The Status of NASA Mars 2020 Rover Landing Site Selection and Some Thoughts on the Landing Part of China 2020 Mars Mission

  • 摘要: 总结了近20年来火星探测的重要发现以及生命、气候和地质3个方面尚未解决的关键科学问题;介绍了美国国家航空航天局(NASA)2020火星探测任务的科学目标、科学载荷和着陆区选择的工程条件限制,并重点分析了经过3次着陆区选择研讨会,上百位行星科学家投票选取的排名前3的预选着陆区的地质情况。在此基础上,提出了对我国2020年火星任务的着陆探测部分的一些思考,并根据不同的任务目标(聚焦生命、气候和地质问题;支持载人火星探测的资源勘察;工程技术验证)提出了3个候选着陆区。

     

    Abstract: The important discoveries of Mars exploration in the past 20 years and the major unsolved questions on Martian life, climate and geology were reviewed. The scientific goals, payloads information and engineering constrains of the National Aeronautics and Space Administration (NASA) 2020 Mars mission were presented. In addition, the geologic characteristics of the top 8 candidate landing sites selected by hundreds of planetary scientists in three landing site selection workshops were described. Three candidate landing zones for China's 2020 Mars mission were proposed based on the different mission goals: 1) addressing key life, climate and geology questions; 2) resource reconnaissance for future human missions; 3) engineering demonstration.
