EDM crater eld. A eld of six craters of varying size, some sharing rims. It would be suspected these elds occur as a result of changing potentials at the surface, the discharge consequently taking the path of least resistance and forming several craters in the process.

We consider an alternative hypothesis of crater formation -- through an electric discharge machining (EDM) of the celestial bodies' surfaces. The source of the energy and the current itself may lie in the plasma infalling on a celestial body (from an extremely strong solar outburst or a nearby supernova). This mechanism may have been even more impo...

... bear striking similarity to large scale surface features on planets and their satellites. Small formations are typically bowl shaped with raised rims ( 5). These formations will occur if the discharge duration is short or a conductive path is formed as mentioned in section 3.1. It is also possible for several small craters to form a field (Fig. 6). These fields can look analogous to fields of simple "secondary" craters. Smaller fields can produce craters side by side separated by distinct walls (Fig. ...
