Solar-C(EUVST)是由美国和欧洲国家做出重大贡献的下一项日本太阳物理任务。这次飞行任务搭载了一台极紫外成像光谱仪，以一种名为EUVST(极紫外高通量光谱望远镜)的狭缝成像系统作为任务有效载荷，以迈出基本的一步，回答等离子体宇宙是如何产生和演化的，以及太阳如何影响地球和太阳系中的其他行星。2020年4月，日本宇宙航空研究开发机构(JAXA)的空间和宇航科学研究所(ISAS)为这次任务进行了最后的入选，这是2020年代中期用Epsilon运载火箭发射的一系列竞争性选择的M级任务中的第四次。美国国家航空航天局(NASA)已经为2019年9月的A阶段概念研究选择了这一任务概念，并正在进行最终选择。对于欧洲国家，该小组已经(或正在确认)国家机构对向EUVST提供的硬件捐助的确认认可。该飞行任务仪器的最新更新是增加了用于EUVST校准和科学目的的紫外光谱辐照度监测能力。本专题介绍介绍了该飞行任务的最新情况，并对该飞行任务的概念作了总体描述，着重说明了该飞行任务在2020年代中期以来在太阳物理研究中的关键作用。
Solar-C (EUVST) is the next Japanese solar physics mission to be developed with significant contributions from US and European countries. The mission carries an EUV imaging spectrometer with slit-jaw imaging system called EUVST (EUV High-Throughput Spectroscopic Telescope) as the mission payload, to take a fundamental step towards answering how the plasma universe is created and evolves and how the Sun influences the Earth and other planets in our solar system. In April 2020, ISAS (Institute of Space and Astronautical Science) of JAXA (Japan Aerospace Exploration Agency) has made the final down-selection for this mission as the 4th in the series of competitively chosen M-class mission to be launched with an Epsilon launch vehicle in mid 2020s. NASA (National Aeronautics and Space Administration) has selected this mission concept for Phase A concept study in September 2019 and is in the process leading to final selection. For European countries, the team has (or is in the process of confirming) confirmed endorsement for hardware contributions to the EUVST from the national agencies. A recent update to the mission instrumentation is to add a UV spectral irradiance monitor capability for EUVST calibration and scientific purpose. This presentation provides the latest status of the mission with an overall description of the mission concept emphasizing on key roles of the mission in heliophysics research from mid 2020s.
