Sun Could 'Sandblast' the Moon

Solar storms and ejections can significantly affect and erode the surface of the moon. "In addition to removing a surprisingly large amount of material from the lunar surface, this could be a major method of atmospheric loss for planets like Mars that are unprotected by a global magnetic field." Learn more about this research being led by Rosemary Killen at NASA's Goddard Space Flight Center, Greenbelt, Md, and watch her computer simulations here. I envy Rosemary Killen for studying Sun and Moon everyday and learning how they interact and affect each other.
