AI 中文摘要
SOLAR-C 是一项由日本宇宙航空研究开发机构（JAXA）牵头的国际太阳观测卫星任务。该任务旨在通过极紫外（EUV）光谱学阐明太阳大气中的质量与能量输运。任务搭载了极紫外高通量光谱望远镜（EUVST）和太阳光谱辐照度监测仪（SoSpIM），能够在宽温度范围（10^4 K 至 10^7 K）内以最小温度间隙和高时空分辨率实现综合观测。为实现关于大气加热和太阳耀斑爆发的科学目标，SOLAR-C 在继承 Hinode 和 IRIS 卫星遗产的基础上，实施了灵活且响应迅速的运行流程和数据处理系统。首席观测者会创建观测时间表，其中包含核心观测计划和已批准的建议计划，同时考虑太阳活动水平。航天器上采用 SpaceWire 通信架构，并实现了一种方法，即在数据传输期间由任务仪器临时充当网络主控，以支持高数据速率要求。遥测数据在世界各地的地面站下行传输，并汇集于 JAXA 宇宙科学研究所。EUVST 数据在名古屋大学的 SOLAR-C 科学中心进行校准，而 SoSpIM 数据则在处理与归档设施进行校准，之后整合为科学数据产品。这些数据将立即公开。该任务的一体化运行方案有望增进我们对太阳大气加热和耀斑过程的理解。
英文摘要
SOLAR-C is an international solar-observing satellite mission led by Japan Aerospace Exploration Agency (JAXA). It aims to elucidate mass and energy transport in solar atmospheres through extreme ultraviolet (EUV) spectroscopy. The mission carries the EUV High-throughput Spectroscopic Telescope (EUVST) and the Solar Spectral Irradiance Monitor (SoSpIM), enabling comprehensive observations across a wide temperature range (10^4 K to 10^7 K) with minimum temperature gaps and high spatial and temporal resolution. To achieve its science objectives regarding atmospheric heating and solar flare eruptions, SOLAR-C implements a flexible and responsive operational procedure and a data processing system, while building on the heritage of the Hinode and IRIS satellites. The Chief Observer creates observation timelines that include core observation plans and approved proposed plans while taking into account the solar activity levels. A SpaceWire communication architecture is employed onboard the spacecraft, and a method is implemented in which the mission instrument temporarily acts as the network master during data transfer to support the high data rate requirements. Telemetry is downlinked at ground stations worldwide and gathered at the Institute of Space and Astronautical Science, JAXA. The EUVST data are calibrated at the SOLAR-C Science Center at Nagoya University, while the SoSpIM data are calibrated at the Processing and Archiving Facility before being integrated into the science data products. The data will be made publicly available immediately. The integrated operational scheme for this mission is expected to advance our understanding of solar atmospheric heating and flare processes.
