There is a dangerous radiation belts around Earth. To explore this zone NASA launched a spacecraft six and a half years ago which is constantly moving through this belts and now it entered in the last phase of discovery in Earth’s dangerous radiation zone.
“The Van Allen Probes mission has done a tremendous job in characterizing the radiation belts and providing us with the comprehensive information needed to deduce what is going on in them,” said David Sibeck, mission scientist for the Van Allen Probes at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “The very survival of these spacecraft and all their instruments, virtually unscathed, after all these years is an accomplishment and a lesson learned on how to design spacecraft.”
