NASA’s MAVEN Witnessed Auroras as Multiple Solar Storms Crashed into Mars - by ET_Exists
, and both types were able to be observed primarily thanks to Mars being near the end of its annual dust storm season, which happens whenever the Red Planet orbits closest to the Sun.
“I was so surprised to see proton aurora at the same time as diffuse aurora, because it had never happened before,” said Dr. Sumedha Gupta, who is a postdoctoral researcher at the University of Colorado Boulder. “They’re both increasing with solar activity, so we hope it keeps happening!” While the auroras observed by MAVEN were comprised only of data and no imagery, this nonetheless demonstrates how Mars is still an active planet, despite being both cold and bone dry.that the Red Planet both once had one and the reasons why it might have disappeared, and part of the continued mission of MAVEN is to answer these longstanding questions.
