À propos de cet audio

This episode reveals a groundbreaking scientific announcement: electric discharges occur on Mars. Long theorized, this phenomenon was accidentally confirmed by the Perseverance rover's SuperCam microphone. Researchers captured both electromagnetic and acoustic signals as the rover passed through two dust devils. The discharges are static electricity, created by intense friction between charged dust particles in the thin, carbon dioxide-rich atmosphere.

This historic discovery is critical for understanding Mars. The electrical events accelerate the formation of powerful oxidizing agents, which may solve the mystery of why Martian methane disappears so quickly. Furthermore, these high electrical charges influence dust movement, impacting climate dynamics, and they pose a potential hazard, capable of damaging sensitive electronics on both robotic and future human missions.
