The Solar wind Magnetosphere Ionosphere Link Explorer (SMILE) was proposed to the Chinese Academy of Science (CAS) and the European Space Agency (ESA) following a joint call for science missions issued in January 2015. SMILE was proposed by a team of European and Chinese scientists, led by two mission Co-PIs, one from China and one from Europe. SMILE was selected in June 2015, and its budget adopted by the Chinese Academy of Sciences in November 2016 and the ESA Science Programme Committee in March 2019, respectively. SMILE will investigate the connection between the Sun and the Earth using a new technique that will image the magnetopause and polar cusps: the key regions where the solar wind impinges on Earth's magnetic field. Simultaneously, SMILE will image the auroras borealis in an ultraviolet waveband, providing long-duration continuous observations of the northern polar regions. In addition, the ion and magnetic field characteristics of the magnetospheric lobes, magnetosheath and solar wind will be measured by the in-situ instrument package. Here, we present the science goals, instruments and planned orbit. In addition the Working Groups that are supporting the preparation of the mission and the coordination with other magnetospheric missions are described.
太阳风-磁层-电离层连接探测器（SMILE）是在2015年1月联合发布科学任务征集令后，由欧洲和中国科学家团队向中国科学院（CAS）和欧洲航天局（ESA）提议的。SMILE由一个欧洲和中国科学家团队提议，由两位任务联合首席研究员领导，一位来自中国，一位来自欧洲。SMILE于2015年6月被选中，其预算分别于2016年11月被中国科学院和2019年3月被ESA科学计划委员会批准。SMILE将使用一种新技术来研究太阳与地球之间的联系，该技术将对磁层顶和极尖区成像：太阳风撞击地球磁场的关键区域。同时，SMILE将在紫外波段对北极光成像，提供对北极地区的长时间连续观测。此外，磁层叶、磁鞘和太阳风的离子和磁场特性将由原位仪器包进行测量。在此，我们介绍科学目标、仪器和计划轨道。此外，还描述了支持任务准备和与其他磁层任务协调的工作组。
