面向近地小行星防御验证的协同监测任务分析与设计

Analysis and design of cooperative monitoring mission for near-Earth asteroids defense verification

  • 摘要: 协同监测任务通过全过程链条测定小行星轨道并监测撞击过程,可有效评估以动能撞击手段进行小行星防御的效能,是实施近地小行星防御演示验证任务的关键环节。文章在全面调研“双小行星重定向测试”(DART)任务的评估特点和协同监测情况的基础上,面向我国近地小行星防御演示验证任务,综合分析我国现有地基、天基监测能力以及协同监测任务的特点,按照“远探、近监、回看、联测”的思路设计协同监测任务方案,并梳理出需要攻克的关键技术。最后,从推进监测能力体系建设、深化拓展国际交流合作等方面提出启示与建议,以期为我国未来近地小行星防御演示验证任务论证实施以及天地协同的监测预警能力体系建设提供支撑。

     

    Abstract: Cooperative monitoring missions determine the orbits of asteroids and monitor their impact processes through an entire process chain, by which the effectiveness of the usage of kinetic energy impact means for asteroid defense can be evaluated. They are key links in the demonstration and verification mission for near-Earth asteroid defense. In this paper, the evaluation characteristics and cooperative monitoring of Double Asteroid Redirection Test (DART) missions were surveyed, based on which the ground-based and space-based monitoring capabilities, and the characteristics of cooperative monitoring missions of China were comprehensively analyzed focusing on the China’s near-Earth asteroids defense demonstration and verification. A cooperative monitoring mission scheme was designed on the concept of “remote exploration, approaching observation, post evaluation, and joint testing”, with relevant key technologies identified. Finally, some enligntenments and suggestions were proposed in promoting the construction of the monitoring capacity system, as well as deepening and expanding international exchanges and cooperations. This work may provide support for the demonstration and verification of future China’s near-Earth asteroid defense, further for the construction of cooperative monitoring and warning capability system.
