The Earth's radiation belts have fascinated and puzzled scientists for more than 50 years. Scientists know that extremely energetic electrons and protons are trapped in the geomagnetic field, but how did they get so energetic? Measurements show that the radiation belts can change in intensity by many orders of magnitude, but what makes them change so dramatically? Solar activity and interplanetary disturbances affect the belts' structure and characteristics, but what are the processes that connect cause to effect? Researchers do not yet have answers to these fundamental questions. However, recent observational and theoretical work has led to a growing consensus on the new directions in radiation belt research that will be the key to answering these questions.
