NASA's Perseverance rover has made a significant discovery by detecting electrical discharges on Mars, called 'mini-lightning', during the exploration of Jezero Crater. These discharges were captured by the SuperCam instrument, which recorded 55 electrical events in 28 hours of observation. The electrical activity in the planet's thin atmosphere has important implications for atmospheric chemistry, climate, and habitability of Mars, as well as for future missions.

Researchers explained that these discharges are caused by friction between dust particles, which accumulate electric charges and discharge in the form of small electric arcs. This electrical activity on Mars joins similar phenomena observed on Earth and other planets, but is more likely due to the thin carbon dioxide atmosphere. The discovery provides a new understanding of Martian atmospheric dynamics and the risks to electronic equipment and astronauts in future explorations.
