Successful Liftoff Begins Unprecedented Study of Radiation Belts

NASA's two-year Van Allen Probes mission began Aug. 30, 2012 with an early morning launch from Space Launch Complex-41 on Florida's Cape Canaveral Air Force Station. The twin probes rode into orbit aboard a United Launch Alliance Atlas V rocket after a smooth countdown that saw no significant technical problems or weather concerns.
