CAPE CANAVERAL, Fla. -- Scientists have detected what they believe to be lightning on Mars by eavesdropping on the whirling wind recorded by NASA's Perseverance rover.

The crackling of electrical discharges was captured by a microphone on the rover, a French-led team reported Wednesday.

The researchers documented 55 instances of what they call "mini lightning" over two Martian years, primarily during dust storms and dust devils. Almost all occurred on the windiest Martian sols, or days.

Just inches in size, the electrical arcs occurred within 6 feet of the microphone perched atop the rover's tall mast, part of a system for examining Martian rocks via camera and lasers. Sparks from the electrical discharges -- akin to static electricity here on Earth -- are clearly audible amid the noisy
