flag Perseverance rover detected 55 mini lightning events on Mars, likely from dust storm static, in first direct evidence of electrical activity on the planet.

flag NASA’s Perseverance rover has detected 55 brief electrical discharges, or "mini lightning," on Mars, likely caused by static buildup from dust particles swirling in dust devils and storms. flag The signals, captured by the rover’s microphone over two Martian years, were accompanied by shockwaves and resemble static sparks, confirming long-held theories about electrical activity in Mars’ dusty, thin atmosphere. flag Though invisible in daylight, the discharges could pose risks to future robotic and human missions, potentially contributing to past failures like the Soviet Mars 3 lander. flag The findings, published in Nature, represent the first in-situ evidence of such activity, though some scientists caution that confirmation awaits dedicated instruments.
