摘要

Two new NASA probes that are flying through the belts of radiation surrounding Earth have found that these regions change more rapidly than previously thought. The Van Allen Probes - a pair of twin spacecraft formerly known as the Radiation Belt Storm Probes - launched Aug. 30, and turned on their instruments two days later. Since then, the spacecraft have returned unprecedented measurements of the zones of charged particles, called the Van Allen radiation belts, around our planet. In these zones, trillions of high-energy particles released by the sun are trapped by Earth's magnetic field. "We've all been just amazed at the tremendous results that we've seen even at this early date," deputy project scientist Nikki Fox of the Johns Hopkins University Applied Physics Laboratory said Dec. 4 during a press conference at the annual meeting of the American Geophysical Union in San Francisco.
