Dust-Driven Lightning on Mars: NASA Data Hint at Electrical Sparks in Dust Storms

Two NASA missions—MAVEN in orbit and the Perseverance rover on the surface—have detected signals suggesting lightning or related electrical discharges in Mars' dusty atmosphere. MAVEN identified a rare whistler radio signal from a 2015 data set, while Perseverance recorded crackling sounds during dust storms likely from electrostatic discharges in charged dust clouds. Taken together, the findings strengthen the case that Mars experiences dust-driven electrical activity, with possible implications for atmospheric chemistry and the planet's environment, though large lightning bolts remain unlikely.
