Mars Dust Devils May Spark Lightning, Might Pose Risks to Rovers: Study
A new computer-modeling study reveals that dust devils on Mars—swirling columns of dust and air—may become electrically charged enough to spark lightning-like discharges. Led by researcher Varun Sheel, the study simulates how dry Martian conditions and frictional collisions between dust grains can generate strong electric fields inside these vortices. These charge...
