The International Sun-Earth Explorer is a three-spacecraft program of the National Aeronautics and Space Administration and the European Space Agency aimed at securing a more quantitative knowledge of the structure and stability of the magnetosphere. One spacecraft (ISEE-C) makes observations in the solar wind upstream of the earth, while the other two (ISEE-A and ISEE-B), in the same highly eccentric orbit but separated by a relatively small variable distance, observe inside the magnetosphere. This international program is concurrent with the International Magnetospheric Study, to which ISEE-A and ISEE-C form a large U.S. contribution. The scientific aims and technological methods are discussed.
国际日地探测者是美国国家航空航天局和欧洲航天局的一个三航天器计划，旨在更定量地了解磁层的结构和稳定性。一艘航天器（ISEE-C）在地球上游的太阳风中进行观测，而另外两艘（ISEE-A 和 ISEE-B）则在相同的高偏心轨道上，但相隔相对较小的可变距离，在磁层内进行观测。这个国际计划与国际磁层研究同时进行，ISEE-A 和 ISEE-C 是美国在该研究中的重要贡献。本文讨论了该计划的科学目标和技术方法。
