Electric comet 67p

electric comet 67 p active asteroid RosettaCould the the negatively charged Rosetta comet 67p (active asteroid) be interacting with the Suns positive solar wind (plasma) and well as the Rosetta spacecraft itself?

Also, importantly, most of the fluffy particles were detected hitting GIADA at less than 1 m/s. Because the escape speed of both types of dust particles from the surface of Comet 67P/C-G should be the same, the fluffy aggregates must be decelerated somehow. The scientists believe that this is happening due to Rosetta itself.

Measurements made by Rosetta’s RPC-LAP instrument show that the spacecraft is negatively charged at between –5 and –10 volts due to a variety of effects associated with the plasma environment of the comet and with solar UV photons hitting the spacecraft. This negative potential acts to decelerate approaching dust particles, which are also negatively charged.

Would this explain the surprising activity on and around the comets plasmasphere/magnetosphere - including jets and molecules?

Electric potential difference, electrical stress, electrical discharge machining (EDM) etc.

The solar wind is made of Hydrogen (95%) and Helium (4%) and Carbon, Nitrogen, Oxygen, Neon, Magnesium, Silicon and Iron (~1%). These atoms are all in the form of positive ions which means they have lost electrons because the temperature is so hot. So really, solar wind is positive ions and the electrons these ions have lost. We call this plasma.
