NASA rover hears electric crackles inside Mars dust devils
Pasadena CA (JPL) Dec 04, 2025
NASA’s Perseverance rover has directly detected tiny electrical sparks and associated shock waves inside Martian dust devils, confirming that the Red Planet’s ubiquitous whirlwinds can generate "mini-lightning" through charged dust. Using the SuperCam instrument’s microphone and electromagnetic sensors, the team identified brief crackles and pressure spikes that reveal triboelectric discharges o
