Solar storms may have torn away Mars water: NASA
www.chinaview.cn 2004-07-09 12:22:28

    BEIJING, July 9 (Xinhuanet) --  NASA scientists say solar storms might have torn away the water that used to cover parts of Mars. 

  ĦĦThey monitored the after-effects of a monster solar storm that hit Earth in last October and November. CRIENGLISH.com reported Friday.

    They think repeated battering by this kind of space weather could have ripped away Mars' water veil.

    According to observations by the Mars rovers Spirit and Opportunity, astronomers believe Mars once had enough surface water to support life, but they have not determined where that water went some 3.5 billion years ago.

    Scientists think the solar radiation events could have affected the surface of Mars because the planet has so little protection.

    Unlike Earth, only isolated zones of Mars has a protective magnetosphere that guards the planet against bombardment by high-energy particles during a solar storm.
