NASA网站3月15日报道,利用范艾伦探测器(VAP)数据,科学家发现内辐射带的相对论电子数量低于预期,可能有助于设计更廉价的航天器。相关论文发表在Journal of Geophysical Research:Space Physics上。以往的空间任务无法区分内辐射带中的高能质子和电子。利用VAP搭载的磁电子和离子光谱仪(MagEIS),科学家首次排除了高能质子的影响,并发现内辐射带大多数时候不包含相对论电子,这与 NASA’s Web site reported on March 15 that using Van Allen probes (VAP) data, scientists have found that the lower than expected number of relativistic electrons in the inner radiating band may help to design cheaper spacecraft. Related papers published in the Journal of Geophysical Research: Space Physics. Past space missions can not distinguish between high-energy protons and electrons in the inner radiation band. Using VAP-equipped MagEIS and MagEIS, scientists for the first time excluded the effects of high-energy protons and found that most of the internal radiation does not contain relativistic electrons,
