MAJOR SPACE WEATHER EVENT ON MARS: Last month, a human astronaut standing on the surface of Mars could have seen something amazing. The night sky of the Red Planet turned green in a global display of Northern Lights. Unfortunately, the same astronaut would have been irradiated by high energy particles from the sun. For three days in mid-September a solar storm enveloped Mars, crossing thresholds of ground-level radiation and auroras that orbiters and rovers had never seen before. Such global events on Mars may be more common than previously thought--a topic explored on today's edition of  Spaceweather.com.
