I've just started at http://rockettube.fun/ rokettube On October 9, 2012, while flying through the radiation belts, the Van Allen Probes measured a sudden, nearly thousand-fold increase in the energy of electrons within the outer belt. The rapid increase came on the heels of a period of waning energies the week before. The October 9 event mimicked an observed, but poorly understood event measured in 1997 by another spacecraft. Ever since the 1997 event, scientists have pondered whether the increase in electron energy was the result of forces outside of the belts, a mechanism known as "radial acceleration," or from forces within the belts, known as "local acceleration." Data from the Van Allen Probes seems to put this question to rest.
