NASA rover spies the first aurora at Mars that’s visible to the human eye
- NASA's Perseverance rover captured the first visible aurora from the surface of Mars on March 18, 2024, in Jezero Crater.
- The event occurred after scientists anticipated a coronal mass ejection from the sun striking Mars' patchy magnetic field and atmosphere.
- The aurora appeared as a faint green glow caused by excited oxygen molecules, despite Mars’ thin atmosphere and lack of a global magnetic field.
- Roger Wiens explained that astronauts might see a faint greenish light from the aurora, and scientists mentioned that having three days' warning enabled them to prepare targeted camera observations.
- This discovery proves visible auroras occur on Mars, enabling future astronauts to potentially witness them and allowing scientists to forecast and study Martian space weather.

NASA’s Perseverance Snaps Rare, Eerie View of Mars’ Tiny Moon Before Sunrise
Perseverance caught a hauntingly beautiful glimpse of Mars’ tiny moon Deimos rising in the pre-dawn sky, using a long-exposure shot stitched from 16 images. At 4:27 a.m. local time on March 1, 2025, NASA’s Perseverance rover captured a striking view of Deimos, the smaller of Mars’ two moons, glowing faintly in the pre-dawn sky. It [...]
Astronauts Could See Auroras on Mars with their Eyes
Earth's magnetosphere channels particles from solar storms into stunning auroras. Mars lacks a planet-wide magnetic field and has patchy auroras barely detectable with instruments. Or so we thought. New images captured by NASA's Perseverance Rover with its Mastcam-Z instrument show green auroras in visible light. When humans finally walk on Mars and look to the skies, they could possibly see faint auroras there, too.
