摘要
在对可能存在生命的目标天体进行探测活动中,既要满足国内外已形成的行星保护政策要求,又需要在工程研制进度、成本与科学研究效果之间找到最佳平衡状态。通过结合现有深空探测任务的研制流程,将各项行星保护工作嵌入其中,研究两者的匹配性,以最严格的V类限制性返回任务为例,梳理出行星保护工作5个阶段的推进流程,并识别出其中的关键措施。研究表明:高类别的行星保护工作与探测器的研制存在强耦合关系,会严重减缓整个工程的研制进度,提高工程的研制成本。合理规划行星保护工作在深空探测任务研制中的切入点,改进和优化行星保护关键技术,在进度、成本与效果之间达到更好的平衡状态,最终避免目标天体与地球之间交叉生物污染事件的发生。
In the exploration activities of target celestial bodies that may contain life,it is necessary not only to meet the requirements of planetary protection policies that have been established both domestically and internationally,but also to find the optimal balance among the engineering development progress,cost,and scientific resarch effectiveness.In this paper,the compatibility of the development process of existing deep space exploration missions and various planetary protection tasks are studied.Taking the strictest V-class restricted return mission as an example,the advancement process of five stages for the planetary protection work is sorted out,and the key measures are identified.The results show that there is a strong coupling relationship between the high-grade planetary protection work and the development of spacecrafts,which will seriously slow down the entire engineering development schedule and increase the engineering development cost.To achieve a better balance among the schedule,cost,and effectiveness and avoid the occurrence of cross biological pollution events between the target celestial bodies and the Earth,the entry point of the planetary protection work in the development of deep space exploration missions should be reasonably planned,and the key technologies for planetary protection should be improved and optimized.
