欧洲空间局在空间安全领域布局守望者号空间天气专用业务卫星，成为全球空间天气研究预报和服务领域的里程碑事件之一。指出利用日地拉格朗日L5点开展空间天气监测预警具有独特优势，简述了守望者号任务目标和有效载荷配置，回顾了其漫长的推进历程、未来实施计划及美国积极参与守望者号任务的情况。提出中国须高度重视空间天气对经济社会发展和空间安全的影响，努力抢占空间科技制高点，坚持底线思维和极限思维，积极推进中国自主空间天气天基监测系统的发展。
European Space Agency decides to develop the space weather mission Vigil as its first dedicated operational satellite in the Space Safety Program, which is a milestone in the field of global space weather research, forecast and services. This paper describes the unique advantages of Vigil mission in monitoring and forecasting space weather at the L5 point of the Sun-Earth system, and briefly addresses its objective and payload. Its long formulation process and future implementation plan are reviewed, as well as the active participation of the United States in the mission. It is pointed out that China must pay more attentions to the negative impacts of space weather on economic and social development and space security, and actively promote the development of an independent national space weather space-based monitoring system.
