'Levitating' Moon Dust Explained in New NASA Study >

What's more, this electrostatic dust mobilization may help explain the formation of "dust ponds" on asteroid Eros and Comet 67P/Churyumov-Gerasimenko, as well as the smooth surface on Saturn's icy moon Atlas"

""This new 'patched charge model' resolved a fundamental mechanism of dust charging and transport, which has been puzzling scientists for decades," Xu Wang"


NASA study finds solar storms could spark soils at moon's poles >
"Powerful solar storms can charge up the soil in frigid, permanently shadowed regions near the lunar poles, and may possibly produce "sparks" that could vaporize and melt the soil, perhaps as much as meteoroid impacts"

"on the moon, these particles—ions and electrons—slam directly into the surface. They accumulate in two layers beneath the surface; the bulky ions can't penetrate deeply because they are more likely to hit atoms in the regolith, so they form a layer closer to the surface while the tiny electrons slip through and form a deeper layer. The ions have positive charge while the electrons carry negative charge"

"In August 2014, however, Jordan's team published simulation results predicting that strong solar storms would cause the regolith in the moon's permanently shadowed regions (PSRs) to accumulate charge in these two layers until explosively released, like a miniature lightning strike."
-comment: ie an electric discharge

"Laboratory on experiments to see how breakdown affects the regolith and to look for any tell-tale signatures that could distinguish it from the effects of meteoroid impacts."
-comment, the rules for distinguishing are already well established (thunderbolts video, very good that NASA is studying this.

Very interesting developments, NASA is not shying away from electrical interpretations.

If the moon is being charged, all other celestial bodies without an atmosphere could be (are) charged the same way, interaction with the solar wind.

Interesting note: the second article has a picture of the moon with permanently shadowed regions in blue, they follow the craters....of course you might say...but what comes first... the shadow or the electrical interaction...

It seems like NASA would love to claim credit for discovering this.

Since many other people discovered this first, and published peer-reviewed articles detailing this behavior - how do the EU scientists go about claiming formal credit for such discoveries?

(Do we actually know who first discovered electric dust transport?)

The first person who used a feather duster?

I've not seen anything indicating that “EU scientists go about claiming formal credit for such discoveries”. They don’t. The situation is more so that the vast amount of existing established literature has long ago assessed electrostatic dust transport on airless celestial bodies. Such as:

Horizon Glow and the Motion of Lunar Dust

Effects of Levitated Dust on Astronomical Observations from the Lunar Surface

Electrostatic Charging of Lunar Dust

Dynamic Fountain Model For Lunar Dust

Electrostatic Effects on the Lunar surface

Etc; etc. With that in mind its unusual that a probe called LANDEE was needed in order to (yet again) make the assessment that "We expect dust particles to mobilize and transport electrostatically over the entire lunar surface, as well as the surface of any other airless planetary body" when the fact of the matter is that the overall assessment (with explanations) has been languishing in the archives for literally decades. This actually affords *anyone*, EU or otherwise, to have made the same statement of expectation before need of a probe – and they would've been correct.

What is interesting is the contrast between the very public face of astrophysics (news articles) and the physics lurking behind the scenes. For example, the following article on Comet 67P has quite a dull sheen to it insofar as descriptions and probable causes: COMET SINKHOLES GENERATE JETS. The difference between that article and the references below is remarkable.

Because: on the other side of the coin, a bit of research into the various instruments on any given probe and the papers concerning the findings brings in info like this:

Needless to say that those are merely the tip of the proverbial iceberg. I’m a bit confused as to why this probe was even necessary.
"Our laws of force tend to be applied in the Newtonian sense in that for every action there is an equal reaction, and yet, in the real world, where many-body gravitational effects or electrodynamic actions prevail, we do not have every action paired with an equal reaction." — Harold Aspden
