NASA's Perseverance rover detects lightning-like discharges on Mars for the first time

Scientists have confirmed the first detection of lightning-like electrical discharges on Mars. The discovery was made by NASA’s Perseverance rover, which recorded 55 such events near its location. This electrical activity had long been suspected but never directly proven until now. In 2006, unusual signals from Mars hinted at possible lightning, but doubts remained. Now, the rover’s data provides clear evidence. Friction in swirling dust creates electrical charges, leading to these discharges.

Out of the 55 events, 54 took place during strong winds. Dust devils were involved in 16 of them. Each event was preceded by an electrical disturbance affecting the rover’s microphone system. These discharges may alter the chemistry of Mars’ atmosphere and surface. They could produce highly reactive substances like hydrogen peroxide. As a cytotoxin, this compound might reduce the chances of finding microbial life on the planet.
