NASA’s Solar Shield to mitigate damage to power grid from severe solar storms

The solar storms that cause the stunning aurora borealis and aurora australis (or northern and southern polar lights) also have the potential to knock out telecommunications equipment and navigational systems and cause blackouts of electrical grids. With the frequency of the sun’s flares following an 11-year cycle of solar activity and the next solar maximum expected around 2013, scientists are bracing for an overdue, once-in-100 year event that could cause widespread power blackouts and cripple electricity grids around the world. It sounds like an insurmountable problem but a new NASA project called “Solar Shield” is working to develop a forecasting system that can mitigate the impacts of such events and keep the electrons flowing.
