A visible aurora has been recorded from the surface of Mars for the first time. NASA’s Perseverance rover detected a faint green glow of atomic oxygen triggered by a solar storm, confirming long-standing predictions about atmospheric emissions. The detection provides a new way to study Martian space weather from the surface.
When charged particles from a solar storm reached Mars this month, they set off an aurora 25 times brighter and surface level radiation readings twice as high as any previous measurements. An unexpectedly strong blast from the Sun hit Mars this month, observed by…
Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has observed two unexpected phenomena in the Martian atmosphere: an unexplained high-altitude dust cloud and aurora that reaches deep into the Martian atmosphere.The presence of the dust at orbital altitudes from
