The Mars Exploration Program Analysis Group (MEPAG) maintains a standing document that articulates scientific community goals, objectives, and priorities for mission-enabled Mars science. Each of the goals articulated within the document is periodically revisited and updated. The astrobiology-related Goal One, "Determine if life ever arose on Mars," has recently undergone such revision. The finalized revision, which appears in the version of the MEPAG Goals Document posted on September 24, 2010, is presented here.
火星探索计划分析小组（MEPAG）维护着一份常设文件，阐述了科学界对任务驱动的火星科学的目标、宗旨和优先事项。该文件中阐述的每一个目标都定期进行回顾和更新。与天体生物学相关的目标一“确定火星上是否曾经有生命存在”最近就进行了这样的修订。2010 年 9 月 24 日发布的 MEPAG 目标文件版本中出现了最终修订版，现呈现如下。
