摘要:

XRISM是由日本宇宙航空研究开发机构、美国航天局、欧空局和其他国际参与者共同执行的X射线天文学飞行任务,计划于2022年(日本财政年度)发射,以快速恢复天体物理物体的高分辨率X射线光谱学。为了提高飞行任务的科学产出,科学操作团队(SOT)的结构独立于仪器团队和飞行任务操作团队。SOT的职责分为四类:1)访客观察员计划和数据分发,2)分析软件和校准数据库分发,3)访客观察员支持活动,以及4)性能验证和优化活动。作为第一步,从过去的日本X射线任务的科学运作的经验教训进行了审查,并确定了15种教训。其中,a)从地面阶段及早准备操作的重要性,b)建立独立于仪器开发的科学操作团队,以及c)由指定成员明确界定职责的操作被认为是关键的经验教训。然后,团队结构和任务和科学操作之间的任务分工被定义;任务在日本,美国和欧洲之间共享,并分别由SOC,SDC和ESAC三个中心执行。SOC被设计为执行接近航天器操作的任务,例如航天器规划、快速查看健康检查、预流水线处理等,SDC涵盖有关数据校准处理、分析工具维护等任务。SOC和SDC均涵盖数据存档和用户支持活动。最后,在发射前确定和准备科学行动的任务和工具。

英文摘要:

XRISM is an X-ray astronomical mission by the JAXA, NASA, ESA and other international participants, that is planned for launch in 2022 (Japanese fiscal year), to quickly restore high-resolution X-ray spectroscopy of astrophysical objects. To enhance the scientific outputs of the mission, the Science Operations Team (SOT) is structured independently from the instrument teams and the Mission Operations Team. The responsibilities of the SOT are divided into four categories: 1) guest observer program and data distributions, 2) distribution of analysis software and the calibration database, 3) guest observer support activities, and 4) performance verification and optimization activities. As the first step, lessons on the science operations learned from past Japanese X-ray missions are reviewed, and 15 kinds of lessons are identified. Among them, a) the importance of early preparation of the operations from the ground stage, b) construction of an independent team for science operations separate from the instrument development, and c) operations with well-defined duties by appointed members are recognized as key lessons. Then, the team structure and the task division between the mission and science operations are defined; the tasks are shared among Japan, US, and Europe and are performed by three centers, the SOC, SDC, and ESAC, respectively. The SOC is designed to perform tasks close to the spacecraft operations, such as spacecraft planning, quick-look health checks, pre-pipeline processing, etc., and the SDC covers tasks regarding data calibration processing, maintenance of analysis tools, etc. The data-archive and user-support activities are covered both by the SOC and SDC. Finally, the science-operations tasks and tools are defined and prepared before launch.
