sites. The surface trace of the
SIVB's trajectory is shown by a dashed line. - H.J.M.
The same crater of figure 120 is shown in more detail in this photograph,
an enlargement of the area indicated by the rectangle in figure 120. About
40 meters in diameter, the crater differs from most natural impact craters
in this size range by having a prominent central peak. - H.J.M.
