An undated artist's rendering depicts a solar storm hitting Mars and stripping ions from the planet's upper atmosphere in this NASA handout released November 5, 2015. Scientists have documented a solar storm blasting away Mars’ atmosphere, an important clue in a long-standing mystery of how a planet that was once like Earth turned into a cold, dry desert, research published on Thursday shows. On March 8, NASA’s Mars-orbiting MAVEN spacecraft caught such a storm stripping away the planet’s atmosphere, according to a report published in this week’s issue of the journal Science.
