Mercury's magnetosphere fends off the solar wind

The planet Mercury's magnetic field appears to be strong enough to fend off the harsh solar wind from most of its surface, according to data gathered in part by a University of Michigan instrument onboard NASA's Messenger spacecraft.

   When NASA's MESSENGER spacecraft makes its historic flyby of Mercury on Monday, Jan. 14, 2008, Brown University students, led by planetary geologist James Head, will be part of the action. At mission headquarters and at Brown, these planetary experts will help analyze images from Mercury, the smallest planet in the solar system. Head leads the MESSENGER mission's geology group, overseeing analysis of Mercury's volcanic features and dating rocks on the planet's cratered surface.

10. 3.2 billion-year-old surprise: Earth had strong magnetic field
    04-04-2007 · EurekAlert!
    Geophysicists at the University of Rochester announce in today's issue of Nature that the Earth's magnetic field was nearly as strong 3.2 billion years ago as it is today.The findings, which are contrary to previous studies, suggest that even in its earliest stages the Earth was already well protected from the solar wind, which can strip away a planet’s atmosphere and bathe its surface in lethal radiation.
