Lightning

A new study suggests lightning may be weak or nonexistent in Martian dust storms. Researchers vibrated basalt grains at various atmospheric pressures to test their ability to build up charge.

Lightning in a dust storm plays a role in my forthcoming book, Air: Generation Mars, Book One. Hard science fiction is a moving target. Still, the fictional strike in question is weak and only damaging to electrical equipment, so I think it’s plausible.

I can’t count the number of articles that have floated through my various feeds starting with the mocking phrase “Sorry Elon…” Google it yourself and see what I mean.
