Electric Phobos and Deimos

Sparky said: would "light bluish" regions probably be areas of continued electrical discharge.?

* Do you have any reasoning behind that question? Regarding Venus, Thornhill has suggested that shiny areas are where there is St. Elmo's fire, which is some sort of electric discharge. So I'd go with shiny areas first.

yes, i remember reading about "bright" areas that were speculated to be discharges. When i saw the bluish areas i thought that maybe these could be discharges also. Just trying to solidify my understanding of EU phenomenon and get feedback to consider.

Stickney Crater and the egg

What simple clues might we gleen from considering the similarities between the appearance
of Stickney crater and that of this image of an egg's interior, especially considering that we
still do not know how bodies in this solar system were formed?

Stickney's present appearance may be only the latest surface etching,, well seperated
from a formative period when a sub-crust feature was formed...

Considering the location of stickney crater, at the narrow end of an oblong body
which has grooves along the surface tracking parallel to it long dimension we might
wonderd what movement this body experienced before its surface solidified.

We might also wonder what an object looks like after it skims off an atmosphere
getting is surface superheated and and maybe etched,, but scarred for life. d...z

dahlenaz,

In your long work, have you run on a parallel for the parallel tear-drop shape "dunes" on Mars ?

Depositions, field-etching, ablated egg ??

What's wrong with a Coulomb crystal model? The sphere, oblate sphere, ovoid, peanut shaped regular ones, plus irregular ones which will most likely be found at the center of irregular shaped asteroids. You have the dusty plasma and the torus or curved flux tubes out there, and the methods for developing RF (at the small scale laboratory levels, probably much lower frequencies for the larger scale) modulation, and then growth by layered deposits through sputtering, plus the electric cratering. I'd say that the formations are produced very quickly too, when (IMO) the Sun goes into hyper-active mode.

Coulomb solidification is also of interest to researchers who study space dust, because the existence of Coulomb solids formed from the space dust could be possible, for example, in a planetary ring.

How this Martian moon became the 'Death Star'

For the first time, physicists at LLNL have demonstrated how an asteroid or comet impact could have created Stickney crater without destroying Phobos completely. The research, which also debunks a theory regarding the moon's mysterious grooved terrain, was published in Geophysical Review Letters.

Their supercomputer models, given enough time and tweaking of numerous variables, might eventually produce a model that could offer a possible mechanical explanation, but wouldn't it just be far easier and simpler to accept the electrical explanation? They can't of course, as that would cast all the accepted models of crater formation on all other bodies into absolute turmoil.

Could it be the 'mainstream' is getting on the EU bandwagon?

Solar eruptions could electrify Martian moons

Powerful solar eruptions could electrically charge areas of the Martian moon Phobos to hundreds of volts, presenting a complex electrical environment that could possibly affect sensitive electronics carried by future robotic explorers, according to a new NASA study.

The solar wind is responsible for these charging effects. When the solar wind strikes the day side of Phobos, the plasma is absorbed by the surface. This creates a void on the night side of Phobos that the plasma flow is obstructed from directly entering. However, the composition of the wind - made of two types of electrically charged particles, namely ions and electrons - affects the flow. The electrons are over a thousand times lighter than the ions. "The electrons act like fighter jets - they are able to turn quickly around an obstacle—and the ions are like big, heavy bombers - they change direction slowly," said Farrell. "This means the light electrons push in ahead of the heavy ions and the resulting electric field forces the ions into the plasma void behind Phobos, according to our models."
