Nasa has cracked the mystery over Mars missing atmosphere

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, Nasa scientists said on Thursday (5 November). On 8 March, Nasas Mars-orbiting Maven spacecraft caught such a storm stripping away the planets atmosphere, scientists said. Maven lead researcher Bruce Jakosky said the stripping of Mars atmosphere took place hundreds of millions of years ago and has slowed down since. Nov 6, 2015
