IFL ScienceFirst-Ever Evidence Of Lightning On Mars – Captured In Whirling Dust Devils And Storms
Overview
NASA's Perseverance rover has serendipitously detected "mini lightning" on Mars, capturing acoustic and electromagnetic signals of electrical discharges in the planet's dusty atmosphere, marking a significant discovery.
Over two Martian years, researchers analyzed 28 hours of Perseverance's SuperCam recordings, identifying 55 instances of these electrical discharges, primarily occurring during dust storms and dust devils.
This confirmation by a French-led team makes Mars the fourth known world with lightning, joining Earth, Jupiter, and Saturn, providing new insights into planetary atmospheric phenomena.
The electrical discharges, akin to static electricity, are audible amidst wind and dust, with dust devils producing brief zaps and dust storms generating longer-lasting discharges up to 30 minutes.
This direct evidence, previously elusive despite theories, supports the existence of lightning on Mars and aids the rover's mission to examine Martian rocks and search for ancient life.
