Summary:
Though Mars lacks a global protective magnetic shield like that of the Earth, strong localized magnetic fields embedded in the crust appear to be a significant barrier to erosion of the atmosphere by the solar wind. This conclusion by a researcher at the University of California, Berkeley, emerges from a new map of the limits of the planet's ionosphere obtained by the Mars Global Surveyor spacecraft.
