NASA’s Perseverance Rover Captures First Visible-Light Aurora on Mars: A New Chapter in Planetary Atmospheric Studies

On March 18, 2024, NASA's Perseverance rover achieved a groundbreaking feat by capturing the first-ever visible-light aurora on Mars. This observation marks a significant milestone in planetary science, as it provides direct visual evidence of auroral activity from the Martian surface—a phenomenon previously detected only in ultraviolet wavelengths by orbiting spacecraft. The faint green glow observed was the result of a solar flare and subsequent coronal mass ejection (CME) from the Sun, which released energetic particles that interacted with the Martian atmosphere .
