According to a recent paper, scientists are now exploring whether so-called "electrical sparking may occur on the moon, altering the lunar soil.

The scientists have developed computer models to explore how strong electric fields might accumulate in permanently shadowed regions on the moon, creating electrical sparking that fragments soil grains.

Wal Thornhill offers a brief overview of the evidence of vastly greater, high-scale electrical discharge events that shaped the lunar surface."
