“…Observations of the plasmapause utilizing the rapid increase in sheath effects occurring when a satellite carrying a small electric field probe crosses the plasmapause and enters regions of low plasma density [Cauffman and Maynard, 1974;Maynard and Chen, 1975;Maynard and Grebowsky, 1976 Finally, one problem somewhat related to the direct probing of E is the charging of spacecraft to high potentials, caused by particle beams in the magnetosphere. This phenomenon is still under study [DeForest, 1972[DeForest, , 1973[DeForest, , 1976Fredricks and Scarj} 1973;Cauffman, 1973b], but it appears that potentials reaching several thousand volts can be developed.…”

Studies of the earth's magnetosphere have indicated that a large-scale electric field E plays a central role in its electrodynamics and in the flow and acceleration of charged particles there: while many observations relevant to E have accumulated, quite a few basic problems involving the origin and structure of this field remain unsolved. The ultimate source of E is presumably the flow of the solar wind past the earth, but the mechanism by which E arises is still unclear, and several independent sources may contribute to it, some of them (e.g., substorm fields and E•) being of a rather transient nature. This review attempts to sum up the main observed facts and theoretical concepts related to E. It also contains brief sections on experimental methods and on Birkeland currents, and it concludes with a list of basic questions related to the magnetospheric electric field to which satisfactory answers have yet to be found.

Electrostatic charging and dust transport at Mercury's surface

A consideration of the presence of energetic charged particles in the magnetosphere of Mercury and their direct interaction with the planetary surface leads to the tentative conclusion that the nightside hemisphere could be occasionally charged to a surface potential of a few kilo‐Volts. This electrostatic charging process, if feasible, would further imply that electrostatic transport of sub‐micron dust particles on the surface of Mercury could play a significant role in the evolution and modification of the surface dust layer. Electromagnetic perturbation on the motion of the charged sub‐micron ejecta from meteoroid impacts could also lead to the development of a tenuous dust coma or dust tail near Mercury.
