In the 1960's the Ranger Moon shots sent the first
televised closeup images of the Moon before crashing into its surface.
Astronomers noted many odd features of crater distribution that were
difficult to explain by random impacts.
Lunar craters tend to occur in pairs
and lines. Some lines of craters were attributed to cracking and
subsidence of the surface. Others were thought to be due to impacts. The
difficulties in choosing a cause for the heavy cratering of the Moon was
finally settled by a vote. But were all of the candidate mechanisms
Craters formed by electric discharge exhibit
circular symmetry with little disturbance to pre-existing craters.
Electrical craters can appear to be distributed randomly, but they are
not. They naturally form clusters, lines, and arcs. The size of craters
within linear groupings are often graduated. Small craters are found cut
into the rims of large craters, but the reverse is seldom seen.
The above pictures illustrate a common pattern of
electrically excavated craters. In the laboratory (inset image) a large
crater is being carved. Where the rim of the main crater is lifted above
both the original surface of the clay and the crater bottom, the arc
jumps to high points on the rim. This produces smaller secondary craters
centered on the rim of the original crater. You can see craters on the
rims on many of the craters in the main image, taken by Mariner 10 as it
flew past the planet Mercury. It is not a pattern expected of impacts.
