I don't think any of the moons of Jupiter have enough atmosphere to have lightning. What about Titan, could lightning form there? By the way, why is this in Not so Free Chat? I think weather on Jupiter's Moons is not political, could legitimately appear elsewhere. Science, Technology, and Astronomy would be an appropriate place to put this.

lightning in the cracks of the ice . piezo electric effect . maybe ..earthquake reportedly have electrical discharges . inner liquid ocean at 1 in electrical potential . outer surface in vacuum . bombarded by sunlight radiation and magnetism . ice is in electrical insulator . but the cracks in the ice especially if they're contaminated with other substances might conduct electricity . observable path of lightning might be across the surface of the I might just be observable . sprites in the thin atmosphere unlikely . but I think its okay to look for them . we didn't know they occurred in the upper atmosphere of Earth until relatively recently . could in electrical discharge create a body of liquid water in a crack nearer to the surface than the ocean . What? Better manners would be welcome.

Your new writing... style... is hard to understand. Are you asking if the Jovian radiation belts could melt ice?

I'm not quite sure what is being discussed here, but it seems to be about possible electrical phenomena.
Spacecraft charging, leading to destructive discharges, is a very real problem.
I'd guess there's a different charging potential at each radius from the sun. We didn't get hit too bad going to the moon (same charging potential).
Makes you wonder if some of the failed Mars landers failed from electrical discharges internally. Air too thin to bleed off the charge during entry, but too thick to behave like vacuum either, at landing.

Yes Terraformer, I did make a mess of my posts. Tom, sure I don't mind if this is moved. GW yes that is also a concern.
However I was thinking about the fact that ice is generally an insulator, and that a subsurface ocean might have a different charge than a certain part of the surface, and that the different areas of the surface might have different charges one location to another.
Ionizing radiation could allow even a thin atmosphere to conduct. Also the surface itself could be a drainage path for a current flow. Further if there were a discharge of vapors and water to the surface, then a temporary path from the surface to the ocean could occur.
I also wonder about the cracks themselves being compressed and decompressed if piezo electric effects could occur. Clean ice might not have much of those effects, but likely the materials in the cracks are not clean ice, so it is unknown.
So, I was speculating on the idea that currents flowing through the cracks could create melt water pockets that would be more accessible than the subsurface oceans. The notion that perhaps habitats for life could periodically be liquid in the cracks, with Oxygen related compounds, and perhaps fuel materials being mixed in the ice of the cracks.
I am not fond of what I consider to be an agenda by some to use such a finding of life to alter the religious beliefs of the popular culture, but I am not against speculation on a remote possibility that such habitats could exist.
But yes in general even without the issue of life the electrical properties of moons would be something to have awareness of if possible for the sake of future expeditions to the environments.
Thanks for patience rendered. I won't use my phone anymore.
